OK, this addresses the issue of remote igniter, but the issue of inverted engine from performance point of view and from gunking point of view remains. What do you guys do regarding the gunking? Is there some way to avoid it? As per the RC Magazine, OS recommends that AX series engine fuels need to have atleast some percentage of castor, so even if I move to 10% synthetic-10%castor mix, gunking will still occur. And will that inverted mounting hurt my engine in any way?
