Just found a way to test the firewall integrity and the wing and H. stabilizer soundness with the mods mentioned here.....
A brand new .76 Sport Jett engine
Gosh, what an engine! This thing actually scares me. It seems to have more horsepower than my lawn mower. It'll turn a 12-6 prop at 14,300, or more.
Took her out to the field yesterday to try it, but it rained. Nuts.
Will try again and report back on if this plane can take it!...
