I’m getting them, but I’m not sure If I’ll use them tbh, recent ones are bending and I really do wanna make a bomb prof board, so atm I’m thinking about reverse TB mounts, did not calculate the belt lenght yet.

Apparently his longer mounts aren’t susceptible to the bending issues. Different aluminium plus anodised, but tb mounts are a good and safe bet, too :slight_smile:

Front and back lights are in for good.IMG_20181026_182548 IMG_20181026_182816 And she’s finally on all 4 for the first time.IMG_20181026_180525_542 I still have to get the final 3 orders of fsecs 6.6, ubec and longer mounts. While rebuilding the second motor, I have found a broken winding, so it’s either single motor riding or searching for a second 6374 TB and using the stator only.IMG_20181026_183518

I prepare for those torque moments when accelerating past 20 mph full throttle and anticipate the jerky moment when letting go at full throttle. I believe some of that is inherent in esk8? Is there a way to curb this?

Since the issue is basically just the drag, increasing the size of the motor pulleys should help the wheels spin the motor easier, thus reducing the drag. And here we go again! IMG_20181029_143445

If you increase motor pulley size you will loose some torque but gain speed

IMG_20181102_173438 IMG_20181101_162953 Soooo…the fsec and ubec are installed, the only things left are to wire the light switch, put a resistor for a back light and solder some connectors. So at this point I could put on one mount with a motor and start riding her.IMG_20181102_182925 IMG_20181102_183357

So the last steps are being taken. The LEDs wiring needs to be finished. I have used one of the older mounts, butchering a slot in it, in order not to have remove the pulley from the motor, once my other mounts come in. At the moment I have like 7mm of clearance only. Also shorted the switch on the push to start, since it broke, and did some cleaning on the electronics. If everything is good, tomorrow I should start using it, it really sucks a lot since I found one of my motors is kaput. So to the final build I’ll still be needing one motor, and probably even longer mounts than Dickey’s makes.IMG_20181105_181313 IMG_20181105_181431 IMG_20181105_181349

Not the happy completion post yet, but I’ll do an update. The board is up and running greatly, all the changes I’ve made from the V.1,4 build really stands out, especially the enclosure and the wheels. IMG_20181112_171058 IMG_20181112_171035 ! I already have the mounts from @dickyho but I still need to get another TB motor. Also the front led gave up after first 50 meters, so a new chip led was bought. The board is already beaten a bit. One thing I really don’t get is the gearing, I went from 14t pulley, to 16t one, but my wheels went from 110mm to 97, I can really feel the difference in torque drop, even then the last used single motor settings were 70A motor, 40bat, and now I’m using 75a motor and 60a bat.

Happy new year everyone!

I will try to keep this thread alive in some sort a way and do a small update! IMG_20190105_132909 IMG_20190105_132851 I have been riding it with a single motor with dickyho mount wich slips about 5mm down but holds strong from where. I have pulled the trigger on alien hev 170kv motors and pulleys for them, I did not found a logical solution of buying only 1tb motor, I really hope they will pull and keep strong. At the moment I’M tinkering with the led lights, changing the led chips, placement of the rear light and maybe I’ll add a small led strip, if I will find some space in the enclosure for another voltage convertor.IMG_20190105_134114 I’m really surprised how clean the electronics department looks after riding, compared to the last board, a major improvement! IMG_20190105_133114 So sum it up, I will install new motors, modify the second motor mount a bit, will need to make a spacer for the idler pulley, reposition the rear light, make the front light work again, re do the lights conections, I’m still looking for a shorter switch than the one i have, but can’t seem to find any. The deck needs re griping in a few places, and i should spend some time choosing the bushings for this thing. For the very future plans, i’m really thinking about gummies and maybe surfrodz, but the truck choice will be determined by plans on keeping this deck or not.

Screenshot_20190111-175645 While I’m playing the waiting game, I did regriped the deck in a few places, installed both mounts, made the spacer for the idler pulley and relocated the back led a bit. IMG_20190111_175416 IMG_20190111_175440

So I’m halfway done playing the waiting game: IMG_20190116_145508 These look a bit small compared to the TB ones, since the shafts have a good enough length, I don’t need to do anything with the motors, except put braided sleeve on the wires. Now the pulleys are the next thing to get.IMG_20190116_145811 I also already installed new bushings from riptide, but only will be able to test everything once the winter gets out.

IMG_20190121_190229 So the board is about 96% done! Version 2.1 I guess. I have lengthened motor wires and sleeved them with black/red shrink. The motors are only test fired, but seems I might be able to run idlers free. IMG_20190121_185956 Things left to be done: Cut the keyways. Loctite the **** out of everything. Resolder new rear light connectors to small jst plugs. Put another convertor, from the existing turnigy one, to get a 3.6v output for the front light. I have some flashlight stuff coming from China, that I’ll play around with. Set the new motors via bldc toll and she will be rolling! Well I still want to clean up my enclosure wiring a bit tho. Have some skateboard cash left, so I’m deciding between the two: Photon, or gummies, I will mock a 125mm plate up, to see if wheelbitee would happen or not.

Is your work bench a message table?

Well I only use it for soldering, don’t have another place to work in.

Looking awesome man.

Finally getting motors for my build Thursday, then on to other parts, like mounts, enclosure and all the electronics that go inside it… Slowly slowly

I guess if it work use it till you can’t. I wouldn’t be able to solder on a flexing surface

We can really see here the attention paid to each piece used on this beautiful setup! :wink:

What size wire sleeve did you use for the motor wires?

it’s 4mm, but I had to resolder bullets in order to push them on.
