BUY THE ARROW!!!! I have flown my fair share of airplanes helping my buddies learn to fly and I love the Arrow. It is really one of the best all around trainer/ aerobatic planes you can buy. It is rock solid and easy to fly and can be pushed really hard when you want to. A buddy of mine recently changed his motor in his arrow to a TT Pro .46 and that thing was a missile! Didn't last long as he decided to eat the tail off my SPAD and crash both our planes!

Good luck man and don't underestimate the diificulty of R/C. I fly full scale planes as part of my Comercial pilot training and it takes far more hand eye coordination to Fly an R/C aircraft than a real one. I also have hundreds of hours in Simulation time on Microsoft Flight Sim and I can still fly that one better than the R/C sims.

Edit: BTW Flying Tiger I love your plane. The look and sound of the 4 stroke just never gets old to me. They make any plane look cool.
