Hi all,

Have been reading on RCU for Quite a while now but never chimed in until now. I found all the info here Quite usefull and interesting. As this is my first post I will try to do it right. so here goes.
I recently found an old weedeater in the back yard that was given to my son. It was burried under a bunch of old bicycle and motorcycle stuff. Turns out it still ran.(it was there for years) It was a Homelite 31cc trimmer. Just the ticket for a first conversion attempt. I sent the flywheel to RS engines to be Machined,ordered their conversion kit, and went to work on the case. And Here are the Results:

Final Weight with Prop came in right at 4.5# , this is with muffler, V-Stack, and aluminum saftey spinner nut.

Fuel used was 91 octane, with 100-1 Amsoil Mix

RPM Results.......TopFlight 20x10 Power Point.......5400rpm
(was kind of dissapointed)

MA Classic 18x10 wide blade ......6400rpm (getting better)

and my final test today......15x8 Power Point........ 9400 rpm (just a test but WOW)

Next test will be with a 16x8 or 16x10 apc or MA Classic.

Final Cost with the two new big props. $110.00

Not to shabby for my first attempt. Going to put this engine on a Dynaflight FlyBaby, 84 in. wing span. Havent built it yet, but probably will over the summer.
