1/25 6 Axle Lattice Crane

[Southgate]

Progress report...I ordered that BaneBots ESC, installed it, and watched as the crane's upper unit can rotate at high speeds, and definately has improved lower speed performance over previous ESCs, but still can't run the motor smoothly at the required SUPER slow speeds. I put it into my box of RC stuff. I think it will work fine for wheeled speed control, but for ultra smooth-slow speed, I'm still having to use the servo turned train throttle mechanism. I do acknowledge that what I am asking of an ESC here is probably well beyond their intended purpose. It will no doubt find it's way into a future project, or it might be useful even on one of the crane's existing applications. At least one real plus is it's compact size, and the price was better than any other reversable ESC I've ever seen.

what kind of radio ? I'm not sure of the term , I think it's trim If you go to the channel you have your swing motor on there is epa ( end point adjustment ) start reducing the % this should slow it down . found this out yesterday when I could not figure out why rev. was slower than fwd on my tractor . what ever fwd % is set rev % the same .

Perhaps you may need to get a motor with more reduction in the gearing. What are you turning now? Like Steve said too adjust the slow starting of the radio. I didn't know those radios were capable of doing that. That is a cool thing to have. One thing I have noticed on these trucks on here is the speed is right now and same for reverse,no pause to ramp up,not too realistic. On my machine,my 90Volt drives can be adjusted in many ways including ramp up and down speed 0-20 seconds ,torque output min & max speed. My swing is too fast so I have it cut back the speed and the ramp set so the bucket is not swinging back and forth making everything more controllable.
