yogesh commented on Jose Julio's blog post Indoor fun with a tiny ArduCopter quadcopter"One thing that is sort of not clear is how the motors are mounted. Does the bottom-shaft portion of the motor just sit on the hole in the rubber mount in a tight fit? (Picture 12 in the document)"

David Low replied to yogesh's discussion IR sensor calibration"Hi Syariful,
FMA sensor internal circuit
Personally, I haven't tried on the paparazzi sensors (which is based on melexis), but i can assure that the fma one does work well on heli platform :)"
Syariful Syafiq Shamsudin replied to yogesh's discussion IR sensor calibration"Dear David,
Which one is better? FMA thermopile vs Paparazzi sensors. Where can I find info about FMA sensors pinout diagram?
Cheers."
David Low replied to yogesh's discussion IR sensor calibration"Hi Syariful,
yes, thermophile sensor does work on helicopter and is quite well.
there is a Spartan AP2000i heli flight stabilizer, using FMA thermopile sensor (support inertial sensor too)"

Hi all,
We are using the thermopile sensors to estimate attitude of our airplane. The problem is that the paparazzi wiki mentions a nonlinear relationship between the angle and the voltage. Therefore, we can't use it unless we calibrate it experimentally and find the values for different angles and store them in a table. However, that would be cumbersome. It would help greatly if there was a mathematical relation or a lookup table between the voltage and angle, but so far we haven't… Continue
