52 Additional info: What swash mixing
is required for my helicopter?
Today most helicopters use a 120° swashplate, i.e. all ALIGN T-Rex helicopters as well as
SAB Goblin, Mikado Logo, MSH Protos and many more.
Mechanical mixing was very common on Thunder Tiger Raptor helicopters and Vario scale
or trainer machines but is getting rare today.
The type 135°/140° (1:1) is the most common type of ”140° degrees” swashplates. Often it is
also considered as 135° swashplate! There is no uniform designation for this type of swash
mixing. The main idea with this type of swashplate is to have an equal servo ratio on the
elevator axis, which will remove the collective interaction due to unequal servo movement
and in consequence will give a extremely precise control of the heli. If this is the case on
your helicopter (elevator and aileron servos are moving the same distance when steering
elevator) then choose this type, no matter whether it‘s called 135° or 140° swashplate. You
can find this type of swashplate for example on Shape, JR and Hirobo helicopters.
