I need to sort out the project a bit. I did some changes to Basic model during this winter and now I have to split project into 2 parts.

Quad has got currently F-450 frame and it connected to Pixhawk and Raspberry Pi03. I decided not to expand this copter too much and focus on basic target for this construction. I will try to add any handle mechanism (maybe small servo mechanism) but nothing more. This drone will stay as it was planned at the beginning – it should fly, take something on-board and back to starting location. Everyhing should be LTE navigated and that will be fine for me. In future posts I will be naming this configuration/drone as ART3. I need to do this because RPi0w is too weak to handle other, additional functions not available on-boarded now.

Reptile`s based drone with Raspberry PI3 on-board has codename ART4. I will be using this drone for other new features. Drone plates are bigger and RPI3 is stronger than PI0w so I can install onboards other items like gimbal or any additional sensors. ART4 drone will be powered also by E305 propulsion system and I think this is good solution for me because I can use some parts shared between those drones to reduce daily costs of maintenance (e.g. common battery, propellers, modem etc). In next couple of weeks I will put together all ART4 parts I hope.

Below small photo that shows dimensions differences between both drones (ART3 F450-> on the left, ART4 Reptile->right).
