Today I fired up the 1st Ielasi Tuned 9cl engine. This one did run for 4 hours in the oil bath and I was amazed how easy it did start (after a pre-heat). When hitting the throttle the engine did not show any signs of a tight fit. Did run 1 tank with a slight rich setting and the 2nd tank was straigh on a sharp tuning without any issues.

Yes, this is the future!
