I like that design, Ian. I have been putting some thought into totally redesigning the landing gear myself, but am probably going to go the heli skid route instead of 4 individual legs.
I made 1 minor change to my 3DR frame that has made a major difference for me. Very simply I took 8 extra plastic center shaft adapters that come with the props (the ones with the small holes) and ran the motor bolts through them on the outside of the frame - this has reduced the noise and vibration dramatically. I am also planning to test mounting the motors on top of them as well (between the frame and the motors) - I am thinking that this will further reduce dampen the sound from it. I would recommend that anyone that has a 3DR frame swap out the metal washer that is supplied for the motor mount for one of the plastic "washers" that is supplied with your props.
I have also upgraded to 12" props and it is flying like a dream. I am sure the experts could find faults with it, but with the standard PID settings it is flying nearly tuned and responds extremely well. Once I have the landing gear and GoPro mount worked out I will be set.
for the motor mounts i will be trying out 4mm nylon 42 sheet to make my mounts. my arms are carbonfiber tubes and the nylon can be heat formed with wooden molds and a heat gun to make 'U' clamps to attach the mounts to the tube. the flexible but strong nature of the nylon should do good to absorbe some of the vibration. my landing gear will be made out of the same nylon doubled up and held on by phenolic blocks with a thin rubber pad inbetween them to prevent movement. the gear will be attached with nylon bolts as well. i dont have the motor mounts designed yet but will once i get my motors in.
I have come up with a plausible idea for the landing gear. I have decided to mount 1 off-road shock absorber to each landing gear by connecting it to the gear on one end to the frame at the other. Basically the connection from the frame to the landing gear becomes a pivot point. This enables the frame to not to have to take as much force on hard landing. I am still in the process of working all of the mounting out.
