Thank you all for your replies
claycomm: Thanks for that, I'll keep that in mind for the next time, and see how it works out.
BlueRobin: No, they are counter rotating.
Jannik23: Good point, thats what I normally do on the singles, I'll try flapless next time.
speedrestriction: Thats an interesting point. The rudder will be more effective though with a forward C of G due to rudder having a larger moment arm, so this would work in my favour.
