7ECA vs 7GCAA
I, with partners, own a 1974 7ECA 115hp and a friend and her husband have
recently purchased a 2002 7GCAA 160hp.
I had the opportunity this weekend to fly each of these aircraft and have some
observations;
7GCAA leaps off the runway much quicker and climbs at around 1200fpm initially.
The 7ECA takes probably 3 times the runway to get off and climbs at about 7-800
fpm initially.
40 degrees F and me and 3/4 fuel.
7GCAA cruises at 2,000ft at 2400 rpm at 120 mph indicated.
7ECA cruises at 2,000ft at 2500 rpm at 105 mph indicated.
They both land the same.
When doing a loop, I have to dive to get 140 mph entry speed and the 7GCAA takes
less altitude to do this so it ends up using about 200ft less altitude to do a
loop and the extra power makes a difference over the top.
I am not a test pilot and am a self taught aerobatic pilot so my observations
are just that. Your mileage may vary.
I still like my 7ECA even though it takes about 3 times as long to get back to
altitude after a maneuver. The 7GCAA is a reeeealy nice airplane.
