Hi Billie. I picked up a new Hitech FM HFS-03Mt 3 Channel Aggressor, and cant locate any Channel 64 75.470 Mhz crystals in the Edmonton Alberta Canada region. According to your website the crystals are... Red tab

Rx 6687564 and Tx 6717564
I have checked every hobby shop in the region and no one has the crystals in stock and are looking at up to a month to bring them in "Special Order", My question is "can I use a different channel set???"

The Ground control unit came with one servo, I am using it on the throttle, as I have the Hitech 985MG on the steering.
It is on my Revo with the OS 30 engine .
