BTW, the idea that opening up a TX automatically voids the warranty needs to be explored.
The instruction manual that came with my Futaba has a section that explains how to tighten the gimbal springs and suggest replacing them with stronger ones if tightening isn't adequate. I also notice that the case screws, that years ago were "sealed" with paint to indicate whether or not the TX had been opened, are not sealed nowadays. I would suggest that opening the case no longer affects the warranty at all.
I agree that opening a Tx is a necessary thing. The INTERLINK, however, is NOT a Tx... it's a dongle that serves as copy protection for the software. If KE allowed anyone to open the box, their proprietary copy protection would be invalid.
Anyone remember the old Packard Bell PC's they put out in the early 90's? The things were painted shut, with big warning stickers about voiding your warranty if you opened the box. Problem was, I worked for an ISP that would install a free modem or NIC when you signed up for service. So here we are, adding to the capabilities of users' machines, but voiding Packard Bell warranties every day doing it...
