Visible Rotary Engine

I have built this kit two times in the last five years, and both times I got the same results!. First of all, this kit requires advanced modeling skills from a modeler that can work with extremely small electrical wiring and has allot of patience. second, the instructions say to lube all moving parts. Both times I built the kit no matter how well I lubed the moving parts with the recommended lube, the kits would work for about three months or so and then start to bind up inside. Also the stand for the engine is very thin and can be easily tipped due to the weight of the engine assembly. Also the light bulbs provided in the kit are to large for the openings provided. Luckily the proper size bulbs can be purchased at Hobby Lobby and fit very well. This kit will definitely exercise your modeling skills and results in a cheap looking model for the amount of money this kit costs.
