Richmond RC and VMAR Engine Test Stand (Critical Failure)
I must disagree. I bought this stand a year ago and have broken in about 7-8 motors on it from 46 size to saito 150 size. The smaller engines I just hold the thing to a platform with clamps, The larger ones I screw in. For the money It has been great. Of course you allways need to be aware of screws coming loose due to vibration etc and you may have to add a bolt here or there but for 18 bucks it has served me very well. Personally I wouldnt put anything bigger than a 150 on it though. I also ran wood screws thru the bottoms of the wood engine supports for extra strength.
