Review by Fletch88 on 19 Sep 2017review stating My Favorite Engine(s)
I bought one of these brand new since my first experience with glow engines was bad. I wanted to see how an OS was supposed to run, as I had always been told they were the best engine made.
I ended up buying a second one in like new condition for my U Can Do after flying the first! The sound is AMAZING! I love these powerhouse little engines. I fly at varied throttle for 10-12min each flight and only use 6-8 ounces of 15% Nitro per flight. I cannot say enough good things about how well these run and the unlimited vertical on a 60 size plane.

Review by Lugga on 18 Jun 2019review stating Rock Solid
I’ve had this engine for 11 months mounted on a built from scratch low wing 60 size stick. It’s swing an APC 13x9 prop and “Betsy” flies beautifully. She will do anything I ask. Knife edge all day, Lomcevak, almost endless vertical rolls. You can’t go wrong with the 95V. The 95V is expensive, but it will not disappoint and delivers rock solid performance.

Everyone knows O.S. makes quality engines. This is my third O.S. 95v. It's a great four stroke engine.
