R-3BMW by A.N.Tupolev
One of series R-3 was tried with 500/730hp BMW-VIz engine. It was flight-tested during 1928- 1929 and performed very well. Nonetheless airframe of R-3 was pushed to the limit of its strength. Limited fuel volume resulted in substantial range loss also.
Aircraft did not enter series production. Trial results were used in larger ANT-10 (R-7) design.
