alright. this is the issue. the jrsc has been making this noise about 3 months ago.

you guys know that the jsrc is made of blades right? so everytime i floor it and going pass 6k rpm, thats when it sounds like the blades are scratching along the sidewall of the jsrc.

how can i fix it? anyone ever had this problem?

 

Call JR, tell them the symptoms, let them advise you on THEIR product.

 

okay.

makes me think....like "why didnt i think of that earlier" duh..
