What's the wall thickness of the tube to tap threads for the set screws? You gonna drill into the gearhead a bit too?

Hi Joe,

I am using the RC4WD Mil-Spec ZXL 2.2 tires. The diameter is 5.17" (131mm).

I am going to use some M5 set screws and I do plan to drill slightly into the gearhead casing. The tubing is approx 2.43 mm thick where I will drill through (just past where it steps up on the outside). The motors fit in the tubing without any slop so the set screws are to hold it in place and stop the motors from rotating or coming out. I also plan to use some liquid gasket seal, something that isn't permanent but that will give it some friction to help stop the motor from turning in the tubing.
