Making the 450 move around, especially on a delicate slope becomes a little more complicated having to operate two chs now with two sticks as well, if the boom is assisting in the move.

And whatever esc for the swing, preferably something that either has or can be programmed with a "soft" brake & smooth acceleration.

Lil Giants,

I am building a lattice boom crane. I don't know a great deal about RC controls. You mentioned "Soft start & smooth acceleration" on the ESC, what would you recommend for controlling a crane with two crawlers (4 motors), slewing gear and three hoist and maybe lighting or sound?

The motors I am using are DC gear motors. I have been controlling these types of motors with a wired PWM circuit. Radio control is just something I haven't learned about. Figuring out where to install such components would be very helpful at this stage of my build.

Thank You,
