History of control line

Models on lines and flying in circles predate manned flight. Early versions merely constrained the model to fly in a circle but offered no control. This is known as Round-the-pole flying. The origins of control-line flight are obscure but the first person to use a recognizably modern system is generally considered to be Oba St. Clair, in June 1936, near Gresham, Oregon.St. Clair's system used a rather large apparatus similar to a television antenna, onto which many lines were attached. This system is very different from those currently in use on modern control line models.

The name most associated with the promotion of control line, and the inventor of the formerly patented system known as "U-Control" (which was a trademark, and is the system in use on virtually every two-line control line model today) was Nevilles E. " Jim" Walker. His "American Junior" company was by far the biggest producer of models, and held numerous patents on the two-line system until overturned during a patent infringement suit, by Walker, against Leroy M Cox, based on "prior art" from St. Clair in the 1955 trial.^[4] One of the most coveted prizes in control-line aerobatics competition sanctioned by the AMA, awarded to the winner of a flyoff between the US Junior, Senior, and Open age class Champions, was originally provided by and is named for Walker. This is one of the oldest perpetual trophies in modeling that is still awarded.

world Championship 2018

The well-known control line stadium in Landres in the east of France will receive these world championships, as it did in 2000 and 2008.
Every year the club organize on this stadium the Netherlands and French Grand Prix, which are World Cup events. This site is totally ready to receive such a world event.

Permanent circles for F2A /F2B/F2C and F2D exist, with permanent score displays (F2A and F2C). Training will be organised on the spot for F2A and F2C, and on football places in the town of:

• Piennes (2km)
• Mercy le Bas (6km).

An amazing person - Amit Shani.

The stabilizer made of balsa 4 mm with hollow profiles 

and 1.5mm steel coating on both sides.

The process of building a wing

*Post updated course of work*

I chose this profile Profiles Template

Profiles Template

Preparation of profiles:

Then use a new method to create a very good profile.

and cutting aluminum for profiles template.

For profiles I've used with balsa 1.5mm 

Location profiles in the mold

 13 profiles for each side

 Unfortunately no pictures of the process of refinishing and cutting of profiles...

---------- 

After refinishing of profiles.

Final result.

In conclusion:

I highly recommend this method of preparation of the the profiles only if your profile is symmetrical,

Because it is very accurate and easy to work

I think the most correct method creates a profile symmetrically equal on both sides.

wing:

Placing the profiles and test measurements.

Continued work and testing before gluing.

 Placing beam and flow edge.

Continue work on the wing.

I chose a steering axis of sig.
