I basically finish the setup, I put my protection, Iām preparing to go out and there during the test empty ā¦ I realize that there is a loud problem! ā¦
I have yet done the programming (vesctool 0.94), as usual, and everything is normally and well spent (Wizard, FOC, sensored ā¦ ppm etc. canbus ā¦).
But it looks like ā¦ I do not know hell, the more I put the gas over it cog and vibrates with crazy sounds. I never saw that before. Did this happen to someone?
I only change the motor on my last setup (and le drive system, but the drives works well when tested empty), and place the VESCs in the center now, nothing crazy (just add 20cm of extension wire and the 60cm sensor wire extension).
So ā¦ :
Iām going to redo the extensions phases wires I guess (as they were a bit too short anyway)
all recheck at the welds and connections.
As well as update to the penultimate version.
And,ā¦ I will see.
Then, the last solution, to put the VESC back again (top of the motors ā¦ ), but I do not see why it would walk again and not there ?!
During this time, it is a beautiful WE, with +20Ā°C outside (almost +25Ā°C exposed) and I just can pedaling on my bike
Another photo to give you a little something during the restart ā¦
What a pleasure to go back on it !! I feel really good, and it carves damn more than the old setup, really too eager to ride!
Ok, so! After this little adventure, I proceeded to debug and change extension wires (with longer), new fw (3.40), and I was able to finally try this madness, but very / too short (just a few kilometers for testing)!
Very quiet (and short so) little test ride yesterday (yes, the video is a little useless, but I was too happy to finally ride mini 1: 5 MBS M2 extra large! )
And, a longer ride tonight so peaceful !! (itās been 8 months without riding a monster ).
I will show you more tomorrow
haha ā¦ yeah, this summer was so intense for me ā¦ so much good memory listening to this song since I was kids until now !
Iām sure to listen to it every month minimum ^^
I love how the motors disappear with the gear drive, looks dope!.
Do you know what was the problem with your motors (jesus that sound )? The wires, maybe firmware?
HAha, 2nd ride was great with the good weather ! Cool cruising in the city.
Still not a long ride but it was good (forgot to start the record ā¦)

But today, going to my grandmotherās place to have a drink ā¦ :
I have done maybe 15/20km totally ā¦ so much frustration, and I still not try it in OffRoad.
Now, the magnet (the one vibrating at 1st) is definitely loose!! I can hear it grinding the stator. So I have to stop riding yesterday.
One week later my 1st mail, I get an email from FlipSky telling me that they will come to me soon ā¦
Then, Friday, I got an email telling me something like :
āwhere did you get them? we do not sell 6380 motors.ā
:
I swear, I do not 'toshop this! ^^
Well, as I suspect since the begging, itās happening !.. Battle startedā¦
Ok, they beleave me now
They ask me to open it to see if itās not a bearing or a loose magnet :
In fact, they are all loose, I can move them individually
If you compare a 2018 motor (FS) with my 1st one from 2013 (on the left), itās day and night :
On the old APS, all magnets are resined/glued on the rotor with retaining ring both side, pretty clean (as the Maytech).
Also, I was modeling wedges for the corners of the central box, and I think Iāll try to get the vesc out. Itās not that practical in the covercles, every time I want to open it.
So I mod something like this (maybe with the heatsink inside) :
And I realise that I havenāt shared all the detailled photo here !
Thanks a lot, mate !!! it was a totally unnecessary vid. 1st test, around 25/30kmh max speed and just on road
But Iām glad it affect you like me !!
About the new MadBox, vertically, a front panel heatsink will looks so cool ā¦ but then, itās a pain in @ss to access to the vesc.
I will definitely let the heatsink/holder āinsideā so.
I try patiently to take care while waiting for a return of FS following their request for photo motor open, following their request, more than a week ago ā¦ since, it is again the complete radio silence!
Each message, I must wait more than a week to hope an answer,ā¦ it is really very painful and frustrating ā¦ (!!!)
Well, I will set other older motors laying around I guess ^^ (except that I have to make custom shaft for the Geared Drive).
I also received the extender (link shared by @banjaxxed ) but I make a mistake, itās not the same step screw, I didnāt pay attention to that sh!t (plus the bearing didnāt fit right on it)
It was a so cool solution to make this MBS Gear Drive compatible with 9" !.. (Maybe they exist in the same step or we should order some specific one ?)
Others solution is to buy Megastar and new e-toxx adaptor (ā¦ around 4/500ā¬ ā¦)
Maybe 8" is finally fine ā¦ no,, I would not give up there !
And make new axle, for the hanger, sound also maybe to much to solve the issue.
Yes, sorry, pitch (! not step ) isnāt the same ā¦ I guess ā¦
Idk if itās because I can screw it well by hand or if itās the pitch. But it doesnāt seam easy.
! Maybe with a m10 screw on the other side the help āscrewingā (I will try if I find some).
Also the bearing didnāt fit too ^^ maybe they have to be pressed.
donāt force it! In fact stop trying altogether, the pitch on those adaptors is 1.75mm (coarse).
I 've taken a closer lookā¦I think the pitch is 1.5mm on M12 mountainboard trucks?
@mbs@trampa would that be true?
ā¦and sorry. I guess I should have confirmed but was excited to share a possible workaround
Probably it is not designed to be used in this way, so 15mm would be a ballpark figure rather than machined to within 0.01mm tolerance, I am not sure on the caliper-measured size, but probably they could be spun on a drill to fitā¦but no point if they are the wrong pitch
If the 7/16 part was 5-6mm longer, this would be perfect. The hex on the end is not completely necessary, it can be replaced with a bolt to keep the hub on & reduce machining cost/hassle.
Maybe steel spacers with M8 hole in 15mm OD like this
Drill it 36mm in with a 25/64" bit (cobalt) like this
And tap it with a 7/16 20TPI UNF tap
Come in from the other side with a M10 drill bit and tap for the bolt
I do not think ā¬4/500 is the way forward. No plans to buy myself out of this with Megastars and Trampa adaptors either (I hope!)
Sorry @Riako last spam on your build thread ā¦ maybe itās easier than that, simply get someone to lathe off the hex on the stock extender, instant extra 6mm, then use M10 bolt in place of the grub
@rey8801 any chance we could impinge on your good nature for dollah?
