I have SafeAir 1's static port kit but I've read some things about them not being very accurate due to difference in their protrusion from the side of the fuselage vs. the cheap ole pop rivet that Van's uses. I ordered a static kit from Van's and recieved it so I could see the actual pop rivet they use. I think I'll make some ports similar to SafeAir1's and make the protrusion the same as Van's pop rivet.
