A good brushless drum spinner motor/esc match?

[skmattwell]

Looking to add a drum or vertical spinner to my 4WD featherweight (presuming that's plausible). Is this a reasonable pairing for a brushless weapon motor/esc? It will all be running off a 4s battery.

Is this a good idea or a death sentence?

Motor is definitely good from what I have heard. I am sure a few folk on here use them (or variations thereof) in the drive so I would be confident in that choice. The ESC, for a drum spinner I don't think you'd need a reversing ESC but otherwise, looks OK to me though extra headroom on the amperage might be a good idea as well.

Excellent. My thinking was with a reversing esc is that I could change the direction of the drum when inverted so it would always uppercut? In terms of amperage, would you say one of these would give me a little extra wiggle room? I only picked an 80A because that's what it suggested on the motor description.

I've been looking at those WiFi reversing ESC, but the reversing function is enabled by using a second channel as the direction control and insinuating that it has to be stopped before being applied to avoid damage. I'm thinking a flashed red brick would be cheaper and better, but doesnt look as nice.

I am doing that with my Featherweight at the moment. It looks a bit ramshackle with the electrical tape holding the heatsink in but it'll do OK.

Any idea where to get the Atmel flashing tool? I dont want to go through the hassle of soldering wires on again, but it looks like HobbyKing are out of stock of this.

Thanks for your help guys. I did go for the wifi reversing one in the end, however I don't think I'll actually be using that feature by the sounds of it. It was more of a basic query to make sure I won't blow the 70a motor with a 100a esc as I've never worked with brushless motors before.

[Ocracoke]

I might be wrong but the way I think of it is that the ESC is a bridge between the battery and the motor. The motor is the power drawing element so as long as the motor amperage + 10% never exceeds the ESC rating, then in theory you should be OK.

I can find the USB tool quite easily: https://www.ebay.co.uk/itm/201234598699 but the atmel/atmega socket flashing adapter (the one you press the pins against the chip with) I cannot find at the moment.

Its very difficult to get the atmel programming chip device now as Hobbyking no longer make them. best bet would be to make one using pogo pins and some hot glue.

Also, by reversing the direction of the motor, yes you would 'up-cut' your drum but the tooth profile will mean you wouldnt nip just bump the opponent. That is unless you have a lump instead of a typical tooth shape.
