I’m going to use 16s8p p42s TB 170kv 6380s with 3.35 gearing on metro 155s ran the numbers should be good for 45 mph… will lower ratio if I feel confident.

TO ANYONE, with the (Gen1) 1/16" chromoly motor plates. Ship those to me and I will exchange them out for the CNC 1/8" chromo plate at no charge. You take care of shipping costs. One week turn around est.

Normal trucks only have the tip of the pivot cup for suspension, these have far greater bounce. They have far more direct steering. Regular trucks turn as a side effect, not direct. They cannot set up an oscillation.
These are REAL benefits to going fast. They might even use less foot compensation, so less fatigue.

@MoeStooge my rear truck feels a little more wobbly than the front. Is that because of the weight of the motors or do i need to tighten something to lose that feel? It’s not a speed wobble but definitely feels more loose than my fromt truck
By the way you ruined me. I tried riding some rkp’s a few days ago and all I could think was “These feel like garbage!” NKP has spoiled me for sure

If everything is tight I would say quarter turn in on your rear bushings, drop the rear bars to the roadside mounting holes or both.
If there is an issue where the feel has changed.
Start by backing off the bushings and checking the aluminum axel to main spherical lock collars that the bushings ride on. They need to be tight with a drop of red Loc-tite on each.

Also check the axel to radius rod collar bolts.
Tight with blue Loc-tite.

I asked, it is just the threaded collar. Would be good to know the torque spec for that screw.

I plan to tighten that screw with the intention that If I ever have to take it out it I’ll have to weld the allen key in or else it’ll strip and slather the inside of the collar with either red or green locitie

you could prob switch the screw out to a hex head one vs the socket hex and get more torque on it but it seems to be fine with just the hex key.

I’m just not gonna buy these trucks until someone makes bulletproof motor mounts for them. Apparently, @moon is doing this.

Plate collar socket bolt tightens @ 20inch lb.
Collar socket bolts are black oxide alloy.
Threaded clamp collars have twice the contact surface area than smooth bore.
Do not over tighten. Snug to firm is plenty.
If you are experiencing an issue, check the collar gap when tight.
If the gap is touching I’ll gladly exchange out the mount.
We run 12kw on these mounts without issue.

Did you anticipate this issue when designing these trucks ?
The only thing stopping the motors from sliding downwards over time is friction. Using friction for this purpose has been tried before and it doesnt work. Boardnamics used to do it and now they dont.

@jack.luis I appreciate your concern and experience.
I guarantee this has been thoroughly tested and a non concern.

And I never got close enough to see if the motors/mount were slipping
