So, my conclusion so far is that the Futaba 9Z appears to be the only Tx that supports this feature. (Certainly the only on for which I have evidence of it being supported.)

I have spoken with 2 MZ owners whom I thought were doing this, but it transpires they are using one or more stick position triggers to adjust rates in discrete steps. This is supported on pretty much all of the high-end Txs I have looked at.

Thanks for all the input,

HS

My conclusion is wrong - see below [X(]
