Dein Problem scheint dem folgenden ähnlich zu sein:
Your problem seems to be similar to the one described below:
"I recently bought a Vario Benzin Trainer and a Futaba 9CAP transmitter.
My setup problem concerns CCPM (90 degrees): the control on the
transmitter gives the correct servo-responses in regard to aileron and
elevator (1 and 2) but the reaction of the pitch control gives a reverse
reaction of the swashplate, i.e. increased pitch moves the swashplate
downwards and decreased pitch moves the plate upwards.
The helicopter is built exactly as the drawings and the servos are
correctly oriented. The transmitter is in mode 2 and the swashplate type
setting is "Heli SWH4 type". Elevator 2 is on channel 8.
Does anyone know what I am doing wrong?"
My advice was:
"I don't know the Futaba 9CAP, my Tx is a Futaba FC18, but I should
think they both have similar programming options.
If the cyclic works correctly and pitch is reversed I'd start with
looking at the special gas servo travel option. There ought to be a menu
item which lets you select one of three effects of the trim slider:
"(Unilateral trim) Inactive" - which means that trim works likewise in
both end positions of the stick, "Active" - which means that trim works
only in one end position, and "Reverse" - by which the end position in
which trim is ineffective is swapped.
In my Tx this option, in combination with a CCPM mixing programm,
defines if collective is operated by pushing or by pulling the stick!
This might solve your problem. If necessary, switch the gas servo to
reverse."
