My GP CE has a DA-50 and weighs 18lbs. Its a great flyer and lands much better than previous CE's. It's a real tumbler and stable in the air.
My buddy has the GP Patty with a BME 50. Again this bird is a great flyer and stable on landing. Lands just a hair slower than the CE.
I've flown both and can say..... You are going to have problems trying to decide. The CE is heavier but is a head turner. They both look great. Time to flip a coin!
