Today I made 4 flights. Two with the delta hub and two with a standard hub. Actually I used the same hub but with two flights I removed the tiewaps and allow the blades to seek their own positon. If there was a difference it was very slight. If anything the gyro got off the ground quicker when I allowed them to swing straight out to seek their own position. I was using the molded SG6042 profile blades.

Has anyone else done a comparison. The delta hub didn't seem to contribute anything in my experiment.
