Ha, well you're getting better prices on the Fubs than I did then. The stock motor works ok, it just gets awfully hot if you venture beyond slow, smooth FF.

There are a lot of parts you can break- the usual suspects like shafts, flybar, gears, grips, skids and canopy. Then the secondary stuff- washout arms, flybar control frame, link ends, tail boom, frames, pushrods, ...you can go overboard here.
