Except for the fact that motor rotation direction has a dramatic affect on how the car drives.

^^^^^ Gooood point. That's a minor detail.

I was not originally talking about motor direction...

I just commented on why the motor was mounted on two different sides when it related to a 3 gear setup vs 4 gear setup...

My only comment about motor rotation was that the quoted individual in my post was right after they addressed me saying that a motor "could" be reverse on an ESC... Technically they are right, didn't say that it was the right way to do it

It would be a challenge to have enough room for the spur gear to clear the driveshafts, while also keeping the diff & shafts low enough in the chassis (not an excessively large diff gear). I've wondered if it might be possible for stock with the smaller spur gears used, but never tried to lay it out to see. Seriously doubt if it could work for modified.

I believe the reason is to keep the FINAL DRIVE RATIO correct without having to use larger gears which in turn would equal the same amount of rotating mass. I may be wrong just my thoughts.

Not necessarily. If you are talking about how the rotation will alter the pitch of the car, that is primarily due to the tires. The tires are the largest, and heaviest rotating object in the drivetrain. Their change in angular momentum is what pitches the car up and down. The motor rotation would slightly affect this pitch, but is negligible compared to the tires/wheels.

I was answering the question but not in proper context. Even though we were talking about the MIP tranny my bad.

The motor is spinning considerably faster which comes into play. Not saying the 2 driven tires aren't significant, they are, but so is the motor.

Totally necessarily. When I ran the Dex, you can swap the gearbox back and forth to either have the motor run forward, or backwards. On-throttle, one way torques the chassis towards the rear of the car putting more pressure on the rear tires (on power push), while rotating the motor the other way torques the chassis towards the front tires (on power steering). So not even talking about changing pitch in the air... on the ground, the car drove completely different.

Default shock shaft size

Missing two e-clips for securing piston on the shock shaft. What size is the e-clip? I meant to put it in my pocket this morning, forgot it. Would like to buy a few on the way home this afternoon. Thanks!

Default shock build

Built 2 shocks last nite. I know that isn't much in one night but my carpal tunnel is really acting up. Surgery in almost a month. Back to question. When i pull the shaft out (shock extended) and turn loose of one it wants to recede back up into the shock body(not far but some), the other one does not. Which one has the air trapped in it?

It creates a slight vacuum when bleeding. Pump the shaft in and out a few times (what she said...) and this will even out.
