I did state that he should bench run them first to see what he has.
I have own those engines several years now(flyed 1:12 aircombat a few years with em) and I know what I have, but thanks anyway about the information and tips what I should think when building a twinner. Robert Kozak: I think you have managed to build good and powerful engine. I havent had any major problems with em and alot of pilots uses MVVS .21 power plants in combat here in Finland. This is getting a bit out of the subject.
I sitll would be grateful if someone has a drawings to .21 size twinner. :stupid:
