1. when you say metal gear box installed by Mato, is that Zinc or Steel gear box?
2. also, would you be able to install Tamiya battle system?
I have no problems adding bits and pieces but electronics eludes me.
3. assuming tracks are plastic?
4. is HD camera like a GoPro or integral in the tank and controller?
5. speaking of controller, is that part of the package?
Sorry to be so anal but I need to cover all my bases.  Thanks

Hi ,
1- When Mato-Mart sells their tanks they exchange the stock plastic gears with zinc gears to extend the operation life of the tank.
2- To utilize to Tamiya Battle system  ( available at additional cost as noted  ), you would need to install the Clark board . While this is not a complicated procedure I do not have the time to do so myself. Having said that there are members that are very good at this.
3 - The tracks are plastic and perform better on the battle field. I included metal drive and Idler wheels if you chose to go with metal track.
4 - The included camera is an interictal, on board version ( sold by Banggood.com )
5 - The Clark board is the controller for speed, sound, turret motion barrel elevation and all other features. As mentioned in my ad this is included in the package.
 So basically the is an off the shelf HL tank with a good selection of extra stuff.

Excellent.  Thanks for the details.  This sounds like a good deal since Challenger 2 tanks are Sold Out at Mato.  I have a virgin Challenger 2 that I bought a few Years ago from VietRC when I went to Mississauga and have not made any modifications YET and this one would be a better fit for battles in KW.  How can we get together to finalize a deal?

I'll PM you ( in the " MAILBOX " ) so we can work out the details.
