I am expecting my Flash to arrive today!, What are you guys using for reciever batteries and switches? Is anyone using a power panel or electronic switch set up such as the Duralite powerbox electronic switch. I plan on using 2 -Li-Ion batteries (2800 Mh) in parallel for the reciever with a Emcotec Mini power panel, Is this enough ? I will be using 4 JR-8611's for the wing, and 2 -8411's for elevators. Also how is the included Brake / retract valve that comes with the Behotec gear. Should I upgrade the brake valve to a Jetronic unit? Thanks for any suggestions , Jack.
