The RMC "Type D" Non-Compression Engine - YouTube. Compared to other gas engine kits, this kit is fairly simple to machine since the engine doesnt have any gears, cams, push rods, valves, etc. Care should still be taken to machine the few parts this engine does have and a small lathe & mill & standard tools will be needed to machine the castings & make parts for this engine. The base & head were sand cast without a follow board using RMCs own handmade core-less patterns. Because the base casting on the Type D engine is so unique, it has a longer parting line than normal.Also like any casting, foundry finish quality can vary & depending on the foundry finish, it may take time to detail the castings as wanted. The castings are made from high-grade ductile iron & do clean up easily with an air die grinder, carbide burr & files. Note that the base casting has mounting bosses placed conveniently on it, making it ideal for free-lance engine builders to make an engine out of.
