I have a 25 in a Great planes Space walker. and it is great. I just picked up a hangar 9 messerschmitt 109 I was thinking of putting in a Homelite 25 in that do to having to add so much to the nose to get the CG. Not sure on how it will fit in the cow yet. Making my own engines is the best way to go. but with some planes mite not be a so bad to go with something like the DLE. but if the power to price is worth it.. Just trying to come up with a plan. Thanks for the info.
