My brother was lightening it last night while I try and fixup the electrics. Therere may be space but we dont have the weight. He lost 1.5kg, only another 2kg left. Mind you when we started the base plate on its own was nearly 20kg! And it doesnt help when the valve is nearly as big as the ram.

Using the IBC controller I few things came up. First was we bolted the heatsink to the chasis. As it turns out the heat sink is connected to the battery +ve. Big flashes when a ground lead touched the chasis. Problem solved by using insulating kits for the MOSFET that didnt have them fitted. It also turned out that the weapon channels can only switch upto 12V as there is a voltage clamp on it and I wanted to connected it to the 24V solinod directly as it could supply enough current. Actually I connected it anyway as the instructions didnt give a max voltage limit and the valve kept clicking every time the battery was connected and I thought the IBC was not working. It turned out be clamping it to 12V so I had 12V across the coil when off and 24V when on. This was easily fixed by altering the clamp to the battery voltage.

Back on subject. A range check with the BEC built into the IBC controller gave no noticeable reduction in range from using a 4.8V Rx battery. Although the IBC doesnt have opto-isolators on the Rx wires. Range was alot further than big nipper. That is without the Compressor running.
