gearing tip for 8xl ?

[spaz163]

I emailed Mike when I was looking to buy a pinion for my Ofna MBX buggy conversion. I am running a 8XL on 14 cells and suggested starting with either a 14 or 15 tooth pinion. I went with the 15 and it does indeed move out, might actually be alittle too quick but that will change with where ever you are driving the rig.

I have no experience with either of those controllers so I can't help you there.

20 to 30 minutes runtime is quite long, you may need something up around 8000 MaH to pull those times off. Just make sure that you have a charger that will put out enough amperage so that it doesn't take several hours to charge one pack. I believe you should stick around 1C for Lipo charging which on an 8000 pack is 8A.
