Many DIY flying projects require professional composite manufacturing.

• hull and supporting structures of unmanned aerial vehicles (UAV) and ultralight aircrafts;
• frame and truss structures for optical instrument making for ground, air and space use;
• carrying and supporting structures with increased requirements for stiffness, strength, low weight, dimensional stability.

• our own R&D department with qualified staff;
• processing of metals and wood on CNC machines;
• production of composite products in various technologies.

 The quality management system for the design, development and manufacture of products from polymer composite materials meets the requirements of ISO 9001-2015.

Hi gang :)

What can I say?
Time passes, progress does not stop. And I finally switched to complex composite structures in my planes. Now balsa and film are reserved only for my hobby models ...

Time to move forward!

If someone needs help or professional service - please contact me.

Finally, we flew a latest plane - Primus III.

In one of test fly (engine stop in air)  I set new personal glide record: distance 976 meters from 68 meters altitude.

Hi gang :)))

Time to update blog. Story, named "Primus III". Prewiously, I show fuse building process:

Give me a fulcrum...

I'll go sleep now, because of my injury is less.

 Now, plane look much better. We make a trial fit all elements together.

and I'll take any twist. :)))

Remember me? I'm still here!

Began sheeting Primus III fuse...

Week end. Friday.

Primus fuse remove from building slip.

Looking small, but still have over 2 meters. :)

Where I've already seen...

A long time ago...

When computers were large...

I build a plane, called the Primus. But this was not the first Primus, first gone forever.

And second...Second crash too.

So, time to build Primus again, third reincarnation?

After previous plane all look really small.

What mammi says? Son, always check with a dry fit!

Coincidence? Glue it!

Uff...All dirty jobs are done. Trial fit, nearly 9 meters.

Now - clean, sand, spackle, prepear for covering...

Some time we need to work with metal parts. For example - motor mount.

Is a vibrationless motormount for MVVS 152 cc twin spark engine. I think it's possible made from wood, but aluminium look much better for me.

Photos only...More about progress in build later.

Friday... This week progress. Only photos, any comments.

Monday - day heavy, as you know. So long as any work starts on Monday. So I have - apart from today started sheathing wings.
The technology is as old as aviation. Or perhaps older, is not competent.
First the pattern.

On pattern ply cut, mark up, skins and throw wet.

And we go to dinner. And after dinner with various gums, tapes and other improvised equipment fix ply to the frame of the wing. And leave to dry for tomorrow...

First, load the fuselage to an inability to move. And then begin to glue stringer requiring moving the fuselage.

Friday morning

Friday evening...

Testing a wing joiners. :)

New challenge.

Abowe - outer wing part. Below  - inner.

Half wing span - 4,5 meter.

After years of experiments...No more tailless design.

In the last few days I make some test fly for short distance.

On ground station we use YAGI 16 dBi antenna without tracking system, connected to XBee modem with 5 meter cable.

For distance ~2,5 km system work very fine...

 Mamadu take a new fin for better yaw stability.

This project has been started in october 2009  and its purpose is to build a full autonomous short range reconnaissance survey plane.

Currently Mamadu UAV used Paparazzy YAPA v.2 board, CHIMU IMU, Xbee modems for telemetry downlink and VTQ video equipment.
