I had lots of engine degrading problems just flying around for short periods of time (less than 30 minutes). I thought I was missing something but reading this post reassures my belief.
I also experienced that the MW-50 inst increasing the performance of the plane, seems to be broken?
-If I fly at sea level, leveled in straight line, with or without MW-50, I get the same speed, even MW-50 seems to worsen it by a tiny bit.
I was wrong, not truth, without MW-50 I get 550 km/h, with MW50 600 km/h.
If I dare to touch the radiator flaps, my oil temps rises beyond 130 and the engine is destroyed after 2 or 3 minutes, but that is just my fault I guess, I gotta read the manual regarding Oil temp management.
