Well, 10 years of IC with this model was good enough for me, time to progress! After selling the full IC set up, bought me brand new 6Kwatt power horse. 200+ lipos of every size and capacity gives me great selection for enjoyable flight time with this model.
Just received the new larger prop I have tested today, 25x8 with rather nice performance after the quick static test. 15.75 kilogram pull @ some 6.7K/RPM. The ESC felt hardly any warmth, with motor reaching 50 C after loading it up to simulate short flight.
Rather impressive figures compare to the 23x8 I have used last 5 flights at 12.2 kilo static pull, where both the motor and ESC never even warmed up after 5 min. flight time and some 2350 mA consumed from 12S/5200/60C packs. I like it.
