I used the Klett main gear and tailwheel called out in the manual. It all fit perfectly and took me about 2.5 hrs. to complete the job. I am especially happy with the Klett main gear. I appears to be a composite of some sort and is light. It is springy so that if you come in for a hard landing it will give and bounce back to its original shape rather than the aluminum wich will bend and then good luck getting it aligned again. The Klett tailwheel setup is of very high quality too.
