Heaps of great info guys thanks. After checking through them all I believe I will be going with the 6060 at the root and 6061 at the tip. Finally Red do you use any wash out? or you find no real need for it so far? I've had a few people here tell me you NEED it but have never HAD to really use it before on kits or scratchies, however I have not built a machine based around speed before.

Tip stalls aren't usually an issue for me as I always do my best to test aircraft stall speeds at height on test flights so I get an idea of what kind of a suicide mission I'm flying before I go slow and low. Though there is always "that time" when you get caught with your pants down (caught by suprise) and you find out how well an aircraft cartwheels along the deck.
