I have a older 3PK with Spectrum module and it has worked great since i bought it used in the summer but now I am having issues. Anyway when I turn wheel all the way to the right the screen cuts out and it glitches for a couple seconds also after it does that a couple times it displays a main memory error on the transmitter screen. This is probably the end of the transmitter but I was curious if anyone else has had a similar issue and figured out what caused it? I use this tx for both my rc and it is doing the same thing with both vechicles. Any input/help on this issue would be great! Thanks Again!
