"Hi Jose

Our flight controller can do some pretty amazing things. We have various custom maneuvers built in, obstacle avoidance etc..
Would you like to integrate (our FC and speed controllers) with your craft ?"

"Do you have the Aerodynamic coefficients for this airframe ?
What's the stall angle ?"

srinath mallikarjunan commented on Chris Becker's blog post Formation Flying Mesh Network Demo
"Chris

Since you are using point to multipoint, i guess you are setting the leader to broadcast mode, while the others are in unicast. Have i understood it right?
Is the leader set to API mode? That way it can send a frame of data that specifies the…"

"Hey Chris

This work is super cool.
Do you route all communication through the GCS? If not how do you create a Xbee mesh network?
Or do you send and receive messages in a round-robbin fashion on all nodes?"

"This is the cubic spline reference i am following

And code

See how every segment, depends on every other segment. I don't…"

srinath mallikarjunan commented on David Dewey's blog post Flying 3D Spline Curves between Waypoints with ArduCopter 3.0
"Hi David
I am curious as to how you reduce processing overhead in spline computation. For example if there are 5 spline segments, segment-1 depends on segment-2, which depends on 3... and so on.
If you had a mission made entirely of splines wouldn't…"

HiI would like to have 2 counter rotating propellers on a single drive shaft. Similar to a Kamov but of course powered by much smaller (possibly bldc motors)Does anyone have ideas on the mechanical couplings between motor shaft and the propellers to…

"Tommy, It's a great idea.Could you beam back both the video and telemetry using the 3g USB stick?"

"Has anyone tried to transfer a file using a direct modem to modem call? How low is the bandwidth? If the bandwidth is so low, i wonder how 3G video-calls take place."

"Hi Alan
If we just went by the difference in uplink and downlink frequency a 3G video call wouldn't be possible. Clearly the cell-phone tower does some stuff in between.(I guess compresses data and changes the frequency)"

"Let's assume the laptops were in 2 different cities. So you couldn't use a wireless lan/wifi.
A conventional modem would enable point to point data transfer. Can a 3G modem also do this. In which case you should be able to transfer a file from 1…"

"Suppose you have 2 usb 3G modems, connected to 2 laptops. Can you exchange files/video between the 2 laptops without involving the internet.
I know a 3G video call is possible between 2 phones, so i guess it should be possible to stream video from 1…"
