| Details for building a 1/6 Scale Radio Controlled Tank. | ||
 | Having
been inspired by Marks Tanks at
http://www.cyber-innovations.co.uk/mark-1-tank/ and the construction ideas at I have decided to try my hand at building a 1/6 scale radio controlled tank. I have chosen to build a British WW2 Cromwell Tank as it makes a nice change from the normal German favorites and I don't want a tank someone could just buy [ they may compare it with mine !] Left is both a drawing and a Photo I haven't decided on a Mark yet but a latter derivative the Centaur is quite appealing as it has neat Turret Markings for it's close support role. Once I had decided on which tank to make I looked for references that gave Length Width and Height to work out how big a 1/6 scale Cromwell would be. I then found a drawing which I scanned at 600 dpi and used a poster program to print the drawing out at the required scale. I then spent a happy couple of hours cutting and gluing 45 sheets of A4 together to get a working drawing. | |

No tank is ideal and this one has a couple of bad points:- The tracks are narrow which means they are harder to make and harder to make strong. The body is quite wide [good] but not very high [bad] but I am not going to worry over much if I have to adjust it a inch here or there , anyone seen approaching with a tape measured will be fired upon ! My construction will be based on Steve Tyng methods and his T34/85 can be seen here. http://www.rctankcombat.com/tanks/T005/
As you can see my Workshop/Garage is somewhat cluttered and I can still get 2 cars in on a night ! The chipboard tank prototype is sat on my saw bench and a Electric Golf Caddy is sat up in front of the saw.
In the UK there are few Surplus outlets that the American/Canadians have access to so the best place to look is the Council dump [ Civic Amenity Site ] as they are allowed to sell any items that pass through and I have found a couple with what the Yanks call KCM's [ Kiddy Car Motors ] basically a RS550 Motor with integral gearbox that can propel a vehicle and Child/Small adult at around 4-8mph This Quad cost me all of £5.00 it looked worse in the flesh but it was able to move about 10 yards when I fiddled with the wiring , it had been outside for a few months and so the switches were rain damaged and the wiring had been attacked by some Neanderthal ! It would have been £10.00 if it had a battery and a charger with it. It was over £200 pound new !
This was a £5.00 motor bike a good buy as it was 12volt , don't buy 6volt vehicles unless you only want the gearboxs and can source RS550's at 12volts they won't have the required power.
This was a electric motor bike you can see the KCM's lying to the left of the wheel and they just key into the wheel.
These are harder to find cheap and are from a Electric Golf Caddy but the motors look superb and they are very quite [ the KCM's can be heard 2 streets away ! One of these powered me at 12stone [ 80 Kilo ] across my drive and across the front lawn with the speed controller making more noise than the motor/gearbox
This is inside the gearbox very well made , the only problem is that they are not handed [ unlike the KCM ] so it makes them harder to mount. Most electric motors are timed so go in one direction faster than if they are reversed meaning if I mounted one upside down and reversed the connections the tank may go around in circles ! We shall see.
