Thanks for the info. I'll contact Associated. The other idea sounds good too.
Also, does anyone know if LRP sells the low profile OR regular Sphere flat heatsink? I could only locate the upgrade world's kit. Has anyone ever done it the otherway?
I realize now that I only need the regular sphere since I race only 13.5 and 10.5 motors for off-road. Also, carpet season is starting and the Sphere is pretty small w/o the heatsink.
Thanks again.
