RRC = Remote Radio Controlled.

Don't know who makes it or where it came from. I bought it in a lot from ebay. Nothing in the lot worked and had been sitting a long time. I changed out the radio gear and rewired the motors in series so that its speed is more like a Tank instead of a Toy. The gun barrel is missing and I have no idea what it looks like but will try to come up with something. It came with two cells ni-mh but changed it to one cell with motors series wired with new U-Micro rx,twin esc.

Working on the original rx. It worked for a while then quit. It is so small that it is not fun to work on :crazy:

Sorry videos of this tank running were lost. Will update soon...

Sadly I don't know the size of that coin to help me picture how small this is.

And to be a tank, shouldn't it have a gun?

Yeah, always one complainer ;) :haha:

That is a US penny. I will get some measurements in mm asap. Yes the gun is missing. I just got it running after a week of working on it in my spare time. I will try to figure out something for the gun. In the mean time can you think of something I might use so that people in the UK could get an idea of its size?

are the youtube videos working in the links I posted?

It is a nice design as it comes apart easily with a jewelers screwdriver and is serviceable unlike most toys I see.

Good morning,
There are tanks that are even smaller, 1/144 scale but are not true RC. They use IR to activate their tiny motors. Manufactured by TAKARA a decade and over ago, their weakness was their tiny scale tracks. They deteriorated in almost no time and I had spent years looking for replacements before I called it a day. Tiny battery still charges and the Potato Masher Grenade handset still works fine...just no tracks. Mine was the King Tiger Henschel turreted design.
regards,
Painless

Good Afternoon :D
Yes I did mention in the title in capital letters RADIO CONTROL tank. IMO IR remote control is a different category. The rubber tracks on this tank are in good shape and seem to be quite robust. I estimate the age of this Tank to be 12-16 years old.

Well, I do not smoke and do not have a lighter anywhere in the condo. As a former smoker, I can not stand the smell of cigarettes or any tobacco. So Have to think of something else. I know mm measurements work..

Good afternoon again,
Understandable, hence my lengthy explanation. Have fun with the little Panther ( Looks like a Digi-Q model one ) Those tracks are not scale and should last unlike the almost paper thin and realistically detailed ones of the TAKARA models. ;)

Painless

Painless, can't you use an appropriate sized elastic band?
Maybe draw the links on it?
Yes, I'm serious, I'm not making a joke.

Every serious model maker needs a cigarette lighter in their tool box, whether they smoke or not ;)

Yes, I can visualise the size now, thanks :thumbup:
