As written in part one we want to make the system as light as possible. In order to do that we also had to build the propulsion unit a small volume. This means that all the components are moved very close to each other to save weight and space.

For the battery we have used high density Li-ion round battery and designed a carbon tube where they have a perfect fit and with the electronic unit located behind the batteries.

The carbon tube is also the mount for the motor and to get a high level of performance from the propulsion unit we had to customize the engine, so we gave the rotators of the engine a spinner shape.

    I am very interested in this project. I live in a town called Northeast in Pennsylvania. It is grape and wine country. I am development agricultural automation systems particularly for use in viticulture (grapes). I currently am involved in project with Cornell University agricultural extension to calculate vineyard yield using NDVI. We currently tow the sensors through the vineyard, then run some statistical calculations. We can estimate yield to within 3% of the actual produced crop. I am creating web delivered Mapping to overlay actual digital maps with our NDVI measurements. I am very interested in this design possibly with the idea of converting from towed sensors to airborne sensors. And such that a grower would have reason and ability to scan his vineyard regularly. Currently we merely "sense" the NVDI data once a season, some predefined number of days after the vines "wake up" from the winter sleep and chutes (the first green ) emerge from the vines. I have researched quite a bit on drones. One of my key issues is the amount of time a drone can stay in the air vs the cost of the drone. It seemed to me that a very lightweight almost fabric covered drone much on the lines of an ultra light aircraft would be superior. By reducing the weight as much as possible with lighter, stronger materials, then less "lift" is wasted. I wish to speak to you about your drone if possible. I find the design intriguing.
