Dear Dene I have come thinking of the retract gear already for time and I liked a lot what put Lancer in the first Lancair. It is simple, easy and I believe that sure. I have some picture of a RG that was made in US there are about ten to twelve years, very similar to that of the Lancair. If you need it, I look for them and I send it to you This uses as shock absorber some cylindrical sections of polyurethane. Eduardo
