As discussed earlier, I rebuilt my quadcopter frame. The original design worked fine, but I had a few new design goals with this frame;
- Integrated motor mounts with the arms for simplicity
- Separate arm holding plates and electronics module for the ESCs
- Bigger central FCU container (for an AQ 2.0.7 shield)
- FCU board mounting direct to a levelled metal plate
- Vibration decoupling between the arms and the electronics module
Anyway, here’s the finished result;

The finished frame appears above. Design is very similar to the old design, except now there’s four plates. Plates 1 & 2 bolt together to hold the arms in place. Plates 3 and 4 bolt together with spacers to provide an enclosure for the ESCs and other electronics. The ATmega attaches to the top of plate 4 with nylon standoffs, and the FCU container bolts onto Plate 4.

The landing gear is a set of TRex 450 (I think) landing gear that I got from HK for like $3. The battery straps on with velcro under the landing gear. The end result is quite a lot taller than the original design, but it has a lot more space inside and can be disassembled in a much more straightforward manner.
