Today at the Flying field I think my OS 32 went south on me but, I need some input here.
Just for a little history, I have been fighting a heat issue with this engine for some time now. It always seem to run way to hot. I tried everything I've read hear and other places plus my own experience of over ten years of flying airplanes.

So, here's what happened. I flew one time for about 10 min and it flew ok, but as usual the engine got extremely hot, not to mention the temperature out side was 95 degrees. I let the heli sit and cool for around 20min then refueled it, started it, and set it out for a flight.
It spooled up fine but, when it got just past low hover the engine just lost all power, it did not die, but I nearly crashed because the engine didn't produce enough power to properly slow the heli. I landed the heli checked everything over, fired it back up and the same thing happened, it just wouldn't produce any power past a low hover.

Are these the signs of a "cooked " engine?
or
Should I look elsewhere?

DO you run a fuel filter on your heli? I had a bad fuel filter cause all kinds of problems including a very hot running engine! My heli was running at over 230 degrees, I took the fuel filter off and started it back up and it now runs at below 190 degrees. Make sure you also check all your gas lines and make sure that you don't have an air leak on the engine.

if it's a ringed engine, check the ring...

If their is little compression , in hot weather the cylinder will expand father than the ring can , giving not enough compression to produce power. Your ring may be to worn if so replace it and re-break in.

This is the ABC model.
I took it off the heli, and compression still feels very strong. No visible signs of damage or burns on piston or other signs of extreme heat. I will dis-assemble the carb and give it the once over.
The clutch liner, clutch, bearings, belt, gears, etc all feel and look fine.
In fact the clutch and clutch liner look and feel like new, the heli is a JR Venture CP, I've always heard that JR has a low clutch failure rate. This heli is on it's 7th gallon of fuel which by my calculations bring flight time to around 15hrs and the clutch and bearings look and feel as new.

Thanks for the help.

hey furyflyer,
last nite i put a post on this thread suggesting bigwave check his clutch, fan and bearing blocks for drag/slippage before pulling the engine, and it ain't there today. not that it's any big deal, just curious what happened.

never mind. he had the same question on another site. my mistake.

No problem
