Hi everyone, I'm building a budget featherweight but I'm having some trouble with the steering. I got two esc's (Turnigy) from Ellis and i have a cheap transmitter and receiver.
So to get the tank steering i wanted i ordered a Mtroniks V-tail mixer but it has resulted in me only getting forward and reverse.
I've tried many different channels and swapping wires around but still no luck.
Also I'm going to extreme robot in Manchester (first combat robot event ever), I got the VIP tickets anyone know just how VIP VIP tickets are???

Can you do a rough drawing of how the receiver, V-tail mixer and ESCs are wired together?

This help? 17409858_1458484097503907_445182126_n.jpg
I tried it on multiple channels but still no luck.....

Its a bit hard to tell exactly how the receiver and mixer are wired but it looks generally correct (and very neat!). So you get equal speed forwards and reverse on both motors? Is that the case when you move either the throttle or the steering on the transmitter? If the mixer leads are plugged in to the receiver throttle and steering channels, then you *should* be getting full control.
Maybe the issue is with transmitter - any info on that? At this stage, it could be that you are not getting any signal from the steering, just the throttle.

Ha ha thanks, messy wiring really annoys me.
yeah equal power is applied to both motors for forward and reverse but nothing when being asked to steer.
here is a pic of the receiver and mixer(channel 1 and 2), as well as my cheap ass transmitter.17392147_1458553674163616_1462243986_n.jpg17439828_1458553600830290_785911496_n.jpg

OK, so you can rule out the motors, ESCs, the mixer and probably the receiver. If you unplugged the mixer from channel 1 on the receiver, do you get any control of the motors, or nothing at all? If there is absolutely no response, I would suspect the steering channel is faulty.
That radio is more programmable than it looks. If you go to the product page and click on the files tab, there is a configuration program and dozens of instructions to download. You also need a cheap USB cable that plugs in the trainer port on the back of the transmitter. I haven't tried it, but I believe that you can program the radio to do mixing and eliminate the v-tail mixer - perhaps somebody can confirm that? You may find via the software that your issue is just a badly configured radio, otherwise its time to get in contact with Hobbyking.

I was gonna say I've had this before and it ended up being that the transmitter was trying to mix as well as the vtail mixer. On some of the transmitters there is a jumper or switch in the battery bay that toggles mixing on and off. Check for that, and if no joy, as nick said lose the vtail and USB the transmitter to enable mixing directly.
