TT E720 - 690 blades or bigger

[Si Goodchild]

Guys,

What is your opinion on the optimum blade size for the TT E720? Some folks fly with 690mm blades, but the arrival of the E700 (which flies on 690mm blades max) makes me think that 710-720mm items may be more appropriate on the bigger machine. I fly 710mm RADIX blades on my electric Raptor 90 and 690s on my TREX 700N and both are perfectly suited to the host machine so was wondering what your experiences are?

I should probably add that I don't fly aggressive 3D, but big (often fast) aerobatic manoeuvres.

Longer heavier style FAI blades if you fly bigger air stuff and don't thrash it around Simon.
