Hey guys
Well I love the cub, and my fatgher even is getting the hang of flying it as long as there is no wind, (or he has a hard time).
I actually have another cub on the way which need minor repairs, and picked it up for 80.00 shipped, for him. Well I am doing very well but one needs a perfect landing inorder not to "rim rack" the landing gear. I do have 2.5 inch wheels on the front, and a 1" on the tail.
My white skirts broke up so they not on the plane.
Imade little "saddles to help with holding the lading gear down on the plane, it works well. Also put a piece of wire between the lading gear to stop the lading gear from spreading on ladings, worked but lading gear is still tweaked a good amount. SO I am always rebending, tweaking the landing gear.
I need anti flex idea's or another type of landing gear to go with that will not be to heavy.
Thanks everyone!
George

I found that c/g on my S/C was too far ahead, and getting nice, slow landings was difficult. I taped a small weight to the tail, and landings became a breeze. With the c/g in the right place (not too far back!), one should be able to land on trims alone.
My buddy changed the gear on his Beaver to the full, shock-absorbing configuration using rubber bands, and it worked well enough to allow grass stains on the belly without bending the gear...

Flex is good. That's what keeps your plane from getting ripped up on rough landings. The more rigid the LG, the more stress on the battery box. Reinforce that and the force goes somewhere else - ultimately the foam pays the price. My advice is get better at landings and get an extra set of LG.

My buddy put a rigid set of LG on his Magpie since there seemed to be issues for new fliers with bending wire type. He totally ripped it out so many times I lost count. Every time it got more glue and ply-and it got heavier > so it landed heavier. Vicious cycle.
Yes, some LG is so pathetic it needs reinforcement. Often this is one of the most skimped on things on some planes. But for the SC listen to Ellis. Ultimately, you have to learn to land better. If you don't it'll haunt you on future planes that are not so robust.

How about a springloaded landinggear integrated into a new battery box? That was my solution to first bending back wires a lot, then reinforcing the gear with the result of the battery box and foam getting damaged. It seems the forces (dampened) are being spread out to a much larger area, therefore no more damage. I also put bigger wheels on (2 1/2"), landing on not so smooth grass is a lot better now.  |

How does the spring part of it worrk? Do you have better pics of the spring setup?
I would like to leave the sotck batt box, I have reinforced that and is holding up well.

What did you use for a battery box?

It seems to be similar to Delrin, just some stuff we had around in the shop. It probably doesn't matter what, just get the forces spread out over a larger area. I can imagine making something similar without having to design and machine a part, even with plywood.
It's too bad we have so bad weather here, would love to be flying.

Man, that sure seems like a lot of ironmongery to be towing around! IMHO, this is the start of the merry-go-round of add strength, add weight, add power, add strength, add weight...
I'll see if I can get pics of my buddy's gear; I don't think it added more than a couple of ounces to the weight of the model, yet is fully flexible without bending.

Ok, all is true, the unit weighs about 100gr. But: after changing to brushless and Lipo I needed to add weight forward anyways, more fun to make a nice piece than taping on lead to get the CG right. I have the Lipo vertical against the firewall, that helped.
I can still take off, using the hood of my car as a landing (starting) strip, crossways, and it's not a Hummer. It's like taking off an aircraftcarrier without a catapult.
I guess I just like to try stuff out.
That's what's great about this SC. You can do it and it will still fly.
I'm sure I'm not done with my modifications. I still only have a take-off-weight of 750gr. With ailerons, with 2 1/2"wheels, with ventilated landingflaps, with a lot of epoxy, toothpicks and tape.
Hope you're having as much fun as I am.
