RE: servo/boost tabs
As I stated elsewhere above, I have found that boost tabs can be very beneficial if properly installed. What I did not mention and should have is that static balance is also very helpful and more desire able when using boost tabs than otherwise due to the usually added weight aft of the aileron hinge line caused by the boost tabs. Static balance is especially important on the larger models as G forces on the less than perfect landings can seriously strain the aileron and elevator servos. You can get by perfectly safely with quite weak servos if both static balance and boost tabs are used.
