"Just FYI aerodynamic torque compensation has been around for a very long time (google "stator vanes").It is worth noting further that any static system can only compensate for torque at a single mass airflow rate, and that at all other…"

"Very interesting, theoretically I term should never affect the transient performance of a system, especially not make it unstable. There are exceptions to this, you may find that introducing the zeros from your I term in your transfer function is…"

The Sun replied to Chris's discussion Why aren't there more single rotor drones out there?
"The idea that a single or coax copter does not tilt to move laterally is incorrect. Coax and single copters both use the exact same method to translate that quad or other multicopters do, the vanes create a moment about the center of gravity of the…"

The Sun replied to Zach Smitty's discussion Is T-Motor the best?
"Of course, though most suppliers also specify a cell count for your maximum amperage which will give you the same thing. "

The Sun replied to Zach Smitty's discussion Is T-Motor the best?
"T motor is good, but often rate motor limits in watts which is generally the most useless form of motor limit data. KDE does tend to not only provide better information on their motors but also has most of their motor limitations clearly in amps…"

The Sun replied to Chris's discussion Why aren't there more single rotor drones out there?
"I will have to disagree with some points on single copters here. As someone who has built a great number of single and coax copters with vane stabilization I can say that they are in fact perfectly stable in even gusty conditions. The real issue is…"

"@itcanonlybejared 50 mile ranges is nearly impossible to achieve without either relays or satellite links, are you achieving this number using free space loss calculations?"

The Sun commented on Mauricio's blog post Why vertical takeoff when you have the Aeromapper Talon?
"You are probably significantly fatiguing that airframe doing landings like that. Also interested in how the parachute landing system could have a 100% success rate, what about wind gusts and such? I imagine its not particularly controllable when…"

"You are right, I did a little research and it seems like that's how it works. I will try this this week, your right we can use the derivatives to offset the accelerometers input if we need too, hopefully that is not too much of an issue though…"

Forrest Frantz replied to The Sun's discussion Mounting a flight controller not on the CG in the group ArduCopter User Group
"so many unknows. what i thought happens is that there are three gyros (x, y, & z) in the IMU that measure angle. [there are also three accelerometers]  Mathematically, one can then put the gyro angles against the clock and you can…"

The Sun replied to The Sun's discussion Mounting a flight controller not on the CG in the group ArduCopter User Group
"As far as I know the accelerometers also sense the angular acceleration don't they? The proboblem with biasing the accelerometers either way is that it is not particularly simple, and would probobly be somewhat difficult to implimemt The…"

"Ok, that's good to know you have had it off centre with out effect. the hoop I have in mind is going to be a couple meters in diameter, but I'll see if I can mount an Fc out by the motors on one of my smaller quads."

Building profesional; high strength, aesthetically pleasing, landing gear in under 48 hours

Posted on April 1, 2013 at 2:30pm 7 Comments

Just finished trimming and sanding my newly fabricated landing gear.

As best as I can tell these things are incredibly strong, and as they are made of fiberglass quite shock resistant and incredibly forgiving to sheering force. These are for my 10lb aluminum H style A/V Quad that is almost done. The…
