RC Tank Warfare community hobby forum

I recently got a Vs Tiger and Sherman from a member here and after evaluating these very detailed machines, decided I wanted to do a Heng Long 2.4G radio swap. I prefer the simpler control of 2 stick control with true proportional control Vs the 3 button stepped control of the Vs Tank Transmitter.

I decided to upgrade the HL board so that it has main gun up\down elevation. The HL 1/30 scale Tanks do not have gun elevation, well, they do but the left off the TC118S motor drive chip and the connector. So all that is needed to add this function to the circuit board is to solder on the motor drive chip and its associated connector. These chips are readily available from ebay. In the pictures and video below shows the work done to add this function.

Here is a video of the main gun turret drive upgrade. https://youtu.be/WtcY99epyaI

So with this mod the circuit board provides main gun up\down along with main gun left right, fully digital proportional control on both.

Note. The Tiger 1 Tank of this thread is not an IR Tank. It is a special model with bright gun flash from the barrel. It is being modified using Heng Long 2.4G IR battle tank Receiver board from a Heng Long 1/30 scale Tank. I like this HL circuit board because it ia small and easy to add to most any size tank from 1/35 scale up to 1/24 scale depending on the motors used. It is designed for 130 motors but can power bigger motors if the amp draw is 2 amps (peak) or less per motor. The Vs Tank of this thread has larger motors but they are designed to run off a higher voltage so with a 1 cell lipo they are within the current limit of the driver chips on the HL circuit board.

Oh thank you PW. I am a retired electronics professional and use this hobby to stay in touch with that skill (on a hobby level).
I am close to having the Vs Tiger 1 converted to Heng Long electronics. I will post pictures of my progress asap. Delay in the picture email system as of now.

A few pictures of the converted Vs Tiger 1 below. I will be doing the same work to the Vs 1/24 Sherman. In real life ww2, the Sherman could have fought the Tiger although that would not usually be a good idea for the Sherman. I think the ratio was 4 to 1 and in some cases multiple Shermans could get the best of the Tiger.

I am also going to restore the gun recoil system of the Tiger and I may also get the brilliant muzzle flash flash system to work as well.

Fot me I will have 2 of my favorite tanks from ww2 in 1\24 scale that can do IR battle

Bravo, Modler! Those tanks are in good hands! Will there be a chance at a video when you have the two battle-ready?

Certainly. It is taking longer than I thought it would. The Tiger is ready for field testing at this point and once it is working good I will start on the Sherman.

The Heng long circuit board I am using has the capability for main gun independent up\down function on the Tx but a driver chip needs to be added to the circuit board for that to work. I ordered some of these driver chips from ebay and will now upgrade the other 3 circuit boards that I have.

Edit added 6.8.21
Turret upgrades on this Tiger 1....
Main gun has independent up\down, left\right features both with proportional speed control.
Heng long I\R battle system added with IR emitter\detector. Machine gun LED.
Future work on turret will include, Muzzle flash, Main gun recoil, life counter\scoring LED display (4 LED array).

The Vs Tiger 1 tank came with a "brilliant muzzle flash kit" and main gun recoil but to implement these features will take a bit of electronic interface work to be able to work with the heng long circuit board. I have decided to do this work at a later time as the project is running long now and I want to see some results NOW.

The Vs tank conversion is complete. This is now a Vs tank with Henglong IR battle system with proportional on every channel.

In the near future, will get the main gun recoil to work with muzzle flash.
Next I will convert the Vs Sherman so it can battle the Vs\HL Tiger.

Great to see someone modding the 1/24 Vstanks! I give up trying to find metal tracks for my VS tiger 1, so I swapped out the gear boxes, sprockets and tracks with ones from a 1/16 T-55 hooben tank. It will be my FPV garden basher.

Dear Modler,
See your post of this conversion is so impressive, I also want to do my own 1/24 VStank tiger too, can u share the gun elevation mod what electronic component part of the 1/30 HengLong RC board needed to add and solder from the picture? what is it and can I buy from web? Thanks much!
