ErichF, Do you have any further information about a future update for the 8fg to get telemetry? This could be a big deciding factor for me. I could then have the best of both worlds minus modelmatch.

If the upgrade were coming within a few months I would probably just get the 8fg. If it is a year out I think I will have a much harder decision to make.

I am still going through making a list in a spreadsheet of features that are important to me to compare all the mid range transmitters.

My trex 700e f3c V2 came in at the hobby shop today so I am excited .

I don't, sorry. Maybe I will get more info at the Nats or IRCHA. I'm not an official member of team Futaba, so I don't get the scoop...or if I do, I am sworn to secrecy

Do the 8FG has the receiver built in for telemetry?

I doubt it but I don't know. But I know there is a difference in transmitting and receiving.

Does the 8FG have zero swash plate interaction or do you need to mix to compensate?

Rumors say yes the 8FG does have bi-directional communication ability.

I just wish someone would announce something already so I can make my Transmitter purchase decision .

The best tx decision is never having to buy another one. Having some resale value when you're thru is another. Having every option is valuable if you switch disciplines; jets, gliders,etc...

Any measureable or perceived eCCPM interaction in an 8FG controlled model does not come from the radio. The system will be as interaction-free as the servos and mechanic will allow.

Well the decision has been made. It was very difficult.

I decided against the DX8. In the end I was still a bit scared of the DX8. It is possible everything is fixed with new DX8's that you can purchase now but I could not find enough comments in the forums to confirm that for me though. This was a hard conclusion for me to come to because my DX7 and DX7se worked so well. I will have to evaluate their next transmitters a year from now and maybe decide to get back into them again because I liked the programming and features. If none of the issues came up with the DX8 I would have probably just lived with the more limited eCCPM tweaking of the DX8 for all the other features(Telemetry and modelmatch mainly). I do hope they incorporate more eCCPM tweaking functionality in the future!

I decided against the Aurora 9. This is a shame too because I really liked everything I read about this transmitter. Built in RX voltage telemetry in the receiver! Very customizable and very intuitive touch screen interface. The thing that mainly stopped me from buying is the speed is slower than all the others and others that tested it compared to others mentioned that you could feel the difference going to a faster transmitter. I assume this could affect the eCCPM interaction too based on the fact that it would take slightly longer for the heli swash to move. I am no expert or even slightly knowledgeable to really know how much that is true or noticable but that kept bugging me in the back of my mind thinking that other transmitters would be faster. I didn't want to spend my money and get the slowest one out there of the 2.4ghz transmitters. If this transmitter were at least closer to the speed of Spektrum or Futaba I would have bought this one over Spektrum or Futaba for sure. The design is a little boring and old school but I could overlook that for features. It is possible that the speed would not have mattered and I made a mistake not getting it. I know I will always be thinking that in the future.

I decided against the Airtronics SD-10G. That was mainly because it is more of an unknown to me and was harder to find info on it, I didn't see any special features that stood out to me and they didn't have any possibility of telemetry. I am also concerned about the shiny case blinding me in the sun . There were no special features that really made me want to push for this transmitter except for speed. From what I could gather though this transmitter is very customizable too. I do remember reading some things about the programming that I didn't like but I actually don't remember what they were :/.

The most important feature to me is getting rid of eCCPM interactions. From all the reading I could find on the subject it seems like Futaba 8FG Super has the best features for that so based on that and all the other things I mentioned about the other radios I ended up buying the 8FG Super. With a rumor that it will have telemetry features soon that helped make up my mind. I will miss modelmatch but I don't expect to have another Heli for awhile anyway.

So the winner is the 8FG Super. Congrats to all the radios that tried to win me over... they all sound like good radios but I think 8FG Super is the one for me. If I were flying flybarless only I would have probably chose the DX8 even with it's track record. Getting the best eCCPM tweaking features are just too important to me right now though. I bought it online for $404 new with the R6208SB receiver.

There is no doubt that I will be second guessing my decision for quite some time especially if the 8FG Super does not get telemetry features anytime soon.

Now I am fully expecting to hear about this telemetry upgrade after you come back from NATS ErichF!

Selectively quoting you to get what I want to hear and cutting out the parts I don't . My wife tells me I am good at that when it comes to listening.

"Telemetry from Futaba is not for away, and will be compatible with the 8FG following a user field upgrade"
"I will get more info at the Nats or IRCHA"
"I am sworn to secrecy"

And now that I will have an 8FG Super Does that mean I can get help now Mr ErichF? .

We'll see telemetry on the 8FG sooner than you think. Here's why I think so:

The 18MZ is due out soon, and that thing for sure will have telemetry built into it. Futaba will most likely want to release that thing with telemetry technology and package a FASSTest receiver in the box with it so they can showcase the new technology.
It's just one of those things.

If the 8FG is indeed capable of telemetry technology with only a firmware upgrade as many are now speculating, we won't see that update until AFTER the 18MZ hits the streets and not a day before.

So now the big question is-- When will the 18MZ be out? Soon. Per Steve Kaluf,
We do expect to see it late summer/early fall. Please remember, this is a major release; dates are subject to change.
If it's really that close, I expect to see a working prototype or two at the Futaba tent.

Congrats on your new purchase of the 8FGH-S. I would be more than happy to help out as I can. Will you be coming up to the North Central FL funfly in Sept? It's just outside Gainesville here. Look it up on the Events forum.

Let's just say 'by the end of the year' for the 18MZ. All of the earth shaking action in Japan hasn't helped anything. When Steve left Muncie at the conclusion of the F3A Championships, he was (and still is) hoping to have more information on the 18MZ by the time he arrives at Muncie next week for IRCHA. We keep hearing November time frame.

just what is this silly talk about telemetry?

we're not running a F1 car where we have a team behind the driver to tell him what's going on are we?

as far as I'm concerned, and another person I know agrees too, my only reason for getting the 18MZ would be better software and reduced latency and also putting an RX battery low voltage alarm on the transmitter to warn me when it's about to go south!! That's as far as I am interested in telemetry.

And besides I can't see sending all this data back to the transmitter be a good thing, aren't our airwaves getting flooded enough already?

Keep in mind RC Helicopters account for a very small percentage of Radio Control hobbyists.

I think of a whole list of reasons airplane pilots would like telemetry. 1) Fuel level in a glow powered plane, 2) altitude in a thermal soaring glider, 3) airspeed in a pylon racer or a jet. Keep in mind airplane pilots can actually afford to take their eyes of their model for a few seconds.

I just got the head setup. I finally wrapped my head around the setup FAQ on the futaba site (written by Ben something I think). After experimenting I decided to do things a little differently but very close to it. I really didn't fully understand it all until I experimented with all the settings one by one to see how they actually behave and how best to detect the movement.

All I can say is I am glad I chose this radio. Dialing out eCCPM as much swash interactions as you can can be tricky but seems like it will pay off based on my results on the bench.

I ended up using a swash leveler for the pit->ail and pit->ele part of it(equivalent to doing EPV on DX7). I then turned the pitch leveler upside down but filed it a little where it sits on the swash ball upside-down (so that the swash didn't hit the leveler at elevator and aileron extreme inputs). I was then able to put a dial indicator on the top of the leveler and see any up or down movement by the swash ball while I worked out interactions at top and bottom with ele->pit and ail->pit. I was then able to use the same leveler and dial indicator setup for the swash compensation adjustments. All of this was done with the head off above the swash.

After I did that I put the head on where I was very precise with the link lengths. Compared to my 600 that I set up 3 or so years ago I don't see hardly any interaction in the head. Moving the elevator and aileron stick around pretty fast at 3/4 and full max pitch the swash does not move up and down hardly at all (maybe 5 thousands). Moving an individual input results in a variance of only about 2 thousands and better. I can only wonder how close I could have got it with BLS252 on the cyclic instead of the DS620. Ihave a feeling I could get it to about 3 thousands for fast combined elevator and aileron movement and maybe 1 thousandth for individual or slow movement. One day I might just have to find out if I can get som BLS252 for a cheap price one day.

There are some tricks I learned but i think most of them I couldn't explain if my life depended on it . The main thing was the swash leveler upside down to dial indicate the ball movement up/down. Another was to wiggle the stick back and forth very slightly to see where the average location was when trying to make sure the location stayed the same.

I am just glad I resisted the DX8. Now if the DX10 gets these features though I might sell the 8FG Super . I really don't care about brand loyalty. I just want the transmitter that has the features I want the most. CCPM interaction features is at the top of my list.

Congrats on the new toy
3) airspeed in a pylon racer or a jet. Keep in mind airplane pilots can actually afford to take their eyes of their model for a few seconds.
For real Dood?

I've flown both, there is not time to think at 100plus let alone at 200mph. If you need to look down is because the racer reached 0mph. Don't need telemetry for that, you can see IT.

I have said it before, if someone needs altitude, speed, RPM, or voltage information, use a logger.
SO whats next? Texting and Twiter button on the transmiter so one can blog, "hey! Im a flying, oh crap, I'm crashing..."

Plank Fuel tank level? With all the splashing? Maybe if you fly straight and level all the time. I use my ears for that, when the engine make no more noise is time to land.

An RX low voltage alarm would be usefull.

Hey, I'm just speculating how telemetry could be used for rc aircraft.. Not that I've ever used telemetry on an rc aircraft (yet). But I hope you agree that telemetry has to be marketed more for planks than helicopters.

I certainly could take my eyes off a plank for a second, provided I'm straight and level. I've got a few fast planks that I would definitely love to be able to see their speed at a glance.

For fuel level- definitely! I don't like dead sticks. I've got a highly maneuverable 3D plane that can glide at just a few knots. I'm not worried about that.. I worry about those fast planks with the long skinny wings like the Shoestring that don't like to glide any slower than about 25kts. My field is a grass strip with about 360 feet of usuable runway with a hill and a bunch of crap on the west end. The field I fly at is not deadstick friendly with fast, heavy airplanes that don't glide slow.
It's hard enough as it is to land those planes under power.
