Resistance to Turbulence

[jchronic]

On our marine mammal surveys, we frequently circle in place for 20-30 mins at a time at 30 degree bank angles, so in light/no wind situations we regularly encounter our own wake. Last year, using a 'straight' 337, we got some pretty good jolts after several circles. This year we've been using a 336 with a Robertson (Sierra) STOL kit and the whole crew seems to think the wake turbulence jolts are much milder than last year (in the 337).

Strictly anecdotal and I wouldn't attempt to explain it aerodynamically, but thought I'd offer the info. In any case, I seriously doubt it'd be worth the cost of a conversion for whatever improvement there might be in the ride.
