Run of my newly aquired TD .051

balogh wrote:Great run, TD Bandit, I tached with my smartphone app 16,3k before it stopped. I usually start the run-in process at an even lower rpm when the engine runs like a four-stroke because of the rich fuel. The rich fuel will not only keep the engine cooler but will, I guess, prevent that too "large" chunks of surface unevennesses are sheared off from the mating surfaces before the piston and cylinder materuial metallurgically stabilizes during the initial runs. The result: excellent compression retained for a long time.

If you keep it clean, run it on all-castor and avoid leaning out, the beast will serve you for well over 200+hours. I just had my R/C plane out in the field after a rekitting and repair  some weeks ago, and the ole TD051 with hundreds of hours under its belt restarted at the first flip and revved around 24k in the air unloaded.

Enjoy the TD051 like I do..

I also have a number of New In Box engines whose balljoint is a bit sloppy, but thanks to the resetting tool one can easily mend it.Remember though that if you set it too tight, the ball will puncture the piston top in only a few minutes.

It may, however run on Flex Fuel as it has about 80% ethanol. Just thinking out loud, so to speak. I'll ask my son, he's a chemist, if it would sustain a run on gasoline without the battery, even with only 10% alky like we get at the pump today. That harsh combustion could have loosened the socket, especially with no castor.

Maybe it's just gasoline with methanol in it. Ethanol will catalyze, but not quite as efficiently as methanol. I just shot a long text asking my son Al, about the possibilities.
