Looks like Henglong 6.0 works just fine for a casual tank battle player in many ways.
I have 3 tanks with Henglong 6.0 MFU right now, just for its low price and easy installation. And I'm ok with its IR battle system since I don't have a local club to battle with, its just me and myself. lol
However, I just found a pretty good aftermarket MFU on Taobao recently, it's about 90 USD for the MFU only. And according to their videos, it fit Henglong 6.0 board tanks(you don't need rewiring everything). Also, it controls and sounds as good as Elmod MFU. So if you plus that 90 bucks with a cheap 8 channel radio, which is about 50 bucks or so, you will be sitting around 150 bucks for something that performs as good as Elmod MFU.
