Fred,

you sure make an argument, and a pretty darn good one! I did not consider pneumatic retracts (because of the cost) but you are right, it is probably the best way to go... let me sleep on it for a little while. As an engineer, I rahter go the "difficult way" first... hahahahaha

As I read, you do not recommend cutting the ailerons to install flaps on the Tiger.. ok.. About the gear doors: thanks for the warning as I WAS CONSIDERING THEM!

Take care
Carlos
