First of all: Don’t judge me because of all the ugly tape. I have not had time to finish my enclosure. Half of it has been sitting in my workshop for weeks now .
So I have been riding this bad boy for about a month now and I love almost everything about it. I have build this board similar to Namasaki’s build.
Here are what parts I used:
- 5 LiPo 2S 5000mah 40C batteries from Turnigy
- 10S BMS from Bestech
- Maytech VESC from APS ( have not had the best experience with it. Read more about that here )
- APS 200kv 6374 Motor (great motor btw.)
- a little battery indicator from APS as well
- motor mount from APS ( great mount, just don’t use it with Paris Trucks. read more about that here)
little question: How much do you guys tighten up the belt? Because I think I have it tightened up quite good, but when I break abruptly it still slips a lot.
Some other facts:
I weigh about 90kg (198,416lbs). Topspeed is 43km/h. Hill climbing is easy, but only for shorts periods I never managed to get below 60% charge. I once rode 10km and still had 70% charge left. So there is that.
What I do not like about the board is the following:
The motor is great and a beast, but to big for my taste to be honest. Also I am not a fan of the single motor build. I did it, cause budget reasons, but I am soon going to upgrade to a dual motor setup with much smaller motors. Just to split up the load and increase breaking performance. Also after taking on a rather steep hill for about 3min, performance drops a lot. I takes about 30sec - 1min of rest till I can reach the 43km/h again. I don’t now if thats because of the motor or the BMS or the batteries though. So my plans for the future are upgrading to a dual motor setup, but probably not before next year cause, the board has more than enough power to get me through a big city. I won’t be taking on hills with it for a couple of month from now on.
One more thing:
I got fed up the vibrations pretty quickly and decided to do something about it. I once was at a “company fair” ( just a lot of companies showing of there stuff to gain interest). There was a company that produced some kind of anti-vibrational mats. They are mostly used to reduce the vibrations caused by trains, but they had all kinds of products. A little example: They droped metal balls with the same weight from the same height on different surfaces with and without their mats and were showing off that the metal ball basically did not jump at all when it fell on their mat. I don’t know the name of the company anymore though . Will do some research. Anyways. They had little pieces of different mats there and I asked them then if any of these mats could be used to reduce the vibrations caused by the subwoofer in my room. They were not sure, because they were not designed for that purpose, but they gave me 4 of those little samples to try it out. So I did and it helped. Not much, but a little for sure. So I don’t have that woofer anymore and those little mats have been lying arround for quite a long time and then it hit me. Since I use risers already and those mats are pretty stiff (there are smoother once and stiffer once. I have two of each)I could exchange them with my risers after I cut them to the right size. I tried a few different combinations with risers and without and so on. Here is an image.
