I caught up with Simon a reader and commentator on this blog last weekend and had a go of this board.
He’s still working on refining the setup (aren’t we all) but he’s got a lot of run time in and is currently getting a 20km riding distance.
To run through some of the setup.
- Abec11 Wheels,
- Arbor Pintail bamboo deck
- Caliber trucks – Which have a square profile which makes it better for the clamp style motor bracket)
- Alien power systems larger drive cog (He got one of the early version)
- Aluminium motor bracket – This is own customer design which he used his CNC machine to cut. It uses a clamping mechanism to the trucks so they can be removed relatively easily and use a rotating slot screws to tension the motor. Hes going to make a bracket for my board for me so hopefully I ‘ll have some more pictures for you shortly.
- HTD 5mm belt
- Motor: http://www.hobbyking.com/hobbyking/store/__18181__Turnigy_Aerodrive_SK3_6364_190kv_Brushless_Outrunner_Motor.html however, he’s been looking at even lower kv motors and maybe a dual mount
- ESC: 150A Hobbyking 1/8 truck (same as mine, but with he’s added a few more capacitors, you can see them with the extra wire on the bottom)
- 3d printed battery an ESC case. This one is a prototype hence the velcro to avoid drilling into the board until he finalises the design.
I had a ride of the board and it feels good. Smooth acceleration, the flex of the board feels good and its pretty quiet. Simon tells me that handles most hills without a problem.
Simon said he had an issue with motor timing where the motor jammed up if you tried pulling really hard on the controller.
We had a good chat about potential improvements and some tweaks that Simon’s looking at including potentially using sensored motors to improve smoothness of acceleration and improved braking power. As well as implementing a dual rear motor system with a slightly shorter motor to give more torque in acceleration and deceleration.
All in all it was good to have a ride of someone elses board (especially one thats working much better than mine), talk about some of the issues that are involved in getting these things to work nicely and chat about some of the interesting design people are coming up with for electric skateboards.
