Hi all, im looking for some advice for moving IC engines from RC cars to RC planes. I dont know if this can be done or if it should be, but it seems a shame for the engines to be sitting idle in cars I no longer use. I spoke to someone and they said that it depends if you can get your down and side thurst right and that you probably have to change your cylinder head. Do the engines vary that much?, I have a irvine 20 engine that starts with a spinner/pully system, would this not have the same characteristics as an aero engine. Any help or advice would be greatly appreciated and if it shouldent be done please tell me and the reasons why. Thanks all.
