The original idea was to just have a large Twin electric trainer but now I'm thinking seriously of taking about half of the dihedral out of it so that it'd be more aerobatic. Also every plane I've ever had was a tail dragger so the tricycle gear is for some experience also.

Edit; I shouldn't have bragged about the Twin SS in post #7

Wish I'd of had a steerable nose wheel on my Twin Simple Stick today instead of the tail drag . The 4th flight it suddenly took a left turn on take off before I had good airspeed for rudder control and hit a curb which resulted in it going airborne for a short distance and... well I have quite a bit of repairs to do now. Then I lost my E-Flite Ultimate in the sun on landing and totaled it. Not a good afternoon/evening for my planes today but I have a few more Ultimates almost ready to go and it'll only take a couple of hours to fix the Twin SS.
Back to the Twin ST-40, how much larger should I go for the single stab/rudder over the stock unit? I know what I'd do for the twin stabs/rudders but not for a single unit.

Thanks &
Merry Christmas,
