Inquiring minds want to know just what the deck angle might be on climbout, to see (geometrically, anyway) what the reduction in head pressure might be under that condition vs. straight and level. Has anyone put a smart level on the longeron to see what it reads in climb, say like at Vx? And Mark is absolutely right about trying to fly strictly off a header tank. Paul Martin's straight KR2 had a very large header tank, no wing tanks, and he ended up reducing the volume of it because it could really do some wierd things to the CG flying from full fuel to 30 min. reserve. You could take off on a x-c with everything looking great, only to find yourself in trouble when setting up to land at your first stop.
