1 – Overview
Thi example how the etup of a Heron glider, with flight pha e a follow
Speed – Reflex flap and aileron
Normal – Flap mixed with aileron
Thermal – Thermal flap and aileron (full pan camber)
Landing – Crow braking on tick with elevator compen ation
Profi – Example – Heron Glider

2 – Control a ignment , flight pha e , mixer definition ,
ervo a ignment
Spoiler a igned to tick and throttle to lider G, mode 2 o tick i on left. Note no
control a igned to flap a thi i et by flight pha e in control menu
Profi – Example – Heron Glider
Flight pha e 1-3 a igned to 3 po ition witch 2 on lefthand ide and flight pha e 4
to witch 1 on lefthand ide, flight pha e group not u ed.
Throttle-cut and timer allocated to witch 1 on right hand ide o that timer tart
when throttle i active

2 – Control a ignment , flight pha e , mixer definition ,
ervo a ignment
Flight pha e named a SPEED1, NORMAL , THERMAL 1 and LANDING 1 (none after
late t update 3.56 my Profi only announce LANDING on the LANDING1 flight
pha e, I think thi i a bug in the ound file in the Engli h language ver ion), o
with witch 2 up, SPEED1 etting are enable and down THERMAL1, when witch 1
i down LANDING etting are enabled
Profi – Example – Heron Glider
Servo a ignment u ed, note if FLAP geometry on both flap i ignificantly out and
can’t be matched with a 3 point curve then a 5 or 9 point calibration curve could be
u ed

2 – Control a ignment , flight pha e , mixer definition ,
ervo a ignment
Mixer definition are et up in the define mixer menu, which i in the etting menu,
note thi i the li t of available mixer template in the Glider+ model template
which can cater for a glider wing with 8 eparate control urface (4 per ide), only
FLAPS-1+, AILERON+ and ELEVATOR+ are u ed.
Profi – Example – Heron Glider
AILERONS + menu, thi i the tandard AILERONS + menu, note Aileron, Flap and
Elevator (– trim) input are hown a active, but poiler input (for crow braking) i
active on Fp4. Note you cannot elect Fp4 a the witch by toggling the witch but
by crolling though the witche u ing the programming wheel (or the -/+ button
if you prefer)

2 – Control a ignment , flight pha e , mixer definition ,
ervo a ignment
FLAPS-1+ definition mixer u e tandard FLAPS-1+ mixer template, note Flap and
Elevator-T alway active, Spoiler tick in Fp4 and Aileron tick in Fp2, the a teri k
how current active flight pha e
Profi – Example – Heron Glider
ELEVATOR + menu, thi i the tandard ELEVATOR + menu, note Elevator, Rudder,
Flap and Throttle - Trim input are alway active, but poiler input (for crow
braking) i active on Fp4 only

3- Servo Calibration
In order to calibrate the ervo , it i important that there are no unwanted mixer
effect affecting the et up, the input need to be a clean +/- 100%, here you can
ee that the flap input in the Servo connected to the FLAPS-1+ mixer ha been et
to 100% in each direction with no other input .
Profi – Example – Heron Glider
A we have no pecific flap control on thi model but in tead are u ing fixed value
defined for each flight pha e we need to enter the control menu and et up -
100%,0% and -100% on the thermal, normal and peed flight pha e , we can then
calibrate the ervo again t the e 3 point . An alternative would be to temporarily
a ign a lider for flap control and u e that during ervo calibration and then later
either remove it from the control a ignment or by etting a flap control fixed
value for each flight pha e the control will be overridden by the fixed value (i.e.
control will only work if the fixed value i et to OFF)
For the mixer to work correctly, it i important that the ervo are correctly
calibrated, i.e. paired ervo re pond identically to a control input, if not any mixer
adju tment will re ult in mi -matched movement . If your ervo and linkage
in tallation are exactly the ame then the ervo calibration curve will identical
(and hat off to you!)

3- Servo Calibration
Profi – Example – Heron Glider
Then on one of the flap channel (no 6 above), et up a traight line curve which
determine the maximum movement of the e urface under all input , do not
worry about etting actual thermal, peed, poiler movement at thi tage the e
will be determined in the mixer control etting , the purpo e of thi tep i to
determine the mechanical limit and then adju t the econd FLAPS-1+ ervo (7) o
it’ direction and movement matche that of the other at all three point (by
changing the flight pha e ). Al o do not u e the ervo curve to et the flap neutral
po ition, ju t make ure both flap are deployed the ame amount when Fp2,
Normal, i elected, the po ition will be adju ted in the mixer, via the poiler off et
etting.
HINT – if you tart off with a +100 to -100 ervo travel you may end up with ome
ervo binding, o I u ually tune down the movement to ay +/- 25% before
operating the control input, and then increa e them accordingly.
Calibrate the AILERONS+ channel in a imilar way with ju t aileron input ( et 100%)
in the mixer, do not et aileron differential at thi point a thi i et in the
differential mixer and by electing the poiler option in differential, differential i
removed a poiler control rai e the aileron to give more down going aileron and
hence more control authority.
