    ME1616 motor with sevcon gen4 size 6 80V low power??

    To get around the field weakening issue you can remain within its optimum RPM (about 3800rpm) and gear it appropriately based on the RPM for the speeds you want to achieve.

    EKartGo Project

    Depends how thick your busbar needs to be really, as its all about cross sectional area, most tend to overshoot it with little benefit, and can actually be a hindrance in execution (no ability to spot weld) With resistance welding there's a few tricks other than parallel welding which most...

    EKartGo Project

    I wonder if rather than using solder which can be time-consuming, opposed spot welding could be another choice? Copper sandwiched between nickel could potentially work, as I know that spot welding copper to nickel alone is difficult to get right even with specialist equipment. I'll do an...

    Nice one! Just a lot of persistence, and don't be afraid to reach out to people, I wouldn't have gotten far without that help! Would anyone be interested in the parts individually?

    Vector is a reseller for Eleek frames FYI, though they do interchange some of their components for higher quality variations (Brakes being an example)

    HobbyKing unable to provide UN38.3 and MSDS

    See this is the problem, people like yourself say its common knowledge but to the layperson it really isn't, and something that is required in our industry isn't being done even to its most basic level is something we can identify, but to those who don't have that type of training how are they...

    HobbyKing unable to provide UN38.3 and MSDS

    Well, this has been an enlightening journey for me. I've passed the information onto the relevant regulatory agencies as it's a public safety risk, especially if those shipments are incorrectly put onto passenger flights. They'll most likely disappear and reappear as another name.

    HobbyKing unable to provide UN38.3 and MSDS

    My thoughts exactly, I didn't expect much so I'm actually in contact with Parcelforce who handled the last leg of the shipment's journey in the UK, hopefully they know who signed off the package.

    HobbyKing unable to provide UN38.3 and MSDS

    I wanted to send along some unused batteries under IATA PI965 Section IA and requested a UN38.3 certificate and MSDS for one of their LiPO products and I got the below response... how exactly are they shipping goods around without those two things?

    30Ah 28s LiPo from 7s bricks

    Very nice Nuxland! Looks like those LiPO's are doing the job nicely, 8kg lighter, 5AH more, while pushing out more amps. Did you measure any temperatures?

    Li-ion cells cycle ageing

    I've always been intrigued about RC LiPO cycle life and decay, and haven't found much testing done that's publically available, would be an interesting topic of testing and would help validate/invalidate common assumptions.

    Battery case build

    Polycarbonate is a good choice, impact resistant but scratches easily, if scuffs dont matter its a good choice, I opt for black polycarbonate in my battery case builds now.

    High AMP battery build

    I would have to recommend the Samsung 20S or Samsung 30T or 40T if you want to tackle this, they punch a lot harder than the VTC6
