1/6 scale R/C tanks

[ddskipper]

Just a couple pics of my Tiger 1 that i finished a few years back. Almost done with Tiger 2 and then on to the Panzer 4 in the background. Tank shop workers need to get busy, so many projects and so little time!

Field of Armour tanks?

[ddskipper]

Yes they are. They are easily improved and open to so much detail is why i like them. And compared to an Armortek prices i can build 2 of FOA tanks although i would some day love to pick one of theirs up to build.

Hmm... A 1/6 Field of Armor Sherman with a plow on the front. I stand in the garage and plow the driveway in winter via radio control. Hmm... In fact, is that such a bonkers idea? How much power do those beasties produce?

From FoA.

The 450W motors, 3,000 rpm @ 24 VDC, 78% efficiency, coupled with 7.18 reduction gears and 13/9 ratio chain gears provide sufficient torque for driving and turning in rough terrain.

These motors I believe are XYD-16 24V 450w DC Brushed Motors.

So twin 450W motors equate to roughly 0.603HP. That is about 1.43 N.m (12.67 lb-in) torque @ 3000RPM. Add in the 10.37 :1 overall ratio and sprocket torque would be roughly 14.8 N.m (131.4 lb-in) per side. All depends on the sprocket pitch diameter.

An example would be for a Sherman tank with a Sprocket Pitch Diameter of 635.96mm (25.038 in). Scaled down to 1/6 ... 106.0mm (4.2 in). Each motor would give a tractive effort of about 14.8 N.m /0.106m = 139.6 N (131.4 lb-in/4.2in = 31.3 lb)

These are the motors below. I use the same ones in my KV-2 that was built in 1/6th scale for R/C paintball combat. The motors are quite powerful. My KV-2 weights like 120lbs and they will propel the tank above walking speed. The tracks are steel and weigh like 25lbs each. The gear ratios below are for the motors only using a 1:1 output ratio which is what I am using via 40 pitch chain drive so the final output shaft speed is 420RPM on my setup.

Superb Tiger I and growing collection !
You seem to be playing a bit rough with your tanks as i can see the damaged mud flaps and side skirts on the first picture in the field. There must be a not so funny story to tell about what happened.

Everything looks so perfect but I think you have mounted a longer Tiger II gun section on your Tiger I mantlet, any particular reason ?

Awesome beast. Be sure to post a video of it in action when you get a chance.

Actually just the gun that came with the kit, i believe it is supposed to be a KwK36 and i compared it to my Tiger 2 gun that came with that kit and the barrel and length are definitely a bit bigger.

Not sure if this will help but i run the same motors on 12 volts instead. Running time is longer but the thing i like best is the actual speed looks much more realistic for a R/C tank, also my tank will climb just about any slope with the slower speed control, and LOTS of power. LOL
