yeah but even EDF have relative aerodynamic lag. With a tractor plane, the wings get extra lift from the propwash a LOT sooner once the throttle is blipped, well before airspeed comes up. An EDF will keep sinking until the airspeed eventually climbs to get airflow over the wings.

But then I am very new to EDFs. I do have some delta wing prop planes though. They love to fly in high alpha, well controlled at low low speed. I wonder if a delta wing EDF plane would be easier to land than a conventional jet layout?

Re: Learning to Fly Jets Easy, Landing them NOT SO!!

Couple of observations:

1) The plane does not fly straight and level, it noses down which means you are out of trim. If it were a real one I'd ask you to check the incidences.

2) It looks tail heavy as well, any plane that porpoises like that shows a symptom of tail heaviness. Are you able to adjust the parameters on that plane to add a bit of nose weight?

3) Practice flying at very low throttle at slightly high alpha, just enough to maintain altitude and do a couple of circuits. Once you get that down pat, slowly bring it down and you'll do a main gear landing.

Plane is just out of trim. Every plane on Pheonix is different. The plane should be able to fly straight and level hands off. I find on phoenix landing any plane you need to let off elevator as soon as the wheels touch the ground.

Paul has the theory to the tee. Get the main gear to touch down first.

Re: Learning to Fly Jets Easy, Landing them NOT SO!!

Looks like it needs some up trim. You are over controlling it. Remember the backwards theme, " Elevator is for speed and throttle is for altitude". If you can find some videos of carrier aircraft landing You will see the aircraft at a constant attitude and by the puffs of smoke in the exhaust trail you can see they are using the throttle for rate of decent. When they reach that magic point just aft of the stern and they chop the throttle and drop to the deck with the nose still high.

The problem i was having, was power responce it was coming on to slow so to speed up or slow down it was to slow causing the jet to nose dive to fast thus nose down and then the nose bounce of death. After i changed the response to 0.75 instead of 0.1 it totally helped..

I also enabled brakes and set them up on my radio so once i'm landed i can toggle the brakes on, with my momentary switch, just like tapping your breaks in your car.

Hard to explain, but i can make a movie now and you will see a total difference. I did trim mine also in the sim and it flys level and proper.
