  1. thanks a lot for your contributions am not really a maths person but i totally get it so guy my ideal is to make an aircraft like a car would surly be bigger because of battery space and other motors or something of sort where by you drive home and park then and while driving during the day you have the body built with solar frames might not do much but can at least add a few minuets to the flight time what i really am not sure if this make much sense but i sure do know it not nonsense
  2. how much battery power do we need to drive a plane for 3 hours ? we can fly if we have an air lock oxygen mask and a cooling system for the battery and the body space what do you think ??? something like a flying car or so maybe then we can fly at different speed altitude in the sky what do you think guys it sounds impossible but i do know that nothing is impossible !!!
  3. I know you are a pro when it comes to axpert inverter repair I have a 5kva axpert inverter that when you power the system with battery and turn it on it starts and supplies under voltage and goes of immediately and come back on it does this continually without going off until you disconnect the battery

      "it starts and supplies under voltage"

      What you you mean by "under voltage"?

      Are you saying that the AC output produces less than 230 VAC?

      Or doesn't it even get that far? (It sounds that way).

      How long is the display on, after the "lamp test" that turns on all LCD segments?

      Do the various power supplies (+12V, -12V, +5V) come on with appropriate voltages?

      If you remove the control board, do the power supplies come up and stay up?

  4. My axpert inverter comes on and display 20 volts on output and reboot it self continually
