I just bought a Moki 1.80 and have only praise for this awesome engine. All I did was read up on it in RCU, bought one, read the manual, and ran a gallon through it. I put a Cline reg on it and ran a few tanks to test it and it ran great. I put it on my 25% Kangke CAP232 and have flown about 20 flights on it (just over a gallon). Prop hanging, harriers, knife edges, blenders...not a single flame out running 5% nitro, 20% oil, and a type F plug. I use a Bambula 18-8 prop. I love this engine. Just follow the manual and your odds of success are almost guranteed. Yes there are always bad ones but my 1st one was a darn good one.

BTW, if your going to prop hang, run it plenty rich to keep it cool, especially if it's newer.
