I am with you on the gas engines. I dont mind the plug sticking out of the bottom of the cowl, it has to be cut some anyway for cooling. I really want a gas engine but the G38 will not fit b/c it is rear exhaust. ( I am assuming it wont fit) There is only 6" to play with from the firewall to the prop, so, most engines that have the carb or exhaust in the rear would be really tight, if it would work at all. The G62 would work but would be alot of weight,etc. But hey, this is the fun part of this hobby, researching and buying just the right motor,right?
