Ax10 Based crawler project

[lincpimp]

So I have about finished gathering parts for my 2.2 crawler build. Going to use ax10 axles, pede tranny, sidewinder, and an outrunner.

Have the axles and the tranny built. Chassis will be based on the gatekeeper design. I will use revo pushrods for the links, and traxxas xl shocks, most likely with losi truck springs. Chassis material will be kydex, and I have some axial stand-offs to use with that. I have the gatekeeper lower skid for the pede tranny.

Plan to run a 833kv outrunner I have on 3s lipo with the sidewinder. I have a jr ds8711 servo and will feed it with a ccbec, as the sidewinder bec is a bit weak.

Link to the motor: http://cgi.ebay.com/RC-Airplane-Mode...QQcmdZViewItem

Due to the 5mm shaft, I will be using 32p gearing. I have a friend with an ax10 that runs a novak 55t motor on 3s, and with stock gearing it does about 5mph, so has decent wheel speed. 60/18 gearing with the 833kv motor on 3s will give me similar speed, and hopefully more torque than a brushed motor.

I may step up to 4s lipo, and gear it down more. Depends on how well it starts with the current gearing. I basically do not want any cogging. Any ideas what esc settings I should run? I am guessing high timing and high start power, as it is an outrunner? No punch control, of course, and quite a bit of drag brake.

I will have some pics of the parts tomorrow, and hopefully I will have time to cut the sideplates and servo mounts.

Why not use an Axial tranny? The size and fact that they're already locked makes them much more desirable than a pede tranny IMO.

I have to claim cheapness as my main reason. I already have the pede tranny, so it is $0 vs $40 for the axial. I also have the skidplate too, so it is $0 vs $20 for that. And I have the materials and template to make the side plates and servo mounts so it is $0 vs $100 for the kit (which would include the skid, but you get the point). I also have all of the electronics, so it has cost about $150 to get the axles and the other various parts I did not have. So it was pretty cheap to do this build...

Makes sense. If you need any other parts for it, let me know. I have a bunch of Axial parts at the house.

Sweet, I will definately do that. I will take some pics of the various parts I have so far. Should be an easy build, at least I hope so...

70mm from center eye to center eye on the ends? Or a 70mm tube? I have some of the stock cross tubes and stock upper link tube from an ARTR thst should be real close to 70mm with a Traxxas rod end on them.
