I have the 1.2 and these, I rough up the metal a bit and then use heat shrink to save on weight. I haven't had any wheels come off yet, a small drop of CA to reinforce, if necessary. Added a pic in the 'files' tab for you.
I have used these: www.link 36mm wheels for a plane of similar weight to yours. Works well. You also need to get stop collars such as these www.link to hold the wheels on the struts.
The hardest thing with these struts is fixing them to the plane such that they will take a bit of force on landing. If you use a single screw it will rotate around. I made a little housing
You can glue to a piece of wood, and all this to the fuselage... like a "cuaderna". It is the easier way... It is good for the structural of the plane and only you put up a little of the final weight...
you can glue 1 piece of balsa with a channel like the top part of the Landing strut ( a carved out 'U' ) between another 2 pieces of balsa, then use a screw to mount the landing ( put the landing wire in the channel the screw it near the inside of the 'U' ).
You will need 2 piece balsa wood and epoxy.
Just fret a way for the strut on the wood with a scalpel. After take on the other balsa wood and glue it with epoxy. Like this: HK-204
So take the neck of the strut between two balsa wood and glue it with epoxy.
After you have cut place for the balsa wood in the EPP foam with knife or scalpel and glue in with odorless foam safe glue.
