yes i know quite a bit about them,i had one in a conquest.it's called a rossi 53.it won't fit many helicopters because it has a different crankshaft on it.but if you can get it fit,it's a good engine.it's fussy about the type of tuned pipe fitted to it.i had a zimmerman 50 quiet pipe on it and it was awfull,it cut out on spool up every time, nightmare,but i changed the pipe to a novarossi 50 pipe and it was 100% cured almost,no more cutting out,and good power.it runs on any fuel you put in it,from 0-30% nitro.good high compression abc engines,oh and one last thing,the exhaust outlet is slightly different to the os one,the screw holes are closer together,you have to re drill the manifold if it's an os one.
