I have some photos of pattern planes taken at a couple of contests in Lancaster CA and Santa Maria CA in 1986 that I would like to send to CAsniffer but I need some help identifying a couple of the planes. I have attached the photos I need help on.

First photo has 4 planes in it and was taken at the Lancaster CA contest in 1986. From front to rear they are: Dash 5, Phoenix 8, unknown (lavender or purple and white plane) and a Tipo. Can anyone identify the lavender/purple and white plane?
Second photo taken in Lancaster CA in 1986
Third photo was taken at the same contest
Fourth photo. What is the plane in the foreground? Taken at Santa Maria CA contest in 1986

Thanks for your help,
Ed
