As you may or may not have noticed at Aquino... My eldest broke my Panzer IV's turret skirt armour, Schürzen (dastardly Evil children!).
It also stopped working for them with no explanation... (I had thought that I may have fried the Clark board in it). It had the magnetic upper hull mods, but still had the bottom access battery box. Since it was in for repair... Time for a Big Mike, reworking!
Ripped out pretty much everything except the motors. I did however drill through and bolt down one motor base as it was extremely easy to flex (stripped motor screw to lower hull).
Cut out the battery box, except for the front most panel. Put in the fire wall using the remaining portion of the battery box.
Added in a 3/8 square tube hull brace to the front firewall.
Glued the old battery cover in place, and resin filled the entire rear compartment to a roughly flush level.
Adding in a wood base for the clark board and acts as a battery stop.
Reused the old speaker in the exact same location.
Side mounted the receiver (Through holes along side posts to allow passage)
Added a fan above the Clark FET's, powered by the receiver
Secondary brace/battery guide and new power switch
Did I mention Wiring cleanup?
So the general overview of the finished PZ IV lower hull.
The wooden base for the Clark.
Double sided tape on the bottom of the HL MFU case half (Surrounding the Clark)
Receiver and antenna placement in the lower hull
The Fan above the FET's. I checked the board after and everything worked... Maybe the old power switch failed?
Wiring clean up in lower hull. Yes those are crimped connectors, in case I have to remove the switch... Soldering in such a small tight space would be a Pita!
Side shot showing the overall height of the components in the lower. There is an additional 15+mm above the lower hull edge internally, so lots of space vertically...
Shot from the front. Could only fit one motor Heat Sink on, but it will have to do.
