Just saw the latest images appearing on the Kasama site.


What this means is increased safety while plugging your batteries in! You'll now be able to hold onto the rotorhead while you plug in your packs single handed - good idea!!

I don't think a couple of deans plugs attached to a PCB are going to be up the task of delivering the high current demands of an electric helicopter of this size.

Not very well thought out.

Next.

Wow Dood, you can tell a lot from a CAD drawing. Do you know what the contacts are on that PCB? To help you out, take a look at Eagle Tree. Their data logger consists of two Dean's wired through a PCB and it handles 150amp no problem.

I agree Anthony - a single Deans easily capable of conducting 100A - putting two on a PCB a very elegant solution to the perennial problem of wiring up two packs in series. Usage of a PCB often used in heavy current situations such as car alternator or some speaker cross-overs or indeed the ET FDR.

Might be better though mounting the Deans inline with the leads from the lipos rather than coming in from the sides.

Think in its shown position it will be easy to connect packs with the Canopy on, although that front pack may need an extension or something as it will have to get around the motor...?

#edit# Looking again though, maybe front pack will reach ok...

The PCB looks to be double sided and connected through the board to ensure better current carrying capacity.
