I totally agree with Tim. I have a 250, 450, 500 and 600 size. The 600 being Nitro. It is definitely more stable, less susceptible to wind, etc. BUT crashing is significantly more expensive. However it is also much easier to work on. If I had it to do all over again. The 500 size electric is a good compromise. Not too scary, not too expensive. Batteries are much cheaper, and very stable. Much bigger than a 450 size. When you guys fly again, I'll bring some of mine too. Got a new toy for the 450.........
