Default RE: Throws for 3D Edge 540 .46

They should be set to minimum and the radio set for low rates if you are using dual rates. Set the elevator and ailerons for about 30% exponential, and be very careful for the first few orbits. Once you are happy with the performance (generally speaking.. if you can trim it out to fly straight and level at one throttle setting (most likely slightly above mid throttle), HANDS OFF (meaning just remove your fingers from the sticks and see if it flys straight and level), then you are ready to go forward.

Do some slow orbits, one end of the flying field to the other, do left AND right turns, then slowly push the throttle to full and pull to vertical, and go straight up. Do a hammerhead turn (Stall turn.. at epogy, min throttle and at the same time left or right rudder and get it to pivot to straight down). Then about two mistakes high, go level and move to mid throttle again. Make sure you are "two mistakes high" meaning high enough to recover from any problems.. much higher than you would normally fly, in other words, then go to max right or left aileron. See how the roll rate is. If it meets your needs, wants, and desires, then you are all set. If not, well, if it's to severe, then carefully land and remove some of the throw. If it is less than you want, but rolls ok, then try high rates.

Do the same thing for a loop. Go to straight and level flight, into the wind, then push the throttle to full and slowly pull the elevator to a comfortable loop.

All this will help you see how your throws are set and if your rates are adequate. I see that you have a computer radio.. exponential, dual rates, and so on.. so you can adjust all of this but do it on the ground, not when the aircraft is in the air.

Bottom line, set the rates to minimum. Most manuals will give you that. If not, well, try going to Tower Hobbies web site, for instance, and look at the manual for another (different) Edge 540 and see if they give throws. If they do, well, use them to start off with. But, if you re not sure, well, set them up for what you think you can fly with (don't set them for 1 inch throws, for instance), but set them and then put in your dual rates, set the rates to low, and dial in exponential, and carefully fly. You flew a Stick, so you know what you are comfortable with. Expo will ease the transition of the control surfaces so you can gently maneuver the plane while getting the feel for the throws. Just don't play the "video game syndrome" and go from zero input to full stick deflection like I see some people doing.. be gentle and use minimum stick movements at first, only enough to control the airplane. You can then play with the adjustments in subsequent flights.

Remember that for your maiden, you want to make sure it flys, and that you have good control. Not 3D control, but straight and level with smooth turns. Then slowly, from flight to flight, go from there to however radical you want the thing to be in small increments, meaning, fly it, see how it is, land it, make your changes, fly again. Repeat this several times. You will do two things. You will get comfortable with the plane and how it flys, and you will begin to get the throws where you want them to be.

Don't go for max throws to start off with, in other words. Start out mild and sedate and go from there.

As I said, you can get information from other manufacturers of the Edge 540 and read their on-line manuals to see how much throw other Edge 540's have. Just remember that the settings are for their designs so be careful, and set them mild and sedate to start off with.

Good luck. Let us know how you make out.
