I had both units for a few months. There are several revisions of both units. The rctimer I had was using stiffer plastic and was vibrating much less than the V2 S800. The soldering was bad and it was using thinner wire in the arms but I did not notice any performance issues because of it. The center plates were a 100% copy of DJI original. The rctimer landing gear was of lower build quality. The rctimer frame was a better performer due to the fast switching simonk esc's.
All in all two pieces of plastic junk. The clone is better though.
