Funny thing about that Pilatus...On aero tow, during ground roll and take off, you HAD to hold full forward stick....if you didn't hold it to the stop, the glider would take off and continue to climb, and then full forward stick would be useless...it would just keep climbing....You had to hold the stick forward, and do the ground roll in a nose down attitude...and it took off in that nose down attitude too....I guess the wings are rigged with a high angle?

Other wise really nice glider.

That sounds like there was a real problem with the CG or stab/elevator rigging (or the wing incidence?) on that particular B4. Long ago, I flew a couple of B4s (no, actually, it was the same one in two different places, Vacaville and Estrella, separated by several years!) and other than pitch being a bit sensitive (kind of like a 1-26), it otherwise was an easy plane to fly. Definitely did NOT have to hold the stick forward for takeoff or tow!
