After a successful maiden flight the 64mm edf hawk testbed has a coat of paint and a few waterslide decals. The weight is now up to 1650 grams (including the 6s 3000 mah battery) so it doesn't float like a stock 3s T-45 but still flys well due to the 1500 watts of power and almost 2kgs of thrust on tap.
Since this is the testbed, I haven't sanded back the mold dimples in the foam or smoothed the foam out with primer putty.
The pilots are HK T-45 pilots.
The wings are still held on using the standard hardware. I am getting gamer with the positive G loads, but still a bit cautious with negative G.
During flight testing the hawk has proven to have a large flight envelope, but it really needs a rudder for the cross wind landings and flaps to slow it down in crosswinds. With a headwind on landing it slows nicely and floats in. In a crosswind it just does not slow down and takes almost the full length of the runway to stop

Here's the vid of my hawk maiden with the extreme rc 64mm alloy fan on 6s.
So far the mods are
-New fan unit
-MG-14 metal gear servos for the elevator and aileron (in stock locations)
-HK dsr retracts with 7075 suspension strus hot glued into the foam (Super dodgy, but that is intentional so I can see what I can get away with)
-1 6mm carbon strip in the wings and 2 x 3mm carbon strips in each stab
-stabs angled down by hot glueing a piece of balsa underneath to give the angle.
-All hardware upgraded to Du-bro (2-56 ball links for the elevator, 2-56 quick links for the ailerons)
I had to fly very carefully for the maiden because I was using the stock hardware to hold the wings on and was bit worried that it might not hold up. The maiden was just to prove that it could fly.
Big thanks to Trudge for shooting, editing and posting the video.
