That's right, Adam, don't fight it..........focus........you're eyes are fast becoming affixed to the center of that vertically bobbing craft............the tension leaves your hands and you marvel that your thumbs move as if they have a mind of their own.......focus......time and motion begins to slow down as you become one with your plane.........focus...........you hear the sound of your even breathing........observe how time stops as the plane hangs motionless, only inches from the ground............an even stream of blue/gray smoke pummeling the grass and enveloping the center of your attention.........all your senses are heightened......alert..........then..........."HEY MISTER! HOW MUCH DID THAT COST? CAN I TRY? I KNOW A KID THAT CAN FLY BETTER THAN THAT! HOW FAST DOES IT GO? HAVE YOU EVER CRASHED IT? HOW HIGH WILL IT GO? FLY IT TILL YOU CAN'T SEE IT!" So much for the Zen thing.

Jack delivered 16 gallons of fuel to me at the field last night, so I don't have to be so stingy anymore. Now I can fly 8 hrs a day instead of just 6! Well, after I'm finished with "the kitchen from Hell", anyway. Countertops, here I come.

Peace,

Downtrodden.

lol Downtrodden -- I had a similar experience the other day , but I was trying to land a corsair that had a dead throttle servo, stuck at 1/4 throttle. Too fast to just plop it down, and not quite enough to do a go around with any authority.

As I make my first final attempt, and realize it hasn't throttled back one of the electric/foamy/micro heli guys come up to me and starts asking me about what engine I think he should put in a funtana if he gets one, cause his brother works in a hobbyshop - Here's how my brain was processing info cause he wouldn't shut up, even though I was clearly having problems with the plane I had in the air. I did not respond to any of his conversation during this whole thing.

Ok- on final, throttle back - hrm, my plane won't slow down, now I've overshot the runway, throttle up and expect to pull out, but what's this, now it won't throttle up, hmm ok I think it's still flying need to be really gentle to keep it from stalling, ....do you think I need I need to put brand x servos in that Funtana, cause someone told me that they need a strong servo....good - plane is gaining a little altitude - circle around to the left - too much wind to come in downwind, so I'm gonna need to get it all the way back around, 30 ft altitude, just don't bank it too much and stall......and i think I might go electric on that funtana, what do you think about the Axi blabbity blah blah blah, with an 80 amp ESC....ok still turning - Holy crap where did the telephone poles come from??? Those weren't here last time I flew at this field?? - hmm - I just flew between 2 of them I think, keep on climbing.....Yeah I'm thinking of recovering the funtana to make it look like a warbird, cause I like the look of the P-51....ok turning on final, does my throttle kill still work? No, must be the servo then. welp I'm gonna have to put it in fast and pray be ready to put on high rate ele once it......and I think I'll just put a Saito 125 on that plane cause it's supposed to weigh 10 lbs, and it should hover it real nice....ok 3 feet, touchdown , man it's rolling out fast.....anyway I'm not sure I want the funtana or a new heli....high rate ele switch see if I can keep the tail on the ground (bumpy runway)......but if I goit a new heli...Bah - plane caught a bump and flipped nose over tail--hope it's not damaged.....hey man -why'd your plane flip over like that?

You're killing me Chris. I'm reminded of a flight I had when I was just starting out. The desert around the dry lake I fly at is grazed by cattle in the spring. The cattle had been moved up to the high country a few days earlier, but the blood sucking biting horse flies had stayed behind. I took off on my first flight of the day, and was immediately swarmed by these Mini-Twists. I was pretty green as a pilot, and needed every bit of concentration to fly the plane. These flies land, then bite the crap out of you. My theory was if I kept moving and wiggling, they wouldn't land. I danced a combination of the Funky Chicken and Watusi until I could bring it around and bounce it to a halt. While still dancing and swatting at the flies with my hat, I disassembled my plane and beat a retreat to the house.

[:@] Still haven't maidened the Twist. It's sitting in the workshop looking like a lovely yellow jewel, waiting for the right combination of time and weather. Still, I did start flying my new micro heli yesterday which was fun.

Anyway, just posting because I came across this short (but quite neat) video of the PNP:

All you guys are a riot

You make me laugh my A## off, Yes don't you just love those flying distractions, I have to laugh when people are talking to me when I'm trying out stuff, so the best way to clear the air is a nice vertical high speed pass about 5 feet away from me and the "Talker" [>:][>:] that will usually get a HOLY CRAP out of the yapper and then he focuses on the plane for a while a little speechless.

Unfortuneatly I haven't figured out the way to fly without the "Miniture Twists" LOL, doing high speed fly byes and high speed biting on my arms and face at My house, our field seems bug free, but my house is next to a couple of farms and the Horse flies are a plenty. I'm thinking Serious Smoke system might work.

Good luck on that Counter DT, and a Happy voyage to you Jack.

Guys...I need your help and/or expertice here PLEASE!![]

I am about to return my Supertigre .51 to the service center..but will wait for your response before I do so....

The reason I place this message here, is I too have a Twist 3D, and decided to put a Supertigre v.51 ringed engine in it. I hope some of you guys might be able to help me out here.

I bought this engine brand new two weeks ago....so far.....nothing but trouble.

The current issue with this enigne is, the engine will NOT pull fuel from the tank to the carb. The club flight instructor and I have checked and changed the fuel tubing...no result.
The tank was removed and temporarily held above the fuselage (to get it above the carb entree)...the engine fired up immediatley!!
Placed back in the fuselage, it will not pull fuel into the carb......
I use the standard muffler...no after market muffler or so.

When!! the engine is running...it gets way too hot too quick!!
Although the manual asks to break in the engine full throttle...this is not possible with this engine, since it will get so hot it
seizes....Different glowplugs were used to see if it made a difference...no result. Needles were adjusted cautiously....no result.
Carb and needles were checked for possible errors....they all seem to be fine!!

Both flight instructors have spent several hours checking this engine...both of them were unable to determine the error causing the engine not to pull fuel and the quick increase in temperature of the engine...[:@]

Both of the instructors however....use Supertigre engines themselves...flying a Twist 3D and a UcanDo 3D with no issues whatsoever.

I depleted my options for as far as resolving my problems with this engine. I have a OMP Katana on the shelves, waiting for an engine...right now, I am not sure if I will equip it as well with a Supertigre engine...

If you guys have advice for me (before I return it to the service center), PLEASE let me know.....[]

dutch, I know you probably have already checked this, but the pressure fitting on the muffler might be plugged. Remove the line to the muffler and blow in it. Fuel should run out the disconnected line on the carb. Another thing to check is for trash plugging the spray bar. Remove the high speed needle and check for blockage. It's running hot from too lean a fuel mixture. It's starving for fuel at high rpm's.

Tim, thank you so much for your tips...unfortunately..both we did! blowing through the tube..fuel is running out without a problem. Spraybar was blown out with high pressure air....[]..no blokkage was found...again..thanks Tim..I appreciate any help right now.....

At this moment, for the very 1st time..the word "electric conversion" crossed my mind....[]

NO NO NO NO electric conversion !!!!! OS MAX

I know I repeat some of things other people say on the thread, but I feel when someone reads the same advice given by a few people, that it helps them decide to take that advice of what we all agree on. for most of us have been through these problems countless times, but even the newest of people can point out something overlooked by an experienced problem solver, after all, we are all human. ummmm Except Jack & DT,, they make me wonder sometimes... LOL

I'm thinking the same way as TimC, I would pull the needle valve and see if the spray bar is plugged, or maybe the needle is even bent a little blocking the hole at the point you probably need it at.

So Go with the TimC advice first, Maybe you guys maybe already have done that, but who knows, sometimes the dummest little thing will prevent it from working properly, and it sounds like a clogged line or valve, hole, somewhere. but with the tank working above the fuse just fine, I'm more inclined to think there is an Air leak somewhere, and it needs more gravity from the fuel to work right. maybe a carb screw is loose or there is a crack where the carb slides into the engine casing, or the needle valve area, check for cracks or a loose nut that holds on the valve, Check all the O rings on the needle and carb pieces, to make sure there not dry rotted or cracked or just seated wrong. and yes, the overheating is most undoubtably not enough fuel in there to help cool it down.


However the first thing I would have done was bought an OS Max, sorry,,, but I have known a few people to have problems with the Supertigres brand new out of the box, I want to get a ST 90 for my Jet & US 1000 because the price is so much more reasonable, but its the horror stories like yours that have kept me away, I hate engine problems right off the start. I also know people that have them and have no trouble at all. so to each his own I guess.


Good luck to you, I hope it is just something easy.

My SuperTigre .40 was a Jim Dandy and any brand can let a bad one slip through. Waldo is right about the needle valve probably being OK if it will run with the tank elevated. Fuel foaming is a possibility but would only show up with the tank partially full. If the leaning problem is there with a full tank, I think that would eleminate foaming problems. Is the needle valve a good snug fit in the housing? Is the 0-ring OK? If there was a pin hole somewhere in the fuel line, like Waldo says, elevating the tank would over-ride the pinhole leak and the engine would run normal. If you haven't already, it might pay to try new fuel line all the way from the tank to the carb. Some of the folks here at RCU live and breathe SuperTigres. You might post your problems as a new thread in the "glow engine" forum and you should be swamped with help. Good luck with it dutch. I wouldn't send it back until I had run it on a test stand. This would eliminate any problems caused by airframe vibration. If it runs good with the tank elevated above the model, I'd say there's probably nothing wrong with the engine.

I don't have to leave for a couple days, so I can keep reading you Twistoholics and giggle, and laugh, and cry.

Chris, I loved your story. Still laughing. But you brought her home. That's "aces" flying, lad. I had a throttle get frozen, iced, wide open and had to fly it until it ran out, then dead stick her in. What I didn't think to do was take 'er up high, way high, then dive at full throttle. The clunk comes out of the fuel, engine dies, and you've got nothing worse than a dead stick, for which you are prepared. I call it the 700 foot approach, straight down. I don't know if quarter throttle on that warbird will get you high enough, but with patience even an egg walks. Something to think about. We have long grass on the end of our mowed field--and that's a blessing. Stops a lot of run outs and runaways.

Boy, that ST .51 sounds like a real witch. I'm frankly glad it's your problem. [Said with GREAT sympathy.] I have my own probs with a ST .51, new, on the Voyager Long-EZ--the one that bit my finger. Because it's a pusher prop, it seems to pull all the fuel out of the carb--making the engine untunable. I thought I might have had it fixed, having made a reverse angle velocity stack for it, when it bit me. It's ready for a maiden tomorrow--with cowling (which OUGHT to solve the sucking fuel out of the carb problem).

I've had great success with the ST .45. That engine seems just built right: tunes easily, endures long, takes several props. But I think I've bought my last ST. I'm with Waldo: buy OS Max. I'm having trouble with the new Evo .46 on the PNP Twist. Last night I put the PNP up first, had the trouble (varying rpms at full throttle, despite richening), then went to the Goldberg 330, .50 OSSX. What a dream.

We RC fliers are about as diverse a group as you'll find. All the research we do, all the building we do, all the discussing the THINKING we do, how to, where to, and what to fly is critical, but it's all focused on what Adam was talking about, the moment when you can stop THINKING about flying and just FLY. That's precisely when you go into that "Zen" state, when nothing exists but you, the bird, the wind, the clouds and sky. Wow.

Something that works for me when I run into this type of problem is to pump fuel through the needle in the reverse direction for about 30 seconds. My ultra stick wouldnt draw its own fuel, so I pulled the remote needle hose off of the carb, and pumped fuel into it backwards. From experience on both cars and airplanes, it's usually something in the needle that makes it not work right. Also, make sure your tank isn't leaking or your exhaust isn't leaking. Put some RTV around the base of the carb also. Sometimes that'll do the trick.
-Eric

My advice with the Super Tigres........if you don't like to fiddle with engines............send it back, get the replacement, and sell it on Ebay or to someone you know is a tinkerer. Then take the money and buy and O.S. FX! Now remember, I'm NOT criticizing you for buying one I'm just relaying my opinion. Otherwise, replace the fuel lines, check the O-ring and if the spray bar is clear remove the pressurizing line from the muffler all together! If that doesn't work then I'd say you have a genuine factory reject! Hope this helps.


Peace,

Downtrodden.

I've got a ST G-51 on mine... but unfortunately I've only gotten about 3 hours on it. I've yet to have any problems with mine (except for a needle valve screw that I let loosen up and get lost). Customer service sent me a new screw kit for it for FREE.

Hello
If you want something that starts & runs GREAT, Go with Evolution. I have 2 - .45s, 1 - .46s & 2 -.61s & have only had 1 dead stick landing. One of the .45s broke the crank pin. Horizon Repaired it under warranty & had it back to me in 10 days. I'm done now.



_____________________________________

If you remember the 70s you weren't there

But of course its Friday night and going into Saturday morning, its Raining again, and is suppose to rain on and off for the next 5 days, seeing Jack and DT are just west of us maybe you guys can help.

You need to get everyone in your area together that flys, and get out there at the same time and try blowing the jet stream anyway but east, something has got to be done, if it is still raining tomorrow morning, that will be 5 Straight Saturday morning rain outs, and countless weeknight rainouts, I don't think I can take it much more, I have been constricted to promenading around the backyard with my electric FO Cap 580, as soon as the rain stops for a minute I get out there and get in a couple of flights, so I have to say at least I am flying. But I need the wide open field for my Twist again I do miss it so.. I have even taken the Twist off in my yard a few times but I need to have a Twist flight in the complete wide open so I can let her breathe again. I'm crossing my fingers for tomorrow.

Just had to vent again,,, sorry LOL

Dutch,

It's just an engine, so unless the design is known to have mechanical failure, I would work though the issues.

First of all you having a fuel/air problem. Either to much air (leaking) or to little fuel (obstruction).

Here is how I test for leaks. I hook up the exhaust nipple and needle valve to the fuel tank just like how you are going to run it. Then I open the carb, blow in the exhaust, then rotate the prop until the air is escaping though the carb. This means that piston is all the way down exposing both the intake and exhaust ports. With the piston down and air coming though the carb I now put my finger over the carb. What this is doing is putting pressure in the crankcase, tank, and all of your hoses. You might feel a little air leaking out though the front bearing but that is ok as long as it is very little. If your setup doesn't hold pressure figure out where the air is leaking from and fix it. A tiny little leak at the carb or needle o-ring will cause all sorts of strange problems.

To test for obstruction I typically hook up a tube to the needle valve, open the carb, and try to blow though the whole thing. If there is an obstruction you can detect it, but it's hard to describe. Perhaps the easiest way to get a feel for how little is too little is to try it on a known good engine. If the ST feels like it builds more pressure then there is something in the way. A couple of things it can be is the hole in the carb intake barb isn't lined up with the brass insert ([link=http://www.rcuniverse.com/forum/m_2290854/mpage_4/key_/tm.htm]read post 95 for more info[/link]) or it could be some junk in the carb/needle/tubing.

While I agree that the quality control of some cheaper engines isn't that great causing problems like this, they are almost always resolvable with a little work and understanding.

I run a magnum 70 4 stroke on my twist and while it did take some tuning and playing with different fuels/plugs to get it working right, it now turns a 14x4w at 9800 rpm which hauls the twist around quite well. Best of all, I only paid $125 for the engine.

Always remember the 7 P's: Piss Poor Preparation Promotes Piss Poor Performance.

It flies! It flies!

My virgin Twist took to the air twice today and it was great. The plane is very responsive and has a huge amount of power with the Super Tigre 45. I'm still having a little trouble with the engine but it wasn't too bad. The problem is that the carb has to be set to have an idle which is just slow enough not to pull the plane along, but which is lean enough to have good pick-up. The pick-up was still on the slow side today, so that needs veeeery slight leaning.

Anyway, the plane flew great even though it was pretty windy, and I really like it. I had it set up with reasonably high rates and it was very positive, though not twitchy.

Thanks for the recommendation guys, this plane is really nice!

Matthew

Congrats Matt,

Glad you are air born with the Twist, she is a great flying plane, even in the wind, The next time am able to fly my Twist is probably going to feel like a Maiden flight again.

Jack now that I think of it, I do I do I do miss the smell of dope thinner, I'm going to the LHS and buy some, My wife is always lighting candles or incense, I'm going to buy 5 jars of fuel proof dope and place them opened in strategic rooms of the house, [sm=spinnyeyes.gif] Then every where I walk I can be reminded of how I use to feel back in the wrapping rice papper days, no wonder I am so addicted to this hobby. [sm=bananahead.gif]

Dope thinner and open flames? Brave soul. Then our Alaskan friend here is advising giving an engine an exhalation job. No thanks! I've watched Jack try for hours to rid the taste of glow fuel from his mouth (cheap entertainment, I might add). Akschu, just how isolated are you up there?

I'm off to see Jack maiden the machine that slices, dices, and juliennes.......(his finger that is)........the Long EZ.........I'll give you my report when I get back from ER.

Then........the kitchen from Hell continues.............underlayment..........counte r caps.........trim...........touch up painting..................everything but the lenoleum........wish me luck.......the owner is going through menopause and taking me with her!!!!#@$#@$%^#$$%@$##%#$##


Peace,

Downtrodden

Way to go Matt!!!! [sm=RAINFRO.gif]

My 2 cents:

I have to 2 Super Tigres, and 4 O.S's. My .40 sized Super Tigre, I think it is a .46, is a decent runner when it runs. I have it on a trainer and I can't get it run under 1/4 throttle no matter how I putz with it. I still fly with it, I just kill the motor as I bring it in. The other Super Tigre is in an airboat. I out it in the boat because when it quits on me I don't have to worry about landing it. Enough said on that one.

My O.S.'s are a .25LA in a cub, a .40LA in a sport plane, .61fx in my Twist, and .61fx in my Harmon Rocket. They all run flawlessly, and I mean flawlessly. Every single one of them fire right up and run like a top. They all idle down to a crawl, and are smooth throughout the RPM spectrum. I would say the .40LA has about 200 tanks throught it, the .61's have about 75 flights, and the .25 has about 100 flights on it.

Based on my experience with these engines I would only buy O.S. engines. I feel they are worth the extra money. I am planning on a 4 stroke next. I have been considering Saito based on how many of you guys on here have them. I am not sure but O.S. four stroke is the way I am leaning now. Cost is pretty comparable, so why not go with the brand that I trust.

Sounds like a lot of guys have had good luck with the Super Tigres, and if they work for you, more power to you. They cetainly are inexpensive. Got to go fly the Twist. Have a good weekend guys.

Adam

Adam,
I have a Saito 80 and an OS 70 surpass II. Both are excellent engines. Since you have had good success with the OS line, I would stick with the OS. Both engines were flown in my Twist. The Saito seemed to be overpowered, and the OS has more than enough power. The OS 70 is in there now and will stay there as I think it is a good combination.

Waldo has the OS 70 in his as well and can give you more of a report on it than I as he has had more flying time on his. I have the same weather pattern as Waldo and it has been absolutely terrible around here for flying. At least he has gotten out in the yard or at night to fly something. I on the other hand have not due to workiong long hours at my job and this wonderful weather. The only stick time I have gotten lately is on G3 and that is starting to get old. G3 is good to keep the thumbs and reflexes in shape but it is not the same as the real thing. Have to see if I can get a nitro smelling candle to burn while on G3 or maybe go run some engines on the test stand just to get that nitro smell fix.

I have 4 Super Tigre motors, a .29, .40 (2), and a .61. The .40 and the .61 were finicky but since I changed my plug to an OS #8 and have been using Ritchie's Brew 15% an now Magnum 15% fuel I have not had any issues with these motors at all.

The .29 is over 20 years old and is still going strong. That is in my VK Cherokee Babe with the stock muffler. I did have to replace the needle valve assembly as it was leaking at the o ring on the needle vlave, which maybe the problem Dutch is having. Since the engine is so old I could not get just a needle valve with the O ring, so I had to replace the whole assembly. It was about three ago and I think it was $10 at the time. Money well spent.

I have a .40 still in the box and the other one is in my Thunder Tiger Giles 202 with a Pitts muffler.

The .61 is in my scratch built Tamecat, which is a trainer type plane that looks like an F-14. I replaced that ugly can muffler with an Ultrathrust from Performance specialites. Looks and sounds better and i picked up a couple hundred rpm as well.

Not nearly isolated enough.

Besides I would rather have glow fuel in my mouth than gas or worse, diesel, any day of the week. If you don't like it, get some nylon tubing to attach to the end of the muffler, but keep in mind your adding something to the system.
