Thanks for the info - there is a difference between the mount on the muffler for the four stroke, it has the round exhaust port. I planned on picking up a better front nose gear based off what I have been reading. I think I might have one sitting around??? We will see. It's nice to see that after a year there is still people flying this plane. Makes me feel better about the purchase. I've already been thinking of upgrades, but will probably only upgrade the nessecery items to get her flying.
