Fellows that are using these engines for stunt what N and oil mix are you using, I am thinking mostly syn, part castor (16% syn and 6% castor with 5% nitro), and long reach t/bolt plug, 10.5x4.5 A P C prop, wet two cycle at about 10,000 R P M..
How does this compare to your set up?
Thanks

I have a regular TT .36, so I'll be interested as well.

Bootleggers set up works fine. Fuel can be SIG Champion 10/10/10, I pour out 4 oz of fuel and add 4 oz of SIG Castor oil. Engine runs fine, doesn't overheat and holds needle just fine. I don't tach it, just set it so its just breaking in and out before launch. Rocket launch, after about a lap or so it settles down and stays that way through the flight. Little speed up burps at the end of tank, gives plenty of warning. I use a tongue muffler with 4 rows of 3/32" holes in it. Uniflow tank on suction only, no muffler pressure. Tried a commercial tube muffler and engine didn't want to settle down, my guess for what its worth is the motor likes a little back pressure, I think the extra Castor oil helps too.

Hi Gerald-
So that's 4 rows of how many holes, or how many total 3/32" holes exactly?
Thanks in advance.

If you want to know about the Aero Tiger there was one in a Vulcan in Oklahoma last week that was pretty dog gone good. I don't know if it could get any better than that one.
