I'm new to Spektrum (just got a used DX7) and need to buy a receiver. Currently, what's the best rx for 500 sized and larger helicopters? I don't need a top of the line rx, just something with a good balance between price/reliability.

Also, aside from the parkflyer stuff, what are the receivers to avoid? I may run into a good deal on a used rx but want to know what I should avoid. I've kinda been away from the hobby but remember reading about brown outs, etc.

Thanks!
Scot

AR7000 is a good choice for a 500. They've been around for a while and can be had for a good price. Plus, with the satellite you get path diversity - something you don't get with the park flyer receivers.

Ar7000 and up...
Anything from the ar7000 on up. Any of those should work for both electric's and nitro's. The 7100r has a built in rev limiter and all the 7100's have a voltage regulator built in, the 7000 does not.

Is the AR7010 a good, solid receiver? I don't need any special features, just reliable and hopefully nothing that will hurt performance.

Just thought of another question...are some Spektrum receivers faster than others?

Some Spectrum RX's...
Can take advantage of the faster Transmitters. If you are running a DX7 your transfer rate is at 22 milliseconds(also called latency, it's the amount of time that you have between stick to servo movement, the smaller the number the faster the TX, it's what helps you feel more connected). If the DX7SE then the 11 millisecond rate. Does the AR7010 have the sattalite receiver? You will want the extra coverage especially if your flying a CF machine. Carbon can block signals at times.

Thanks again for the info! Are some Spektrum receivers faster than others? I know some Futaba rxs are better than others.

To expand on Barracuda's post -- the AR7010 is an AR7000, but it uses DSMx instead of DSM.

Yes, the 7010 will work just fine with your DX7, but unless you have the DX7 upgraded to DSMx, you won't get the frequency hopping feature that DSMx provides. Is that bad? No, unless you intend to go flying in places where the 2.4 GHz band is fully saturated with all sorts of other 2.4 GHz signals -- other radios, other brands of 2.4 GHz radios, WiFi everywhere...places like huge gatherings such as IRCHA, Joe Nall, SEFF...

The 7010 has a satellite just as the 7000 does. Your DX7 transmitter has a 22 msec frame rate, a "faster" receiver would do you no good. Had you purchased a DX7 SE, then you could take advantage of its 11 msec frame rate

An AR7000 on a Trex 500 works great, the 7010 would be just as good.

As an aside, I found out an interesting tidbit, with the 11ms setup that only applies to the cyclic servos (ail, ele, Aux1) the rest run at 22ms. I never knew that.

Its not so much a reciever function, as the transmitter so as he said, yes any 11ms setup

Okay, thanks guys. Just to clarify, the AR7010 can operate at the fastest speed as any other Spektrum rx IF your tx is capable, i.e. DX7SE? I may upgrade to a better tx at a later date so don't want to buy any rxs that won't be able to take advantage of that.

no reason you can't use a full range 6 channel receiver. if you go nitro later on and want a governor is when there a need for a 7th channel. you might save a few dollars on a used receiver, but given that it is the brain of your dollars, probably best to buy new.
