    you could just get a v tail mixer there not expensive, i use the cheap ones and havent had any problems but i dont use the tz85 esc

      You can't directly measure the voltage out of an ESC as they don't vary the speed of the motors with voltage they vary it with switching. So they pulse the motor with full voltage at different frequencies to achieve the equivalent power input. So no matter what speed the motor is doing the voltmeter is reading full battery voltage being switched between 0 and full constantly.

      I have one of the older DX6i's but I've not seen this problem before always getting 100% output in turning or forwards/backwards!

        Been doing some research into all this. The only way to get proper mixing like you'd want on a bot would be to use a Spektrum DX8. The Hobbyking set is a bit better in terms of the mixing.

        I'd love to use a v-tail mixer but dont people have issues with them at the higher ends of their throws like Ellis said?

          Yes and no. In our particular setup, with a Planet T5 tx and rx set on one side of the mixer and the tz85s on the other, it so happens that it's not perfect. But it isn't what I'd consider an issue, at all. I have never noticed the oddity in the arena across the 30 odd battles Tormenta 2 has done.

          We didn't get it from this seller, but this is the model we have: http://www.ebay.co.uk/itm/GWS-V-TAIL...item20c29a50cf

          In Tormenta 1 we ran an identical setup to the one we have now, but with Electronize instead of the Botbitz, and the oddity wasn't there, so chances are it's something that can be fixed anyway.

          For at most 10 quid, it's worth a shot?

          Edit: as for "don't people have issues..." I can't speak for others, but I don't think this is a common problem with mixers.

            i haven't had any noticeable issues yet with the v tail but again i don't use the tz85


            this is the 1 i use (might be worth testing before you spend a load of money on a new transmitter)

            but some people prefer GWS v-tail mixers

              cheers guys. Funnily enough, i have both of them already. Will have to spend an afternoon giving them a go.

                didnt work! I'm having a closer look at these hacked Tx sets (http://www.overkillrc.com/gt3bfeatures.htm) but the hobbyking set will do for now. thanks again for all your helps guys.

                  Hi Dan

                  I'm having the same problem with my Dx6i and TZ85a's. As far as I know the issue is something to do with the program on the hacked ESC's and them not being able to interpret channels mixed in a certain way. It might have something to do with the RX your using. I've got the cheap Orange RX's but I know people running exactly the same set up with an AR6110 in place of the Orange didn't have any drive issues at GSL.

                    The problem is that when the input signal to the ESCs goes above 100%, they shut down. This is programmed in and I've contacted botbitz to see whether this could be changed. If you use the elevon function and those mixes for 100%, it sends the signal to its max possible value.

                    I've got both those receivers and neither makes any difference. Will keep working on it.

                      Very simple, only complaint with the tz85s I suppose is that when you put the stick fully into a corner of its travel, it doesn't move. I assume this is some sort of mixer+tz85 combined issue as it didn't happen when we used to run electronize.
                      I noticed this problem as well, using a mixer which I am assuming is identical to the Turnigy one posted earlier (got it from GiantShark). Tony and I suspected it to be the mixer that was the issue as the same problem occurred in the small kits we ran at GSC, but if it's happening on the GWS mixers too, then I would assume it's something to do with the programming in the ESCs (incidentally, the small kits mentioned were running BotBitz 10A units).

                      While it may not seem to be a major problem, it does mean that you're not able to command your robot to turn around one wheel at full speed and if it cuts out instead of this, it could be a split second action that affects the course of the battle.

                      Will mess around with some other mixers and see what the results are.

                        Having the same problem. Using a DX6i with orange receiver. TZ85a with hacked software. Spotted this when benchtesting my bot.
                        Agree its an issue in control of the bot and it needs to be more precise
                        Havent had a look at the software to see if it can be programmed out

                          Had a quick look at code and the calibration software still seems to be there.
                          Away at present so havent been able to check but have a look at the tz85a manual
