The KBDD MCPX skids really improve the durability and visibility of the Nano, but they require a bit of modification to fit the frame and accommodate the Nano's lipos:
Cut the top of the battery mount away with a small pair of side-cutters to allow it to clear the bottom of the 3-in-1 board.
CA a ~1/2" long piece of 3/8" heatshrink tubing in the center of the battery mount (I learned this trick from a YouTube video). If you're very careful with the glue, you can install a lipo in the tube while gluing it in place to help you handle and precisely center the tube. Apply a small drop of CA to the top and bottom mating surfaces.
It helps to roughen the outer surface of the tubing and the mating surface of the skid with some sandpaper before gluing. I pre-stretch the width of the tubing for a slightly looser battery fit by inserting a pair of needle-nose pliers in the tube and spreading the jaws apart until the lipo will slide in without much resistance but remain fully seated in a crash.
Carefully and gradually file down the width and thickness of the two frame mounting posts until they fit the Nano frame bosses. I make them a tiny bit loose so the skid can pop off in a hard crash, rather than incurring damage to the frame or 3-in-1.
Optionally, snip off the center 'H' brace to allow the frame posts to move a bit closer together. IMO, the skid is strong and rigid enough for the little Nano without them, and you have better access to the main gear when you need to fully re-seat it on the shaft after a crash. If the brace is left in place, the skid tends to bow a little and the fit isn't as secure.
These tiny tough-as-nails canopies are made from the small half of a common plastic Easter candy egg, which has a 1.68" outside diameter at the widest point. They're juuuust big enough to accommodate micro-quad frames like the V202, H36, and of course, the mighty Frankenquad V2, so they have very little "parachute" effect, and they're very quiet in flight. The V202 beetle canopy weighs 1.5 grams, while the little egg punishes the scales at 1.85 grams. I can live with the extra 0.35 gram. Maybe you can, too!
The plastic is so tough that it's difficult to get a drill bit to bite (a hole punch barely scratches it, even with hands o' steel) so set the egg over the frame legs, mark the hole positions with a strong, sharply-pointed spike/scribe/pin, and carefully work the point all the way through the plastic. That'll provide pilot holes to keep the 5/32" drill bit from sliding all over the place. A little extra time spent checking that your pinholes are uniformly spaced from the edge and one another before drilling will assure that your canopy sits level and tight on the frame.
The eggs snap together with a lip on the small half, so use a sharp scissors to trim that away and sand the edge smooth. Keep the mounting holes close to the rim, otherwise the canopy will sit too low and hit the FCB connectors or impede the lipo tray. I located the center of mine at 0.10" from the edge (the holes shown on the yellow egg below are a little too far from the edge,...Continue Reading
I've wanted to pursue the heli hobby for decades--even built a GMP Cricket heli back in the '80s--but I've been waiting for affordable technology to ease the ache of the learning curve. The micro explosion appears to be the ticket!
