My Engine Lost RPM

[TRAMTRAN]

My friends, this is what’s happened to my helicopter.

30% nitro fuel
Align Glass Fiber Blade, Grade A
Youngblood Governor - 1950 RPM idl1 and above 2000 RMP idl2
Pitch +-13

I checked the tracking and it’s was fine at the tip but in the middle of the blade It’s not perfectly on track it’s kind of blurry when I look at it. No vibration. When I do tick toc It’s lost RPM. When I do fast flip, I have to let the engine a break for about 10 second in order for me to do the fourth flip. Is this normal in T rex 600 nitro?

Too much pitch probably, how much cyclic are you running?

Sounds like you are bogging the motor, have to lighten up your touch from the sound of it.

I would agree...

I have been flying Heli for only 3 months, and I had about 40 flights real life experience. I can pilot a lot better than I can set up. I can do backward inverted, Chaos, Piro Loops, Tic Tocs and death spiral without any problems. But I do have problem with terminology with this hobby. Please help my out.

what do you mean when you say lighten up your touch?
What’s is ciclic ? I know how to check my pitch with pitch gauge, tracking issue, that’s all I know.

[TRAMTRAN]

ciclic I mean Cyclic

[invertmast]

dont use so much pitch during the manuevers. using to much pitch causes the engine to bog

TRAMTRAN , how many gallons of fuel have you run thru the motor since it was new? it may be time for a rebuild of the motor , try replacing the ring and bearings....

[TRAMTRAN]

I had about 2 gallon on this motor. I think the problem could be the glass fiber blade and high pitch. I just ordered a pair of youngblood blade, and I will set my pitch to +-11 and hope will fix the problem this weekend.

Thanks

maybe you're running your engine too rich. after flying, land it and put your finger on the backplate, if its cold then you're too rich... lean it out a little. You should be able to hold your hand there for 5 or 6 seconds before it gettin too hot.
