Not enough Engine?
Meesh -
It all depends on your expectations. The Rascal is basically an RC free flight that is designed for sport and leisure flying - not 3D work. My Cub will do loops, rolls, stall turns, spins, and anything else a real Cub will do. If you want waterfalls, lomshevacs, knife edge, etc., get an Extra with a Moki 180 or similar. I replaced my 182Twin in my Sig Cap231ex with an Irvine 155 because the 2 stroke had more power and was considerably lighter. Fly your Rascal with the 130T, you will love it! Don't forget the plumbing mods and the on board glo!
By the way, I just ordered a 110 Rascal and will install my Enya 155 4stroke. Probably will never get above 1/2 throttle! Can't wait to fly it from my beach chair with a cool one handy!
