Dozer control question.

[cosworth34677]

OK I'm working on a dozer and keep at the point where I am going to put the electronics in it!
So the thing is how would I mix the servo channels? I want one of the sticks to control the up and down of the blade and the other to control the tilt of the blade. I know it could be mixed on the radio, but how would you go about it. I have the cyclinders on there own valve .
Or should I just use one stick on each cyclinders without mixing? I don't know help!!!!

Thanks
Vic
