Moki 30 hd vs mark g180
The Moki 30HD is a 30cc gas motor and the Mark/ Moki G180 is 30cc and a gas motor. One is front induction and the other is rear induction.
Mark Engines (Powered by Hungarian-Moki), made in Hungary, has provided only the best-quality miniature aircraft engines since 1957. Recognized the world-over for their high-performance and beautiful machining, Mark Engines has established themselves as a fine model engine maker.
My question is ; what would be the deciding factor of one motor over the other? The only thing I can see if you needed more nose weight you would go with the 30HD do to it weights 51oz vs 42oz. Both will turn a 20/8 or 10 prop. Both or good for 10,500 rpm @3.9hp.

I would be more prone to go with the 30HD over the G180 given identical performance specs. The G180 is a converted nitro engine and is a rotary valve induction with the carb mounted ahead of the cylinder. The 30HD was designed as a gas engine with a rear mounted carb. From the pictures, it appears to be a reed valve induction.
The deciding factor, in my own mind and excluding the weight factor would be the possible longevity of the engine is the case of an uncontrolled landing (crash is a dirty word). The possibility of damage to the crab and/or the carb mount appears to be more of a problem with the G180.
