Hi.
It seems that in my new Team Set II 2021 is the old 255 TailWing (with inscription TailWing 255). Which spacer should I use, to get the same rake as the new 255 -2 TailWing? The -2?
Thanks.

i use the -2 spacer with the original 0 stabilizer, that should be the same as 0 spacer with -2 stabilizer.
TAIL WING ADJUSTMENT
iQFOiL sets are supplied with six angle spacers (-2? / -1.5? / -1? / -0.5? / 0? / +1?) and with a new 255 tail wing that has -2? built in.
The recommended tail wing angle on the 115 Plus is -2?, so we recommend starting with the 0? spacer. For the 95 Plus the recommend tail angle is -1?, so we recommend starting with the +1?, spacer. You can reduce tail wing angle for more speed and control, or increase for more power.
