Here's where I am so far on the H I started before the holidays. Ended up trimming the arms and drilling out some of the plates to lessen the weight. Will likely add some CF rods as prop protection during the tuning process.
Using 10x4.7 props for now, though the motors could handle larger. Testing has it hover at just under 50% throttle, so I think I am in a good place. Not tuned yet - that's next when the rain lets up.
The APM is enclosed in a very stylish $0.99 plastic box from Office Depot. The stack sits on a fiberglass plate attached to the body plate with 3M double sided foam squares. The lid of the box is velcroed to the FG plate and the APM is velcroed to the lid. The bottom of the box forms the cover for the stack and clips on.
Still need to rig up battery straps, the external LEDs for GPS and arming indicators, some running lights, a GPS enclosure, and general cleanup.
