The only thing thats "faulty" designwise is the hole in the chassis for tightening the grub screw of the pinion.
The motormount as well as installing pinions (non Hudy ones here as well) works just fine for me.
Just out of curiosity: how are your pinions shaped for not working with the motormount?

I will take some pics when I get home. I am running Robinson pinions and the xray off set spurs. There is no way to get to the grub screw from the bottom and no direct way from the top. I could see getting the job done from the top with a ball tip possibly but I don't have one that small.

I am using epic pinions. I know they are very very rare and forged in the mountains of Tibet by monks with specially designed Lhasa Apso's bones as tools, but I figured they might work on this car since they work on every other f*in car on the planet. According to the report from Martin they tried hundreds of motors, thousands of different types of servos, millions of different types of body clips, but I guess pinions did not make the list. Good news is that my current body clips are in fact working perfectly. No clearance issues there!

Seriously, The issue is that the set screw ends up too close to the motor which blocks the access from above and below. It is something I will figure out how to deal with, but this is one item they did not coptimize very well. Maybe a rubber Hudy hex wrench made from nano technology might be in order to solve this mystery of the ages.

You should go ahead and invest in some XRay pinions. They generate more grip.

I also get to it through the top deck. In thinking about grinding a groove in my nice Hudy wrench to help fully seat it.

Crap, I think I messed up gluing the chassis.

I got a bit overzealous and glued some other screw holes, but the CA dried lumpy. How do I clean the bevel of the countersunk screw holes?

Preferably without doing more damage?

I haven't tried this, but it might work. I just thought of what I might try if it happened to me.

poke a small hole in a piece of sand paper. Put a countersunk screw through the hole from the back. use hex driver to hold the screw in the hole and then wiggle the sandpaper back and forth, maybe while also turning the screw in sync.

Just an idea...good luck

I think that will work or even CA a piece of sand paper to a screw and use a wrench or drill to spin it . Btw I glued all my chassis holes with a qtip and thin CA worked great
