DX5e mixing...

[duff]

Here's an odd one, not a huge problem, but I would like to get to the bottom of it if possible. when I hook my motors/servo up to my receiver and use the old style tank steer (left stick forward-left wheel forward, right stick forward right, wheel forward) my motors/servos work fine.

However, when I turn mixing on, driving with just the one stick, as most of you do, and push forward, the motors/servos only go forward at half the rate.

Has anyone come across something similar and is there anyway to solve it? I don't hold out much hope as I shouldn't have cheaped out on my radio gear, but the DX6i is just a bit too pricey at the moment.

I'm not sure how much this will help, but here are two possibilities:

1) I was testing a single motor, controlled through one side of a sabretooth 10a. I only had the forward channel plugged into my receiver, and the on board mixing switched on. When I had the elevator pushed as far as possible up, the motor only managed half speed forward. When I pushed the stick into the top left corner, the motor went at full speed. I am not sure why this happens.

2) Much more simple. Have you checked that the rate switch is set to 'hi'? Setting it to 'lo' limits the motor/servo speed.

Hope this helps.

Yeah, it's like you said in number 1, when i push it to top left i get full speed on the right motor, but then the left motor goes off. when i push forward and right i get full power on left motor and none on the right. but forward centre just gives 50/50 on each motor. surely a mixer should give 100/100 forward when you push the stick forward?

Have you tried calibrating the speed controller with the transmitter on the new mixer setting?

[duff]

It's an electronize so im not sure about how much calibrating i can do. Plus i'm not sure what help that could give. the transmitter is only giving 50% rate when pushed directly forward. it seems like you can't get more than one motors worth of power from the pair combined when running through the mixer.

[leorcc]

Right, forget the calibration, Electronizes can't do that.

The Hi/LO rate is on hi?

[duff]

Yeah, it's on high rate. I kinda think it's just the way that the mixer is set up on the DX5e, you can't set rates so you have to live with defaults.

I tried the setup on my T6EX and all was fine.
