Building and flying Dyn'Aero's MCR 4S kitplane
The project
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 :
Photo GTH
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 !
To learn more
MCR 4S short takeoff video
Video GTH
Short takeoff of the MCR 4S during flight tests at Gap Tallard (LFNA 1986 ft), February 2005.
Two on board, 60 L fuel, 600 kg, wind calm, outer air temperature about 10°C.
Brakes on until takeoff power is achieved, then rotation around 85 km/h (46 kts) IAS.
English pages coming soon
Contrails ! is still mostly in French for some time.I'm busy translating one MCR page after the other, so check back soon !
