There are several problems with my DIY now: the remote does not power up any more (need a new receiver and remote); the voltage display show a percentage (always showing 100%) again instead of voltage (need to fix a switch on the display PCB); and the left rear wheel is slightly coming off again (need to find a stronger glue). I changed the remote today. I sealed the enclosure with silicone to protect the board from water damage as much as possible. After removing the screws, some more work was needed to remove the silicone before I can separate the enclosure from the deck How does everything look like inside after more than one year? Will there be a lot of dirt? Will some wire insulation be damaged by rubbing against the bottom of the deck? Will some connections become loose? Let me flip the enclosure over! Wow, much better than I thought! The motor side foam seal moved inward somehow and dust went in. Not a big amount and I am happy. The height of the CAN Bus connector had me worried that the three wires would rub against the deck and break. Instead, they were just bent flat against the deck. No sign of abrasion at all. The MayTech Remote receiver is just a pcb with no housing. To keep it in position, I secured a piece of heat shrink tube (yellow) on the enclosure as a sleeve for sliding the receiver into. I need to replace this receiver with the one that came with the Winning Nano Remote. (As before, I covered the battery with plastic wrap to avoid accidental shorting. Looking at the instruction sheet, I could see that the pin layout was somehow totally different! Anyway, I tried pairing it with the Winning Nano Remote. It was not successful. And then I realized that the receiver was for the Mini Remote that I didn't like. Somehow, I didn't store the receivers with their matching remotes together! A bad move. After a while, I located the right receiver and made a successful pairing. I engaged the brake and the motors just ran wild. I had to power the longboard battery down immediately. After setting the Min and Max Pulsewidth with the BLDC tool, the Winning Remote was working normally. I attached the receiver on the enclosure with industrial strength Velcro. After that, putting all the screws back on! As before, I sealed the enclosure with silicone and put heat shrink around the screws to make hand carrying more comfortable. (If I ever do another DIY, I will make a custom enclosure that will fit perfectly with the deck curvature.) In retrospect, I should have tried to fix the display problem too. Well, may be in 2019!
