Ben....Dick.....Bank-to-Turn....Are you gentlemen familiar with Hobby-Lobby hinges?.....They make great flap mounting hinges....I use them on all my "Big" warbirds....they make the flaps operate more closely to "Fowler" type of flap which during flap extension go "BacK" as well as down... this gives the wing a slightly larger surface area for lift as well as some drag @ lower flap settings.......There is a definite difference on T/O for example with flaps up and say flaps 15* ....T/O roll is shorter with ability for a higher rate of climb....not to mention nice stable approaches and landings.....Bill......
