Last update for this year.
The new iteration of the Dark Chocolate deck is done. Nose and tail are longer by 1 inch each. Now it is possible to use 8" wheels on loose trucks without getting wheelbite.
We tried a slightly different color this time, so it looks more like hazel nut or caramel swirl chocolate
It got also skinned and sprayed logo.
First impression pros and cons:
Pro:
I really like the deck/deck shape and it’s looks. The size in combination with slightly concave and the drops makes it very comfortable for long carvy rides.
The power to weight ratio is in the 12S6P SS setup really nice. The Molicel 50A have plenty of juice for ~100km range on urethan and 60km on AT tires.
The max power output is still 12kW (120A per motor) which is more than enough for every situation on the streets.
The combination of the VESC and the MT V2 Remote is a smooth combination and works great so far. It needs more miles for testing though.
We combined in this version the LLT smart BMS with Metr Pro to have a comparison to the DieBieMS and the Flexi BMS. It is set for charge and discharge, so you always have balanced cells and a wide range of monitoring.
Cons:
The deck is in combination with the enclosure for a flex deck too stiff. We need to add more flex to it for the production series.
At high speeds it get’s wobbly on the current setup. I don’t know yet what it is causing the wobbles. It might by the MBS wheels, or I’m just not used to such big wheels on a RKP. However I probably need to try some different bushing setups for the rear truck to fix this.
The LLT BMS App is not stable. it does not influence the BMS function but you get quite often frozen screens. Does anyone have experience with a fix?
All in all it is a great experience so far. I learned a lot about manufacturing, ESK8s, engineering and business in general this year. Unfortunately due to the Pandemic everything is slower than it should be. But I’m confident that we can launch a great product for the next season.
What comes next?
We are waiting for the helical gear drive to arrive which I would like to offer as an option. We are also working on a new enclosure for the White Chocolate deck. Last step is to take the final decision on the production series parts and stress test them for a while in the final setup.
Finally I would like to say thank you to all of you which are following and contributing to this project. Without you guys and the whole community around it never would be possible to achieve what we achieved so far.
Marry X-Mas and a happy new year 2021
THANK YOU!
