Negative on the 'too much elevator' loco....the guy I had maiden it is mucho excellent pilot.
If you listen closely, you can even hear him say during the flight, "You've got serious outa balance goin here man". He knew right away it was balance problem. Luckily, he was able to set it down softly enough to not cause serious damage. I think I'm gonna take canopy2k's advice and rebalance starting at 100mm. Good luck on your maiden at 120mm,...I'm crossin my fingers for ya. Let us know how it turns out.
