Larry,
I own an AA1 and it most definately does have baffles. The slosh factor is
still so important that the airplane is labeled " no spins" more than three
rotations and the fuel is forced through the baffles to the wing tips. This
starves the engine while increasing the spin rate. Pilot funeral happens soon
after.
Bill Clapp uses foam baffles in his KR with success. ( I think, please check
with him.) I will build the tube tanks because it solves moving CG problems
with fuel consumption. I will use the foam baffles.
