Has anyone used flapperons on the Rascal 40 ARF? Since there are two aileron servos, it should be an easy thing to do with a computer radio. Probably isn't "necessary" but might be interesting.

Engine selection - I know that quite a few people are using small four strokes on this thing but my budget doesn't permit. I was thinking about a Thunder Tiger 46. I assume that a 60-size 2S would be too much! Other recommendations?

I won this ARF as a door prize at a local fun fly and I am looking forward to getting it in the air!!

If you increase the aileron's chord (front to back) by two to two and a half times, you will find that flaperons are most effective.

If you do not, you will see a decrease in roll rate performance and a barely discernable difference when flaps are deployed.

I just finished a Rascal 40 and it is a screamer with an OS 46FX! I usually end up flying it at half throttle or less-it runs a looooong time on the gas tank included with the kit. I'm running it with an 11X7 prop.

Congratulations Ross on your door prize windfall.
My first Rascal had a TT46Pro motor and was a real screamer. More than enough power, and very economical in all respects.
When I was assembling that model, I had the opportunity to test fit a .60 2S and found it too large to install without unaceptable alterations to the fusalage. In any event, the TT46 was more than adequate for power and speed.
At the time I owned that plane, I did not have the option of flaperons, and found it hard to slow the speed down enough for short landings. The Rascal has a long glide ratio even at engine idle, and wants to keep on flying and flying and flying.
After the untimely demise of that model, I have replaced it with an identical example, but this time substituted a Saito .56 motor, and a transmitter with flaperon and airbrake functions. With the addition of a Bolle 3 blade 11.25 X 6.5 prop, the Rascal can park itself on a postage stamp. (A real big postage stamp with grass growing on it.)
The installation of a Nelson intelligent glo driver has made starting the engine very easy, and allows for a slow and stable idle. The Rascal can accomodate a substantial payload without detrimental effect on performance, and the extra weight of an onboard glo driver seems justifiable considering the advantages of this device. (IMO)
I hope you enjoy yours as much as I am enjoying mine.

Now that I've flown my Rascal 40 a bit more, I've learned how to do a very important maneuver-the slip
