This is the new mid motor conversion kit I'm working on for original Associated RC10s. The kit uses a new laydown 4-gear transmission case, a new bulkhead, a new rear tower, and a new motor plate. The conversion is 100% bolt-in, not a single hole needs to be drilled or no cutting of parts is needed. Once the kit is finalized the parts will all be made available to anyone who wants to build one.
The build thread of the conversion can be seen here http://www.rc10talk.com/viewtopic.php?f=35&t=40247&sid=2d7c89702c6fed6521e068a6bd89aeec
Unfortunately all the pictures in the thread were on photobucket and so they no longer show. I'll try to fix them later.
Track testing of the car is ongoing and so far it seems to handle great and be very durable. I'll see if I can get some video of the car on the track soon.
