Doing a Brushless Conversion. Advice Please.

[spiftacu1ar]

Ok, I got my gearbox, and there were some hickups with assembly, but I have sorted most of them out now.

Here are some pics of it: http://picasaweb.google.com/sutyen/B...eat=directlink


So, there is not enough room for the stock plastic spur gear, so I was wondering how much thinner the steel spur is compared to the plastic one. If it is about 1/8th thinner, i am for sure fine, and 1/16th thinner I might be ok.

Also, what gearing do you all reccomend. THe gearbox has internal gearing of about 2.5:1 I would like to use a 47t spur if possible, as that will fit the best, and have the least interference with the chassis. HOwever, becasue of the gearbox design, the smallest pinon available with that spur is 15t. I can go bigger than 15t, but not smaller. 47:15 a good spur:pinion ratio for this gearbox/motor? (2200kv mamba monster combo)

Thanks for any help in advance.
