![]() ![]() So with this mod the circuit board provides main gun up\down along with main gun left right, fully digital proportional control on both. Here is a video of the main gun turret drive upgrade. In the pictures and video below shows the work done to add this function. These chips are readily available from ebay. 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. 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. ![]() I decided to upgrade the HL board so that it has main gun up\down elevation. Also when the tank stops moving the engine sound stops. Unfortunately no volume control of any kind. 27mhz radio removed This thing has a very nice speaker and is quite loud. Heng Long radio shown in lower picture works fine but is not compatible with any battle tank I have. the Heng Long radio is the same as used in this 1/30 scale HL M3 Sherman. Most of the connectors in both tanks are compatible. Was not sure the main motors from the Vs tank would be compatible with the HL board. HL radio installed enough to do a mobility test.

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 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.
