Concept Bush Plane Configuration!

I’ve had the idea of building a twin engine STOL plane like this for a long time now; ever since I built my Scout Eagle!
The advantage of this twin-engine, twin-tail configuration is that the prop wash from the propellers generates lift on the wings and the twin tails increases low speed stability. The twin engine configuration also makes this aircraft extremely powerful, and it can carry a very heavy load. It has a maximum climb rate of nearly 4000 ft/min when unloaded, which is significantly higher than any other plane in it’s class.
These performance figures seem pretty outrageous, but the engines on this aircraft are literally copied over from the Kitfox I made last year, which has very realistic performance. The two Rotax 915 engines with MT props generate about 600lbs of thrust each, giving this plane 1200 lbs of thrust in total. As a reference, a stock Cessna 180 generates about 750lbs of thrust from it’s single engine. And it’s less efficient than this plane.
Relocating the engines to the wings doesn’t just improve performance, but it allowed more freedom to be made with designing the fuselage. It allows the entire nose section to be a window, which is excellent for visibility, especially during slow flight. Relocating the engines to the wings also means the landing gear can have a heap more travel than on normal configuration planes, since there isn’t any prop that can hit the ground when you bottom out anymore.

It seriously baffles me that a plane similar to this hasn’t been designed yet. It just makes so much like this!

Performance
Stall speed at idle: 28mph
Stall speed power on: 19mph
Max speed: 170mph
Cruise speed: (60% HP) 140 mph @5000 ft
Cruise fuel consumption: 7 gallons/hr @60% HP
Roll (from -45° to 45°): Approx 1.8 seconds @ 140mph
Takeoff distance: 80 feet
Landing distance: 25 feet

Controls:
Standard controls
VTOL down: Flaps
Act 1: Start engine 1
Act 2: Start engine 2
Act 3: Open doors
Act 4: landing light
Act 7: parking brake
Act 8: Master and stuff

STOL Takeoff:
Set flaps half down and trim full down
Hold the brakes and set full throttle.
Wait until the tail comes up and release the brakes. Control the tail height by using elevator
Once you reach 20mph, set your flaps all the way down and pull all the way up
STOL landing:
Set up for a low, relatively long approach
Set flaps and trim all the way down. Pull up to get behind the power curve. Power curve is about 35mph
Set your throttle to around 35-40 percent and control your airspeed with your pitch. Aim for about 25 mph. Adjust your approach angle with throttle
Keep flying low until you get to the threshold where you want to land. Cut power and plant yourself on the ground. Apply full brakes.
Screenshots: none :(

Enjoy!
