Hi Deebee
Short tail moments - have used it a lot. Given that you have to have enough tailplane area to compensate for the short moment arm, it works just fine. Not as pattern perfect as FAI aerobatics would demand, but fine for Sunday sports flying aerobaticificating.

If you really went for 'scale', getting in a bulkier control system than a bellcrank could be fun inducing Fitting a much larger fuel tank - otherwise often called a 'LiPo battery' - could be even more fun, especially with a mid-wing layout.

Joker - recall it vaguely from days gone by. Forget three channel, if you mean rudder/ele/throttle. It really demands ailerons and rudder, though you could get by with no rudder and hand toss/bellyflop for take-offs and landings. Put two very small servos, depending on model size, in the wings to waggle the ailerons. If still tight inside, consider a wing mounted RX, for another way out. 'Full size' could be real fun getting stuff inside.

But if you wanted an easy hobby, you'd buy an iSpendPhone
