The Tank featured here is one of my most prized models in my large collection. I say "one of" because I have more survivors from this time period that still operate and a few that are beyond repair (see avatar)
I assembled this Tank in 1978 with the hope of making it Radio Remote Control. At that time, Radio controlled toy grade cars started appearing at the Mall stores. There was no internet at that time and the local Malls featured the latest Tech available to the masses. That is when I started to notice these RC cars. I got the idea that I could use the radio gear in my model tanks as there were relatively inexpensive compared to the HG radio gear available at that time at Hobby Shops. Being a young man at that time I did not have the money required to invest in a HG radio control system which at that time was geared towards Nitro powered Radio control Planes and ESC's were not commonly available anywhere. These TG cars seem to be the answer. So that was my plan for this FLAKPANZER.
I was 21 at this time and had some electronic training under my belt and thought I might try my first "radio control tank build"
So I bought this Tamiya FP VI at the local Mall Hobby shop and after getting it back to my primitive work shop decided to assemble and paint the model and save some money to buy a Toy grade RC car. After some time, I snagged a 2 channel DP Radio control Van and played with it a few days and totally enthusiastic about using this radio gear in my 1/35 scale Tank
So I removed the screws from the bottom of the Van RC model and marveled at what I saw.....The most high Tech thing that I ever had ever seen! 
more later
in the mean time, here are a few pictures of one of my first model tank builds 44 years ago. I add more of the story and pictures to this post as time allows.
