I've had a couple of these...wasn't real impressed with either.
For what you are going to pay for it why not buy an Enya SS .50 Ring ($125). It takes a while to break it in with it being ringed, but once that is done you have a VERY user friendly engine with gobs of power for it's size...topping that off it is quite LIGHT for a .50 BB engine. ANY Enya engine typically lasts FAR longer than an OS, K&B, TT, Magnum, etc., in the hands of a knowledgable modeler.
It's your money...spend it how you wonna![:-]
...don't blame me down the road...I told you so
