I need suggestions for suppliers & parts :
For all items is important lightweight and compact systems.
1) autopilot and arduino.
2) Aircraft Servos
3) Engines (http://www.rctigermotor.com/) I liked those.
4) Gps & Magnetometer
5) RF / WIFI / 3G / 4G
I divide my systems into two groups,
1) Based on the Ardupilot (setting more traditional blimps)
2) Based on Arducopter
I am currently working on structural parts of the system 1 to be 3d printed in ABS.
When solved I will publish some photos.
