YES
I was thinking the same thing myself. I also can't remember the last time I flew a Beaver that wasn't in the air at 60 knots, except maybe waaaaay back in the Red Lake days on so called "company trips". or when I forgot my flaps ; (
If your taking off in a Beaver and you have to turn 90 degrees to get airborne what the hell are you doing there in the first place and you definately shouldn't be there for any training purposes. The best policy for ski work is land, stop and take off straight ahead. Majority of "F' Ups" always happen when you start screwing around on the ground in a tail dragger, especially when your relying on air rudder and brakes to steer. Just my opinion.
