Combines N SERIES OR R SERIES

The early N series had many problems as did the rest of the early Rotary combines. The SERIES 3 N's are identical to the R's. All the fixes were in by 1982(Series 3) and the R5_6_7 are the same, just renamed by Deutz until the Deutz engine was put into the R40-70's. The most noticable change of the N's was the Ambac fuel system and slowing the engines down.(Series 3)

Don't know difference between N's and R's, but I traded a F-2 long body on a R-50 and there is no comparison between the two, you can do at least twice as much in a day. Tried a R-40 also and it is a big step-up also!

I'll second the R50. It would be at least twice what an F would be. Also, the R50 was the forerunner of the 2 series (R42, R52....) so they are much simplified and steamlined compared to the N series and the later R series, (R5, R6...)
