RC Tank Warfare community hobby forum

Hello everyone, my name is Marc and I've been in this hobby for about six months.
My first tank was a 27mhz Heng Long Tiger I that I upgraded to TK-7.0.
The next one is going to be a Sherman from Heng Long updated.
A greeting

Welcome! I just did a similar upgrade to my Challenger 2. That upgrade from an old 27 mHz board to TK-7.0 is a bit of fussy work, requiring a change-out of connectors. Clearly you are fearless about diving in. What plans do you have for the M4A3?

Hello and welcome from Argyll and Bute.

Hello and welcome to the forum

I do like a Sherman or two, great little runners

Welcome to the group Marc.

M'mmmm Tiger...

Hello everyone again. For the M4A3 Sherman, for now I’m just planning to replace the plastic drive sprockets with metal ones. I bought it second-hand at a good price. It comes with metal tracks but not metal sprockets, which I don't understand. I’m wondering if the gearbox is metal or plastic.

Welcome from Ontario, Canada!
That's a great way to build a fleet. Buy them used and upgrade them. I have 10 tanks, only 3 were bought new, the rest are fixer uppers...slowly getting fixered-uppered and modernized electronics.
You'll be changing out MFUs in your sleep pretty soon!

Mike.

"I’m wondering if the gearbox is metal or plastic." If you upgraded your Tiger 1, you will find it easy-breezy to open up the Sherman and take a look. I would be tempted to upgrade the idler, too.

Since we are in North America, we don't have all the ready resources people in the UK, Europe and Asia enjoy. However, here's a seller with lots of parts: https://www.toucanhobby.com/search?q=Sh ... ix%5D=last
and another with lots of goodies from Torro/Taigen and Mato, some compatible with HengLong (ask here on RCTW if any is of interests): https://www.motionrc.com/

There are also two types of metal gearboxes...the dreaded sintered Chinesium ones and the steel geared ones. If you put a magnet on the gears, you will know if they are steel or Chinesium. The Chinesium are really brittle and very loud.
