After some of the brushed Botbitz 85A ESCs (at least two but one will do). Out of stock on both Botbitz and Ranglebox.

Be happy to reprogram a few if hobbyking has them in stock if you fancy?
So Hobbyking are all out of these as well.
I get the feeling they have been supersceeded by the AE- models
80 amp version:

65 amp version:
https://hobbyking.com/en_us/turnigy-...hless-esc.html
The descriptions say...
"The Turnigy AE series are based on new powerful microprocessor.
The new CPU means ultra fast sync timing, crisper throttle re..."
But cannot confirm this. Im after 2 TZ85a but may need to look to see if these 'newer?' models are programmable in the same way...
I hope they continue with tz85a else need someone to port SimonK to these pronto !
Has anybody cracked open the AE series ones to see what MCU it uses?
I can't imagine they'll discontinue the TZ85 with how popular it is. The site page is still up, I bet they're just waiting for another production run.
Im tempted to get the AE version just to open it up... as i could use it as brushless controller if else?
Challenge accepted. I am ordering one today. If all else fails, gives me an excuse to reuse the Red Brick controllers I have laying around make a fully brushless machine.
snap, me too!
Speed controller arrived this morning, will attempt to hack and update later on.
UPDATE: And that appears to be a no. If there is a MCU around, it is either one I don't recognise or is there but the chip is on the underside of the red board, which is soldered on.

garh you beat me to it! yes it seems that ssome desoldering is required to program this board. i will be trying this later today and see what the controller is and do some electronics work to it, but currently, this is a no cannot be used at this stage.
As ocracoke states, the controller is soldered to the control board which is soldered upside down to the FET control board. Should be simple to unsolder so will update after lunch.
Otherwise i have one for a weapon assuming it is single direction - AE meaning Ariel vehicles - props only go one way!... then i can try use it for brushless drive - fwd and rev?
your choke (the black inductor square thing) on your PCB seems damaged - missing a corner, was that part of your unpacking? i would contact HK and say its broken...Quote:

If it comes to it, I'll make The Honey Badger 3.0 a fully brushless drive, I still have a pair of 100A Red Bricks laying around that would do the job as drive ESCs so no real worries here. Surprised though that the control unit is upside down here, seems a bit counter intuitive for cooling but then again, there was a thermal pad covering the entire green side of the ESC so....
I forgot to add that Hobbyking have said to me that the Turnigy TZ85A are not discontinued, but are being manufactured by factory and Hobbyking expect to be restocked in 4 - 6 weeks time....
Well, if you don't want the wait, the single channel FeatherTwos are a good alternative ;) https://nutsandbots.co.uk/product/fe...ingle-channel/

In theory the following Hobbyking ESCs may be able to use the brushed motor firmware that the TZ-85a uses. I'm purely basing this on the fact that flashing the TZ-85a with simonK brushless firmware uses the bs.hex file so any ESC using this file might be able to be converted. Happy to be told I'm wrong though as I'm no expert.
HobbyKing 6A ESC 0.5A UBEC
HobbyKing 10A ESC 1A UBEC
F-40A
F-60A
F-80A
F-90A
If you want to give it a go, use this link to find out about the pins you'll need to be soldering the programmer to unless you have one of those flash tool pin things I've seen others using.

so this weekend i'm going to take mine apart and see what is going on under there, see if i can trace the outputs to see if it is actually pin compatible at least to the tz, meaning that if the code can be blasted onto it, i know that the pinouts will be the same and hopefully work...
May have to read off the HEX in case i cant get it to work, otherwise i will have killed it! lol
So long as it's AVR (AtMega8 essentially in most ESCs) then even if no existing SimonK hex file is appropriate, working out the pinout isn't too difficult. I did this for the new Red Brick PCBs before discovering that somebody had beat me to it - so if it is AVR based we can definitely get SimonK onto it.
By that logic, getting brushed firmware that can run it can be done by modifying the source for the existing brushed conversion software.
PS I have done this with F-20A to get them to run brushed motors so it is definitely possible!
Or just say F to it and get FeatherTwos instead ;)
I found this in the BLHeli documentation - the left hand picture looks like a match for the picture Ocracoke posted earlier in the thread. This is the same ESC by the looks of it, just the 45A version.

Following that trail I then found this for the underside of the 65A variant, for those not brave enough to take one apart:

Conclusion: it's SiLabs MCU based, and ultimately that means no use of the existing TZ85A Brushless firmware or SimonK, both of which are only Atmel AVR MCU compatible
