I am NO expert in retracts since most all my Planes are either sport or non-millitary scale, but I have noticed that sometime problems can occur when using "cheap" retracts. In my own observations I have concluded that this is one item that a person would do well to spend a little money on unless a person is proficient at one wheel landings, or belly landing. I am sure someone with more experience in regards to retracts can point you in a direction that will be to your benefit.
