Ok, sorry but it's "stupid question" time.
I've seen converted KO Esprit 3 transmitters, but is it really necessary ?
If I'm correct the Spectrum SM1001 works on a KO Esprit III, and also it apparently also works in a Futaba 3PK transmitter.
So is it needed to really convert a KO transmitter or has anyone tried ( or is it worth a try ) to use a FRSky Futaba combo on a KO Esprit III ?
(or maybe even slap in a complete original Futaba module

)
