Ok, I tried adjusting the throttle agiain and no luck. I let the engine cool down and then adjusted throttle. I did this for about 2 tanks of gas which was about 2 hours of time.

Some background...The first 2 1/2 gallons of gas this heli flew like a dream...the last 1/2 gallon is when the problem developed and worsened. I then switched from 20% Cool Heli to 15% Byron to see if it was bad fuel. I have used the Byron in this heli before with good results.

I only adjusted the high speed needle valve. I assume the low speed adj does not need adj as it idles beutifully...or I could be wrong? At full throttle for 3 second this heli looses all power.

PS: It might be smart for me to buy a infrared temp gun. I will go to Lowes today to scout one out. A good operating temp for a OS32 is 190 F at hover throttle???

Thanks in advanced agiain!!!
