The reason I want it is because it's difficult to tighten the ball studs /nuts while holding the chassis flat, the screw just spins around. Of course I can hold a driver/wrench on the other side but wouldn't this prevent the chassis from being tightened evenly and flat? Like how you wont tighten a TC top deck by holding the chassis on your hand? Or does this not matter on the f104?
I'll have some around January. The design will work with 103 and 104.

Spur gear are plastic, so that when something happens it takes the brunt of it. If you use a metal spur gear, the damage will just go somewhere else.

none that I can recall bro.

youre best bet is to just make sure you get the mesh correct and really tighten the motor screws... metal spur gears and pinion gears only seem to work on nitro cars...

The stock plastic ones can be very durable...just make sure you mesh them right.

Yeah i had it meshed pretty well, but the rear axle carrier popped out, and the rest is history. Was hoping there would of been a nice alloy one.

Would you suggest using TRF415 spurs like 54055 or 51056?

Very few nitros had metal spur gears...metal on metal for an external gear just does not work very well. The friction is migh higher and heavier. Internally in a gear box works fine because you can keep them well lubricated.

In this case if the rear axle carrier had come off and it was an aluminum gear it still would have been chewed up.

Does your F104 have a plastic right side pod motor mount, or the aluminum one ?

Yes, and the plastic one will not hold the motor in place very well at all.
Could be the issue he is having with stripped spur gears ?
