Vortex 34" on 6S Speed guess?

[nate]

Running 6s on a Leo 2200kv, x438 prop. Have yet to GPS. Yesterday all it would do after half throttle was take flight, so I pulled the turn fin, propped down 4mm, and built two front wings to push her down. Did two passes in the video. Going back out tomorrow afternoon with an x442 and x445. Hoping to atleast see high 70's.
