The tail spring is a used unit I got from 3 Tracks. My plane was built for a 1-1/2 wide spring, so I had to do a little machining on the bracket to make it fit. I ran it a couple hours before putting on the tires. It is stiffer than my old steel spring, but it won't sag. Also, you have to look close, but I updated the tail tire. I used a 6-ply Aero Classic tire instead of the really crappy 4-ply that came with the Matco assembly. The 6- ply is $40 and the 4 is $38. Easy choice.
The 26" Airstreaks are also used, procured on the trip. I put 1/2 a gallon of Herculiner on them to "retread" and they should be good to go for a while.
Flight testing will commence in a couple hours. Have to mow the lawn, first...
