First video was the maiden - needed lots of aileron trim and less throw on the aileron and elevator.  Second flight was much better.  Thanks to Ruby's help and persistence, not to mention his incredible, awesome, mind boggling  engineering, we got the second flight going!  

The plane will be quite heavy if you follow the plans.  I chose not to install the internal fiberglass ducting and saved some more weight in other places so it came in around 8 lbs.  As originally intended, it would have been 9-10 lbs which makes it not flyable!  There are many videos on Youtube detailing numerous crashes as folks get them airborne but destroy them upon landing.  BTW, this was my third such hawk - first two went in because of various problems.

re the BAE Hawk

Landing gear:

Speed Controller is a Castle Creations 120 HV.

The flight surface throws are much less than the manual recommends.  

I am using two 4S 4000 mah batteries, also from Hobby King.  I installed one in the battery tray and one on top of the wings in the fuselage.  I also had the CG more aft than where the manual recommends 120-125 from the leading edge/fuselage intersection.
