Okay, installed the B4.2 MIP Pucks system this eve. I wouldn't suggest it for regular people, just wait for the B5 kit to come out.

It shaved off about 30g total.

Anyhow, here are a few pics. I got my running weight (minus any added weights) down to 1462g now!
I forgot my gear diff cover, so add 1g (if).

nope, used the rear hubs off my B4.2 and drilled out the Hub Pin hole since the B5M's are a tad bigger.

Has anybody tried the Avid Satellite wheels? Do the fronts fit well? Also since the turnbuckles are the same, I assume you can use a lunsford turnbuckle set for the b4.2?

Ratio is the same and the extra drag is probably not even measurable. Only reason i went down is the motor does not get as much air.

I cut the gears on my b4, but I really don't think it's worth it too much anymore. We used to do it for stock class back in the days of nimh batteries and brushed motors, but now with lipo and brushless you literally see no difference whatsoever. I also cut down the gear on my aluminum Topshaft and that didn't save enough weight to show up on my scale, it just couldn't register the difference.
I would just go with the aluminum Topshaft and pucks. Those savings are huge, and they don't really weaken your drivetrain.

The Satellite wheels works great, lighter and run true. The fronts are a tad tight on the hex but I just rock the wheel a tad when taking it off, no issue. The front axles are the problem and could be tolerance differences in the axles.

That is what I found with the Centro. I could not run the same timing and gear with the motor inside the car as I could with the B4.2. Temps were much higher with the Centro and the lack of air flow was the reason.

If somebody wants to order a b5m kit in germany, we have plenty in stock.

f.e. "Hk- Modellbau"

maybe the shipping costs are worth the car for you

Has anyone tried the aluminum shock mounts. Not sure what I'm doing wrong but there is a ton of slop between the shock mount and the hole in the shock cap
