The combination of these, using one battery at a time (for better at-the-field testing times), should allow flight times of approximately half an hour. For propeller choice, I have gone for a scale-ish 3-bladed unit from Master Airscrew; 12 x 6 inch.<\/p>\n Running cost at this point, is now c. \u00a3350, including the original Arduino electronics and sensor modules. Significantly less, it’s worth noting, than any comparable equipment you could buy… Let’s say a comfortable factor of 10.
