To Synthesize or not to Synthesize

[rustnpede]

Without much room to mount electronics, I was wondering how much interference you get with these monster motors, esc and Rx mounted so close together. I’m going to buy a new rx and tx for my bl revo and was debating on whether or not to get a synthesized setup. I don’t plan on racing so finding an open frequency isn’t a concern. Will a basic fm set up suffice?
