Antenna routing
Noob here. How are you guys routing your shorty Rx antennas? I don’t see many guys running antenna tubes anymore. Is the antenna just loose? Or is everyone just running antenna-less receivers? I see the newest Sanwa Rx for the M17 (491) has returned to having an external antenna, did the antenna-less 481, and 482 not work that well?

My local track isn't that big, but I don't route the antenna out of the body. I just bundle it with the rest of the wiring and tuck it out of place. I haven't had any issues with distance on my local track, but again, it's not a large track. I'm not using Sanwa gear though so YMMV.

There is allready a lot written about the differences between antenna less and reacievers with an antenna
Basically the antenna less receivers are advised voor electric because those tracks are smaller. Such a receiver mounted in a gas car it will be surrounded by aluminum and carbon that can give range isues. So when running small tracks and electric (more open chassis) the antenna less is fine. When running gas on large tracks it is advisable to use a receiver with an antenna although there are many reports of no issues with an antenna less receiver, to me it is still a risk with such a choice..

I use "antennaless" receivers for my nitro buggy and it's fine, even on large tracks such as Thornhill. But that's with a FlySky NB4 so your experience might vary with other radios.
For my ebuggy I used a lighter to bend the antenna so it stays under the body. It's a shorter 2.4ghz antenna. I know that isn't ideal but it hasn't caused any issues for me.

Here’s how I set mine up. I figured since there was a place to use an antenna tube, might as well use it. I cut the tube a little shorter than the antenna so I could use the cap to hold it in place. Once I had it in place, I heated up the tube and bent it so it would fit under the body.

External antenna receivers can work for all cars (nitro, electric, large track, small) so I imagine they prioritize releasing these receivers first. Then then new generation of internal antenna receivers will be released.
You can still run the 481/482 or their clones with the M17, just losing whatever fraction of improved response you'd get with the new receivers if running Sanwa servo and ESC.

I had some glitching when I had it routed over my esc and motor. Other than try and keep it away from that, it doesn't seem to matter much otherwise.

As noted on the picture above, even antenna’d receivers have pretty short leads. So in most cases, you can easily keep the little antenna tube tucked inside the body. If you happen to be running touring car, it’s a piece of cake.
