HPI WR8 Flux Plastic / Delrin Spur Gear and Mod 1 or Mod .8
I am hoping somebody can point me in the right direction. I recently just purchased a HPI WR8 Flux, Ken Block. It runs a Steel Mod 1 46T Spur gear and a Steel Mod 1 15T Pinion.
I am interested in finding a Plastic or Delrin Spur to replace the Steel one, but because the steel one has a longer bearing retainer than other Spur gears, I haven't found a plastic or Delrin Spur Gear as of yet.
I would like to go plastic for several reasons, the primary being that the steel version is very loud, and puts unnecessary stress on the driveline in certain situations. I would rather loose a spur, than have it damage my motor shaft or other components.
Also, I strongly feel the WR8 Flux doesn't NEED a Steel Spur Gear... the WR8 weighs a little over 5lbs With a battery, and is running a Steel Mod 1 gear. I also own several Traxxas vehicles, such as the Slash 4x4 and Traxxas Rally 1/10, running 4-pole 550 motors. The Traxxas units run Plastic 32 Pitch or Mod .8 Spur gears without any problems at all. Per Traxxas, the Rally weighs 98 ounces without a battery... add a 300 gram 5000 mah battery and the weight is 6.75 pounds... and that is with STOCK electronics and 540 motor. The Traxxas is easily 1.5 to 2 pounds heavier than the HPI WR8 flux, and runs the plastic 32 pitch gears fine.
Have any of you owners (or people with the experience in the HPI WR8 Flux) with the WR8 found or used a plastic spur gear? Can you point me in the right direction or to a part number?
Going plastic or Delrin is my top priority... if I can go to a plastic 32 pitch, that is even better. On the WR8, the Spur gear acts as a lid to the Center Differential, and is attached with 4 screws, and on the other side is the longer bearing holder. The stock Spur Gear is 66654 (HPI66654).
I'm not trying to debate the pros-cons of a Steel Spur Gear or Mod 1 to 32 Pitch, but if you can help me locate a Plastic Spur gear (either mod 1 or Mod .8/32 pitch) that would work, I would really appreciate it.
