hey , you know me Ben, I never let ANYTHING go

Very good move by JetCat to publicly address these issue. I hope any other manufacturers experiencing these or other unexplainable issues also come forward in helping find a solution.
Matt answers a lot of questions about the issues in his letter, and provides some VERY GOOD points. I know i will be keeping a lot of these in mind rigging my planes. I’m really looking forward to the up coming Jetpower issues which will hopefully contain more info on this as Matt has indicated.
I was also glad to hear that the ECUs have not changed physically since the 5.0 versions. I had heard through reps that certain new chips may have been used in 5.0 and later contributing to the ECUs susceptibility to take a hit, and aparently this was incorrect information being passed on. I still have some 4.0 ECUs ( all for heli units) which I feel more confident now in getting them updated to 5.0 .
I suspect some time in the near future someone will start a thread dedicated to ESD issues, and maybe we can all collectively and more productively share points and ideas on dealing with this,
all the best ,
