Whats the different I know FHSS is frequency hopping so like every 5 min it changes it channel, but whats the advantage over spektrum. Is it true that a spektrum dx3 will go into safe mode during a race if someone turns on another radio on the same frequency?

Basically what makes the spektrum dx3 bad?

qaiz

Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver.

A spread-spectrum transmission offers three main advantages over a fixed-frequency transmission:

Spread-spectrum signals are highly resistant to narrowband interference. The process of re-collecting a spread signal spreads out the interfering signal, causing it to recede into the background.
Spread-spectrum signals are difficult to intercept. A frequency-hop spread-spectrum signal simply sounds like an increase in the background noise to a narrowband receiver.
Spread-spectrum transmissions can share a frequency band with many types of conventional transmissions with minimal interference. The spread-spectrum signals add minimal noise to the narrow-frequency communications, and vice versa. As a result, bandwidth can be utilized more efficiently

Also forgot to mention.

Spektrum radios run on ISM bands, you would'nt wanna be any where close to a power plant when using one of those.

okay thanks, but does that mean that spektrum radios dont go into failsafe mode?

qaiz

That I have no idea, but I think they have a built in fail safe.

slayerphonics

Built in programable fail safe in specktrums

bmwnla

yes i know they have a fail safe. Im just wondering if say im racing at the track with 60 other guys around with their spektrum radios on. Will I ever experience any problems?

bmwnla sorry for invading but how is the DX2.0?????

bigairlife

I have a mx-3 FHSS 2.4 ghz and i'd say it's one of the best radios i've ever used. Way better than my spektrum on my old savage (sold). It's changes frequecy like 2-3 times every second (i think it could be 4 or 5, not sure), and it has a great radge of features. It also has a built in failsafe. Plus, it's not too expensive =-]

I have never had any issues with my dx3 going into safe mode while racing and ive raced a few races with over 80 participants alot were using spektrum radios. what happens is when you turn your radio on it locks on to an open signal and nobody else can use that signal. I believe the new dx3r uses a newer system I forget.

bigairlife

If you get a spektrum, get the dx3r, but i'd just go for the mx-3 fhss.

my buddy may be selling me a dx3 with 3 recievers for like 90 bucks........this is why im asking

HpiDrifter420

take the dx3 for 90 bucks thats good deal if it isnt beat up

Vigilante212

the 3 recievers are worth it for the 90 if they all work.

bmwnla

i kno thats what i was saying
