I've been slowing inching into the multi-rotor hobby. Started out with a Blade mQX RTF kit, and once I was able to fly that reasonably well, I upgrade my transmitter to a 9X (running er9x, and some minor mods) with the OrangeRX DSM2 module. Next step is building my own H-quad.
In looking at the design, I've had two brilliant ideas so far. However, my experience in other fields has taught me that a newbie's brilliant idea often overlook some obvious issues, so I figured I'd share them here.
Power distribution
I like the power distribution system Josh describes, but it seems like it would be a pain to swap an ESC (in the event of failure or upgrading). I'm considering mounting two terminal buses inside the 'box,' running lengthwise, on opposite sides of the frame (near the middle). I'd use something like this. The major issue I see with this is the need to insulate the outside the bolts holding the bus bar to the light ply (or use some non-conductive fastener). Would suck to set it down in damp grass and short the battery...
Move spacer to the top and use foam
The original design has a removable bottom. All else being equal, I think this is the better of the two panels to remove (since there's less attached to it). However, I wonder if there isn't opportunity to reduce vibration a bit more by moving the balsa spacer to the top, and replacing it with foam. You'd still likely want to make it removable (to have access to the wire 'notches'), so there would be screws, which would conduct some vibration, but I suspect having the top plate 'float' on a foam spacer would be a win in terms of vibration dampening.
So, what am I overlooking?
