RE: Flat turn at rotation
This airplane was balanced quiet nose heavy. The airplane has also tracked very straight on the ground for the last hundred or so flights. Just after rotation it has attempted a 30-degree or so flat turn but only occasionally. Initially I thought it had an affinity for the big shade tree. Recovery from the turn simply required ruder and climbing out closer to the tree than preferred.
The balance has been changed and tomorrow another test flight will be made.
