MT50 NG?

Vess 22A 6850
BME 20 3DA 7000, it really performs with this prop in a 82" Extra at 15 pounds.

RCGF 100cc Chinese twin....Stock mufflers, 3W 26-10 prop...55 degrees F, 6800 feet ASL, OLD gas/oil..
6400 rpm..TNC tach.....Maybe 10 minutes on the engine, it could be loosened up some and get a little better....
The gas/oil has been in the test stand tank for at least 3 months, with Hayes molded neoprene fuel line submerged all the time...So much for urban myths about neoprene and stale fuel...

3W 157 CS TS with about 200 litres of fuel through it. 3W oil at 50:1
PEFA L90 cannisters, the long ones!

New gasket set in the carbie today and re-set the needles back to initial settings for a run in the backyard.

Mejlik 28.5-12 3 blade got me 5750 rpms with a hot engine and an idle of 1000 rpms.
Should be a little more in it when I tune it correctly, (I tune mine at the field by flying it) it will be rich for sure on the top end.

Just for kicks turn the snorkel around, use a longer piece of tubing to connect it...Check the rpms on the ground...
You might be surprised....
