This is one of my old modified L-39s. I lost some of the newer ones but this is still fun.

Modified L-39 features an STOL (short takeoff and landing) flight mode with thrust-vectored down and gyro-stabilized spoileron roll control for stable slow flight. Also has air brakes and smoke. By Jesse

3-position switch selects flight mode:
up- normal flight
middle- standard flaps
down- STOL
note: also controls dual rates and retracts

left switch:
up - brakes off
down- wheel brakes on and cuts throttle
down AND in STOL mode- adds air brakes

right switch:
up - smoke on
