Welcome back. Just a few odds and ends that currently are important. First of all the present radio equipment is light years ahead of the past. Without even going into detail about the 2.4 units, just any computer radio is practically mandatory. Electrics are the wave of the future they provide all that glow power does without the mess and cost of fuel (which is very high now). If you're not keen on building the ARF's are available in every concievable type. This and other forums can give you loads of info so use them.
