Record the process with a camera and share it with you here. Although not very beautiful, but the most important thing is: "can fly."

Maiden voyage, the center of gravity is just right. After the third and fourth laps, the fine adjustment was completed. Before preparing the aileron to roll, the paddle was sprayed, crash landing. I flew this morning.

Three batteries, the overall performance is good. Last trip, turn it up, roll and so on. Compared with F 15, it feels a little unstable, sometimes it shakes a little (maybe my aileron is stuck in a little empty position), so it will look better when landing, unlike F 15, if it is not fixed, the leaves will float down.

The fuselage is 3mm pearl plate, the skin is 2mm, and the partition is 7mm (the stationery store marked it wrong, so I want to buy 5mm 7mm, which is cheaper).

Some places are not doing very well:

1. Don't stick the vertical tail first, stick the bracket of the flat tail first, and put the skin on it, not on it. It's better to put the motor rod on top, not on the bottom.

2. Level the line on the stern rudder surface. I guide it with a straw. This morning, a senior suggested that there would be a vacant seat and a thinner tube could be used.

3. I didn't do the horizontal tail down five degrees ... lazy?

Wingspan 60cm

The takeoff weight is 550g.

Look at this three-view picture. Make the fuselage first.

Add two reinforcing rods.

Behind the steel bar, add two 7mm pearl plates and one cm Takaso.

I always use hot dogs.

Add the wing skin, so that the wing is finished.

Sandpaper the leading edge of the wing and attach the glass fiber tape. Seal the edge with a suitable pearl plate (this was added later, and the order is a bit wrong)

Make the compartment on the upper part of the fuselage perpendicular to the tail wing.

Cutting the upper fuselage skin

Combined upper fuselage skin

Make a battery room

The battery room was covered, and it was later found that the battery was going forward, so the middle compartment of the battery room was later opened.

7mm pearl plate is used as the lower fuselage, and the motor is stuck on it.

Three pieces of 7mm are used as the nose, which is based on the previous practice.

This is a big area. I use styrofoam and then sand it with sandpaper.

Later, it was found that the flat tail was too soft. With the reinforcement, this should be added.

Add skin, and this should also be added.

Cut off the position of aileron

To make an aileron, cut this angle.

Add fiberglass tape and prepare for assembly.

Put it together like this

Aileron is ready.

Flat tail dare not make full rudder surface, and use-shaped line to link it. The suction pipe is too big to be improved.

Power on, using aileron hybrid control.

Use 7mm as the compartment of the lower fuselage.

It is better to stick the lower fuselage skin to the middle first and then to the side when it is dry.

Positive connecting rod

Grab the nose and do it well.

Make up the last F 15, which is a little beautified.
