Traxxas 4-Tec Conversion

[lincpimp]

I just finished modding the 2 speed to lock it up. Drilled and tapped a few holes, seems to run true. I am having the same issue as you with battery mounting. However I plan to run 5s, so I may just use some maxamps 2100 cells that I have laying around... A 5s 2100 20c (maybe) lipo will have around the power of a trakpower pack, so hopefully it will work. A 15l may be overkill, but hopefully it will stay cool... Same think with the 9920...

I managed to get the old rcm revo mount to fit the 4-tec chassis... Might even try the tekno mount, although I would like to have some adjustability for gearing. I plan to try a 20/45 to start. Should do around 60 with that. I will get some pics in a thread later...

Here is a snapshot of the chassis layout showing the plans. I tried to get a shot of the ruler to show how much room there is for the motor, but there was too much of a glare.

Sorry about the picture quality, it was taken via my cell...

Looks good Brian. I like how you re-mounted the servo. Must be tight for the linkage going under the front upper deck.

I got the motor mount in and put the center belt back on on mine. Looks like I have enough room to run 6s 2100 maxamps lipos, and I have that many "matched" cells (or at least what maxamps calls matched) so I may have to swap in a quark and give it a try. I will stick to a 5s pack at the moment, and see how it does. 5s and 20/41 gearing give me around 65mph, so we will see how this turd holds up to that.
