This is my KickStarter, https://www.kickstarter.com/projects...obotic-systems

Im trying to reduce collision probability for indoor and outdoor flight. Previous lidars were too heavy and cost to much. Ive engineered this version to be more compatible with embedded systems.

this is my reciept number i guess, ill be looking at other action to take against the FAA as well.

the interpretation was just so poorly written and non-nonsensical, probly making things less safe, and more convoluted.

To Whom It May Concern,

The FAA is in danger of losing credibility and effectiveness, by over regulation, denying FPV capability and a general hostile attitude towards a large section of the American flying population that only grows. Worse, ( and I do not advocate for this ) many young people may choose to fly out of resentfulness and spitefulness, at which time the culture of disrespect for the FAA will become popularized, making your own task impossible.

So far the FAA has been more the problem, than the solution in this fast growing field of aviation. This poorly conceived interpretation is the proof.

I will remind the FAA that they are bound by the US Constitution and to serve the American people, not themselves.

Above all else we must establish simple and well working "rules-of-the-road" for the sky, known to all, and resistant to human factor errors. I greatly fear this task of safety may be beyond your ability.

MultiWii 2.3, PID tuning w/bluetooth module.

im trying to get my MultiiWii pro board using the bluetooth module and android app.

I'm trying to get this to work, but it's all a blur at the moment... the app is really cool looking from my galaxy tablet, and it should be less tedious then using a laptop and constant plug and unpluging of a micro USB cord.



Ive gotten real time in-flight data from excess "P" value oscillation, which allows better tuning of the whole PID process. ill post these details in a few days. i use the Bluetooth module and the tablet app which allows data returned from the acc, gyro and other onboard features. (in the picture, you can see i plugged it in wrong.)

I keep forgetting how I tune my PIDs for each new tricopter I build. So, I'm putting my specifics here.

This is a work in progress so please bear with me for a few days.

File Edits ( Arduino ):
to come shortly.

PID Tuning Sequence:
(For MW ver 2.3 - May, 2014 )

First, deactivate Angle and Horizon mode, (to enter Acro mode).
Second, tune "P", then "D" , then "I", then maybe go back and re-up "P" again.
Next, tune with "Horizon" mode activated.
finnally, enable "Level" mode and adjust those PIDs.

NOTE: The roll and pitch are linked, so choose P values for both, then both D values then both I's. then do yaw by itself.

uniform roughness for boundary layer control. CF is 5.7 oz/sq/yd AS4.
about 0.010 thick, but the weave is the roughness. so it is uniformly created by the 2x2 twill. which has a +.005 and a -.005 total deviation from mean/average... these long airfoil supports Cyberdactyl, were my attempt to keep the TCE from being garbage

so it would appear you and i are attempting to replicate the form and function (though differently in means) of the vortex generators, like on the tail planes of the B-52...
