Octocopter - Hubsan X4 H107L Mod

This is my first octocopter prototype, a modification of the famous Hubsan X4 H107L quadcopter.

The original Hubsan 240mAh battery lasts not very long. Adding a second one parallel to the first one will probably extend flight times. With a 1000mAh battery (https://www.conrad.at/de/modellbau-akkupack-lipo-37-v-1000-mah-10-c-conrad-energy-bec-209254.html) I reached up to 12 minutes! Additionally, I think most parts can be designed much thinner to reduce weight and extend flight time.
