DR.253


By 1965, it was time to replace the DR 1050 and the DR 100 series was succeeded by the Robin DR 200 range of aircraft, being very similar to the DR 100's. The DR 200 series started with the DR 220, of which 83 were built in 1967. The 220 was eventually given a 108 hp Continental O-235 engine, instead of the original O-200A, and was then called the DR 221 Dauphine. The Dauphine was later given a 160 hp Lycoming O-320-D2A engine, making it the DR 250 Capitaine.

After winning the Sicile races with the DR1051, Robin wanted something even faster. In an era where improvements in General Aviation were following up very quickly, the 6 year old design of the DR1050M was becoming obsolete. Robin fitted a larger engine to the DR1050, made it more roomy, streamlined it even more and thus created the DR250 Capitaine.

As a modified and improved DR 1050, the major changes were:
Larger engine
Wider track for main landing gear
Flaps
Floating tailplanes (again like 1050 M)
More streamlines around the nose
Slightly more tilted, larger windscreen
More shoulder room due to more arched side screens
Bigger, more comfortable seats
More comfortable as a whole
More sophisticated instrument panel that was taller and farther away from the pilot
No front/rear tank configuration, just a single, large tank under the rear seat, containg 70 liters and two 40 liter tanks in the wing roots
Smaller, wheels (5 inch rather than 6 inch items) and wheel pants, which are unfortunately a bit less well suited for grass runways.

The 250 proved very competative in the Sicile racings, securing the first seven positions in the rankings, Robin as always firmly on the number one spot. Robin experimented with a 180 hp engine in his personal DR250, with which he obtained an avarage speed of 317 kph during one of the Sicile air races. Such was his lead, that the race organizers asked Robin not to enter the next race, since this would render the rest of the field without chances of winning. After some 100 DR 250 were produced, the DR 250 was later given a larger fuselage, trigear undercarriage and a 180 hp Lycoming O-360-D2A, making it the four/five seat DR 253 Regent, appearing in 1967. The first Robin with a nose wheel.
