What kind of run can I expect from this engine? And is a 10-6 the prop to use? APC,MAS or wood? Was planning on 10-22 fuel 50/50   Thanks

You literaly have a tiger by the tail with that engine, it's a screemer but lots of fun on a Flight Streak. It's basically a combat engine designed to run flat out on 20% nitro. You will be fine with 10-22 but expect to be running 75 or 80 MPH.

    Oh, maybe, depending on the particular model  - I have seen at least 4 different engines that were nominally G21-35s). But I flew mine with 5% nitro in a 4-2 break with more-or-less acceptable results for my skill level at the time. It's certainly not an ideal stunt motor, and it's trivially easy and cheap to get a better  motor, but if you have one it's not impossible.


       I recall that I ran an Rev-Up 11-5 with the stock venturi and *no muffler*, which ought to date it pretty well. Certainly has more ponies on tap than a Fox 35, which was my basis for comparison at the time.

     Alternately, you could sell it on eBay and then use the proceeds to buy 3 46LAs or Magnum 36's, but that's a different issue.
