Channel are not the same as in the radio. Why?

[TDFun66]

Hi,
I'm confused about the channel mapping.

Graupner MZ32 compared to Spirit Software:

Channel 1 (pitch) <-> Channel 6 (pitch)
Channel 6 (gas) <-> Channel 1 (gas)
The same with channel 5 and 7

I'm using a Graupner GR-16 receicer and SUMD.

Is that normal?

It's been a while since I set up a model but do remember having to mess with the channels when I switched to MZ32 SUMD.
I use throttle directly off the RX not through spirit so that caused a bit of a headache also

i guess is just a choice of spirit to adhere to spectrum channel mapping
(TAER) instead of futaba (AETR) or other brand mapping

Just click the channels screen and map your channels to the right ones, no problem here.
