Cheers Andy. Yes still using the drill batteries for now and looking at a 12v Linac so 3S would work for everything when I get round to upgrading to Lipos. Any ideas on battery capacity required to run everything?

Currently the wiring coming from the fuse spilts to go off to the Escs and light at the same point (with linac wire to be added in) is there an easy way of soldering all these together? Currently this point is held together with electrical tape
