Actually, the bigger the model the less wind affects it. A plane that big with that much wing area and power should have flown fine in the weather I could see. IIRC, the engines (Wren Turbines) cost about about $3500 x 8 but were donated by the manufacturer because of the projects publicity. These planes especially the jets when this big have TONS of wireing, 20+ servos are not uncommon as are multiple recievers for differnent functions, then you have air and or hydraulic systems for the gear, bomb bay doors, fuel pumps, mult battery packs, gyros etc etc. A pinched wire, dead battery,binding control rod or cable, etc can spell doom.
What kind of reaction would you expect? The guys just saw years of work go inthe shitter, they were probably in speechless awe.....
