I did that mod to my cub early on, right after I discovered the OEM gear bent so easily. You can see it here. I still have that gear on the SC and love it. supercubclub.proboards78.com/index.cgi?board=whls&action=display&thread=1011Make sure to read the whole thread because there is another mod that I talk about that will really make the gear solid. One thing though the J-3 gear is narrower and a little lower than OEM. |

Heh Heh Heh...
Put some of those J-3 landing gear on, man they are some kind of springy! Well they do seem to work better than the stock wire ones but now I have to rig up a new way of attaching them to the under carriage. Was out this morning, new landing strip (parking lot with curbs and trees in it) and ended up "tripping" on a curb as I was trying to land. Plane came floating in and sure enough WHAM! the landing gear struck the curb and ripped the front half of the battery box out. Had the LG screwed into the plastic lip of the battery box but as I re build it I'm using 3 screws 1/2 inch long to attach the LG to a segment of tongue depressor and Gorilla Glued the wood to the part of the fuse that angles up toward the cowl. This way I'm hoping that with only a little bit of each screw in the foam then in the event of a bad landing the wood and LG will break away rather than rip out the battery box, just hope it doesn't rip out too much foam. Any thoughts on mounting the LG on the upslope of the fuse? Of course it'll probably throw the COG way off so I'll measure and adjust for that later.

Oh, now that is looking nice! I've thought of using just the metal skirts over the stock wire, just like you have but thought it would just leave me in the same boat, bent wire landing gear. Now that I see you've done it I'm having some serious 2nd thoughts. Wondering about where you have the wire landing gear passing thru the J-3 LG: Does that transfer any shock from a bad landing back to the SC battery box? Heres a pic of the way I mounted things  Hopefully it'll break away in a bad crash (or hitting a curb) and not take the battery box with it. PS That black thing is a velcro strip from an old battery box, use it to keep the string I use for wing struts secured around the X port tube. And that thing that looks like a piece of paper shoved under the wood, that's exactly what it is! Just something to fill the space until I mix up some epoxy. |

I put the stock LG wire thru the axle hole on the J3 bracket. It took just a little tweaking to get it lined-up right and now the metal skirts take the brunt of a less than perfect landing! It still transfers to the battery box but I've slammed her down on asphalt, and it held up nicely! I'm strapping on a 5oz camera to her so believe me when I tell you that my landings can be less than ideal  |

This evening I was flying in some fun winds, not strong enough to take the fun out of flying but strong enough to make things interesting. A lot of wobbling coming in to land level, but that was part of the fun. Sure enough on the 5th battery I'm coming in just over a fence to land on the asphalt and "tink", tore off the whole landing gear assembly. Good news is that the LG stayed intact and the foam fuse had 3 neat little holes where the screws were sunken in, so overall it broke away just as hoped and left minimal damage. Everything after that was a HL and landing in some 5 inch grass.

With the stock wires, I was bending them back to shape after just about EVERY landing (yep- I was THAT bad). With this new set up, and the 3" tires, I haven't had to do an alignment on her yet! Those skirts have just enough flex.

Another case where I get modding and when I'm done think "Gee, I should have been taking pictures of this along the way." Got the J-3 LG situated where they work well (still on the upslope of the fuse) and don't stress the battery box but they were still way too springy (bottoming out on almost every landing and bouncing the plane back into the air a foot or two). I ran some thin wire between the bolts that held each wheel to the metal skirt and that worked well for 3 batteries, then the wire started showing some abuse and looking funky, so I took it off. Settled on using a 3/4 inch wood screw as the wheel axle, bring the wheel close to the outside of the skirt but still spinning freely and screw it into a 6 inch piece of fuel line running to the other skirt, repeat the attachment of the other wheel and it's like the Cub has a solid axle that prevents all springiness.

Man, gotta stay above the fence! Happened again, coming in for a landing, clipped the top of a fence and tore the LG off (belly landed smooth as can be, X port tube on asphalt) But again, neat holes in the fuse and LG intact (Gorilla Glue time) But I did have several good landings with the "plastic axle" and am happy with the set up (at least for now)

Got 'em glued back on and went out for some more flights in some pretty windy weather (something I would not have even dared to do 10 months ago). All went well but that wind just took most of the fun away. Did some pretty interesting manuvers (actually the wind shook the plane like a rag doll) but came in for some feather lite landings. Packed it up and called it a day while I still had a plane to leave with.

Been over a month and this LG is holding up A-OK. Did have to cut a 1/4" aluminum cylinder to fit in between the skirts, and use slightly larger screws as the axles (would barely fit in the cylinder and Gorilla Glued them in) Of course being smaller LG and mounted forward of the battery box there is an issue with prop clearance and being nose heavy. Am happy that the whole LG assembly will break away before being damaged, thing is it takes away a little more foam each time (eventually I'll be flying a chunk of Gorilla Glue)

I bought a similer after market lg from the lhs. Had to do a lot of work with the battery door, added weight and finally it worked less well than the stock lg with 2 1/2 tires. I took it off.
I recently added some copper tubing to increase axle diameter. Next I'll try some of the re-enforcement mods on this site.
Most recent advice from an expert: rog and land from pavement.
With careful landing techniques, I've had some nice touch-downs. Rog's almost never. It would be nice.
