ESC for 6x Gimsons??

[daveimi]

Can anyone recommend something for the above? At the minute a Victor or Vantec is the fave.

It is what I would choose as well.

6 Gimson GR02's 24V in a Heavy. 259 did something simular with 4 high end batterydrills.

I would use them with the 24/1 gearbox, and use them with 6S Lipo. That opens a wide range of speedo's and batteries, as well affordable chargers.

For redundancy, each motor his own Turnegy TZ85. Even bought @BotBitz , it's cheaper than a Vantec. And if reprogammed yourself, cheaper than a set of Victors (£200 for 2 Victors, without P&P or import tax. £130 for 6 TZ85's at HK UK warehouse)

Yeah, erm well I have a featherweight nearly finished being built inside a car wheel, and now am starting sorting out a matching heavyweight built inside of a lorry wheel. So I just needed a small compact drive-train. I'm unsure as to whether the bearings in the Gimson's will hold the weight, but I'm just looking at options for a couple of weeks before I get stuck in.

But a beefy ESC is the major expense so wanted it to be right first time.

I wouldn't use the original axles of the Gimsons to carry the weight of a heavy. Driving around ain't the issue, it's landings after flips or resisting heavy hammerblows.

An intermediate gearing and the wheels on more solid axles ain't a bad idea.

Don't have a clue how to make my own axles and gearboxes lol.

Can i suggest you stay with the feathers for abit longer then, a drill powered heavyweight isn't going to work, and will just be a waste of your money and time. I saw alot of Gimson motors/gearboxes fail at the weekend in the feathers and heavyweight is out of the question.

[daveimi]

Yeah I was starting to think that. It's frustrating having a lack of machining skills.

I would try to find 4 identical mobility scooter drives. you have the 4 wheels tyres gearboxes all rated for One (fat)person. so they should take the weight OK. Speed controller I would go for a Wotty I have used them for a while and have proved reliable. and can be used for the next robot.
