I have the 1100mm/6s Prometheus in my garage! Only thing I don't like about it is the aluminum landing gear is really 'soft'. Prometheus is a freaking monster flying! Does everything Skip does in real life! I also had the beast. 2s isn't enuf. Needs a 3s, but esc can't handle it.
The roll rate on this thing looks even faster than the UMX Pitts! (And that is already too fast for me) If you are not able to repair that rudder, it looks like Horizon still have the replacement tail set in stock. EFLU5060. Looks like it should be as easy to swap out as the UMX Turbo Timber.
