Andreas, Thomas Singer, Wolfgang Klur and others were all using it at the Formation Cup and have had no issues. It was in Jets and their big Moki P-47 and Corsair, the Skygate L-39's CARF Viper's etc. There is not a system on the market that someone has not had an issue with!
Tx looks high quality, I've not handled one so can't comment, but it must be better than many of the "toy" feeling radios I have handled recently!
