Which model of Angel? As already said above the voltages are different to work properly the Angel that has an A4 boards put in it needs an Speed/A4 battery and the A4 or Speed charger unit...the solenoid may need to be replaced or have a capacitor soldered on as the voltage output from the A4 board will not be enough to trip it sucessfully everytime without the dreaded FSDO. If the Angel you are getting is a Speed then an A4 board will drop straight in and no further fiddling is needed.Originally posted by craigpil
can definately be done cos the angel i am getting very soon has an A4 board in it, not too sure about wether the rest of the internals - i.e. the solenoid have to be upgraded aswel
been told that it absolutly rips though
