Have a Saito 100 in U Can Do, it flies great but when I do hovering for more than 30 to 45 seconds I lose engine power to the point that I have to stop hovering or I won't have enough power to pull out anymore. I think the engine is getting too warm, I have richened the high speed needle and will open the cowl more although it is fairly open, just wondering if this is a normal problem?
I am using exhaust pressure and a 15 X 4 prop. and 15% nitro fuel, the plane will climb out of sight if the throttle is open I only lose power in hover but I would like to be able to hover for a longer period of time.
