Loading Basic Parameters

Using APM planner for the first time on my Mac via Mavlink and it appears great.

However I was wondering if someone could tell me how you are suppose to write update parameters in the Basic Param menu to the FC?

I was changing the command on Ch 7 but the only way I seemed to be able to get it to update the FC was to close APM Planner after doing the update and then re-connecting via the Mavlink.

I can’t see a Save or Write button /command in the Parameters screen.

Thanks for any advice

in Basic Tuning updates are sent instantly to the vehicle. If changes took, or did not, it will be reflected.
There’s not ‘write’ or ‘save’ function

Thanks Bill
