Turnigy TZ-85A brushed motor hack - amended code for Spektrum Dx6i

[Danjr1]

Hi all,

Following on from the amazingly brilliant open source code created by Aaron Knight and Steve Martin at Botbitz to convert Turnigy TZ85a ESCs from brushless to brushed motor controllers that a load of us have used, a few of us have experienced issues using this code relating to the Spektrum DX6i's internal mixing when measures are implemented to facilitate 100% throws in all directions as opposed to the stock elevon function that only allows 50% travel in the forward and backwards directions. This is due to this mixing set-up causing the RC signal to go above 100% which causes the hacked ESCs to failsafe. There have also been issues with the temperature limit kicking in too early and failsafeing robots as well.

With a massive amount of help and guidance from Kane, John from Team Beast and advice from Aaron and Steve on the robowars forums relating to the temperature limit problems, i've been able to adjust their open source code slightly to compensate for the DX6i's weird mixing and turn off the temperature limit. This code is attached below. Using the botbitz tutorial to install the code, both Team Beast and I have tested the code and it worked for us but if you intend to download, install and use it, this will be at your own risk and I take no responsibility for any damage caused by its implementation. I also cannot guarantee that this code will work for you either. Below are the two set-ups that its been tested on so far:

My set-up: DX6i, Orange Rx 620, two ESCs running four gimson 18v 24:1 gearmotors on 6s
Team Beast set-up: DX6i, Spektrum BR6000, two ESCs running two speed 900s on 6s

I would like to take this chance to really thank Kane, John, Aaron and Steve for all their help in solving this problem as its really been bugging me for a long time, and especially thank Aaron and Steve for creating the code in the first place. Below are some links relating to the TZ85a hack:
