I think what you are describing is a gyro controlled turret. The turret direction is maintained regardless of the direction of the hull, It works on the same principle as a radio controlled helicopter, it's called a head and hold gyro. Barrel stabilisation works the same way. It needs switches so that it can be turned on and off from the tx.

Wow 350 kgs I thought my Tiger was heavy at 270 kgs, mine is also scratch built and I tried to keep the weight down but as its for the grandchildren to ride in it had to be strong, but easy for me to sync the turret just put a child in it :)

I've only just motorized the Turret though using car window motors and just cut part of the casing away to expose the large plastic cog to use as a drive wheel, 2 of them at the front of the turret using the weight of the gun and mantle too drive it while bearings at the back run around the underside of the deck, it turns at scale speed using a 7.2v 1200m pack, fitting a full auto BB machine Gun in at the moment by popular request (there goes another 3 day of my life just doing that) next the main gun @)

Any pictures of your Beast?

Not when you have 4.5 acres of land, Retired and now in South West France, when I finish build, if I live long enough, have plans for M1070/M1070A1 Tractor and M1000 Trailer to carry this Monster on.
Will put some pic's on when I get the Hull from UK, but for now making the odd bit's like the 50 cal, turret hatch's, suspension arms etc, and trying to find out how ime going to make it all work, hence original post Turret Rotation. Research take hrs and hrs.
Have a good Day in Sumter. USA

I'm just now seeing this, but Kevin Grannum did a turret lock set-up a couple years ago. Here's the video.

Hi Max, Thanks for your reply, video looks interesting, not watched it yet, thought i would thank you first, bought two GA250 on line so will start playing with these soon, at the moment concentrating on electrics etc, winter time development, now Summer is almost here can go back to the building part.
The hull is still in the UK, so have been making all the smaller parts like Capola, Tool box covers etc etc, the big project (and problem) will be the main Barrel as it's 4ft long and 4.1/2" in dia, Diameter not problem its the 4ft my Lath can only handle just over 3ft, can make in two parts and bond the two together with the metal sleeve for the 17mm ammo.
Any way bored you all enough so will watch you video, thank you again for your time, will post some pic's when i next have a bit of time. Regards to all. Mike.

This is one of those times when it's really too bad that there's all that water in between us, because my lathe can handle pieces up to 120 inches long. Well, technically it's not really mine, it belongs to the company I work for but I have access whenever I want. Having a fully equipped machine shop at my disposal has been a real blessing when it comes to building tanks.
