HIROBO LAMA ..OS37 UNNING HOT.

hi....could someone please advise ..i have a Hirobo Lama 30 ...fitted wth an OS37...ringed...i do find the engine runs a little hot due to poor air/flow..i have tried to run the engine very rich setting...what i was wondering would an ABC engine be a better coice?...i think these engines can withstand much more heat?...thanks.

RE: HIROBO LAMA ..OS37 UNNING HOT.

I have a 37 in a hirobo 30 sized huey and I run a high rotor head speed and also run it rich. Try this. Spinning the cooling fan a little faster seems to keep the little motor cool as a cucumber.
