Most guys start off in the Basic class with a 50cc size plane, but the 107" plane will be easier to fly and present to the judges much better. Just be sure not to skimp on the servos and electronics in the plane. I would recomend 5 cell/6volt batteries or li-po (with 6volt regulators) for power. Also good, high torque, digital servos on all the surfaces, including the throtle. Practice, Practice, Practice!!!
Get a GOOD coach to help with flying the manuvers. You will be confident that you are flying the manuvers correctly, and you will also know thw routine backwards & forwards. Did I mention PRACTICE??. Good luck!!!
How did you like the Magic Hand ARF? I have an Extra 260 from Troybuilt and I haven't had a plane that was easier to assemble. This Extra has no pitch or coupling AT ALL. Makes me look good.
If you can handle the extra cost of the bigger plane, you will not be dissappointed. Your set-up will take you from Basic all the way to Unlimited class.
Bigger Flys Better.
