SSD
I have a goodly number of Pitts hours both S2 and S1 and a couple of hours in a 52. IMHO,the Pitts is an arial motorbike, strap iton and go, thing roll and it rolls, the whole lot more or less with the fingers of one hand. The 52 I found very heavy, a two handed job, especially in snaps and through inverted. You could say it was a man's machine, big and butch and very agricultural, but the fact that there are none at aero contests after about Standard level must say something. 52's are probably fine if your mission is to pretend you are in a fighter over France, but if you want serious aeros, buy a Pitts.
