Not come across that before. However, the USB - micro USB cable they come with is crap so try another to see if its that. If that doesn't work, its most probably busted by the sounds of it.

Hey guys, can someone explain to me what the actual issue is? In researching this (these) issues ahead of buying some more BB-hacked TZ85s for Rango, I set up Tormenta 2 to run on the DX6i. At first, as predicted, the throws were limited when using the TX mixing and setting them to 125% didn't eliminate the issue. That was expected. I then did what the guy in the video suggested, setting the MIX 1 and 2 throws to 125% and I now have 100% fwd/back, correct mixing, and it all failsafes correctly, including the weapon channel.
The drive and weapon all runs on 3 TZ85s, and they're not new models, they were purchased sometime in 2012. But I seem to have correct performance. The speedos run out of range and brake the motors when pushing the stick into full corner, but that happened with our independent v-tail mixer and with the original Planet 5 setup.
What problem is everyone having with the DX6i/TZ85 combo? Doing the programming quirk in the last video on the OP seems to have solved the half rates problem. The corner stick not working is technically an "issue", but in combat you rarely go into that part of the range. And even if you do the moment it's back in range the motors run full throttle, there is no delay.
Can someone enlighten me on what should actually be going wrong here?
edit: actually it might not be mixing quite in the same way it does with the Planet 5 and separate v-tail but I don't think that's related to the speedos. It seems to interpret my stick inputs a bit differently. Yes, the corner-stick-cutout is a bit weird and might be a bit more extreme than with the other radio setup but it's a non-issue I think. Can't really know until I can drive the bot in anger, but, it seems it's only full throttle donuts that can't be done!
Question of whether my experience matches those of others with the same setup stands, though!
The speedos run out of range and brake the motors when pushing the stick into full corner,
I fixed this by reprogramming with the code below. Had no problems after or any special mixing on the DX6i

Yeah, same problem as I had, corner cutout. It was an issue in my eyes and it was something I was acutely aware of and which irked me when driving, rather than something minor that I could adjust to. All fixed with the amended Spektrum code (wasn't using a Spektrum though).
I don't have somewhere I can test properly to know if it's an issue for me is the thing. I am confident I can fight with it as-is if necessary.
Off topic but related question, how long has it typically taken for BB orders to arrive in the UK for you guys? Worried it's too late now.
Thanks Danjr1, i've tried an alternative usb cable I had from something else. It does the same thing so recon its busted as you say. Another one on order :)
Hi,
I'm planning on hacking some TZ85A, but before I order the pololu programmer I wondered if I could do it with one of these:
https://www.sparkfun.com/products/718
Which I've already got for programming arduino minis. Or can I use an arduino as a programmer (I'm sure I read about it somewhere?)
Thanks,
Max
New version of the BotBitz 85A available with a programmer box.
http://www.botbitz.com/image/cache/d...V2-500x500.jpg
Allows you to adjust the low, centre and high points on each controller to suit your TX plus other features.
If anyone wants to upgrade their V1 85A's, email sales@botbitz.com.
Well my programming cable arrived from HK (Atmel Atmega Socket Firmware Flashing Tool)
Programmed 3 TZ85a in less than 5 minutes - a breeze compared to soldering on the board
I've tried to set up mixing on my DX6i by following the video but I don't have wingtailmix as an option :( not sure why. Anyone got any ideas?

Its in Heli mode. You need to set it to acro mode which will then show the options you need.
Ah amazing thank you!
yeah just brought that push on cable and it has a 10 pin connector the pololu programmer has a 6 pin and the programmer which goes with the cable is out of stock now its just a case of cutting 10 wires and matching them up ?Quote:

I now have the push on connector that Adam had. When I reprogrammed his, he provided a 6-10 pin adapter that allowed the 10-pin plug to plug into the Pololu 6-pin plug and it worked fine. Ever since, I've not managed to get the push on connector method to work. It either would not recognise that there was an ESC connected or, more recently, would cause the ESC to go up in smoke :P (not sure if that was the direct reason)
is there any pictures so I can follow the wires etc so I can do a cut and solder ?

Using the push on block connector getting 4.4v ok but will not go into program mode any help thanks in advance
If any body going to the gaget show next week who has a programmer or push on block connector will they bring it please these are just for spares
Thanks
John
OK
I'm getting a little confused now, I haven't tried hacking these speed controllers but would like to start. can I have a list of equipment and/or software needed, and any information on the current procedure to do the job.
I'm not an electronics expert but if John can do this so can I. :)
Hi Craig,
The first post in the thread has a components list which has never really changed. It also has the videos which again haven't changed at all either. Only thing that's been updated is the ESC programming software but you can still download and use AVR Studio 4 which is shown in the vids. Its scary the first time you do it but it literally is soldering 6 wires on, plugging it in to a power source and the computer then clicking some buttons.
Hi all.... just wondering if all this is still valid?? I have dx6i and about to order my tz85s from botbits. Just wondering if the software flash is stil needed to work correctly with my transmitter as this post was a few years ago.
cheers
It is still valid but you won't need to carry out the flashing if you're buying from botbitz as they come pre-flashed with more modern code.
Cool..., cheers mate
I've found that AVR Studio is a pain in the backside... I've been using AVRDUDESS (https://github.com/zkemble/AVRDUDESS) to perform the flashing. You could also feasibly use avrdude on its own from a command-line if that's your thing.
So far, I've successfully reflashed two TZ85A using the firmware in the first post of the thread (which works beautifully, btw!) and two F-20A using the original firmware from https://launchpad.net/brushed for them.
I also can't recommend the Atmel Flashing Tool from Hobbyking enough - it makes the process so much easier than having to solder wires to the board!
