Note:
Contrary to the separately set aileron trimming, see
below, the trimming is transferred proportionally to the
set mixer value with the mixer “EL  FL”.
The following settings are model-specific and
may not be adopted without checking that they
are correct!
In the top line of this “Multi-flap menu”, analogous to
“normal” four, six or eight flap wings, the effect of the
aileron stick will be set to aileron (2), camber flap and,
if applicable to FL2. One line below, in the line “Ail-tr.”
line, will set the influence of aileron trimming on ailer-
ons and camber changing flaps.
The setting of a differentiation is rather tricker due to
the model type and should only take place based on
a feel for the flight behavior of the model.
The line “

” should then be set to the standard
default of +100 % in the “FLAP” (or “FL2”) column – as
shown – to 0 %, just to be safe:

With delta/flying wing constructions with more than
two flaps, more moments can be compensated for.
For example, the “lifting” moment caused by the
raising of the ailerons (= elevator effect) can be com-
pensated with camber changing flaps lowered corre-
spondingly wide ( = hydroplane effect).
If you decide in favor of this model type and have
assigned the receiver outputs in accordance with the
connection plan shown above, the aileron function of
the two (exterior) aileron servos will function correctly
immediately, but not the elevator function of the two
aileron servos and, if applicable, the (interior) camber
changing flaps.
This is only then achieved for “2/4 AIL 1/2/4 FL”
when, in the “Multi-flaps menu” of the …

… menu, is set appropriately in the “HR  WK” line
to “Aileron, camber flaps” or, if applicable, “Camber
flap 2”:

Even though all inputs are set to “free” by default
in the »Control adjust« menu, should a control be
assigned sometime by mistake … then it will at least
have no effect.
The last line, “EL  FL”, was explained at the begin-
ning of this section.
In principle, the author of this manual had pro-
grammed a delta model years ago operated with the
mc-20 of that time and a crow system as landing
assistance … entirely without tilting moments through
correspondingly attuned wing mixers “Brake  Ai-
leron” and “Brake  Camber flap”, whereby “Aileron”
refers to the exterior rudder pair and “Camber flap”
refers to the interior rudder pair.
To achieve this now with todays
mc-16 Hott or
mc-20 HoTT also, switch to “Brake settings” in
the …

… menu, and enter the values for the ailerons to be
raised and the “flaps” to be lowered in the “Crow” line
so that the occurring moments compensate one an-
other and the altitude of the model remains stable. In
the process, however, you should leave the flaps with
enough “play” for the elevator function!!! Therefore, do
