Thanks for the positive responses, I'm determined to get it done this time, and I'm shooting for our next battle day as a completion date. April 12th.

The WSN lower has enough room to accommodate the Tamiya electronics comfortably. I built two small .080 styrene boxes that were fitted and keyed for snug fit for the DMD and MFU. I'm using the stock gear box container with Tank Toko metal gears added, and there is still plenty of room for the battery. The only part I haven't got totally engineered is the gun movement.
