Upgrading 27 Mhz Heng Long Panzer 3

[DorkVader]

Hi!

Beginner talking here so try to bear with me. I have some experience with RC cars but not so much with these tanks yet. Sorry if I am asking something that is answered already somewhere, but didn't find enough info.

I just purchased a couple of old Panzer 3's with 27Mhz systems but they had the same crystals so I was about to buy new crystals, but then thought that it might be better to upgrade the receiver to newer model.
From some thread I found this package: https://www.banggood.com/7_0S-Functi...p-1476236.html

Do any of you have any idea what else it takes to fit this to the old models? Will I need to redo all the wiring or purchase other modules too?
Can I upgrade also the IR system for battles after this?

The newer 7.x systems are far better than those old 27mhz ones in features and better driving characteristics. If you can solder and/or crimp JST and Dupont connectors then you should be OK, but it is an extensive rewiring. There isn't really a conversion manual or anything so it will be a learning experience if you do it. The 7.0 system no longer uses a daughter board, but the connections from the daughter board are now direct wired to the new control boards. The 7.0 has the newest version of the IR protocol and it can fight with Tamiya, other HL 6.x/7.x, TongDE 3.0, and Torro tanks *if* they are running the IR protocol converter board. The old 27mhz system used the old HL protocol and can only battle with the old HL tanks prior to the 6.x systems.

I have upgraded a 2005 Heng Long Snow Leopard (M26 Pershing) from 27Mhz RC to TK5.3 to TK6.0S. I give HL credit for keeping their RC tanks physically and electronically compatible over a 20 years period. You can find the lastest chapter of my journey in this thread.

The wiring got simplier at each upgrade step:

There are four motors in a typical tank; left and right treads, turret rotation and gun elevation. Armed with the wiring diagram of a 7.0 board, rewiring them should be easy. The diagram come with the board, and are available online too. As Tank Me said, soldering, crimping or splicing wires is all the expertise needed. One more circuit to modify is the on/off switch. Getting the gun to fire and adding IR capability takes more wiring, but if you successfully managed the above steps, the rest is easy too. You will need to buy plugs to insert in the 7.0 board, but those are available on Amazon, or other electronics outlet.

If you plan to upgrade the electronics, it's best to remove all of the old wiring and start fresh.

Now here is the caveat: the new tanks are so inexpensive that by the time you buy the board, wires and tools you need, you won't be saving much. Also, old plastic does get a little brittle, potentially cracking or breaking. This isn't meant to put you off your project, the work is fun in itself!.

In fact, doing the electrical and metal upgrade piecemeal is much more expensive than buying a professional version Heng Long tank. The upgrading process is a lot more fun than just running the tank. It may not be for everyone.

The RC tank is one of the simplest and less expensive RC toy for adult hobbyist.

I have just bought 2 Panzer III tanks for my club at $140 each. They have metal tracks, sprockets, idlers, and gearboxes. I am replacing a couple of the worn-out loaner tanks we used for 2.5 years at our club's event.

Need help I have a question, Can I use the 7.0 remote to control the 6.0 board? I have 3 of 6.0 tank but 2 remote is broken and I only have 1 left. And now the 6.0 remote is no longer available.

No, 7.x only works on 7.x systems and 6.x only works on 6.x. But...this remote works with a 6.x system:

I know for sure it works as I have one and I have bound it to a 6.0 system.

The price of this CanShue 6.1 transmitter may drop fast since there is no more TK6 receiver on the market. Do they make a 7.1 generation transmitter?

Any way, it is more prudent to invest on new TK7 receiver than on new TK6 transmitter. Yes, it is a costlier investment, but a better long term one.

Not that I know of. The CS transmitter is also used on the Haya 6.3 MFUs which came installed in my Chieftain. That's where I got mine. The Haya 6.3 is basically a Heng Long 6.1 as it has two servo ports.

Just as a stopgap measure, if you're not already aware, you can bind all 3 6.0 tanks to one 6.0 transmitter.
Step 1: Both tank and transmitter are off.
Step 2: Power up the tank.
Step 3: While holding down the "ignition button" on the transmitter, turn it on.

If you did it right, the sound will come on and it's ready to drive. And yes, you can have all three run at the same time off the one transmitter! Choreography will be up to you.

Thank you -keilau,SoCalBobS,tank_me for your answers. It's a good idea.
