R/CModel airplanepageSuper Marine Spitfire MK II
                                                                          Create :   2012 - new update 12 Aout 2016
  Super marine Spitfire MK II 
  Wingspan : 67 inch ( 1680mm ) 
  Length      : 48 inch 
  High wing air foil NACA 1212..
  Weight     :  7,6 lbs
  Engine : 61- 91 Two cycle Nitro engine   
  Contruction  : All wood air frame & thin layer solar film covered .
  Radio  :  5channel
   The difficulty to build the SuperSpitfire is it wing .The origine airfoil of the supermarine spitfire Mk II is NACA 2213 with a thickness-to-chord ratio of 13% at the root and reducing 9.3% at the wing tip  The dehydral angle are 6 degrees .I decide the NACA of my Supermarine Spitfire was 1212 .. and reducing 8% at the wing tip, dehydral angle was  3 degrees  . More light , strong material had been  used to contruct  this model airplane ;but the balsa wood is usually the good materiel to made it. The contruction of this aiplane is all balsa wooden air-frame;  covered by thin black car glass solar film with enamel army color paint  . The second difficulty of this is the retractable gear ( see on the  next )   . 

 Wing : Was an  980 square inch  and  all wooden contructional wing .The wing- airfoil  is  NACA 1212 reducing 8% the thickness-to-chord ratio at the wing tip . The two aileron system ( see figures ) .are independable . Each control by one 3,5 Kg servos , installed hide into the wing .The hinges of the aileron are fourth piece of x ray film and installed at the middle of the rear wing bar . More hole in the wing foil lamina was reduce more the total weight of the wing . All covered by  black glass-car solar film and high enamel color paint .

 
Fuselage  :The main contruction of the fuselage is all wooden air-frame with four main bar 7/7 x 120 of epine hard wood ( see plan )  . The standing of nitro engine is alumium standing engine or hard wood standing deck fixed on two layer of plywood ( see pic ). Down 2 to 2.5 degree and 1,5-1,7 degree to the right of the engine axis are  require  .The fiberglass canopy and wide sufficement opening air intake had given a very good form and firm mouting (see pic ) .

    The attachement of the wing to the fuselage is  eight long screew fixed to the fuselage ( see pic )
 Engine  : You can use the engine from .61-91. The 61 ASP nitro engine and 45 degrees right down was choice . To augmente the power of this engine , I change the standard muffler by an new type muffler ( see pic )  , and by this I can use the 13x6 propeller with any trouble
             

Gear system : This was a scale retractable gear which i can do ( only one in R/C airplane world ..) . All contruction is stainless steel tube , sprintable and solder by high plasma argon sold -tech . Thirty degrees external and back into the wing when retracted . Eight degrees in front and fifty degrees on exterior with the vertical axis when the gear was down . The choice of the angle of the wheel axe was a simple  mathematic solution .. ( see pic ) . Retract activity of the gear dominate only by one servos 10,5 Kg installing on  the middle  of the wing ( see pic ).

 

R/C system , servo & other  link installation : Four 3,5kg-servo for elevator , rudder , aileron & one mini servo for throttle-valve  . An 10,5kg  servo was using for retractable gear   . The  battery are fixed in high , middle of the fuselage and adjust for the CG ( Center of gravity ) at 25%-27% from the front of the wing cross section . The receiver was place on the highest of the fuselage in the pilot copit and sticking on the base of a rubber foam-sheet for reduce the vibration of engine and the shock ( see pic ) .

 
  The rudder and elevator's rod are two 2/8 carbone rod tube with two 2/32 steel wire fixed at the end ( see pic ) . These are light , hard and had any trouble in working Rudder , elevator , aileron adjust & flying test : Up 2/3  and down 1/3 inch for elevator . Right 3/4 and lelf 3/4 for rudder and 1/2 inch for the aileron . On the first fly , reduce some in the angle-effect for the aileron an elevator and slight trim down on elevator ( on the first test flight ).
      On a clear and calm sunday morning , I  made my first flying test ......
