Hey Joe:
It looks like you purchased TB DD motors. Whats the plan? Complete DIY or Revel Kit Transplant?
Hey! Very excited for this projectâŚbasically a next level Revel.
Psychotiller 42" Llama Deck+Enclosure
115mm Onsra Wheels
4WD TorqueBoards 90kv Direct Drive Motors
ChiBatterySystems 12S8P P42A Battery
Dual Unityâs
Firefly Remote
Should have 1451wh, be able to conduct Endurance Rides without issue & more power than I would ever need for speed & hill climbing.
Just waiting on the wheels & deck/enclosure

So are you using any revel kit parts? Trucks? Do they fit? What trucks are you using if you did not order them from TB? You said the motors arrived. Maybe you actually got the entire Drive assembly.
No, there are no Revel parts being used. The DD motors come already mounted on trucks.
Was going to use the Boosted 105mm wheels but as you can see the clearance is a bit iffy with them.
I saw those wheels! Very interesting design. I went with the Onsra ones cause one of my friends has them & they ride really nicelyâŚplus theyâre 5mm larger which will probably be good given the size of the 90kv motors.
Aha. I call that a drive assembly. Cool project. Keep us posted.
You went wiht 90 KV for more torque on larger wheels? Is that correct? or is 90 KV less torque and higher top speed?

Less torque but higher top speedâŚwith 4WD though, the torque will be more than sufficient.
4WD should keep all the motors a lot healthier in general. Not as much strain as a 2WD setup.
iâm thinking the same wheels for my TBDD. do you like them over the TB110?
Yes, I donât really like the urethane formula of the TB 110mm wheels. In my experience, they tend to harden up very quickly in the winter.
If youâre looking for a straight up urethane skate wheel, I would recommend the ABEC 107âs. Theyâve always been very high quality. Iâve run them for years.
Hey guys,
Thx for advice pkasanda, revel have confirmed that its a rusty bearing, but fortunately the rust hasnt affected the movement of the motor so bith spin the same atm.
I will tey to use more lube and see if that fixes the issue. I will tey ur other steps too, i appreciate the advice

Has anyone had the issue where your board randomly accelerates when you are trying to pull back the throttle on the remote to brake? I almost got bucked off my board from this.
Iâve never experienced anything like that. However, the few times that I have tried to operate the remote with gloves, I have found that switching from throttle to brake has on a few occasions sent me off balance with a sudden unexpected jolt of acceleration. For me, the extra 1/8th inch of leather at the tip of my thumb catches the throttle and gives it a bump just at the moment that iâm trying to switch my thumb to reverse mode. Itâs they type of problem that one might expect at this time of year when the cold weather hits.
The solution to this particular problem is to not wear a glove on the remote hand. I wear a coat with sleves long enough to act as a glove. Another solution is snowmobile mitts that are large enough to operate the remote inside of.
Or there is this:
I have a vague recollection of syncing a remote while the throttle was not in the neutral position. I think the result was a bit like what I see in your video.
So try resyncing the remote again with your hands clear of the throttle knob.
If that does not workâŚ
Can you take a profile picture of the remote. Is there a gap between the remote and the bottom of the throttle knob? Could you have gotten dirt into the track.
If you donât have clearance between the remote and the bottom of the knob then remove the throttle knob to see if it solves the problem. Otherwise you need to disassemble and clean or just order a new remote.

I cut out the last bit of the video because the file size would have been too large to upload, but it does go back down to 0mph after this without me touching anything on the remote. I also had it in speed mode 4 and it would go all the way up to 28mph without me touching anything on the remote. This also doesnât happen consistently. So I donât think it is an issue with there being dirt in the remote. I started having issues over 6 months ago when the board randomly lock in at 5mph or less automatically without turning on cruise control. This wasnât a big deal at the time since I could still brake and accelate normally. When I started having the issues with random acceleration, I thought it was due to the battery. I just got a new battery and the issue seems to be even worse now. If i was anticipating on buying a new remote I would have just sad to hell with the revel kit and not have bought the battery.
Anyways, I found this: https://electric-skateboard.builders/t/odd-accelerating-braking/61688/7
Maybe I just need to put a ferrite ring on the receiver wire to block out electromagnetic interference noise from the esc? Maybe I should try moving the receiver wire too? Everything is pretty snug in there so Iâm not sure if that would work. I also donât know which one is the receiving wire.

There is a very thick layer of dust and grit coating many of the interior components. The thick film could be salty and/or moist. This is the first place you should look to for the source of the abnormal behaviour.
Others have posted here that certain revel kit problems were resolved after a thorough cleaning. The reverse side of the battery terminals was mentioned in that case. In your case, there could be many different locations that need attention (antenna wire, Antenna Printed circuit tape, capacitor terminals, connectors, power button, charging port. Also, if your ESC compartment is this dirty, then I would expect similar probelms inside your batteries.
You have reported multiple different symptoms so there may be more than one area that has been affected by the dirt/salt/moisture infiltration.
Cleaning might not be enough. I hope it is but your picture shows alot of potential for damage.
I think you should ask for more advice from others in this thread and from revel kit before you proceed,
Becarful to note how wires are run when you disassemble. Take lots of pictures. When you re-assemble, be very careful not to pinch any wires including otor wires and the antenna wire. If you pinch those the wires wonât perform properly and the damage can be permanent.
After the reassembly, Check for a uniform fit between the top and bottom shell. If it is not uniform, you have pinched a wire.
You seem to have been travling in some unusually dirty/wet conditions. I recall that @BearBoi had some advice for coating the components with an anti corrosion spray. Also, I posted a video with a few methods to enhance water/dust resistance.
I just noticed revel released a 3A fast charger, anyone tried it yet? https://www.revelboards.com/collections/parts-more/products/3a-fast-charger-charging-dock
Makes me wonder if it would be possible after all to just feed it 3A without buying this, or if it has some special tech inside specific to revel.
Does this mean I can use my Meepo charger which fits and has the same voltage and actually works just fine too. So far only used my Revel Charger. Might use the meepo if I need to get a quick charge.
Also seems like Revel is finally selling the stock wheels.
