<div style="margin: 0in 0in 0pt"><span style="font-size: small">In my opinion you should invest in OS 55AX, because later when you will be finished with your training on trainer, you will be able to use this engine in any respectable patternship aircraft for further advance flying in your career. Because in an aerobatic model you will need an extra power for advance maneuvers which 55AX can provide but will be difficult for 46AX to pull those maneuvers.
