Why aren't more Rx's antenna-less ?

Nice conversation topic by the way
Always nice to engage in friendly open discussions about our hobby!

I don't wish to sound like an opponent to 2.4ghz, in fact I love it! Its just that it is different than the other frequencies and knowing how to deal with its strengths and weaknesses is good info to share. Add to that the different types of spread system technology out there-well you know.

Having been a ham radio guy most my life, having a good antenna setup is one of the most important keys to making the most of what you have. I kinda wish rx's(and tx's) could be more modular with antennas that can be added or replaced more easily. But then again we are a very very small market.

Your right about 2.4ghz users being low power, but there are alot of them out there.
Every pond or lake that our club uses throughout the season we always are wondering why some locations are worse than others. Is it that steel light pole? Could it be that metal railing on the dock? Try holding your radio above your head! It must be from that large apartment complex

I'm with you proper! I get range with the tactic that is so good that if it was any further away I couldn't see the boat anyway! I think the range question is a cop out.

Thanks, Bill-glad you chimed in. I'll admit that my testing of the Tactic's been limited to Legg Lake where there have been no range/glitch problems. Other locations may not be as optimum. FWIW, I just re-installed the Futaba 3PM in my mono racer in prep for February.

To be honest, I think a quality FM system is better as far as water reflection issues and body materials are concered. I have both 75 Mhz and 2.4 Ghz systems and as previously mentioned the clash probelms with FM are resolved with 2.4 Ghz systems which is it is huge benefit.

Agreed. 2.4 is a bit different from what we are used to and takes some re-education to fully understand the limitations. Having said that, I think it is way more than worth it to never have to worry about being shot down or run aground due to some nimrod turning on while you have the pin.

I also very much enjoy the reduction in concerns about internally generated RF. It can still be hit by internally generated nosie, but metal to metal, ignition noise, etc. are a thing of the past. The 2.4 gig stuff is also essentially immune to vibration since it is all SMT with no crystals or IF cans to get rattled about.

And the tiny size, especially for the airborne stuff just makes me giggle. My 8-channel FASST RX almost gets lost inside my 2-meter pattern plane. And forget about a 40% plane. I tie a broom handle to it so I can find it!!!

You are spot on Bill. It doesn't take but a few years when those problems were still causing too many headaches and accidents.
Our club is still about 50/50 between the 2.4ghz and the 75mhz. I guess you could say that having enough of the 2.4ghz around also frees up the ones who still use 75mhz and will continue to do so until they need replacing.
From what I've seen, it seems the only thing from keeping the rx's from getting any smaller is the servo connectors! I am sure there is alot more development continuing out there as well.
