I have the Eflite Ulitmate, 400park Eflite brushless(major powerhouse) with a 10x4.7 it turns to hard but keeps the motor cool,,, GWS flight pack, Phoenix 25 amp ESC, and using Electrifly 1500mah 11.1v Lipo,, I love the plane, I have hovered/Torque rolled everything from a UCANDO .46 to a Carden 40% and I must say that this thing is very quick, I mean that you have to be quick on the sticks to hold the fast torque roll I can do it now about a foot off the ground with no problem but it took a bunch of practice and stick time on this plane,, is a good flying plane,, would I buy another,, maybe,,, I am wanting one of Chip Hyde's Bipe's either the new Fore-Play or the Raptor3d, not because they might fly better(they might but I don't know havent' heard any flight reports) but just for a change of looks,,,,,
