Elevator 12mm high rate 8mm low rate
Rudder 12 mm
Ailerons 12-14mm high rate 10 mm low rate
These should give you a pretty good starting point.

Can you take a flashlight and look down the fuse with the radio on and see if the rudder cable is flexing? If it's not glued in back there, you can just stuff a piece of styrofoam down the fuse with a small wooden dowel to hold it in place. (There's a couple other ways to stabilize that cable too)

Thanks Tahoe,

Unfortunately I have to start over on the rudder elevator installation.

I thought I could reuse the tray but it was to short to install servos in tandem.

So when I offset servos everything was great till I tried to put the nose cone on

So I ripped out the old tray and I'm starting from scratch.

Should have from the beginning.

One thing I remember is that you are suppose to program the crow after the basics before the rest of the stuff or else it will change other settings. Don't remember what it will change or by how much, but that it did.

Here is my setup for a F3F I had. It should get you going. Values are positive unless noted otherwise. Your values may need to be different and you may like less expo.
Basically it's;
name, glider, modulation, trim setup for ail ele rud all 4, v-tail inh, dual flap act, flap ch input flap sw+P6,
MAIN MENU; (other than ail to flap & flap to ail - values for you may need to be different)
servo rev, sub trim,
travel adj; SPOI +81%, - 100%; AIL 1 L 100%, R 127%; ELEV U/D 100%; RUDD U/D 100%; Ail 2 L 132%, R 150%; FLAP U 6%, D 11%, AUX 2 100%, AUX 3 100%
D/R & expo; AILE pos 0, D/R 95%, expo 70%, pos 1, D/R 51%, expo 44%
ELEV pos 0 D/R 115%, expo 65%, pos 1 D/R 60%, expo 30
RUDD pos 0 D/R 125%, expo 60%, pos 1 D/R 100%, expo 40
ail to flap 100%, flap to ail 100%, differ 35%,
butterfly; (position
of the
gear sw)
spoi > ele: 0: + 19%
1: +4% (this was to get rid of the change by flipping the sw, you may or may not need this)
spoi > aile 0: +25%
1: 0%
spoi > flap 0: -72%
spoi offet: -170%
PROG MIX 2; spoi > spoi
with the spoi stick down; IN says 5 & OUT says 0
with the spoi stick 1/2 way up; IN says 50 & OUT says 1
with the spoi stick all the way up; both say 100%
PROG MIX 3 (not sure if this is needed or not but its there. I think it's to disable crow with the gear sw so i just use during landing)
spoi > spoi
Rate: -125%
Offset 169
ele > flap mix: Rate: D +15%, U +20%, sw. MIX
flap > ele mix: Rate: U+ 22%, D 0%, sw. ON, offset flap 0
ali > rudd mix: Rate: +31%, sw. MIX
D/FLAP T: pots 5 through 7 INH

Let me know if need any more help programming the 8103 when it comes time.

Thanks Bob,

I appreciate you guys taking the time to assist me with the radio/glider setup.

I'm brainstorming the servo installation. Considering bolting the two servos together with a locking 4-40 set up.

Yes, with the servo tab overlap, the aft servo will be about a 1/16" higher. Doesn't matter both servos will sit low enough.

Then a couple of cross rails on each end.

That's the beauty of this hobby, no rules, at least for now.

Could also do something like this. a plywood tray will help strengthen the fuse. The two cross rails could pop loose pretty easy on just a slightly rough landing.
