Which killer deal?

What do you want? A pattern plane or pylon racer? I don't think my Hanno could be squeezed into this little plane..... it only has 55" wings. It is designed for something like my O S .32 SX, a Webra .32, TT .36 pro or one of the new crop of .50 4 strokes. A .46 size 2 stroke would be on the large size but would be better.

re: Hirobo Stream 50 ARF

I was hoping that since it takes the ys 63 it could take the Hanno.
...all in the name of speed and fun. I already have a pattern plane (see earlier post). I may put the Hanno in it and put the RF in this. Is the ys 63 w tuned pipe lighter?

The current trend seems to be to put 1.60 2 strokes in 72" planes.

Per site:
"The model can also accept either standard exhaust systems or the "tune pipe down the center of the fuselage"

Just looking at Morris Hobbies web page. They carry MVVS 2 strokes. Most are convertable to rear or side exhaust. This could be a plus for someone looking at a rear exhaust pattern plane and a new engine.

There is also Jett Engineering and Novarossi (see link) for rear exhaust motors. The folks at Jett tell me thier motors are designed for speed not slow pattern.....just the ticket for Ballistic Pattern. Here is the Novarossi -

The Novarossi looks as sexy as an engine could look. Would like to hear from someone with one of these motors. I think the Supertiger rear exhaust is still available also.

Don't mind me asking, but what is SPA?

The Senior Pattern Association flies planes and maneuvers from before January 1, 1976. No retracts, no pipes. The original concept was to keep things simple and cheap (no retracts, no pipes). We fly patterns with only center maneuvers. Last year, we flew eight contests in the southeast averaging about 30 pilots. There were also several SPA type events in other areas of the country. The competition is a bit more low key than regular pattern, and the planes considerably less sophisticated. I started flying SPA just to get more time in front of judges. Most of the guys I fly against will tell you I've improved because of it. I hardly ever invent maneuvers during a contest anymore.

Jeff, (northwoodscub) I have tried twice to e-mail you but it comes back as undeliverable. Do you have another e-mail address ?

This has really got me thinking about giving the retro trip ago.
I too started flying in the early 70S and was in awe of the guys flying pattern on the pipe.
Hell why not...but guys get with the program... modern engines should be a down grade...well at least using trad' engines should give you a points hike. I flew recently with a buddy and a 70inch pattern aeroplane powered by the .61/pipe Hanno special.
Holy smokers it wasn't lacking power.
When I was a kid it was the old Webra Speed .61 Owned one and loved it... If I get on this jive it's gotta be that engine... in a Mike Birch Capricorn.... Not to shabby.

Just buy vintage..
 

I just snagged a NIB Rossi 61 FIRE (the good one with the 2 piece case..I have the 2 piece and 1 piece case versions, and I like the 2 piece better) for $103 off *Bay. These are the Rossis that everybody remebers when the say "back when they used screaming Rossi's on pipes". Maybe not SPA material, but surely great for Ballistic Pattern! LOL

Yo, ChuckAuger....
 

Wazzup with those .61 FIRE Novarossi engines ?
Their like $239. with pipe....any good ? :confused:

Dave. :)

I have no idea..they sure look good, and NovaRossi has a good reputation, but I've never seen one.

Latest project -

Super Curare delux kit - NIB
B&D Air retracts - NIP
OS soft mount
OS 61 Hanno II pumped rear exhaust with red anodized Hanno Pipe and 2 headers (all new).

All gathered thanks to religiously monitoring RC Universe over the past year. Total cost $450 (including individual shipping charges). I'm a kid again. Almost afraid to put it all together due to collectability of it all. Nah. Got work to do.....

BPA sounds good to me. :)

I too have looked at the SPA but wasn't interested for a couple of reasons. First, couldn't find anyone in the area that was doing anything with SPA and second, I am a fan of the 75-85 vintage pattern planes. I have a NIB Dash 5 and YS 60 FIRE ready to get into the building cue. I am like others on the thread, I just like the old 75-85 pattern planes. Started flying pattern in the late 70's (in central and southern CA.) with a Kaos and a K&B 60. Really liked it. THen I moved up to T2A, Tipo (loved the plane with a OS 61 with an OS 1.08 FSR carb), Phoenix 8 Challenge 4 and a few others. I was never that great but I sure enjoyed the way the planes flew. TO this day I still like to fly "Ppattern" type planes over the 3D type of stuff. The friends of mine that got me into pattern were flying the Dash 5 with the YS 60 and I liked the combo so much that I found the a Dash 5 (NIB) in Denver back in the early 90's. I have the YS 60 (bought from one of the guys that taught me to fly pattern) that has been in the box since 1985. They are still in the box waiting! :( I sure wish the SPA would take a look at being more inclusive for the 75-85 vintage stuff. I too would like to compete in the SPA environment just cause it seems to be a little less pressure.

The closest thing you'll find to the days of old pattern days really cheap, is the Airborne models Intruder $165 bucks ARF. Now thats hard to beat. I flew the SPA last year with one and had a good time, however the daddy rabbit with its larger wing has a little advantage.
Once you get yourself trimmed for the gear down all the time its nothing to it because you know nothing different. My Killer Kaos with the OS 91 is so strong it can be hand launched, so power without the pipe ain't all bad. Mike give the SPA a try, leave the retracts down and put a performance specialities muffler on and your ready to go.

I don't know if any of you have heard of a slingshot but they make them here in australia. they are EXTREMELY fast eith the os 61's. I know someone who owns one and it takes up the whole field to land.

ballistic pattern plane for 45 RE engine?
 

I have a new ST X45 RE just itching to get out of the box. Thought about putting it on a racer, but a ballistic pattern plane sounds much more fun. Any ideas???

Also, where might I be able to get an extended header for the X45? The one I've got is less than an inch long (so to speak). Bolt spacing is 23mm.


Thanks,
Beau

I just received the Novarossi .50 w/ Ultrathrust muffler from Planet Hobby a few days ago. I'll post a review when I get it running a month or two. Putting it in a GP Tracer for now. It sure is one sweet looking engine though!!!

Beau

Re: ballistic pattern plane for 45 RE engine?
 

I bought a couple from Macs some time back..I have a pair of the X45 RE STs..and then I picked up one on Ebay for a X40 RE ST I have. I don't really want to sell it, but I would if you found a plane for your X45 and the only thing holding you back was a header.

Tweet, huh?? I haven't seen (or HEARD!!) a Tweet around here in a while...

Pics of my tiporare: 56 in wingspan + o.s. .46fx + macs header and tuned pipe + eclipse 7, taildragger, rudder kevlar pull-pull, very fast, no bad habits, very accuracy.

With respect.

I try again ! I fully understand you nostalgia, but will anyhow buzz up the discussions with a few facts. 1. A smaller plane with a noisy engine at a high RPM is always thought to be faster than a big, quiet plane with an engine at low RPM. 2. A fast (not very accurate) calculation of prop pitch and RPM reveals the following : A prop with 7" pitch at 15k idicates a speed of 44.5m/s = 160km/h, a prop with 13" pitch at 8k idicates a speed of 44.0m/s = 158km/h. Not that different, huh ! In addition comes the fact that the bigger prop is more efficient and will generate more 'overspeed' due to propeller lift than the smaller one. I did measure the speed of my OS-140RX-FI equiped ZN-line Alliance with a radar-gun during easter, in a shallow dive it was close to 220km/h ! The seemingly low speeds during todays F3A schedules is not due to lower speed of the models, but a result of the flying style that requires throttle management. Then the models is made to be able to fly well at lower speeds. Do not missunderstand me, if you have fun flying a 30+ year old design with a lower power to weigth ratio than todays norm, feel free. The whole ide of this sport is to have fun !

The difference between my Tai Ji with ys. 91 and my old Eclipse with OS 61 RF and tuned pipe is fun factor. I'll agree the Tai Ji is a better flying plane.

The best anology to owning these two planes is driving my two cars. I am fortunate enough to have a BMW 5 series. It will do everything better than my 1990 Miata. Faster, more comfortable, more stable, better handling. Somehow the Miata is more fun to drive.

Thanks for your comments, but i have fin whit a 30 years old pattern plane, i do knife horizontal eights, i push into a vertcal from a knife flight, very impressive spins, snap rolls, hands off recuperation, low speed landigns, long vertical flight whit too acuuracy in rudder, i was disapoint whit the weight to power ratio, this tiporare has a extra power for this weight, it's a smaller version 56 inch wingspan.

In my field the people tell me that waooo it's a tiporare?, looks great!!!, it's a 30 years old design!, but the modifications make the plane a different pattern style!, fly better than it looks!!

In fact, i do almost of the today pattern secuences, and the cost of the plane was the fourth of your alliance!.

I know your alliance it's a better plane, but my tipo it's a pure blood pattern plane!, whit more adrenaline!

Old 2 stroke pattern fun
 

Well, I got the bug again. I put a new Bluehead in my old Kaos. It flies as good as ever. I'm almost finished with a Tipo and a Mach 1

I almost sold my old pattern kits. Sure glad I didn't. If any of you guys from the Richmond, Virginia area are interested, we are in the process of building a first class model field ajacent to our private airport in Amelia County. The runway itself will be 700 to 800 feet X 100 feet.

With a small amount of effort, you can get the exhaust tucked under the Tracer tank compartment. I did it with a 46FX and Jett Stream muffler, which I believe is nearly identical to the ultrathrust. Although now I have a quiet pipe on it.

Old 2 stroke pattern fun
 

Jim....that is a sweet setup! How much does the head stick out of the cowl? The novarossi is a little taller than the OS. Did you just have to cut that notch in the firewall? What else did you do? I may go for it! More pics would be great.....

Thanks,
Beau

Old 2 stroke pattern fun
 

The head sticks out one inch.

Unfortunately I don't have more close up pictures of the muffler installation.

I did have to cut the notch out of the firewall, and make the tank compartment cover. I didn't find it too difficult, just a bit of ply as a sort of frame, and 1/32 inch ply to form the channel. There is enough space to put in a 10 ounce dubro tank. The tank center ends up aligned properly with the carb.

The extension is 1/2 inch. 3/4 would make things a bit less tight. The extension has the added benefit of lowering the tuning rpm of the exhuast a bit - which I view as more suitable for this type of plane. (The Jett is tuned at 15000 rpm)

Note, it is *not* tilted at a 45 degree angle. It is something less than 45. I just placed the engine over the firewall and estimated the position so that I could get the blind nuts in place before gluing the firewall to the fuse. Use a compass to draw a circle centered on the indicated engine center, and passing though the indicated (i.e. the punches on the die cut peice) blind nut holes. The location of the blind nuts for the rotated mount should fall on that circle to ensure the center does not move - if that makes any sense.

Old 2 stroke pattern fun
 

I really like it.....but the ole .50 is just too big to make it work and the ultrathrust will be too deep into the fuel tank area. Checked with the plans and didn't really like what I saw. Guess I'll just stick with the standard mounting. Maybe the idea will come in handy for a future project though.

RE: Just buy vintage..
 

I have a Superstar EP electric and Avistar 40 at home waiting to fly (stay with me here). Spent winter on a flight simulator, dusted off my Futaba radio. First radios were a World Engines Expert and Kraft systems. I have not built a model plane in 15+ years. Got the rc bug with my first issue of American Aircraft Modeler (December 1973), the cover featured Bob Violett's (BVM) 60 pattern plane Shrike. I still have the plans 31 years later, even though the fibreglass fuselage is unavailable. Maybe one day I will learn how to lay up a fibreglass fuselage. Had a sweet stick, falcon 56, kadet and sig kougar. Watched the senior pattern members fly dirty birdies, mach one's, saturns, Curare's. Etc. I just purchased plans for the Minare. Used google to translate the German to English.

I want to in the next few years, I hope to fly some of those models I saw as a teenager. ARF's are nice, I still get pleasure from building.

Happy Flying

RE: Just buy vintage..
 

Man, this thread brings back memories. I never flew that UFO, but it's still on the wall....with about 1/2" more dust :D

Great. Now you've got me wanting to build this Curare again.

RE: Old 2 stroke pattern fun
 

IMHO I think it is a truly a shame that a few people would want to take these absolutely beautiful, awesome, and timeless pattern designs and hack them into tail dragger abortions. These designs are from an era when pattern flying was a spectacular event and the pilot skills demonstrated with these designs were and still are incredible. Kudos to those of you that embrace the concept and fine nuances of these timeless machines and real pattern flying!

Thanks to the SPA real pattern flying is still alive! Mickey Walker deserves an award for what he has done with the SPA http://www.seniorpattern.com/planes.asp

RE: Just buy vintage..
 

Hey Guys.....

I've been trying to get my old Aurora back in the air (after collecting dust for about 12 years).

Anyone out there have a 1988 vintage short-stroke YS 60 RE in operating condition they may wish to part with ?
I have a long stroke and an OS 61 pumper, but neither will bolt directly in without me messing with the front end.

Drop me a PM or email

RE: Old 2 stroke pattern fun
 

Hi there,

The Tornado 88 plan 370 from the September of 68’ issue of RCM is a real good old school pattern plane. It’s the teal one next to the pool

The Dirty Birdy plan 602 from the June of 75’ is also a lot of fun. It’s the one with the black canopy.

I just got done with a Gitano plan 1165 from the April of 94’ issue of RCM. It has the plan form of a modern pattern plane and the one in the article used a the Hanio .61. How ever If you are serous about using a tuned pipe with this plane, have plug in wings, removing the pipe every time you remove the wings is a bad idea. I just installed a GMS .61 on its side and installed fixed gear to reduce the amount of “BS” I would have to go though to get it in the air. The plane is very completion ready for aircraft in its class. This is the red and white plane.

RE: Old 2 stroke pattern fun
 

Having originated all this nonsence, time for an update.

Bad news is my Eclipse is probably toast. The engine stumbled on takeoff and while the fuse is repairable the wings are badly hurt. The engine was getting low on compression, I figure over 12 gallons of fuel has run through it. I have a new piston and sleeve for it and will probably install new bearings.

The good news is I stumbled on this old thread while searching for information on my "new" Curare. It is an untouched original MK kit with fiberglass fuse, foam sheeted wing kit and "new" in package Spring Air retracts. It even has the speed brake flap option! Thinking of putting her together soon. Unfortunately I sold my Hanno motor but still have options.

Debating on whether to use my rear exhaust pumped os rf or I also have a nib side exhaust pumped os 61. Thoughts?
