Finally finished Falcon 120 and ready for first flight, fingers crossed. I have carried out all the mods mentioned in this thread. Formers re-glued with Hysol,

WINGS
The cardboard wing tubes have been soaked in thin superglue, along with one large tube poured into each wing to strengthen all joints, making the flap and aileron servos flush mounted helped to gain access, I also poured Godzilla glue down all wing joints, so the wings should be good and strong. The nylon securing bolts where replaced with metal studding and I used wing nuts to secure the wing, the front dowel was replaced with an MFI cabinet lock nut and stud, the type used to fit kitchen units together, the locking nut is fixed inside the fuselage and it pulls the leading edge in nicely, The aileron and flap servos are Hitec 7475HB, with the flaps programmed for slow speed, and Ashlok 12 way connectors to connect the wing wiring to the fuselage, and a 6 way to connect the booms, the front alloy spar has been replaced with a 10mm solid carbon rod.

Booms
All inside covered with thin superglue and Hysol, tail section covered in Aluminum to act as heat shield, servos Hitec 5345mg used on rudders and elevators and all servos moved to the inside with ball joints and carbon rods. Connection to servos through 6 way Ashlok connectors.

FUSELARGE
All formers removed and the two rear formers shaped to take a 2ltr coke bottle (intend to check and replace regularly), two new rear formers made to shape of coke bottle and covered in fuel tubing to help prevent wear on bottle, these are screwed to existing formers for easy removal. New tray made to take electronics ect. All the fuel fittings (pump, header ect ) located in rear with two alloy vents on bottom of fuselage to drain fuel should I have a leak or burst tank. Then belly was covered in 2� carbon cloth as I’m sure you could poke your finger through it, The rear turbine tray is supported by aluminum angle (page 82), thanks Boomerang1. I made two thin ply cases (with holes in) to take two 2200 7.4v batteries, the cases are glued in and the batteries slid in and are held by valcro for easy removal. Inside painted the same as SJN’s (page 55), and looks very professional.

Undercarriage
The retracts where supplied by Wholesale planes and fit very well, came complete with tank, valve, gauge, piping ect all for only 60 pounds, the main legs might need to be changed and where made out of two paint rollers from B&Q 6mm chrome spring steel, and the wheels from Motors and Rotors about 4 pounds each, better than paying 382 pounds at the moment for Pro-Lynx setup, but I might have to go this way later.

Turbine
Wren 54, no problems fitting and just used wooden blocks supplied, and made 5 degree down thrust and fixed in place with 4mm steel studding, four gold bling nuts secure it.

Parts used
Futaba 2.4ghz 8 channel receiver
Two 2200ma 7.4v Lipo Batteries
One Flight Tech 8amp regulator supplying 5.8V
Bvm air trap
Ailerons / Flap HS 5475hb
Elv / Rudder HS 5245MG

Throws C og G 13�
Aileron low = 20mm, high = 25mm
Flap low = 20 deg, high = 45 deg
Elv low = 15mm, high = 21mm
Rud low = 30mm, high = 30mm

Looking through the thread I think everything has been done to make this plane turbine ready and the control throws should be ok, but let me know if you thing I should change them before first flight. Just waiting for the weather to warm up a bit so I can do more than one circuit before my fingers freeze, still cold up here in Lincolnshire, Will let you know how I get on.
