Hi guys my first post here.Me and a friend of mine is working on designing a low cost mid range drone for agricultural and law enforment use here in Jamaica.The range we are hoping to achieve is 100km radius with a max altitude of 12,000 feet and a cruise altitude of about 9000 feet. Maximum speed should be about 100kph with a cruise speed of about 70kph and a stall speed of 25kph. The craft should be able to carry up to 8 pounds of payload including a gimbal btc 88r camera and 10x 50mm smoke grenades(for the marking of objectives for ground units during search and rescue). The system should also be able to transmit video signal along its entire flight radius to a semi mobile baseThe specs we came up for this is the following:23 ft wingspan9ft fuselage length25 pounds empty weight, 42 pounds fullAn 8 hp engine running in at about 5 pounds in weightI have a mockup drawing(done in paint and working to implement in cad) will post that at a later date.We are planning to build a 1/3 scale model for testing starting July. The test model will have everything except the gimbal camera and should have a range radius of about 10km. We are planning to use a version of arduino for this but will use a more sophisticated autopilot for the full design.What do you guys think?
