A blast from the Past! I will watch the videos a.s.a.p. Geepers, that thing is huge (and no doubt, so was the cat). It's a land-borne battleship!
Unh, how's the cat? Or shouldn't I ask?

cat is no longer with us sadly.
but yeah, hopefully i can get the build assembly right this year and with updated electronics to play with

gearbox specs and dimensions chosen for my FCM F1 is the JGY-370


rated for the 6v setup we have for our tanks and ordered it with the output shaft of 10rpm.
that may be slow but the design of the tank's driving sprocket is as tall as the hull. its quite large. so the speed should be nicely slow and torquey as the gearboxes are rated at 9kg at the shaft. i could pull a mato king tiger with that power. granted if the tank itself has the inertial mass to support it and not doing burnouts

for some visual aid on how slow 10rpm looks like. there is a website called gear generator and it gives a good idea how fast or slow certain RPM looks
https://geargenerator.com/#200,200,100, ... 0,0,3,-738
this one right here is set with the 10RPM in mind.

Gear Generator entertained me for a half hour the first time I clicked a link to it. I must restrain myself this evening.

told ya its a neat toy but a really good visual aid on how we can see RPM more accurately. there is also gear generator 2 linked in there. that version can produce and set up planatary gears

heres the gearboxes that i ordered. shafts are alittle shorter than i expected tho but i can fix that

Those are slick! They could fix many clearance issues!

Do I see that correctly: 6 Volt 10 RPM? These would fit just about any tank, but wouldn't it be slow going? (Me? I like slow going! I could see an M5 Stuart creeping along.) Please do keep us informed as to the where to get and how you modify these motors.

for my FCM it is a crawl cause also im not too bothered it being a slow gearbox because that speed is also offset by the humongous 81mm diameter sized driving sprocket.
since its a theoretical speed proposed was 20 KM/H, scaled down it should be travelling at the speed of 1.25 KM/H so really slow walking speed
