Ok folks, I have a serious ?. Tonight, I was doing the after run procedures spun the flywheel & noticed it was catching on the top end. Did the same thing when I spun the fw in the other direction. What is your take on these issue? thx in advance.
 
That's the "pinch". Nitro engines have tapered sleeves instead of piston rings.....That pinch is a sign of a good engine.
 
Great, thx guys. I have another ? tho, Sorry !!! . Truck runs fine & has great take off on first till 5-6 rounds of WOT. Why is the engine like slow on take off after it reaches 200 or hotter deg temp, it's great on WOT & on Idle. Model battery is fully charged, steering,trotle & brake servos has strong responce. Carb wide open on WOT &, a strong braking when applied, Blue smoke also looks good on WOT. Not sure what I'm missing, could anyone pls help? thx again in advance guys.
 
Keep richening until you know it's too rich, then lean it back to max power very slowly.
Then make sure your temp reading device is reading properly. Some of them have settings for reading different materials.
Is it cold out?

2r1m, It was on the high 70's & low 80's yesterday when I ran, & some humid.
should I start on the HSN to adjust or LSN? I I did not want to mess with the settings its only because, It was Idling so perfect, but If need to be tuned I can careless about the perfect Idling engine. Hope I'm making sense on these, thx again bud. ( PS. not much of a smoke when the engine is Idling, only when I punch the gas, then more smokes comes out.)
 
2r1m, I found out why the model is doing those stluff I've mentioned above. The Servo for Trottle & Brake "SLOWLY MOVES" when applying gas or brake, It only happens after 2-3 tanks. I heard chirping on the model after a week from out of the box, & did not know it was the servo doing the chirping sound. Now, I can hear the servo realy good, specialy when applying gas or brake. Should I replace the servo, what is your recomendation? thx in advance.
 
The battery is ok, charged it every time after each run. I even have a volt meter to test AC/DC.
I wish I knew how to post video, so I can post all my questions with vids. Thx again 2m1r, I will keep you & everyone posted.
 
Pull the servo horn and see how the servo sounds with no load. I'd also pull the servo apart and check the gears and make sure it all looks good.
