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 tried earplugs and stick-on cabinet bumpers as motor/wire/frame protection tweaks, and while they work fine, I wanted something less compliant (and more horizontally level) than the former, a bit more protective than the latter, as well as something that provides a wider stance than a heli skid. I had some spare landing feet from an RC Logger Eye One (thanks again, Stonecutter), so I adapted them for the X4 and I'm pleased with the results. I think it looks pretty cool, too; gives the little guy a purposeful silhouette, and as far as I can tell, it flies as well as the stock version.
The individual Eye One feet weigh 0.5 gram each, so the total weight of four feet and four small zip ties tips the scale at just under 2.5 grams. The feet have a little shock absorbing 'give' to 'em on hard landings, but they're rigid enough to keep the little bug level on the ground.
Just snip away one section of web in the back of each Eye One foot with a small wire cutter so the top can expand, slip it on the X4 motor pod*, and thread a small zip tie through the slots in the front of the foot and the nicely-matching slots in the front of the X4 pod (bending an outward curve in the end of the zip tie helps to guide it through all the grooves). Wrap it around the foot and secure it tightly under the leg.
*When using these feet on the X4, they're rotated 90 degrees from their orientation on the Eye One.
Here's an RC Eye One foot with the section of web snipped away:
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 cost of the learning curve. The micro-quad explosion appears to be the ticket!
