I just want to say these things are fantastic. I have Newbee drives on two other boards and Finality Gear Drives on another and they are great too and special in their own way but these Jump Drives are so thin and light and for all steel gears, they are not as loud as I thought they would be. I am running them in 4WD and the total noise level is surprisingly quiet.

Yes, he’s been running 2 sets for a long time.

Poast has burned a few motors and ruined others from water while running these drives, but the drives themselves have held up I believe

The rain wasnt the issue. The snow while there was salt on the ground was the issue

I’m still running my prototype drives and they have been solid. I don’t even know how many miles I have on them now

sweet. I kinda want to attempt to adapt them to some SRB trucks. 
but for street/commuting, so they wouldn’t take the abuse my race board would give.
but then i was thinking no one ever really stops super super hard till they’re almost in an accident, and that would be the max stress moment on pushing the pinion past any loctite or circlip.
that of course made me think of @poastoast

I think his ruined some bearings maybe too but I don’t recall if that’s factual

@Lee_Wright Is there any chance we will be seeing a @tomiboi hubba hub adapter for Jump Drives?

i have a printable (blasphemy i know!) adapter!
been on mine for quite a while, i think i still have em

@ApexBoards @Lee_Wright Wondering if there are other motors out there that have circlip slots with the correct spacing?
Any chance you guys are going to sell flipsky 6354 with the circlip groove?

I was also wondering about this the other day, for lighter jump setups. Has anyone successfully dremelled their own circlip groove into a motor shaft? How did you measure the spacing? I wonder if just holding the dremel wheel with some pliers and already half-assembling the drives with the pinions on would work to get the spacing perfect 
Or if maybe something like diamond wire is more appropriate for the job

This is my thought. I have tried a 4wd jump drive setup with 6484’s (basically apex super predator build ) and I found it to be quite heavy. I think 4x 6354 would provide plenty of power and they are about half the weight of the 6384. Flipsky says 560g vs 1100g, so you’d save 2160g (close to 5lbs) on a 4wd board by switching to the smaller motors.
BTW, @rusins loving your mtb thread. I want to build basically the same thing, but on a trampa bigboi deck.

I considered using the motor as a lathe and just take a hack saw or file to the right spot but room for error is there and large.
I now have access to this bad boy though

The maytech black 6355s have the right shafts to work perfectly. I was running them on the front of my 4x4 before I got waylaid by high amp, High voltage builds.

Those would be great for up to ~16s builds, but IIRC they don’t come in 140kv, so not ideal for any higher voltage unless you wanna go really fast
bridgeports are my dream mill, sexy things
the dremel leaves a rounded groove which lets the circlip jump out
