A real life pilot took the flight simulator and put the pedal to the metal
No one's ever flown that hard, seriously. If you ever tried to fly in DCS under bridges or through the Burj al Arab, you know what I mean. The guy has never tryed VR glasses before, has never flown the L-39, has never practiced these maneuvers before and flies in the MotionSim as if it's a walk through the park!

Some say there are no negative or side forces while flying:
Now tell that again

This video perfect shows how strong all forces in real live are (in aerobatic or millitary maneuvers).
It looks to me that negative forces are the worst, but also sway/side forces.

He asticher,

Awesome work you have done there, hope it is working well * Regarding it I have just a couple of questions:

Regarding your quote:

"Some Frame specs:
Pitch Axis shaft drive: d=80mm ; t=10mm; l=1200mm
Roll Axis shaft drive: d=60mm ; t=20mm; l= 300mm
Gears- and Accurators shaft drive: d=25mm (minimum!)
Pitch Axis frame round tube: d=140mm ; t=4mm (minimum!)
Main- and Roll Axis frame L-Profil: 40mm x 40mm x 4mm (better would be 30x30x4mm square profil!)

I use a big double chain for the Pitch axis. It is much easyer to assamble and to get the perfect gear ratio.
Also it is safer, sturdy and your gear box has less stress. The little more weight doesn´t really matter.

For the roll axis i use a direct drive axis through the gearbox. This reduce weight, latency, adds stiffnes, but ratio can´t be changed.

The Pitch axis has a one side bearing (U-Frame). This reduce roomspace but adds much weight and is not easy to build...ok and it looks just better *g."


Do you think it is possible to reinforce your post by adding some detailed pictures where we can figure it out from where you are taking some of the measurements there? You know for those of us that don´t got those skills and want to replicate your project???

Also, at least for the Roll Axis frame, what do you thing about those new Extruded Aluminum profiles, picture example attached?? Do you think they can be strong enough for the duty??

Again, great work there budy.

Take care

No, don't use aluminium, it can break very sudden and without warning (also most plastics).
Wear and tear is a saefty issue - even with steel. But with steel you mostly hear and feel it before something goes really wrong.

About the measurements: This are minimum sizes for proper safety. Everyone with Mechanical engineering knowledge should know what i mean.
Unfortunately, I cannot publish construction plans: The risk of someone accidentally killing themselves through misuse is too high.

where did the details gone ??

Hi Asticher,

First very good job!
Please could you tell me which references of motor you use?

or if you publish a full list of components ?

Awaiting your reply,

regards
