This looked like a very promising nice little quadcopter. Neatly built, coming with original FlySky radio, and not a stripped version without display, like on the P175 and P200. But it seems very underpowered, and when trying to make fast turns, like you want to do with a racer, it drops down a rear corner on the inside of the turn. Maybe it needs some tuning, though the current flaws are unlikely to be possible to fix with better settings. To be continued...
