2 shift or not 2 shift?

[Claus]

When I had a King Hauler I had the 3 speed, a Tekin FXR, 45T motor, and a 4:1 reduction. My running is all in the house and I loved that setup as it gave me great control and different speeds. Now that I'm building a Wedico I'm using the aluminum case 3 speed with the belt reduction and some plastic gears inside. I'm also using the dual motor combination box and 2 Buhler motors. My truck is not even near finished yet and I have already stripped 3rd gear and 2 gears in the combination box. I have rebuilt it all but have now lost faith in the system.

I want something more bullet proof but hate to sacrifice, should I go gearhead motor, or different transmission that shifts? I have looked into putting a Tamiya transmission in my truck, it could be done but won't be a real simple thing either.

I may finish the build with what I have and look at a repower the next time gears fly south on me.
