Default BRUSHLESS ESC sizes..... when will they get smaller

Currently who makes the smallest BL ESC?

How long before we can buy something smaller then the fat(not "ph" phat) ESC's we used to run in the 80s/90s.

I know cost is an issue. But all these years in the Brushed world our electronics got smaller and smaller and the chassis got thinner and thinner. Now these FAT BL ESC's are making my cars look ugly..

any one share my pain?

LOL

Tekin

There R1, and soon to be RS series are the smallest so far

But the KO speedo looks really small also

As far as I know the Tekin R1 series is the smallest, but it is limited to sensorless operation. Your call whether or not that is an issue.

I think we all share your pain, but these escs are essentially 3 separate amps for the 3 phases, plus either sensored circuitry, or back emf circuitry. So quite a challenge. Hopefully some progress is in store, and/or the chassis guys will give us just a little more room. The wires alone must come close to the weight of some of the old brushed ESCs.

But I know I'm never going back.

Sweet. As a Tekin fan from way back I can hardly wait for them to be released. Hope it goes better than the R1 release, that seemed to take quite a while.

Ko Propo's BL ESC will most likely be the smallest in the market when it comes out. its roughly the same size as the old VFS-2000 units.

Technology just needs to advance. There is already one advancement by AMD, which allows them to make circuits 50% more dense by using light. They said by 2010 there should be processors on the market using their technology.

The AMD progress might help on the sensing side, but I doubt it could help the power portion of the ESC.

Yeah but maybe it will mean our brains will be directly wired to the transmitter

attached a pic of my esc that I made in the garden shed, it's small enough for me.
