I found the cure for floating!!! Mix in -20 of up ailerons (airbrakes) with -3 down elevator mix and it will take the lift right out of the wings on final. Mine floated right past me at about 6 feet on several occassions and I finally found this cure. The mix makes the plane very predictable on final and about 80% of the float goes away. It doesn't make it drop, just land managably. I'll just mount the BCMA stock and, if needed, add thrust adjustments later. Thanks for the tip!

Al,

That might be the cure for landing this thing with this new prop. I'll setup a landing switch that drops the idle, raises the ailerons and mixes in the elevator so one quick flip and I'm all setup.

Thank you for the tip, I'll give it a shot

Just in case the PM didn't work. ' http://media.putfile.com/Kyle-3Ding-My-CAP-232 '

That link does not work. There is no file extension or typical putfile database numbers that go with it. All I get is the typical putfile advertisments and where the video would be is a blank screen with a red "X" in the upper left corner

A search for the name you have here does not show the video

Sorry

I just watched it. If you like you can PM me your e-mail address and I'll send you the original video.

PM sent...

The link works now. I had to put it into brackets. Sorry

Anyways im nearly ready for the maiden flight of my 27% cap there is only one thing worrieing me and that my motor os.1.60 now when i fill the tank up ( 27oz ) the only way i know ehn its full is when fuel comes out of the exhaust now on my Dummmy fill up ( Making sure there no leaks ) im holding the "Vent line" and The "Carbie" line and when the tanks fill up, I have fuel comming out of both lines is this normal.?? My fill up line is underneath the plane also. the carbie line and the pill up line both have clunks on them and arnt twisted in anyways..
all ur help would be apppreciated, its probably nothing just Pre _ maiden nerves hope u guys can et my mind straight ")

I always use fueler valves and only have two lines into the tank. If you have three lines into your tank and you're filling the tank completely then fuel will eventually come out of both the carb line and the muffler vent line. There is nothing there to stop it. Sounds like your system is fine. If you install a fueler valve then you would only have two lines into the tank. One for muffler pressure (bent up towards the top of the tank) and the carb line with a clunk that attaches to the fueler valve which, in turn, attaches to the carb. With your system, the way you describe it, fuel should come out of all lines when the tank is full. You would then plug the fill line and as soon as you turn the engine over your muffler pressure line should push any fuel in that line back into the tank. With both systems it is normal for fuel to come out of the muffler when the tank is full.

AuusiePilot,

It's normal for fuel to come out by gravity and then siphoning of the fill and pressure lines when your lines are below the fuel tank. You must use a stopper to prevent fuel (and muffler pressure) to escape the tank. Check out these [link=http://www.slimlineproducts.com/f1_tank_setup2_1.pdf]instructions[/link] in how to rig different fuel systems for some more information. Good luck on your maiden.

Kostas1,

You can get the DA engines from Europe as well. I ordered mine from Toni Clark, Germany (http://www.toni-clark.com/). So no need to pay VAT or customs. Price is attractive comparing buying it from US as the VAT adds 22% in Finland and that takes the edge of cheap dollar agains euro.

Did you do your maiden yet? Hope it went as well as mine.

hey No i didnt get to maiden it, it was ready to go but i actually drank too much the night before and i felt too sick to fly, i was so upset. and next week im flying to perth to watch the red bull pylon racing so its going to have to wait 3 more weeks alwell more practice on the sim hehe,

i was just curuous too guys what do u think of this plane good enough to isntall a smoker, after my maiden i think im going to build another one of these beautiful birds though im going to install a bigger tank and also put a smaller tank in there ( 10 oz ) and install the saito 220 what do u guys think.???

Hey Aussie,

I am installing a smoke system on mine. I am going to use a 14oz fuel tank instead of the 24oz one, and an 11oz smoke fluid tank. That's only a one ounce penalty over the original setup. I will install the smoke fuel tank on the CG ( 5 1/4" ) which is located were GP recommends to install the receiver and receiver battery (see the addendum for radio installation when using a Glow engine).

In my case I am using an Evolution 45GX gas engine so the rudder and elevators servos should be fine in the tail. The receiver and receiver battery, as well as the throttle and choke servos will go where the rudder Pull-Pull servos normally go. Using two Hitec HS-5645MG's for elevators and one JR DS8611A for rudder I will probably end up mounting a pair of 2400mAh LiIon packs all the way to the front inside the engine box to get it balance.

I am building the smoke system out of scraps I had lying around. The flow controller is from a Slimline Showtime that has a leaky pump. The 12Vdc pump is from a TME Smoke Fluid Field Pump ($21.99); I will solder the noise trap capacitors and save some money. The battery is an old 11.1Vdc 2200mAh LiPo from my Mini Funtana. I need to order a TME High Volume check valve ($6.99), and some tubing and connectors. You can save yourself a lot of work and aggravation by purchasing a TME Deluxe Smoke pump from [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGVU1&P=]Tower[/link] for $92.99, and it comes with flow valve, tubing and High Volume check valve. The only caution with the TME pump is that you need to isolate the pump housing from heavy engine vibrations. Otherwise they tend to break at the screw mount lugs. By the way I am not 100%, as I understand Nitrile hose is more impervious to heat than neoprene hose. Does anyone know for sure which one will withstand more heat?

The Sullivan Sky Writer is another decent smoke pump. They are about $77 thru Tower. I have used one on my Edge with no problems, for about 2 years and a couple of gallons of smoke fluid. Airtech, in answer to your question about tubing, Sullivans instructions say to use neoprene because of "its resistance to heat". Makes sense since most auto installations use neoprene all around the engine.

I got the maiden flight made today. Weather was little bit misty and no snow at the moment in the southern part of Finland. DA-50 had a lot of power and plane responded to really small moves. No that the maiden is done I can take my time to look that all the things I done are done well. I already know couple of things that I need look and make more secure.

Vanguard,

Appreciate your information on the use of neoprene for the smoke system. I have found it very difficult to obtain Nitrile tubing so I need to use an alternative. Are you using the neoprene for the connection to the muffler? I used Tygon ounce on a two stroke .91 for the smoke line muffler connection and it kept on melting, and gas engines run much hotter than glow.

Do you use an additional flow regulator ( i.e. needle valve ) with the Sullivan system? Or does the Sullivan Sky Writer can be finely programmed through the radio to regulate flow? I have found out that when the pumps are driven at 100% one needs to make small flow adjustments so there is no wasted fluid. The TME system comes with a cheap line pinch screw to regulate flow which is almost worthless. A [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDG58&P=7]Perry Remote Needle Valve [/link] assembly provides very precise flow control, and much longer run times on the smoker. I was able to get over six minute runs out of a 10oz tank, and that was using a non-programmable flow pump.

Airtech, I used neoprene to the muffler. It has been on there thru 2 flying seasons, and about 300 flights, with no noticeable damage. The Sky Writer flow is progammed thru the radio. Makes it easy to adjust. This is the only smoke system I have experience with but I dont think I would try any other at this time. My Edge has a 16 ounce smoke tank in it. I have flown a 15 minute flight, with smoke on during manuevers only. There was still about 2 ounces of fluid left. I have never tried just turning it on, in flight, to see how long 16 ounces really last.

Airtech,

The Sullivan and TME deluxe version come with everything you need except for the tank and battery. They give you about a foot of neoprene for the muffler connection.

Basically it goes like this

You can use tygon for these steps

Tank -> pump inlet -> pump outlet -> check valve inlet

Neoprene goes next

check valve outlet -> muffler.

I usually use a 2 or 3 inch piece between the check valve and muffler. It's just long enough to keep the check valve away from the heat.

You can use the neoprene in the tank but I usually do not. I replace all my fuel lines every season so I just do the smoke systems at the same time. I know that's a bit overkill but A) Tygon gets stiff over time B) Neoprene gets slippery in the tank and brittle from the heat at the muffler after about a year. I'd rather spend 30 dollars on a roll of tygon and another 30 dollars on a roll of neoprene than have to try to clean up fuel/smoke oil. If you ever have to do that once you'll understands what I'm sayin' [:'(][&:]

Thank you much Vanguard. I have two Showtime pumps, but neither one works. The controllers seems to be toasted. I think I am going to go with the TME SmartSmoker Simple Smoke Pump and add a Perry Remote Needle Valve to it. At $90 some bucks they are not exactly cheap. Maybe the Sky Wrriter is the way to go.

I am defenitely using the Neoprene for the mufler conection, between the check valve and the injector nipple. Thanks for the information.

Hey Bubba

That's a great idea.most "engine" problems I have see have been caused by the fuel systems not delivering fuel. And the mess a spill will do coud prove to be nasty. That's the reason I purchase my fuel tubing (Tygon and Silicone for the glow engines) by the 50' rolls. Is much sheaper this way.

Thanks for the detailed instructions on how to plumb the system, I found [link=http://www.slimlineproducts.com/Showtime_Instruction_Manual.pdf]these[/link] instruction on the Slimline Web. Because this set-up instructions was the reason why I was looking for Nitrilr Tubing.

hya guys again, i was wondering what u guys thought of a good 3d prop for the os 1.60???
im a bit undecided which on to go with?? 18x6 or 18x 8 and which company to buy from

Aussie,

I just answered your PM but I'll post it here for all to see

Here is a video of him with that plane/engine/prop combo that got him third place in a video contest

http://www.hiddenhangarrc.com/video/...vincentcap.wmv

Nice video Bubba. Shows how awesome the 3D performance of this plane is.

I decided on purchasing this model after seeing Jason Noll fly his factory sponsored electric powered version. He didn't flew any 3D, strictly IMAC maneuvers demo, and it flies fantastically with electric power. Vey light wing loading makes a big difference.

Happy Thanksgiving to everyone in this thread
