Landing gear for rc planes

I've got a few sets of landing gear for rc planes. The 1s iam selling in this post is the 2 wheel front landing gear and the 2 backs. They are spring loaded. They are around 4 and a half inches long and foam tires. They come with 3 metal brackets. Iam not sure what they will work for I got a few sets different and I thought about making them work on my yak-130 and a few other jets. And planes I could get them to work on. But I don't have alot of time left it's looking like. So iam just not going to do anything with them. Some of the jets and planes I have but iam not going to use them now. The first few pictures are the 1s for this post. Others will be posted soon. For closer look at them if u don't like the 2 wheel front. Or rod size is to small. Thanks for looking.
