Default FM advantages over 2.4GHz???

Hi, What advantages has the FM technology opver 2.4GHZ???? More control?
Of course with 2.4 you've got no worries about frecuencies, but many drivers still use FM.... whe nthey can afford 2.4......

Is FM better, except for the frecuency things??

Thanks

maybe slightly faster response times (not noticeable though). other than that all I can think of is that there are hardly any stick type 2.4ghz transmitters out there.

FM has no advantage over 2.4 gig. DSM does everything FM does at a frequency far away from any potential interference.

If you can afford it, get DSM. IF you have FM, keep it for now it's still good and you don't have to worry about frequency conflicts as much since everyone else is on DSM (thanks, guys! )

More and more stick radios are being made available with DSM

Both Futaba 3PM 2.4GHz or Sanwa/Airtronics MX-3 2.4G are quite cheap both! I'd take Sanwa/Airtronics, as Futaba has some problems with FASST.

If you're on a budget the 3pm FM is a good radio. There's also a 3pm DSM which isn't that much more.

Whatever your budget allows.

Depending on track location, there may be certain frequencies within the 2.4 band that are also used by other devices. Wireless internet, wireless computer components, telephones, etc. For the same reason these devices often interfere with each other, they interfere with the 2.4 radio systems. If you happen to go to a track where there's interferance, you can't do anything about it when you're on 2.4. You can't change freqs like on 75, you're just screwed.

Take a look at the driver's stand from the 2008 8th scales worlds at The Farm II in Charlotte NC. Every single driver in the A main is using 75mhz. The track is plagued by 2.4 interferance.

If you're going to race at one or two tracks, find out if anyone else has problems there. If you're going to travel to races every now and then you would probably be best off with a synthesized 75mhz system.

Noticed brushless system emits more noise interference more than brushed. Safer to use 2.4 ghz on brushless than fm.

FM is still usable, in fact i still use it. I have a Futaba 3pm and it works just fine. I dont have any issues with interference, whether it be brushed or BL.

The guys you see probably still use thier controllers because of feel. Whenever you change you controller, your feel goes out the window until you get used to it.

Cheers!

I've switched my Futaba 3PK from Spektrum to FASST and I've never looked back. I don't know personally of any drivers having issues with FASST. Go on Futaba's website. Turns out they have been using 2.4GhZ systems for 15 yrs in their industrial radio control applications.

Save up and possibly look for something used on here in the marketplace, you never know what you might find. ou do not always need the latest technology, and as stated you can pretty much run FM without worry of needing other crystals with everyonelse going too DSM.
