Building and flying Dyn'Aero's MCR 4S kitplane

Aircraft homebuilding

IF+GTH
Photo NM

From 2001 through 2004 I've been involved with Igor Fedoriw in the building of a Dyn'Aero MCR 4S four seater kitplane. It is a two man project.
Among other tasks I've been in charge of the electrical circuit and radiator duct optimization.

The MCR 4S project first flew in November, 2004. It has been tested up to FL 145 at temperatures ranging from -14°C to + 37°C with very good results.

The MCR 4S was ferried to it's homebase in March, 2005

The aircraft performance is outstanding.

 

 

November 24th 2004

First flight at Dijon-Darois

July 2005

The flight tests have been successfully completed.
The paperwork is done and we are waiting for the Civil Aviation certificate of registration.

September 24th 2005

The certificate of airworthiness has just arrived. Our MCR 4S project is now fully registered.

 

 

What's to be seen on Contrails !

Technical articles

Contrails ! covers numerous aspects of homebuilding, which might interest many hombuilders, whatever their project.

A few examples :

MCR engine

  MCR electrical circuit
Designing one's electrical architecture, choosing wires, protecting circuits, practical wiring.

  MCR 4S instruments
Installing fuel-flow, radio and GPS, antennas, coaxial.
See Manuel Bonniot's article on the Dynon EFIS.

  MCR engine cooling
Aerodynamics of the radiator, cooling drag, wind-tunnel optimization of an MCR 4S air inlet diffuser, etc.

Your feed-back is most welcome !
