RE: DA50 Choke connection to servo
If you are getting a DA 50 order it with the 3" stand offs. If you can't get one with the 3" I believe you can swap them direct from DA. The total length required for the stand off is 3 1/4" typically. I say typically because of the 4 planes I have built 1 needed a 3 3/8" to get the length needed to clear the cowl. If you have the spare $$$ you can have a custom set of stand offs made for $40.00ish from what I have seen.
