I agree with the others here. I flew the SR60 for over 2 1/2 years and it was a great heli in it's day. Getting parts for it may be a problem and the stock heli needed some upgrades to keep it reliable. Finding these upgrades will be difficult. The 517's will not last much more that 4 gallons or so and I cannot recommend them even for a 30 class heli. They are fine in a trainer plank but the vibration and the loads a heli place on the servo's make them not so good. Start with a 30 and move on from there. If you get a 30 like the V2 Rappy you can upgrade it to a 50 later and save $$$ on parts and crashes.
