I used HL 1/30 scale 1s 2.4G IR battle system Radio in my first upgrade both M4A3, Tiger 1 Tanks. This works very well but the Sherman(M4A3) was a bit too slow for my tastes so decided to go with a HL 1/24 scale 2s 2.4G IR battle system Radio
in the Sherman and tune it to the speed I wanted which is just a bit faster than the Tiger 1. Both of these HL radios are compatible in battle mode with each other and the circuit boards are the same size and all the I\R components are compatible on a circuit board level as well as Battle mode between Tanks
Oh, and both systems (1/30-1s\1/24-2s) use the same excellent Transmitters!
Testing reveals that the Sherman now has the proper speed with its new 2s power supply lipo and the Tiger 1 as it is now with 1s system works very well as is so no need to upgrade the Tiger 1 as its speed is perfect as is
I upgraded both to HL 2.4G radio system initially and that was a major improvement but because of the drive motors being designed for 6 cells (~7.2V), the tanks were a bit slow with the 1 cell lipo radio system. So after some time I realized a phase 2 upgrade was in order.
This thread will be about the phase 2 upgrade with 2s lipo using a 1/24 series HL radio system. The new radio system for the M4A3 Sherman comes from 1/24 2s HL IR Leopard 2 Battle Tank. This is a very compact and robust radio system that is ideal for 1/35 - 1/30 - 1/24 IR battle tanks.
I will post pictures asap, just wanted to get something up now as I am working on the project.
This Sherman features:
IR battle system with 4 hit LED scoreboard.

IR LED in the barrel for precise aiming
Variable speed Turret traverse L\R and Barrel U\D
concealable U\D channeled IR energy detector (requires opponent tank precise aiming to score a hit)
Track recoil with Gun recoil
Proportional speed F\R with track spin L\R
Precise\smooth gearbox operation
Full suspension with durable ITL tracks.
Scale functional headlights
Multi stage diesel engine sound, Main gun, machine gun with volume control from TX
Start\standby via TX. Headlights blink when in standby.
