O.S. 55AX .55 Glow Engine w/Muffler
These motors are the "B O M B"!!!!!! Running these motors on a Hanger 9 Mustang P-51 MKII and a Phoenix Model Giles G-202. Talk about having fun in the air. This engine carries a tune like all my OS engines, set it then forget it!. Both engines have been running over a year now as a matter of fact the one on my Giles use to be on my Decathalon, which was still fairly new, only a few flights on it before I took it out and placed it in the Giles. Just bumped it with starter and she just purred away, awesome. If your looking for an engine upgrade for your 40 size airplanes, give the 55 a try, you won't regret it!)
