I saw this airframe concept a few times over the years and it always looked cool. I’ve been told it’s an Ace Combat plane but I can’t confirm that. The concept plane had rocket engines. That’s where I came up with the idea to have top and bottom intakes. This air frame is extremely small and compact for being a twin 50. The greatest strength of this airplane is how easy it is to hand launch. Especially if you go with a 3S power system with 5 fans. I have flown both versions. One with 3S counter rotating fans and two. A 4S power system with similar rotation. Both are easy to hand launch. The air frame flies very nicely, tracks straight and has lots of power. I have provided two rear fuselage versions. One that standard, no thrust factoring, and two that offers the ability to use thrust vector veins in the exhaust. You choose which one you wanna build.
Length 31”
Width 24.5”
All up flying weight with vectoring and 4s 2200 958G
3s non vector will be 100g lighter

Parts Needed
Any twin 50mm edfs. 3s or 4s your choice
Any 40amp ESC’s 2x
Y adaptor for dual ESC’s
3.5mm extension wires for the fans
Non vector version needs 2X 4.3g servos
Vector version needs 2x 4.3g servos and 2x 9g servos for the vector vanes.
Servo extension wires 4X
1.2mm pushrods for elevons
Hot glue for the fans, servos,and vector vanes.
Flying the vectra is straight forward. Elevon control for the non vector version. Turn the roll rate down to 75% with 25% expo, use full servo travel on pitch. You need all the elevator you can get for landing. She likes to drop the nose a little on landing.
