The 3/16" wire struts are rated up to 12lbs.

From the three you've looked at I would choose the FIRST because those wire struts have the in-line "sping" bent into the wire.

That sping will help to absorb the shock of landings and purposely deform temporarily.

I would go with that.

You'll also want to beef up the mounting area as much as possible.

Some people merely slop on a lot of epoxy and/or TRI stock hardwood on the existing blocks.

Unfortunately that does NOT spread the load out.

What you want to do is to increase the area where the torsional forces are applied.

Remember that the long gear strut acts as a "lever" against the wooden support block.

What you want to do is to prevent that support block from tearing out.

The best way to do so is to increase the size of the surrounding wood supports onto the wing.

I typically install hardwood strips to lengthen the supporting area, thereby spreading out the load over a larger area. Two or four strips and a few tri stock angle pieces go a long way in beefing things up, and add little weight.


The last option you gave seem to be servo actuated gear. This will be more complicated than using pneumatic landing gear.

With Pneumatic gear the only extra thing you'll want to get ( other than what is in the kit and the actuation servo which can even be a mini or micro servo ) is a set of pneumatic "quick release" connectors.

That will permit you to quickly disconnect the wings from the pneumatic lines.
