first time for me too, for me, it seemed like "small" changes are a must vs my normal ' instead of moving one hole I'm going two holes' approach to setup changes. tried out the 9650 servo, seemed to be ok, need to check spring tension on a kimbough vs stock shouie saver. although being so under weight i may decide to go with a heavier servo. i also just figured out that a narrow rear arm is the same size a stock front arm, so that will play into my setup decisions.
