RC Liebherr A 900 C Litronic part 2 - Linear actuator test 1

In this video I take a look at making some linear actuators for an RC excavator. I use the same idea from the SIKU Krampe half-pipe trailer build to make a linear actuator from a brass stand off and some threaded bar. In the end it would appear that a 30 rpm n20 motor gearbox is too slow so I've ordered a couple of different n20 motors with different gear ratios so that I can test each of them to find which is best for a homemade rc excavator The forum topic on this build can be found here: http://rctractorguy.com/forum/topic/r...
