Arun Queen update.

I treated myself to a proper battery for the Arun Queen and also added a voltage regulator so the receiver can run from it too , there was no BEC when this receiver was made  in 1972! I bought a 7.2 volt battery but really should have got a 9 volt as I didn't account for the voltage drop through the speed regulator 6 volts still gives a nice slow cruising speed and I wired a (very) crude bypass switch in so I get a boost for top speed.
