No worries, I know there are many other engines better suited to performance mods etc but this is what I have to experiment with right now. Plus it's a direct upgrade to a plane I've flown a lot with the 20 engine. If I wanted to put a lot of power in this Mustang I would have dropped in an OS or BVM 91 DF engine for ultimate power to weight ratio!

Im redoing the radio and tank installation so it's going to take a little time for the engine run report.

Last time I ran the 20 I remember the tach reading about 8500 with an APC 16x10. I'm going to use the same, new, prop to have a comparison with the RA.

If you guys have DLE Mod or improvement info please post it here.
