The frame itself is pretty decent, it appears to be full carbon fiber with smooth edges.
The screws are of good quality they don't round out or strip like some Chinese screws do. The bearings and block so far have been decent, I will update to Al*gn bearings. The tail gear setup however is a very poor design. The gear that the belt fits on is not centered in the boom it's too close to the top, also there are some plastic notches that stick out on each side of the boom holder to guide the belt I assume. They rub the belt and cut into it causing major vibration and the boom gets warm/hot from the belt rubbing. You could try and drive the belt gear down to center more on the shaft and cut the notches out of the boom block, but I just ordered all Al*gn TT setup, tired of dealing with this. The drive gear that meets the auto rotation gear for the tail is also warped . Good for frame parts but throw the tail stuff in the can!
