75mhz radio questions
Good day everyone have a few questions for all of you experts.. All of my RC experience up till now has all been with 2.4 GHz transmitters and receivers. With that said I do have interest in going into some vintage RC boats and possibly submergeable submarines. My understanding is the my understanding is these best run off of 75mhz radios and transmitters. Looking for used 5 plus channel radios everything seems to be in the 72 MHz frequency. Question would be what 75mhz radios can you all recommend with at least 5 channels channels new or used reused I have only looked on eBay and the classified section here on this website. Where else could you all recommend looking to to pick up radio? And what type/brand would you also recommend or stay away from ?
Thank you !
