At SERFI Flyin 2003, I took off behind Finn and immediately after lift off with perhaps 15-20 ft altitude (or less)  the aircraft roll violently up (45-60deg) with the right wing - and yawed approx 15-20deg to the left - subconscious reaction was stick/rudder full right - no immediate response, had time to think "control problem" when the aircraft reversed and rolled up  its left wing.  Scared a couple years off my fast receding youth.  Later decided it was Finn's prop wash and now make certain that the aircraft in front of me takes off on the down wind side of the runway or I simply wait until he has lifted off and cleared the end of the runway.
 
That small RV3 generated enough prop wake to roll my rather heavy RV-6 around like a toy.  Not nice close to the ground and slow on airspeed.

I was there too.  Made a REAL BELIEVER out of me.  Small airplanes do have wake turbulence;  Probably off the prop wake IMHO;  others seem to think wing tip vortices.  For those who weren't there:  at Tracy'sin 2002 (I think), Finn started his takeoff run soon after ED had lifted off; as he (Finn) 'rotated' the aircraft rolled left (hard) and the left wingtip lightly brushed the ground.  Scared me silly; Finn had no idea how close he came to ???????.
