"The clockwise motors,1,3,6 are less power than the counterclockwise,2,4,5 motors. It is compensating for an inherent yaw in the airframe. I am assuming you have clamp type motor mounts and tube arms. Check that all the motors are on the same plane,…"
"From your picture I can see that it is installed correctly with the yellow arms being the front. Also the fact that is flying means it is the correct orientation, otherwise it would flip over. I think what you need to do is reverse the pitch…"
"Probably real good for a efficient long endurance fixed wing, but not so much for a copter. While the energy density doubles, the maximum C rating is one fifth of the best copter batteries, only 2C. You would still be pushing C limits, but my 650…"
"I had this happen to my copter after a benign modification. I have very well balanced props and they are checked on a Dubro balancer. I changed motor mount because I thought they would be more secure, but they added 20 g and extended the arm length.…"
I have just looked at some of your latest logs. Same critical problem exists, bad voltage to the pixhawk, excessive battery voltage drop from idle to flight.
power from my copter
"I doubt any one will volunteer to help you until you explain what you mean by "armed drones". I think we might have a language issue as that sounds to me like you were using a weaponized drone for photogammetry. If you don't have an…"
"Wow, that will be a monster machine. Are you talking about a 200 lb. payload or gross vehicle weight? If you are talking 200 lb. payload it will be under powered. I figure your motors ,esc's, and 12 s battery for each motor will weigh ~ 100…"
Hey Greg ! It hit me while I was sleeping tonight and woke me up ! Getting baby scale is an Excellent idea! not just to weigh the plane but if I get one that shows ounces and fraction of ounces I can weigh each item and figure it's moment before I put it in the plane and help figure the best spot for it from the COG + or - and keep the trimming ballast to a minimum. the rest of the plane will be foam I have been looking at power plants and might do Something Novel ? I am aiming for a take off weight of 4 1/2 to 5 pounds if I get a power plant out of something 7 to 10 pounds it should be lots Thanks! Have a Great Day!
I read your posts that you have made a camera gimbal stabilizer. I work on Arduplane source code, with the APM-1 board, attaching 2 servo to work out solution for 2-axis stabilizer. It will be helpful if you could share your source so that I can have a look at it to get a better idea !
