Profile (Bank) switching example

Purpose​

info

We often configure several flight modes to suit our own flying requirements e.g. (Futaba - Normal, IU1, IU2)(OpenTx - FM1, FM2, FM3). It is quite possible that with each of these flight modes we would want to adjust and tune the model independently. We can do this through the Adjustments tab. This is a similar feature to V-bar 'Bank switching'. The following example is just a suggestion and is one way to go about using the adjustments tab. The same process can be used to switch rates if required.

Aim​

My helicopter has already been set up to have a 3 position switch (SwE) which selects between 3 headspeeds (I use the governor so my 'curves' are just flat). The following example will add switching of tuning parameters (Profile Tab) for each of these headspeeds.

Configure the Tx​

We need to assign a spare channel to your 3 position switch (SwE) (can be any channel or switch).

NOTE This example shows the process for EdgeTx (same for OpenTX) but is really the same process for any transmitter.

Step 1: Assign Ch9 to the SwE in the Mixers tab

Step 2: looking at the channels in the receiver tab we can see that Aux4 is the ninth channel. This matches our TX assignment from step 1. Confirm the 3 position switch changes the value seen on Aux4,

Step 3:

  • Go to the Adjustments tab. Enable an adjustment slot by selecting Mapped and select Aux4 as the Enable Channel and Value Channel.
  • Stretch the Enable Channel and Value Channel sliders across the entire channel range. This covers the positions for each of the three switch positions.
  • Select Profile Selection from the dropdown. This means we want to change the 'Profile selection' by the switch position.
  • Stretch the Profile Selection slider from 1 to 3, This means over the defined range a value of 1-3 will be chosen based on the switch position. (e.g. SwE down = 0, SwE middle = 1, SwE up = 2). These values are added to the Profile so will result in (e.g. SwE down = Profile 1, SwE middle = Profile 2, SwE up = Profile 3).

Change Profiles

Step 4: Go to the Profiles tab and test and confirm that changing the switch position results in changing of the current Profile.
