SAAB J21.
The unorthodox SAAB J21 fighter was a domestic attempt to provide the Swedish Air Force with a true high performance fighter. It's design was conducted during war years, when there was no practical possibility for Sweden to acquire modern aircraft from abroad. The J21 emerged as a very advanced airframe with streamlined shape, twin tail booms, laminar wing profile and ejection seat for the pilot (which actually worked well in service, unlike some of the early ejection seat designs of German Luftwaffe). A total of 298 SAAB J21s were produced in five production batches. They served from 1946 to 1954.
Series aircraft were not without problems. Because of the propeller's placement, engine cooling proved to be inadequate, especially on the ground - a serious problem that was never really worked out. The aircraft also lacked the agility necessary for a dogfighter. On a positive side, it proved to be a good gun platform and was easy to start and land. These properties lead to the decision to adapt the J21 to ground attack role.

Model and color scheme by Willsonman.
Various modifications for RF 7.5. Standard flight controls plus retractable landing gear, landing flaps, and brakes.
Fly with the channel 5 rate switch in the “High” position.
Fly with the Interlink controller channel 8 switch closest to you. Clicking one position away from you activates the brakes.
Lands well with or without flaps. This aircraft is not a particularly good glider.
This aircraft design has a peculiarity with its take off. If taking off with no flaps, the aircraft will literally leap into the air after gaining airspeed. For a gentler more manageable takeoff engage full flaps first, then apply mild up elevator as airspeed is gained. After liftoff disengage the flaps and retract the landing gear.
This aircraft is a fairly decent flier. Give it a try and see what you think.
