Kawasaki ki-61-1 Hien. Radio control scale fighter model. For 20-25 power.

Plan includes build instructions in Japanese and English.

Quote: "Ki-61-1 Hien Construction:

1. Fuselage:

a. Construct right and left fuselage sides. (See drawing #1 on the plan.)

b. Construct the fuselage frame by setting inplace the keel pieces F-16--F-19. (See drawing #2 on the plan.) Next trial fit pieces F-2, F-3, F-4, F-5, F-71 F-9, F-11 and F-12 into the notches on the fuselage ply doublers, while at the same time install the pieces F-13 ~ F-15 onto the keel F-16, then glue F-5, F-7 and F-11 to the inside fuselage ply doublers. Next install F-17 ~ F-19 and then install F-8. Now glue the rear fuselage sides together as well as F-16 and then add pieces F-13 ~ F-15. At the proper time, add F-6. Construct F-10 and F-10A as per drawing#6. Now glue the 3x5mm balsa horizontal stabilizer area reinforcers. Also the antenna bat; pieces F-18 along with scrap balsa on each side of same.

c. Add the 2mm cockpit and tank compartment floor. Use the die-cut 2mm sheet for the fuselage side sheeting. When sheeting the lower area with F-41, add the F-33 piece. After sheeting add the 3 x 10mm balsa plank to the inside of the cockpit area as per drawing # 3.

d. Tack glue F-34 and carve to the final shape. Then as per the drawing shown (#10) assemble the tail wheel pieces, then cement firmly in place.

e. Nose area construction: First, trial fit and then glue EM1 and EM2 to F-1 as drawing #7 indicates. Space the engine mounts depending on the engine used. See notes next to drawing #7.

f. As per drawing #8, cutout F-20 as well as the right side doubler for engine clearance. Now set in place the engine mounting screws.

g. As per drawing #9 add cowl blocks F-22, F-21, F-23, F-24 and lastly F-25. Then carve to the final shape.

h. Sandwich two F-29s and make the wing fillets. See drawing #3. It may be difficult to bend F-27 so it is recommended that it is wetted with water to make it bend easier.

i. As per drawing #4, add F-32. When installing F-32, Cut out F-33.

j. Construct exhaust stacks as per drawing #5 . On the right side, add only the last three stacks for engine clearance.

k. After constructing the horizontal and vertical stabilizer, and as ner drawing #11, cut out R-3 to clear the elevator horn. 1. Shape the antenna and install same, and also install the canopy. This completes the fuselage construction.

2. Stabilizer:

a. Construct the horizontal stabilizer as per drawing #16on a flat surface. Install the 3x5mm balsa ribs at the locations shown on the plans. b. Shape the elevator and Stabilizer as per the top view.

3. Wing Construction:

a. Construct the center and outer halves of the wing separately. (See drawing #12) Make rib location as shown on the plans. W-1 and W-2 are doubled. Make two assemblies.
b. Cement together the outer and center wing panels. (See drawing#13,)

c. Add landing gear blocks W-12, W-13, W-15 and W-16 (When using retracts, use W-13A, W-14 and W-17) and then glue in W-28.

d. Sheet the upper and lower areas of the center section with 2mm balsa sheet. Then glue in the 2 x 18mm balsa stock to the trailing edge and then sheet the upper and lower areas of the outer wings with 2mm balsa sheet. See drawing #14. After the sheeting is complete and the 2 x 5mm balsa cap ribs.

e. Add W-18 and then set in place the aileron horn and then finally glue in the trailing edge.

f. Route out W-26 to clear the aileron torque rod. (See drawing#14.)

g. After installing ailerons, shape W-18 to its final shape.

h. As in drawing#15, glue in W-27, add the wing hold down dowels, and then cut out the holes for the wing hold down bolts.

i. Add F-31 while attaching the fuselage and then finally line up the wing with the fuselage..."
