RE: P05 vs P07
With my setup (Hacker C50 XL14, 1:6,7 etc, Polyquest XP 2500 2p10s), I have never had a problem to make the P-05, in any kind of (legal) wind. With P-07, in wind, I sometimes lose power before/in the last maneuvre (hexagonal loop). I charege to 41V though, for the sake of the pack lifespan. Charging to 42 for competitions, I should be ok, as it means some 8 to 10% extra charge. But still, it is a little bit worrying.
TonyF, I think that P-07 is strange too. Or rather ugly and not difficult enough... given the ever improving skills of the average F3A pilot.
P-05 seemed better balanced to me.
