Been considering this radio, as it's really affordable. Anyone have some experience with it yet?

Any Latency tests? Or user reports in a heli by someone NOT sponsored by Airtronics?

There is a long thread about this radio on RCUniverse.

I was looking at this- it has excellent speed (low latency), and a good following- I think its an excellent value and would have gotten one but found a DX7 used for a very good price.

JKos has done up a good long thread on latency testing- I believe the RD8000 (72mHz version) has the same latency as the Stylus-
excellent:

Search turned up this thread:

http://runryder.com/t404751p1/?highlight=rDS8000

I asked around and it was purported that this 2.4gHz version has the same characteristics.

Have at it!

Never, ever, ever, ever give up.

Remember one thing about the RD Series radios. While it has CCPM, this radio has a real basic version of CCPM. It doesn't have all the necessary tuning techniques that other radios may have. The Stylus can make the swashplate go straight up and down but even that radio has limitations as well. You still need a heli with good CCPM mechanics and if you do have one the RD will work just fine. I fly the RD Series on a lot of different CCPM machines and have never had to tweak the setups, just set the center and the CCPM limits in the radio and go fly. On a Raptor or an EVO you can't beat this radio for performance. I'm currently using RD Series on a Mini Titan, Raptor 50 and EVO 50 and it is real smooth.

Brian originally wanted a non sponsored pilot to respond but I just want to make sure that you don't expect the world out of a $229.00 radio. Take it for what it is.

As far as the latency is concerned I know that JKos is going to test one and I for one am eagerly awaiting the results of his testing.

A friend of mine has one for his T-Rex 600N Sport, and I've flown it, and it feels fine. It was a little weird programming it, as most of my experience is with Futaba, but we managed to get it working pretty well.

I think it's a great value radio in terms of cost/performance. I just wish there was a heli specific one, as the switches are not where I would like them.

Thanks guys, I realize that as far as funtionality, this radio might be somewhat limited. It seems to be a great value though, so I think i'm going to give it a try. My only real concern is with my Fury, which is a 140 degree ccpm. If I have a lot of trouble, I'll probably use a csm cyclock at lease with it.

Anyone have any experience using a mix to use 140 degree ccpm?

I just wanted to add, the switch issue I noted is easily corrected by the end user, and I understand that Airtronics provides for this in the box with the radio.

RDS8000
Changing the switches is a breeze and outlined in the manual.

Programming is easy once you understand the flow. Think of the menu as a drop down menu within a computer program. You could also think of it as rows and columns like in Microsoft Excel. You can move left/right and up/down from any point in the menu.

I don't plan on running a high voltage "crack" set up on my machines, so the 6v limit of the receiver is not an issue. If you want to run unregulated 2-3cell lithiums to your servos, you may be limited. I honestly prefer to run a 5.1 or 5.7v regulator for everything.

I going to test fly this radio with the cyclock as soon as the weather breaks. My synergy is prgrammed and charged. Come on Spring!!

I came from the DX7 and I appreciate the added channel found on the RDS8000. This makes setting up an onboard glow system, like the switchglo, a breeze. I found a way to do it with the DX7, but the 8th channel makes is straight forward and MUCH more effective.

I also found the servo feel to be more linear with the RDS8000. Response around center stick is quicker and requires me to run a little more expo than I did with the DX7. After getting use to the faster response I could remove some of the expo and take advantage of the reduced stick travel for my manuevers.

Battery life on the stock battery is very pleasing, especially for a 600mah nicad. I could never fast charge my DX7, but with Nicads I can.

Binding is easier and faster. No silly bind plug to use and I don't have to remove any wires from the receiver to install a plug. Also, no plug to forget in the receiver after binding.

No remote antennae to mount.

No junk servos to buy and then resell at a loss.

Just outfitted my TREX 450SE with the RDS8000 2.4.
I fly the Raptor fleet on my 9ZWC2. I wanted a radio I could throw in the case for the TREX and not worry about it, as I sometimes travel with it (although Lithium issues and TSA is a bit of a problem now).
I had been using my 9CHPS for the TREX, and did not like the feel due to CCPM setup and the 9C.
I got a really good deal through a buddy's hobby show on a RDS8000 introductory offer and could not pass it up.

Setup was pretty straight forward. I did the switch change to make the flight mode and hold switches on opposite side and put make it so Normal and Hold off are "both switches back" to match my Futaba gear.

Once I setup curves and flight modes I did another bind routine to get my gyro settings right to boot up in HH mode, then took it out to fly. Overall I rate it as very good. The sticks are not as silky as my 9Z, but every bit as nice as my 9C. The TREX felt very smooth, and control response was great. I too had to dial in a bit more expo to get the center a bit softer (+25%).

Overall I rate this one a keeper. A the price of the radio, and even more so the price for 8 channel 2.4 receivers, it cannot be beat when compared to the Spektrum.

Tyler and Jim,

I'm glad y'all like the programming as it is one of my faves too. That's a good point about being like pull downs in a Windows program. Just wait until the next radio comes out.

Competition is good for us. I hope Airtronics get's their stuff up to date and at least competitive with the X9303 and 10C. This requires some graphics for curves, mixers, etc. At least 7 point SPLINE curves are needed and of course, CCPM swashplate compensation.

Does the new RDS8000 have more than 2 programable mixes now compared to the old RD 8000. I had a RD8000 for many years and loved it, but went to a X9303 2.4 for obvious reasons.
I loved the old Airtronics and found it super easy to program as I do the my new JR. The DX7 makes me scratch my head though to program my friends radio/.

Setup is everything, All my heli's can fly far better than I can pilot them

from what I understand the programming is exactly the same as the 72mhz version, no changes.

Before I got a GOV on my Raptor 30 I programed elevator /throttle and airleron /throttle,, but I did want tail rotor /throttle mix too but couldn't do it.
On my old Xcell Gasser I needed at least 2 mixes to cancel out swashplate problems

So far I have not seen much as far as interaction that needs correction, and yes, I do run a governor, so no need for tail to throttle
