FFF
Heavy control forces on an Aztec on T/O means your trim was not in the best position prior to your take off roll. Use of the electric trim makes getting back into correct trim painless during climbout.
The disturbing changes are during gear and flaps down, but I believe the E and F models had sorted this agrivation.
The easy control of an Islander is I believe due to the much lower airspeeds of the Islander.
