Side view of the magnet.

Are those bushings pressed into the motor? Any chance to swap with bearing(s)? That should be a significant improvement.

Wrong pic but the bushings are clear in the other pics in thread.

The bushings are inside the magnetic core which fits inside the rotor, a 2mm OD x 1 mm ID ball bearing might be a bit hard to come by, but even if you could find one the benefits in this size and type of coreless motor would likely be marginal at best.

The shaft, magnet, and coils act like a magnetic bearing with the shaft actually floating inside the central magnetic core and wound rotor’s magnetic fields. As long as the bushings are centered correctly, the shaft is straight, and the pinion to spur gear mesh does not force the shaft against the bushings there is almost no contact between the shaft and bushings when the motor is running.

Could possibly be done by making a new magnetic core and sacrificing a bit of magnet for ball bearings, but centering the new core and lining it up would be brutal not to mention the weaker magnet.

Agreed... just thinkin' aloud

BTW, my buddy just got back from Japan today and guess what I got in my hands

You know, even if Kyosho brings these to the US, I don't see a big adoption rate at the very high prices. I mean at like a $30 screwdriver we're talking Pentagon pricing.LOL

Size chart with Fitting Parts Set contents, for the current and some of the proposed bodies. Measurements are in millimeters. Not 100% accurate yet but better than nothing.

Hey LBRC, do you have a copy of this PDF that you could please PM me? Looks like Kyosho yanked this one. Go figure considering it is one of the more useful chunks of data for fitting kits.

Hopefully they’re just moving it. Have the file but it’s 1.04MB too big to post or PM. If you email the address under my profile I will attach it to a reply.

this issue has been resolved for a looooong time since we began stocking the X-Power 200mAh Battery

Where can I buy a LBSpd Muhaha (~1.7 ohm) motor?

I wanna buy and try one of these.

Thank you!!!

Where can I find the connector?

Connectors in dnano are jst-zh with 1.5 mm pitch, a 2pin male for the motor.
You can find them in most electronic store.

Thanks again!!!
