Seems there has been some development on the Deviation Forum- The Walkera Devo 7E has sprouted some twiddly knobs and gained some extra channels.
See the post onĀ Deviation TX forum
Not to be left out I have gone and ordered an Adruino, A USB TTL programmer thingy and a bag of pots…stay tuned & don’t touch that dial….yet (still on the slow boat from China)
