Back to the original question, ask those who have flown the actual aircraft in question speeds, technique etc. If it's a PFA homebuild go very carfull as there is no typical example of a type - they are all different.
I normally get used to the aircraft on the ground, make myself comfortable in the cockpit, try and make sure the engine has a reasonable chance of running reliably, then treat the first flight as a test flight I.E not out of site of the field, lots of slow flight including stalls, a couple of go arounds until I'm happy to put the thing back down - then gently does it...
It actually is quite fun,
