Just to clarify. Kris was super patient and understanding regards this all. I still think it may have been something in the set up. I really should have found time to have gone through it all. Sorry once again. Also just for clarity. I still rate the cortex as a great product. I think I still have at least one of my planes flying with one fitted, as well as flying a bunch of my friends planes with them fitted. I have nothing negative to say about them what so ever. I do prefer the 3e ( for a number of reasons ) but I fully appreciate and understand that others out there may prefer the cortex. Thats one of the things that makes this hobby so great. The progression and the diversity of equipment. I am sure at some point a product will come along that will be superior to both of these units. Till then. I thank both manufactures for making products that work so well and make our toy planes more enjoyable to fly!
