Heng long 6.0 Challenger 2 upgrade (Part 3)

here is part three of my video describing all the updates and upgrades made on my rc heng long Challenger 2
A few people have asked me how to do this kind of work that I have been doing for some time on some tanks that I built in fpv, so I decided to make some video for the whole community to see.
It is clear that more upgrade videos will come out later.
