Re: 360 - mini hypnodisc

brushless escs came from australia today, so i wired them up to give them a go...

Wasnt confident they'd be any good, but gotta give it to the aussies so far all good, and there tiny...only just double the size of a BR RX;



there hacked brushless tz85 turnigy escs... 85amp forward/reverse... slammed the motor into full forward/reverse and it worked fine on the bench... in theory nearly all brushless escs can be hacked to run forward/reverse brushed motors apparently... could be the next generation of speed controllers for anything upto heavyweight size in the future.

have you got a link to these ESCs?

Are you going for a Snail Drum design Dave?

Unibody, single tooth drum? Looks like a snail from the side, hence name.

Would the 25A botbitz controller be enough for a gimson motor? What if it ran off 24v?

A 25a ESC for a single Gimson should be fine, but that particular ESC is rated to just 4s, or around 14-15v. I doubt it would much like 24v.

Re: 360 - mini hypnodisc

well those tz85 hacked esc look very interesting

I'm thinking of using speed 900 but in a 4 wheel drive config (driving each side with one motor through chains with a gear reduction)
Works in my mind but alot of moving parts so to speak

Do you think the hacked tz85 would be up to 900's under load ?

Also , out of interest, what size wheels and gearbox ratio will you be running?

Re: 360 - mini hypnodisc

Depends on a number of things, mainly voltage, but if you're being sensible and follow the specs they're giving you I would say it would.

Re: 360 - mini hypnodisc

Just look through the Australian forum and check out what they're running off these escs peeps

Re: 360 - mini hypnodisc

PJ- nope, 2 tooth drum machined from a billet with bolt on teeth.

Drums being machined by Kenny soonish hopefully.

Re: 360 - mini hypnodisc

Drum machined...weighs just over 3kg, will be going around 15000rpm.... just need to machine some bulkheads out of some alumec next....that takes effort though.
