Crist,
First off, it was a pleasure getting to meet you and hang out some with you at the Nats. My SV22 is using an FM-9 VR with remote start button. This one gives me a + or - 200 variable rpm adjustment at 9500 rpm just by turning the variable resistor on the side of my plane. I only have to go to the prog box if I need to go further than that. It makes for easy on the spot adjustments. You can also get them with just the remote start or with a different + or - number. Just tell Will what you want. He gives us lots of choices. If you want a picture of my spare let me know and I'll get one up tomorrow after work.
William
