bjorklo 1620 Posted November 27, 2014 So I'm wondering how have made the best gearsystem/boxes it don't necessary have to be Tamiya and you could choose a rear gearbox from Egress and the front one from Top Force (just an example). I got most experience with vintage buggy's so I'm thinking about the Egress, both front and rear) and the Top Force (front), what do you think? The criteria should be Design Durability Gear ratio If you know the gear ratio for the gear box you think is the best, please state this as well. Share this post Link to post Share on other sites
MadInventor 3884 Posted November 27, 2014 I think the old schumacher CAT had the simplest, most efficient, and lightest transmission (Just 3 belts, with cams for tensioning the belts) Also the Optima MID had a great combination of gear drive and belt drive (Gear drive to the rear axle and belt drive to the front diff.) The Clod Buster has probably the most robust transmission, particularly from the vintage vehicles. 1 Share this post Link to post Share on other sites
Yonez 180 Posted November 27, 2014 I can't chime in on the best transmission... But I've always wondered what the idea was with the hugely complex Hotshot gearboxes. I love them silly, but after seeing how simple modern buggies are, both shaft and belt ones, you've gotta wonder. 1 Share this post Link to post Share on other sites
Theibault 1535 Posted November 27, 2014 Pretty much any ball or gear diff from any manufacturers that make racing buggies. 1 Share this post Link to post Share on other sites
Gruntfuggly 562 Posted November 27, 2014 I know the SRB is gearbox is limited on ratios and probably not very efficient, but it always impressed me with it's sealed design, cool transparent covers and it was bulletproof. Share this post Link to post Share on other sites
Backlash 481 Posted November 27, 2014 For what purpose? Are you wanting to scratch build a buggy? For me, I would say the gearboxes from an Associated TC3/4 touring car.. Yes, I know its a touring car, but its already been shown that they can be adapted to offroad.. Reason is they are ball diffs standard, have tuning options such as light weight (plastic) outdrives.. You can have a spool or one way option.. They are quite compact, extremely efficient, sealed quite well, and are shaft driven... Ratio is 2.5:1... I imagine the ones from the newer B44 buggy would be similar.... 1 Share this post Link to post Share on other sites

markbt73 5316 Posted November 29, 2014 I'll second the Optima Mid (and Lazer and other derivatives). The biggest drawback to it is that the entire car must be disassembled if anything ever happens to that belt - and I mean the ENTIRE car. But it's pretty strong, and the whole thing is very free-running and quiet for a belt drive. 1 Share this post Link to post Share on other sites
