R/C Tech Forums - Tamiya mini cooper

a picture is worth a thousand words.. during my build I had issue with getting R1-wurks motor to fit with 20t pinion.

I'm guessing each motor could have unique issues.

No room for tabs to rotate rearward (right in picture) to fit pinion bigger than 20t. When fitting the 20t pinion the tab shown is pressed hard against the chassis. Can also see where the can portion still has room to move rearward.

Time to get the Dremel out. should only require minimal material removal for this issue..

Using the HW style can, I had to rotate the motor fairly far clockwise to get the wires to clear the reinforcement. This led to interference with the side of the tub (circled in red). Filed a teensy bit off of there, just so the wires weren't under constant strain. Don't really want to shave anything from the reinforcing piece. Pretty sure if I had a 3D printer, I'd design a replacement part.

Does anyone know the part number for the "big bore" shock pistons? Same as the TRF419X maybe?

What body are you guys going to use for your MO-7s?

Might use my protoform SoCal panel wagons.

How long did it take to build your M07? Less long than it took to build the M05? Going to order one through RCmart.

V2R manual says 53573. Tamiya really doesn't make it easy to find out which pistons are compatible with which bodies in case we want to try something other than the original 3 hole :rolleyes:

Found it. It's listed in the manual for the TB Evo.6 MS...blah, blah, blah. The 05 v2 R appears to use a short TRF damper, but not the big bore version. It's p/n 19804876.

Huh. You're not wrong. I've always thought the R spec shocks were big bores, but nope, I just measured them against the 42291 big bores. Outer dimensions appear identical, but the inner bore is 0.5mm narrower on the R spec. I guess that explains why the standard ones have a smooth edge around the top collar and the big bores have the knurled edge.
