As for pitfalls and differences, the Aerobats are exactly the same airframe but for stronger wing spars, bigger wing struts and beefed up tailplane spars. Some 150s (the FRA 150 L/M/N) had a RR O-240 130hp engine which is 30% more power than a standard 150 and 15% more power than a 152's O-235 Lycoming.
