so I needed to pull the canopy off my H-9 Mustang any way to mount some of the cockpit do dads and a pilot,so since I use a Voltwatch any way all the time, I ordered a couple off the "Bay"and started installing them,a little black Sharpie to make it blend a bit more, and I am pretty happy with the look of it.
its just one idea for mounting them instead of on the side of the plane,well worth the few $$ for the piece of mind of knowing your battery level before and after flight.
