Once the summer hits hopefully I can get a real mount made from a machinist and a plastic or graphite chassis.

I have a video now, the truck is very light in my hands, way lighter than when it was nitro and way lighter than my 1/8 buggy. I can feel like lightness in the truck through turns and accelerating. I think this truck will have a few ememy's at my local track. I can't wait to take the thing to the track and see how it flies compared to when it was stock and against other 1/10 trucks if racers let me wheel them for a pack or two.

I have a update.

I finally drove the truck with a fixed diff with 24/87 gearing and it is great. It has plenty of steering and rear traction, sort of like a XXX-BK2 compared to a CR. I just have to get a servo horn for my 94357 and put the MG-645 in my tool box as a back-up. I can't wait to try out the new servo and race it.

you may want to put the ball stud on the underside of that servo horn. that way the linkage wouldn't be at such and extreme angle.

How did you get the servo to mount that close to the steering without any binding?

The mount is a Tamiya F-103 formula 1/ Indy car steering setup. The truck is just completed and I'm waiting for good weather to test it. Moving it by hand doesn't seem to be a problem, although the ackerman is pretty wild. Don

Is that a servo horn with a built in servo saver? It looks like direct steering with no rack or anything.

Yes, it's a large Kimbrough I believe. Traxxas does something similar with some of their trucks. The servo is a FP-S9102. I had a 3003 in there, but when I went to the 4s A123 pack I needed more room. Don

I might have to try that, my old Traxxas has that setup. Is the servo you have now any smaller than a 94357 by any chance? How does it handle with no rack and what not.

It's a low profile wing servo, 1.76x.89x1.02. Torque is 50oz/in. Weight is 1.62 oz. I'm hoping handling will be good. All up weight of the truck is 66oz. I'm hoping my particular combination of brushless motor and battery will result in an electric truck that will easily run with it's gas counterparts. The motor is a Feigao 13t 380c with a KV of 3125. The battery pack is good for 13.2 volts. That works out to a potential 41k rpm, with I hope about half the current draw of a low turn 6.6-7.2 volt system. Don

Really nice setup but 50oz of torque isn't going to do much. Have you thought about the KO low-profile servo?
