RE: Skymaster BAE Hawk

I own and fly the "old" version and will comment on the "pitch-down" tendency when using flap.
Recently whilst flying my Hawk at Temora Jets I experienced this problem for the first time. It was very scary! Thankfully I was high enough and had time to retract full flap, before recovering to land safely on first position flap.
Basically the Hawk (mine is 13.5kg without fuel) is a floater and will land very easily. It is also deceptively fast, so deploying the flaps too early are easy. I've had many flights with mine up to that point and have always paid attention to the speed - but I got caught. I think the main problem was flying together with a lot of other jets and having to stay in the "pattern".
My advice, be on your toes, don't deploy full flaps to early.
That all having been said, it's a wonderful model.
