Radio Settings

Below is an xls download and in it are the settings I use for the current kits, note this is using a DX-8 Gen2, earlier gens or other DX systems may not have the exact same naming, this version of the radio takes a removable Memory card for model storage.  There are only a few settings to adjust.  These all assume you have used the servo subtrim setting to zero out your control surfaces to be perfectly aligned wth the wing for boost, then you add in these settings and verify throws and movement are correct before flying.  There are only a few settings to adjust, aircraft type is Elevon for all models.  Set the servo directions.  I use a timer set up the same for all planes, on Switch D to start on position 2(down).  That way when I activate my glide trim, the timer starts and I can time my glide duration.  This is not required.

I set my flap setting to be active on switch D.  After that you are just setting D/R % and Flap/Elevator boost/glide trim %, that’s it.  Nearly all of my kits with the servos mounted on the bottom of the wing will use nearly identical setup with minor adjustments to D/R settings and Boost/Glide trim settings. Boost trim is what I needed, depending on your build this setting will need to be adjusted.  Glide trim should be pretty close.

This sheet below is for all current and some prior kits.

Note 1: I use the D switch for elevator/flap trim for boost/glide it is the long switch at the top left front and is a three position switch, I use up switch position 0 for boost and down switch 2  postion for glide.

Note 2: I enable my timer to count when the D switch is moved to position 2(down) this is for keeping track of my glide time, when I pitch the model over and flip the elevator flap trim switch down it will start.  It will stop when the switch is moved to the boost position.  I can clear it using the xmitter button.  I turn on voice to activate each minute and when the timer starts, stops and resets, this helps me make sure the switch is in the boost position when I switch it up it will say timer off.

Note 3: These settings are assuming you use the long servo arm(one end trimmed off) on an HS-65HB hitec servo, any other servo may not have the exact same movement amount with these settings.

Note 4: I do not use the servo Travel adjust to set the movement, I leave those at 100% and prefer to use the dual rate elevator/aileron permanently enabled(ie setting is the same for any switch position) and reduce/increase the throws for elevator or aileron using the dual rate %.

Note 5: For the flap elevator trim, flap % is not applicable because you aren’t running flaps, you are just using that for the elevator trim function to allow you to set a boost and glide trim setting.

Note 6: Boost/glide trim settings are dependent on how straight you have built your model and your actual boost and glide CG, they may be slightly different than what is here, you can see that boost/glide trim settings are fairly consistent accross the models, but D/R % may be quite different depending on the size of the control surface and the model. A few needed a minor bit of down trim for boost, most needed nothing.  I like the model to boost slightly away from me, so not quite straight up to allow me to see the model and go up wind.
