I also second the dual servos in the center using the current servo cut out. Its an easy mod and you can also allow your Tiger II to have Flaperons for a slow crawl landing speed. Right now I am using the single servo set up and its working just fine, but I have also had the ARF with the dual servos mounted outboard in the wing panels, and that was nice too. If you have a mixing radio, the flaperon feature is nice. I am curious about the Tip stall tendency that the flaperon might create though.
