Well I have officially entered the 25% club. I have been working on this beast for some time now and had my maiden flight on Saturday 5-30-09. It was such a nice flying plane that I pushed it harder on my first flight than I normally do. I am going to get some better footage soon but just wanted to share my excitement and see how many other foam fliers fly the big stuff also.

Cool! I was on my way there a while back, but never made it. What's the weight on your plane? The closest I got was 11lb. It was a EZ arf super chipmunk, 108 size. I got it used from a swap meet. The orginal owner had hacked up a old weed wacker engine and converted it. The engine was practically falling off, so I made a new mount and moved the engine back like 4 inches. It was my 1st and only plane that flew on gasoline. Amazing how clean gas is. Wow, did it fly like nothing I have ever flown before. And it was probably, like 3lb over weight. One day, I would really like to get there.

I am not sure on the weight, but I guess it is 14 - 18 lbs, it is a heavy beast. The motor I used was from hobby city the FLT 45 and for $150 it is a great deal! I love foam planes but there is something about how smooth and strait a heavy pane flies and the sound. The size is also something that would be hard to duplicate in foam.

 

Wow, that is a great deal for a engine! Looks like it will be even easier for me to get back into it, when the time comes. There's got to be some weird scaling factor, because I thought mine had way too much wing loading and under powered. But it tracked and just penetrated through the air really well. Did slow rolls without fall out of the sky. And I often overshoot the runway, expecting it to drop.

ET: Yea I hate the nitro clean up to, I am glad that the gasoline motors have very little clean up but I still get gas on my hands lol. The GP Sukhoi can go nitro, gas, or electric, but nitro cost big $$ per gallon, and electric cost mega $$$ in batteries, gas is only $8 for two gallons and the oil mix.

66: Yea I didn't go over half throttle the whole flight. The motor was idling high that is why the LG got a good testing lol. I got the idle down on the second and third flights and the landings where a lot better lol. The kinetic energy is very cool to mess with. I did a few tail slides on the third flight and it slid about 25 feet before it slowly flipped it was so cool to watch and I'll def get that on video next time.

 

AnyAir, bigger does fly better, doesn't it? Let's see...1/4 scale Patty Extra with a Fuji 43...fun sport/pattern plane. 1/3 scale Ohio R/C Extra 300L w/a Zenoah GT-74..fun patern bird. Soon, there will be a 1/3 scale H9 Sukhoi w/a DA100...all out 3d machine, I am sure...that motor and airframe tend to be referred to as WAY overpowered

But hey..I gotta admit, I have as much fun with a Vapor as anything else...heck, if it flies, I like it...from my airhogs stuff on up!!

That's the spirit! I know of a few guys who are missing so much fun because they thumb their noses at electric powered models of any kind.

 

iflyos: Thats what my screen name is all about Any Air Rc any thing that flies is cool with me! I am sure you'll love the H9 Sukhoi, I like how much work is already done for you.

 

What servos are you using for that plane?

 

I am using Hitec HS-645 MG ultra torque servos two for rudder two for elevator and two for ailerons. If you built anything larger I would upgrade the servos. That is part why I picked this size the servos cost a bunch more for 33% than they do for 25%.

 

I got a good idea, now, how much your plane cost. Just thinking about the future, thanks.
