I believe CMPANG hit it squarely on the head - Feng really needs to hire a competent manager to run his business so he can devote time to new product development & setting up a stronger system of quality & production control. Besides the constant delays which seem to affect everything coming out of their shop, its the lack of QC thats most troubling, whether its related to missing parts, poor molding - GRP hulls are supposed to be their specialty..., poor instructions, lack of drawings, etc.. can be found on almost every model boating forum.

Regarding your T-55, I'd start posting your concerns over at RCTANKHQ since they appear to be Hooben's head cheerleader at the moment.
