  1. maybe I should find courage to follow your advice, Spitfire76, of many posts ago and build a drone adapted to the specific needs,; stable flight, good payload (might as well look for at least a kilo), maybe gps and visual positioning for hovering, 10 minute flight time (i have to refill the spray) extendable if i use carrying capacity for battery rather than spray contraption. In the meantime its time i learnt to fly so i bought a x8hw to make my first mistakes with.
  2. It also has an 8s 5A-H lipo! But... I found an excellent German Co who have the DE concession. Seems the drone has teething troubles and isn't available to the public yet. I also found so many inconsistencies in claimed "payload" that the figures seem to be meaningless. batteries, gimbal & cameras are sometimes included sometimes excluded but often not clear. payload is confused with max takeoff weight. No-one seems to have analysed available drones to give precise comparisons (true payload, motor thrust etc. I presume the 35 and 08 must mean something tho I haven(t found what precisely except that heavy drones have "35" and more something and lighter ones less than "35". I did learn that a drone should hover at 50% max thrust or it can't be controlled. As you already mentioned. So surely it ought to be possible to get a reasonably precise correlation between thrust and motor reference and/ or propeller dia in inches? Maybe with that I could get a better idea of acceptable takeoff weights and hence payload?
  3. That's several good points, especially as I would like the drone to remain still while I spray. I found a site that claims to give the permissable extra loads. For P3 they estimate 300 which is not enough. Frustrating but I m sure I'll find the right drone in the end. They mention another drone " It can carry 2,300 grams or 5.07 pounds in addition to the weight of its built-in components" thesite is jyu spiderX is the drone, availablein Germanyfor a little over $400 in fpv version. i can't find any reviews, can you form an opinion on basis of the spec? . building one is a good idea but I would have to follow a long and painful learning curve.
  4. Thankyou Spitfire76, you are an inspiration. Wow the price of the 3DR Solo in the US is unbelievable at less than $300!!! That would be perfect but they won't ship to Europe. I just checked and it's over $1000 in Europe!! Perhaps it will come down. For the P3 I found this video that seems to be by a serious company in the Netherlands. they install thermal immaging equipment on P3s. they show the curent drawn to maintain different total weight of the P3 I summarise their results in attachment. a 500g extra load increased power required by 70% and reduces flytime from 25 to 15 minutes. that could be OK for my purposes.
  5. The tallest trees on my plot are about 15m. I'm on the side of a mountain so the slope averages 25° . Trees are mostly Spaced so i could pilot from uphill to get a better angle of view. I agree it's not easy, I'll experiment with higher pressure vessels to get a longer jet so the drone could be 2 m from the tree. looking at cameras and 3 axis gimbals, the weight seems to be about 400g. I don't need high definition or 3 axis stabilisation to aim at a 20cm dia target so I thought I could use a 1 vertical axis gimbal and small camera weighing < 100g. equally I don't need 30 minutes flight time (at least not to prove viability of the project) so I could save 100g on the battery. I note the drones (eg phantom 3) perform fully equipped at 6000m altitude whereas I fly at 600 - 700 m. shouldn't this enable me to add a 400g spray unit? In which case could I look at the much cheaper leisure drones rather than high performance professional machines?
  6. That makes much more sense than the info I found, thanks for the research! And it is what I've been looking for as far as payload is concerned. Should I then conclude that I have to spend about $5000 on a suitable drone? It seems to have a lot of qualities I don't have to have.
  7. Thank you, Spitfire 76, the matrice 100 looks good and can carry a second battery that weighs 5kg so with just one battery it must be able to lift a 5kg payload, 10 x the load I need to lift. But at more than $5000 equipped that's also a bit more than I hoped to spend on a crazy project. My problem seems to be that payloads are rarely specified, except on the keyshare glint ($450) which claims 1 kg payload but for which I can't find positive reviews.
  8. Thanks, Timmy, but before I start dreaming of glory, I need some advice on the sort of drone that could manage this task.
  9. Thanks Ed, the legal side is of course most important. For the next two years the legislation is reasonable and pragmatic. Under 25kg and for personal (not professional) use there's no requirements beyond a set of common sense rules to follow. a good site explaining this is or for the rules in English I have the strong support of the mayor, who is law & order on the commune so don't expect any difficulties from that quarter. I too thought the DJI reply was from their legal dep't rather than from their test pilots.
  10. Hi I have never seen a drone fly, so I need advice. Reading this website, I thought someone may be able to help. In my area of southern France, the Diois, there are two nuisances, chenille processionaire (processionary Caterpillar, Thaumetopoea pityocampa) and soon to come the frelon asiatique (Asian Hornet, Vespa velutina nigrithorax). One causes debilitating allergies and the other will kill my bees. Both build nests at the top of high trees. My idea is to adapt a drone to carry a pressurised 500 or even 250ml can of specialised insecticide and using fpv, a gimbal mounted camera could direct a lightweight tube to accurately spray the nest without damaging the environment. So I need a drone that will hover within 1m of a tree, that a novice can fly with a 400 to 600g payload in addition to battery, camera and gimbal and that won't cost too much. To illustrate the task I post a couple of photos of the targets. They are high in the pine trees and at the extremities of branches so the drone would have to hover at 1 metre from the tree. I envisage a servo to trigger chemical flow. My idea would be to use a converted aerosol with a flexible tube then a 400mm al2 tube attached to the gimbal. The gimbal would only have to move on a vertical axis so that might leave a channel open to activate the servo. The chemical is water based and used by the government to spray vast areas away from habitation. It won't harm drone or (much) the pilot. I want to deliver small quantities targeting the nests. To avoid downdraft from the propellers, , I would try a long, lightweight tube to spray outside the main turbulence and alternatively, spraying vertically down. I'm confident I can build the spray delivery device after some experiments. We discussed this problem in the village. Almost every pine tree is infested with at least one n'est. other solutions are more radical; shoot the nests down (there are so many someone would get killed), cut down all pine trees (a shame in mountainous terrain). My real problem is ignorance of drones so any advice much appreciated. A little research suggested DJI might have something. So I asked DJI and got this discouraging reply "we do not recommend flying "all-in-one" aircraft with any payload other than the included DJI gimbal and camera. Because extra loading may affect the aircraft’s endurance ability and orthocenter which lead to a bad flying performance" I also found a drone called Keyshare Glint-pro+ with good specs including a 1kg payload, at less than €500 including battery, gimbal & camera. But I only found one user review and it suggested the Glint-pro was unreliable to the extent of being unusable. I would be most grateful for any advice on the project concept, knowledge of the Glint pro and recommendations for other drones that might be suitable for my unusual payload.
