  • What is the affect of motor to motor diameter ?
  • What is the affect of maximum propellers length ?
  • How to measure quadcopter speed
  • How to measure air density ?how it does affect the flight time ?
  • Ground speed vs quadcopter speed ?
  • how to measure quad altitude ?
  • can i get see , altitude on screen using mini OSD ?
  • i am using mini OSD, any programming for it is needed ?or it can be used off shelf ?
  • is it a must to reprogram the ESCs i.e. flush BLHeli firmware ?
