Trx Pro .15 tuning
Ok so i pulled this rustler out again after not wanting to mess with it for so long becuase its tune is like finding a fish in the ocean. I put the hsn at 2.5, and the lsn flush, wouldnt start at all. So i turned the hsn out till it hit 3.5 turns out and it started and ran. Top end seemed ok, but was super sluggish takin off. So i leaned it out, wouldnt run, till i put it back to where i had it. I could move the lsn a little bit but it made no difference. Same with the hsn, if i moved it say 1/2 turn it wouldnt run. Am i doing something wrong. This is actually the only traxxas motor ive tuned, but i have no problem at all tuning any other motor ive tried, big and small block.

RE: Trx Pro .15 tuning
Get it back to factory settings. Run it hard even if it is sluggish for about 5 minutes. Then pinch the fuel line 1 inch from teh carb and count how many seconds it takes to stall. It should rev up slightly and die in about 4 seconds. Get your LSN until it does that. Then richen 1/8 of a turn and tune the HSN.
