First of all western flyer I would like to wecome you aboard here at RCU

Also the engines you listed like Jester suggested are all well worth saving as is the uncompleted Goldberg Eagle. There is one problem though, that is in my opinion as buzzard bait and ratshooter has hinted at is all those engines are just too big and heavy for that lovely little trainer. It will turn the airplane into a hotrod and certainly not the kind of airplane you want for a thirty year returnee. I too love the FP's but only have two and they will never leave my greedy paws, one on a small RC floatplane and the other on one of my controlline airplanes. I can tell you the FP, are definitely appreciated by the controlline crowd I forgot all the sizes of the FP's but at least four and up to .65. The .40 would be wonderful on the Eagle.
