RE: Sig Li'l Rascal wing modification
Since I had bought two rascals (ok...I am a sucker for a pretty plane!) I decided to try a little experiment.
The main problem with this plane is tip stalls. It's easy to see why. The smaller wing on this mini-version provides marginal lift, and the wing tips don't contribute very much at all in lift or stability. Hence...the tip stalls.
So....
I added some 20% wing area to the plane, and it did make a difference. More stable...rises off the ground better and the landings are slightly less "dramatic" than with the stock wing.
The stock prop just does not have the thrust...so I'm using a GWS slow flyer prop. Works much better. Battery is a 11.v volt li poly. The motor may or may not last long with that battery...but it will cruise at 50% throttle...so that's not a lot of voltage.
See the pictures...
