No POH to hand either so I cannot confirm or deny, but having to use the main tank for take-off and landing is something I have not heard before. It's also not in the club checklist. And I can confirm that the aircraft takes off and lands perfectly fine on the saddle tanks - but I have to admit I have never come close to running one of the tanks dry and I would not want to land or take-off with an almost-dry tank selected in the first place.
What I have done, and which may serve as a warning to others, is select the fuel selector "off" while I intended to select the main tank. We were at 1000' when it happened, and fortunately my pilot passenger caught my mistake immediately. Otherwise we might not have recovered in time. Reason is the on-ergonomic design of the fuel selector, where backwards is the main tank, and forward is shut-off.
