Thanks again :thumbup: ...will keep an eye open for further threads... some of the terminology is over my head right now as I don't have a good working knowledge of the parts available.....right now I have a few helicopters in my junk yard... so salvaging parts from those would be the first step...the servos are really small on some..something I find ideal for saving space... so by watching you all... I might be able to somehow put the micro servos to use ;)

Video of my proportional turret setup. Sorry my filming is not better, I was using my cell phone. At full speed I was able to do a full 360 degree rotation in around 1 second flat.

More to follow, including how to reconfigure a servo to run continuous in either direction.

Hey Bulldog...you have any idea what's the max rpm on one of those servos

ALPHA,

After the multiple stages of reduction its down to around 240-250 rpm max, but it has a crazy amount of torque at that low of an rpm.

That's not bad... Have an Idea to use some for primary drive systems... ;)

IR battling...
360 degrees/sec turret rotation combined with super-spin that's some mortal-kombat-fatality-flawless-victory shit :D

ALPHA,

I was considering that as well. Be careful, some servo's are not continuous duty and thus cannot be run continuously. Find one with a good heatsink, with fins if possible. Heat builds up quickly.

Thanks for the input Bulldog... used to fly RC planes...but the systems have changed a lot... so I have to re educate myself to what's available ....have several designs running in the back of my mind .... most using conventional methods though... once I sort through things... I can finally put it down on paper then execute the measure ;)
