R-3LD, PS-3 by A.N.Tupolev

41k b/w R-3LD "History of aircraft construction in the USSR", Vol.1 p.369

During construction an trials of R-3 variants about 100 French-built 450hp 'Lorraine-Dietrich' engines were purchased. Installation of this engine on R-3 allowed to improve aircraft balance (moving CG forward) and gave aircraft more power.

Construction and flight trials of the pre-series aircraft were completed in June 1927, and new R-3 variant was put into production as a R-3LD (LD for 'Lorraine-Dietrich'). After minor refinement R-3LD production was launched at '10th Anniversary of October (revolution)' Factory.

Until Summer 1929 79 R-3LD were built. One was transferred to Aeroflot under designation PS-3. It served in Yakutia as a mail/newspaper delivery aircraft.
