I request help in determining the value for this stuff. Here is the breakdown with pictures to follow.

8 total planes - 6 large and 2 small. The large ones have a 42 1/2 in wingspan and the small ones ore 36 in.
2 large planes have Mejzlik Modellbau, Czech Republic printed on them.
3 large planes have GRS Models Metairie LA printed on them
1 large plane is unknown make
1 of the 1/2a planes has a tag from GRS Models on it
1 of the 1/2 a planes is of unknown make

5 engines are included and installed - 4 large size (.19?) and 1 small 1/2a (Norvel?),
1 large engine has MMB PROFI printed on one side and K03EN on the other
1 large engine has CYCLON printed on it
2 large engines have MAT printed on one side
1 1/2 a engine appears to have AMA printed on the side except the second A looks more like a triangle.

As stated in my previous post, I intend to list these on RCU but I need help determining a fair price to ask. What do you guys think?
Here are some Pics!
