"Good luck to you too!
I've read many times on these forums that solar panels cause more weight/drag and actually don't help the flight time because they don't create enough power to make it worth it. The cons outweigh the…"
"Hi Dronez, regarding your questions...
my answers for some of them would be:
2) Electric motors are part of the solution.
Airframe mandatory things...:
-Charging the batteries. Solar panel on top of main wing?
"True. If your only looking looking for a 6-7 hour flght (still very long) you could probably loose some of the gas tank in order to free up space for cameras gimbles and other bells and whistles. I guess the TAM proves that extremely long sustained…"
"Well, obviously the TAM could handle the wind.
I assume a good comparison would be regular RC model aircraft. They can fly in the wind, but is not ideal. Obviously, wind will knock around the plane, but the PID should be able to…"
"The dynaflite has the same wing loading as a thermal airplane before adding any of our autopilot electronics/extra gas tank. It is only three channels - throttle, rudder, elevator. You could modify it with ailerons. I guess you only really need one…"
"If you are looking for endurance flight of an automated model aircraft, you absolutely should check out Maynard Hill's TAM 5. The TAM 5 crossed the Atlantic ocean in over 38 hours with about a gallon of fuel. They used a OS .61 retrofitted…"
"I realize I could easily exceed 1 thousand... I can do that. Maybe even a couple thousand... but not 10K
I'd love to find a buy-able kit airframe that could sustain UAV electronics and stay in the air for 2 or 3 hours.
And that was a…"
"I can see exceeding 1K in onboard electronics easily when you consider APM, Rx, servos, FPV, batteries, motor/engine... I am pretty accustom to larger aircraft having dual Rx as well as dual power supplies. This sort of redundancy…"
"Really? Why in the world would it cost that much??
But I was just wondering if 6-7 hours is possible. I'm not dead set on needing that long... just wondering. What off the shelf model were you referring to…"
