A few notes from my build. The motor plate hole is too small for a
24 pinion. A round file fixes that issue. The left front chassis brace
won't allow a brushless motor, no room to solder the ESC wires. Left
that brace off. The stock plastic shocks use a 28 mm shock shaft. If you
are trying to use the short option shocks, they are not long enough.
You can use the long shafts from the kit, or use the front M-07 shock tower
on the rear, and for the front, I modified the M-05R rear graphite shock
tower for use on the front of the MO-7. In both cases, the shock tower's ball stud holes are about 2mm lower than the stock M-07's. Also the after market non-Tamiya 35 and 33 spur gears are a perfect fit. Although you don't have to split the chassis to work on the gears, You still have to disassemble the front of the car. The kit diff oil is not labeled but in the directions it indicates 100,000K. In any case, I used 30,000K. We will see how it runs next week.
