1) If you are hand launching, do not throw at a steep angle, keep it to about 10 degrees.
2) EDf's normally get 3-4 minutes of flight, so keep it timed and on your
maiden flight, I would shoot for just a
2 min flight.
Why? If pilot screws up landing and needs a "go around", and you go up to full throttle and make then make another approach, you better make sure you have still have enough battery left, or you will suffer the consequences.
3) If intake of EDF's is near ground when landing, always check to see if pebbles, small rocks, even wet clump grass, can destroy the fan blades if it is sucked in. I always buy a couple of sets of spare blades since EDFs models tend to disappear after a year or so on market. Even caught a servo wire not taped down.
4) A way to
reduce spooling time is to go to the tx radio and look at the throttle curve.
What I did is add an additional point on the curve.
I bumped up the new 2nd point to about 29 % (before it was a straight line) so now this is at a
higher spooling for a small amount of throttle.
Concept is, when landing, you always have some power on with EDF's. What I did, is match the spooling up speed to my landing approach speed(memorize the spot on throttle) so I'm powered up and ready which produces a fixed landing speed just like a pro. Yet still drops of rapidly to shut off the EDF when you land.
Sound good.
