Construction:
1. Stick the 2 pieces f main wings symmetrical with 502 glue.
2. Put 2 pieces f carb n r ds with 990mm length and 2mm diameter int the sl t f
aircraft wing's t p and b tt m surface.
3. Stick the tw carb n r ds in the t p and b tt m t the aircraft wing with 502 glue t
enf rce the aircraft wing's strength.

4. Put 2 pieces f carb n r ds with the length f 780mm int the sl t f fuselage's stiffener,
pay attenti n t the right and left directi n.
5. Stick the stiffener t the b dy f aircraft with f am glue, the fuselage sh uld keep
straight.
6.. C nnect carb n r d with stiffener with 502 glue after the stiffener has been adherent t
the fuselage firmly.
7. Check fuselage t make sure it is straight bef re the glue s lidifies t tally.
8. Insert the aircraft wing int b dy f aircraft ( as illustrated in the picture ) .
9. Bef re sticking the t p surface t the b dy f aircraft please check the right and left
p siti n f the aircraft wing t see whether they are symmetrical.
10. Stick w d strips f landing gear with 502 glue, please make sure the sl t f r landing
gear sh uld be kept upward.
11. Stick the w d access ries f the landing gear t the fuselage with 502 glue.
12. Dr p the 502 glue int the juncti n f l wer surface f aircraft wing and the b dy f
aircraft.

13. Put 2 pieces f l ng w d strip int the 330*4 sl t.
14. Stick it with 502 glue.
15. Put the h riz ntal tail int the fuselage and stick them t make sure they are
symmetrical.
16. Assemble the main aircraft wing and h riz ntal tail c rrectly, and make sure A=B as
well C=D.
17. Stick ne plastic serv h rn t the vertical tail with 502 glue and make sure the
distance between serv h rn and the l wer part f the vertical tail sh uld be 92mm.
18. Cut a sl t in the edge f vertical tail with craft knife, insert half-size f the 4 pieces f
paper hinge int the stick, then stick them with 502 glue.
19. Cut a sl t in the fuselage after insert the paper hinge, stick them with 502 glue.
20. Stick the plastic serv h rn t the p siti n illustrated in the picture.
21. Cut a serv h le in the fuselage and make sure the serv h le is at a distance f 13cm
fr m tail angle.
22. C nnect serv c nnecting r d carb n r d t steel wire with h t shrink tube.
23. Make sure the angel between c nnecting r d and serv arm sh uld be vertical. After
adjust the length f c nnecting r d, dr p 502 glue int the seam f h t shrink tube t stick.
24. Stick the w d strips f m t r m unt with 502 glue.

25. Inset the head f fuselage then stick it with 502 glue. 26. Put landing gear steel wire
int the h t shrink tube after it fixed with wheel, then stick the tube with 502 glue.
27. Insert the landing gear int the fuselage, then insert the w d stave int the se<am
then stick with 502 glue.
28. Fix the m t r t Plyw d M t r M unt with self-Tapping Screws.
29. Refer t the p siti n f receiver
30. The centre f gravity sh uld be 120-130mm fr m the fr nt edge f aircraft wing.
31. We suggest that y u add 1- 2 degrees f right-thrust, which can be achieved by adding
ne washer r tw behind the t p and right side f the m t r (between the m t r and the
m t r m unt). When set pr perly, the trim f r the elevat r and the rudder sh uld be
neutral. Fine-tune the d wn-thrust and right-thrust until this trim is achieved. When d ing
flight test, we suggest y u sh uld keep the flight balance acc rding t the centre f gravity
we rec mmend. When d ing 3D flight test, y u can m ve slightly the centre f gravity
backward.
General flight: Ailer n: 20 degrees, Elevat r: 20 degrees, Rudder: 20 degrees.
3D flight: Ailer n : 45-55 degrees, Elevat r: 45-60 degrees, Rudder: 45-60 degrees.
Seek Assistance: If y u are a beginner in the R/C field, we suggest y u turn t an
experienced pil t f r help with the first few flights.
