I am in the last stages of breaking in my new Team Losi GTX and doing a few WOT runs. When it gets to a higher speed, it bogs down. What adjustments do I need to make in my needles for bogging down at WOT?

When I turned it off, i realized the air filter fell off at one point. I don't know if this was before or after I noticed the bogging so I don't konw if that would make any difference.

i say richen the hsn a 1/8 to 1/4 turn

I forgot to mention that I was running at about 230 degrees. I'll richen it a bit next time I run it and see if that helps with the bogging.

Question about the LSN now: the motor is a .12. I figured in the gravel the rear tires would be spinning and I could turn some donuts but nope. I'm thinking I need to lean out the LSN a bit. It does spit out quite a bit of blue smoke when accelerating. Or does this motor just not have enough power to turn donuts in the gravel?

Tune your HSN first. After it is running good and fast start tuning the LSN by the pinch test. Then you shuould be spinning dounuts like mad!
