Magnum Engines XL 91 RFS Blue R/C 4-Stroke Engine
- Product Review (submitted on June 21, 2012):
- I have had several magnum 2 strokes over the years all were good performers. This is not my first 4 stroke but my first magnum 4 stroke. My 91RFS is in my hanger9 Fokker DVII and it runs great. Running 10 % with a 14x6 wood prop about 15 flights . Love the sound and performance. Can't beat how easy to operate these engines are.Would definitely recommend any of their engines.
