Fei Bao Mirage F1, Assembly Manual

3.

Wings.
Epoxy(or use Hysol glue) the control horns into the 

control surfaces. Also do the hinges (Apply Vaseline to 

the pivot points to keep the epoxy or Hysol out). Trial 

fit them and check adequate amount of movement available 
and epoxy in place.
Fit the servos using the brackets and screws supplied for 

the flap servos. The aileron and rudder servos are 
epoxied to the hatches(This method has a disadvantage if 

servo maintenance is required later!!) Make sure the 

servos are centered and fit the servo horns. Check the 
length of the control rods and adjust as necessary. The 
clevises are at the servo horns and the ball fittings at 

the control surface horns.To avoid the rods from working 

loose “lock” one of the threaded ends by applying epoxy 
or metal epoxy to the thread. The other end can then 
still be adjusted if required.

4.

Elevators.As this aircraft is equipped with all flying 
elevator a failure can easily cause a crash. That is why 

at least 25kg torque servos are required.I suggest to 

reinforce the former inside the aft fuselage where the 
elevators attach with epoxy and carbon fibre to eliminate 
any flexing in this area especially if you like to fly 

fast!! Make a baseplate from 5mm plywood sanded to the 
contour of the aft fuselage where you plan to glue the 

servo. Fit the ball fitting to the elevator horn and for 

additional security also add a nylock nut behind. Fix the 
servo to the baseplate using epoxy and hardwood blocks or 
metal fittings. Make sure the servo is centered and mark 

the approximate position of the horn on the side of the 

rear fuselage. Epoxy the whole unit in place. Attach the 

rod and clevis or ball fitting at the servo end. Apply 
threadlockerwhere applicable as a failure of the elevator 

servo will cause a crash. Make sure the movement is full 

and free. Use a spacer on the rod between the fuselage 
and the elevator if needed. Tighten with the 2 hex screws 

and don’t forget the threadlocker! Use aluminium tape to 
protect the servo leads running forward towards the 

receiver.

5.

Fin and rudder. Epoxy the control horn in place and the 

hinges as with the wings. It is difficult to get the 
rudder into position due to the sweep and I cut away a 

square at the base side of the fin to allow the rudder to 

go into position. Also use Vaseline on the leading edges 
of the rudder to avoid it getting stuck to the rear of 

the fin!! Trial fit before doing the real thing. Test the 

screw that fits into the forward fin attachment shaft
