I've tried to research servos and the types out there. Not by analog, digital, etc., but what is available. For instance, my R/C tank that is a complete do it yourself conversion kit. I'm using a Heng Long 6.1s control module. I use a servo for the Main Gun recoil. There's a servo plug in for the turret rotation. This tank doesn't have a turret. I wanted to add a servo to open the drivers forward hatch. The digital servo doesn't move when plugged into the socket and a 360-degree servo just keeps spinning. I'm looking for a micro or mini servo That will travel with the control stick moved left or right. All my other R/C tanks are Tamiya, so there's no help there. TYIA.
