eVektor EV-55M Outback – Introduction

This is the toughest most shark-like aircraft since the Fieseler Fi-167 – and it’s a twin engine. My favourite type of aircraft. the EV-55MV is built by the Czech aircraft manufacturer eVector Aerotechnik. So far one prototype has been made.

The aircraft is designed using the latest CAD tools, and I have received a set of drawings in full scale showing the general layout, all major fuselage formers, and wing profiles. Making a model of this aircraft will be so much fun.

General characteristics

  • Crew: 2
  • Capacity: 9 passengers (normal class by airworthiness standards) or alternatively 14 passengers
  • Length: 14.35 m (47 ft 1 in)
  • Wingspan: 16.10 m (52 ft 10 in)
  • Height: 4.66 m (15 ft 3 in)
  • Empty weight: 2,626 kg (5,789 lb)
  • Gross weight: 4,600 kg (10,141 lb)
  • Powerplant: 2 × Pratt & Whitney PT-6A-21 turboprop

Performance

  • Maximum speed: 408 km/h (254 mph; 220 kn) at 10,000 ft (3,050 m)
  • Range: 2,258 km (1,403 mi; 1,219 nmi)
  • Service ceiling: 8,839 m (29,000 ft)

eVektor EV-55M Outback – 3-Views

As I said in the above post, I received a set of drawings in full scale showing the general layout, all major fuselage formers, and wing profiles.

 

eVektor EV-55M Outback – Scale

My model will be to scale 1:5, resulting in a model size of:

 

Wingspan: 3.22 m

Length: 2.87 m

Height: 0.932 m

 

A decently sized model.

 

eVektor EV-55M Outback – Status

After 2 evenings of work, here is what I have. The documentation from eVector is really awesome. There has been absolutely no cleaning up of the 3-views. Everything just fits together perfectly.

 

eVektor EV-55M Outback – Landing gear pods

Here is the key to the design of the pod covering the rear landing gears – it is airfoil shaped. This is not immediately obvious when looking at the formers, but they (almost obviously) are airfoil shaped.

It can be seen on the pictures of the actual aircraft.

I will implement these pods as two fibre-glass shells and a simple plywood skeleton. This is a strong and light building-method with room inside for the landing gears.

 

eVektor EV-55M Outback – To do list

I now need to do the following:

  1. Complete the engine pods. The rear bit is missing.
  2. Cut out the wing from the engine pod.
  3. Clean up the fuselage under the wing attachments.
  4. Fix the pods with the landing gear. I still have not got the shape quite right.
  5. Cut out windows.
  6. Cut out the fuselage formers and reduce the outside by 3 mm to make room for the skin.
  7. Cut wing into main wing and ailerons.
  8. Cut elevator into a fixed and a moving part.
  9. Cut tail into a fixed and a moving part.
  10. Draw the wing formers, spars, engine attachment and hinge points.
  11. Draw the elevator formers, its spars and hinge points.
  12. Draw the tail formers, its spars and hinge points.
  13. Draw the formers for the engine spars.
  14. Draw the landing gear.
  15. Draw various cutouts.
  16. Draw various hatches.
  17. Draw R/C installation.
