Mods/admins have preferential treatment.
Actually, I was talking to him today and he was gonna get one of these vehicles so he could develop a mount anyway. So, my vehicle is going to be for the greater good!
I just did more playing around with the center diff spur. It measures exactly 44.44mm in diameter, and has 48 teeth. That does not match either Mod1 nor 32p, but is somewhere in between. After doing a little calculation, the pitch is actually 28.578p, or Mod 0.889. I knew it didn't look right.!Both 32p and Mod1 gears roll somewhat smoothly without skipping, but don't mesh perfectly.
BTW, the formula for finding the pitch is:
pitch = (tooth_count+2) / (gear_diameter/25.4)
module = 25.4/pitch
So, Losi decided to really do some weird stuff here with the gears. The easiest thing to do would be to convert to Mod1 or 32p. But as I said, the diff has to be flipped around, which means the diff has to be raised to clear the chassis. To minimize the amount of height increase of the CD, a Revo 40T spur could be used, which is 42mm in diameter. This knocks off 1mm from the radius of the stock spur, which means it will fit without raising the CD much. And the 40T spur with a 12T pinion, along with the 4.41" tires, creates a speed of 30mph@30k rpm. Yeah, a little slow for some, but increasing the pinion to 14T creates a 35mph speed while not gearing up too high. And/or get a motor/voltage combo to get 35k rpm and the 12T pinion gets you 35mph. 14T would get you a little over 40mph.
