There are a number of suppliers that sell tiny prebuilt RC control modules relatively cheaply. Unfortunately these units run on 12v input power to drive their relays and while they will run on a 9v battery at a push, that still leaves me having to provide 2 supplies in most cases (one for the RC receiver and the other for the controlled device.)
Could the basic curcuit of the mintyboost be changed to provide a 9-12v output? By selecting different components could the same PCB be used?
Different output voltages?

I found a similar boost regulator, a MAX761, that will do the job I think, the Maxim reference design for both parts is very similar. You said in the Mintyboost design notes that you used a capacitor pair to smooth the output, what determines the size and type of these capacitors?
I'm going to order and build 2 Minty's first so that I can practice on a proven design, thanks for your help.
