So after running around a bit, the plastic dip is peeling off the tracks. Bummer, but expected. I am wondering if spraying the plastidip spray would adhere better. I would have to mask off the end connectors, ugh. I think I am just going with the plastic tracks.... Less drag anyway...

I installed the BARC4 and realized that the Tamiya Apple IR base I put in the turret, wont plug into the BARC, so luckily I had orderd a Battle Armor brand Tamiya apple mount that has the cable plug that fits the BARC, didn't realize they were different, so I had to remove the Tamiya brand mount and install the Battle Armor one. Take note of that everybody....

I hooked up the a servo Y cable from the elevation channel going to my elevation servo, and the BARC Gun input, and the gun servo to the BARC. I have a rate reducer from http://www.dionysusdesign.com/produc...roducts_id/192 on the elevation servo to slow it down, though it only does a little bit.
The BARC operates the recoil, the opposite direction of my servo recoil install, so it wants to push the barrel out of the tank. I had to get a servo reverser to fix this, and because of that, it moved the stop position or full forward, making my barrel pulled backward a bit from where I had it mounted. I had to remove my barrel and take the barrel recoil saddle off and rebuild it so that it was adjustable on the barrel so that the barrel length could be adjusted when the servo sits idle. I turned the screw on the link clip around and soldered it to the saddle and put a nut on the end. Then I drilled a new hole in the saddle and soldered a nut on so a set screw could be used to secure the barrel to the saddle.

Next I installed my flash LED and my IR LED. I was able to fit both of them in the Nick Aguilar 75mm barrel by filing off the flange of around the LEDs and fitting them in the barrel. I have the IR up front, and the Flash right behind it, painted orange. I filed notches into the sides of the flash LED so that the wires of the IR LED could pass through it as the LED bulbs are the exact outside diameter as the inside diameter of the barrel. This was tricky but worked. The flash was brighter before I painted the orange on it, but it was bright white and I felt orange was more appropriate. Its color and brightness is muffled a lot more in the 75 barrel than in the 105 barrel of my Tamiya. None the less, this worked fine and is quite visible.

Look close and you can see the notches filed in the Flash LED to allow the IR wires past it
My new adjustable gun saddle for the recoil

I am not sure how well I like the barc4 yet. The servo recoil is nice and accurate, fast pull slow return. But to fire the gun, you tap stick up left in the corner. Up right is the machine gun. Its much easier to fire the machine gun than the main gun because I use left stick drive right stick turret so the machine gun is my thumb pulling rather than pushing for the main gun. None the less though, most of the time if I am quick enough, My elevation servo doesn't move, even though its on the same channel.
