What do you do if your frequency isn't open?
What do you do if your frequency isn't open when you get to the field?
I have a Hitec Flash 5, and it looks like the only way to change the TX crystal is by sending it in to Hitec. (I've read through all the debates on the other threads).
So, is the only other way to go around this is to get another TX with a different freq, and a set of RX crystals using that freq?
Or is there any other options?
I would hate to get to the field and find out that my freq isn't open.
