Cessna 150 scratchbuild + Trainer mods

Hi everybody!

This time i want to tell you guys how i made this plane, a CESSNA 150, a plane i always wanted to build from scratch, but no very scale, because as the Piper J-3 IS NOT a trainer, with no dihedral wing, and kind of "short tail section" that makes it no sooooooo steady as you wish in a trainer.

So, the objective is: A Cessna looking plane, as scale as i could but with a trainer flying characteristics, with a gentle and docile flight and a good performance too.

To accomplish this last items the original Cessna design should suffer some modifications: Enlarge the fuselaje section behind the trailing edge, increase the wing area, and increase the dihedral for better self-stabilization behavior. 

Here is the building video and the first flight, as always in a windy day:

Also, i have in mind few common characteristics of the trainers as: strong building materials, reinforcements, tricycle landing gear, and rubber bands to fix the wing in place.

Specs:

Wingspan: 1230 mm

Length: 960mm

MTOW: 745 Grs.

2830 - 1400 Kv Motor

3S 1500 mAh 45C Battery

9x5 Propeller

30A ESC

The fuselaje is a classic but reinforced box-shaped structure:

Here is the foam/plywood main spar:

The stabilizer is a made of depron 5mm as the rest of the plane, with two plywood / pop stick spars :

To reduce weight, and make it easy the electronics installation i drill few holes with a old Gas plane spar but you can use any metal tube sharply enough.

Here you can see the reinforcements in key parts to make it hold the hard handle of a beginner pilot, where the wing lays, behind the F1, and all along the fuselaje sides:

As always do, i tried a new technique to cover the plane, with laminating film painted with Rustoleum spray paint, an important tip: Paint the inner side of the film, later the heat will do his work anyway.

You can see how smooth and shinny is the result:

The plane needed 30 grs of ballast in the nose to flight better, in the second flight improves the handling characteristics

In the end the result was very good for a scratch plane, even the wheels are made from scratch, old flipflops hehe.

I hope you like the plane and find the tips useful !

Until next time!
