Another VectorFlight fan here! Definitely worth it! Loved my Extra 58 before retiring it after several years of great flying. Now it’s the Edge and Extra 66, both with 91FXs. Easily two of the best flying airplanes I have owned in this class. Excellent for IMAC or unlimited aerobatics, penetrate head and cross wind nicely and track true and precise. Hardware is USA made standard, no cheesy stuff here, and in terms of overall quality what you would expect from much pricier stuff. The instructions are not for beginners but assembly is easy and they went together well without any hitch. Been thinking for a long time about installing my Surpass 1.20 on one of these birds, but just having too much fun with the 91s.
