if there is room an idler will adjust the slack.Thanks guys, I am enjoying it!!
My Warner actuator is moving 2.5 - 2.7" per second. It spins that fan around in a hurry, that's for sure! It is a little jerky, but from what I can tell it is due to slack in the chain itself. I have it pulled tight with the sprockets, but the chain itself has play in it when changing direction. It's not bad, and the DC adjustment will fix it.
That DC controller wires in up front by the joystick, so it shouldn't add any clutter under my platform.
