Well grass was no issue at all even with it being a bit long and wet. She handled It all very well.
In fact on the second flight I had a flameout in the worst place possible low and heading upwind, close in, but she glides so well I had time to do turn away 45degs then all the way round and land down wind (5mph so no worries). Probably 50foot (ish). Biggest learning from all of this is don't use full flap with no motor! Take off flap is just fine for this situation.
I'm so glad I decide to go for this model (Thanks Colin for the suggestion)
