I am also a bit nervous about tip stalling as our flying site is a bit restricted to come in fast. My flying buddy has this Hawk with an edf set up. He has only flown it twice, the second time he ran out of battery but got away without too much damage. As you said I am aware about keeping up the air speed and hope the flaps will be effective for the landings. I am also mixing in a bit of crow with the flaps in the hope of reducing any tip stalling tendencies.
Will let you know when I have flown it.
