Still waiting on parts, but it moved under power today. Rear mip shaft is in and worked out great with the longer drive hub. Waiting on the dogbone for the front. The aluminum i needed for the brace/ battery mount showed up a few mins ago so I'll get started on that this weekend.

I didn't push it on the test run since I only had 1 screw holding the entire front end but it looks like it'll work fine. The slipper is really tight. I had to back the nut well off the locking portion to get it to slip at all. I'll mess with that once I finish building.

Did a little more on the camo today. As of today it's basically ready to run other than the front dogbone. I also have metal trans gears coming, but nothing else i need a far as parts.

Today I made the chassis brace and got the battery tray mounted.







Once that was done I decided to try something a little different. I had ordered some yeti knuckles and carriers to see how much effort it would be to mount them on the camo. Spoiler alert, it pretty much bolts right in.

I needed the larger outer bearing (5x11x4) and that's it. The axles do fit, but I think redcat uses the inner bearing to retain the cvd pin so I'll pick up some yeti shafts before I try to run this setup. The only thing I'm not sure about is if the yeti uses longer axles than the camo (i don't know how wide the yeti is). This should open up a lot of aftermarket options for the camo.


Please ignore the long adapters. I removed them after the pic was taken. Lol

Get some 2M diff "glue" that should help your tight LSD quest.

Nice work, you're pretty crafty with that plate aluminum!



I was also considering the Axial gearbox, but after doing some gear calculations the top speed would be around 17mph on 3s, a little too slow for me. That SCX10 gearbox has a 2.6 reduction while stock was 1:1 (not considering pinion & spur ratio).



What is the 24mm drive hub you speak of? Am I missing it? Didn't see it in the pics. Just an extension for the rear output of the gearbox.

Yeah, I was doing some math on the gear ratios yesterday and it looks like the overall drive ratio is right at double of stock (~16:1 vs 32:1). With the tires I'm running and the 56/13 gears i think it'll run around mid 20s mph with my 3800kv motor on 3s. I think I can fit a 15t pinion for a little more, and worst case maybe step up to a faster motor. 3s was borderline uncontrollable before so I think it'll work out.

I didn't really consider the gearing before I started. I was seeing a lot of people run a 3 gear trans in the Bomber and figured it would be a good fit. Main difference i think is I could fit a much bigger pinion in the Bomber if I used this trans.

Here's the drive hub I mentioned. Just a cheap option to extend the rear output (driveshaft) a little since I had to mount the trans further forward
