Status: offline 		So either the chart is wrong, or the manual is wrong or the spec sheets are wrong. While you're pointing out these issues to them could you also raise issues with the relevance of the website. its out of date. The R2008Sb link still takes you to the R2006GS Rx page.
Servo's need updating because Tower already shows servo's about to be stocked.

Status: offline 		The confusion seems to be coming from the fact that the R2006GS can be used with both the 4PL transmitter and the 6J transmitter.

The 4PL has what is called an HS mode, that is not found in the 6J. In this HS mode, you MUST use Digital servos.

Maybe this chart on our website will help you all out:

http://www.futabarc.com/receivers/fhss-s-fhss-compat.html

http://www.futabarc.com/receivers/fhss-sfhss-compare.html

The basic answer is:

You CAN use analog servos with S-FHSS.

Under what circumstances would you choose one mode over the other?
What are advantages and disadvantages of each?

Status: offline 		You would want to choose S-FHSS when you need the higher frame rate, FHSS is slightly slower.

It's really hard to say, but if you are flying a heli, you would most likely want the S-FHSS for it's higher frame rate, a park flyer, maybe not so much, an FHSS would suffice. But it also would depend on what receiver you want to use or can afford.

Krysta you're saying S-FHSS is a slightly higher frame rate.
But HS is also a higher frame rate.
How does the frame rates of the FHSS, S-FHSS and S-FHSS HS compare? Maybe that will make it all clearer

Status: offline 		This is straight from Futaba Japan, I hope this clears this up for everyone:


1.Output frame rate of sx signal by FHSS/S-FHSS
- 13.6ms : FHSS & S-FHSS(Normal mode)
> you can use all of analog/digital/bls sx.

- 6.8ms : S-FHSS(HS mode)
> you can use only digital/bls sx when in HS mode. (HS mode is only available at this time in the 4PL transmitter)

Note) All FHSS/S-FHSS rx is same, not only R2006GS.
R603GF/R2004GF support FHSS only, as you know.

Thank you very much for the clarification.  It has been helpful as I just purchased the 8J to use with my old Futaba servos as I am coming back to the hobby after a 15-year sabbatical.

I think the confusion with the High Speed frame rate (i.e. HS mode) comes from some reviews and other websites stating the 6.8ms number in their text.  For example if you see the links below. 

This add states that "In S-FHSS mode, the 6J’s frame rate is just 6.8ms, a response speed unmatched by any other 6-channel flight system...."
http://www.towerhobbies.com/products/futaba/futk6000m.html

Third party review says "The 8J also features the blisteringly fast frame rate of it's older sibling, the 6J, at 6.8ms. " at the end of the article.

Status: offline 		I went thru all this S-FHSS and FHSS a few months ago when I bought a new 8J, after retiring my 15 yr old Super 8. I was very confusing and I was getting different answers also, silent av8r is the most knowledgable and what he says is word in my book. The manual does not really explain it. The bottom line is the 2006 and 2008 rxs don't do high speed so it is really a non-issue. I'm not really sure why the FHSS setting is even on the 8J.

I am VERY happy with the 8J, have so far converted over about 12 of my planes with perfect results. And I am using every kind, size and type of servo without any problems. The overall price of the 8J is fantastic at $239 ($279 - $40 off coupon) with a extra free rx. I did my research on the 8J before buying, and checked out many other tx's by most other manf. The 8J gave me the most bang for the buck and just feels right when flying. 20 model memory, all standard features, backlit screen, no antenna which I really like, ect. I am also buying cheap Futaba 2006 rxs for $35 each shipped. Here's a few of my planes - ok, maybe not the F-18's.

Thanks but I suggest you prompt Tower to correct their adds unless the S-FHSS HS mode will come along later

It looks like you have a lot of time on the 8J. Are you using the R2006GS Rx on most?
Does range seem to be OK? I remember reading somewhere that the 6J and 8J Tx was much lower on power
than the FASST line of Txs.

This is a bit of misunderstanding on the part of the person who likes to spread this around. The 6J and 8J are full range systems and their power output is more than sufficient to ensure a solid link with your plane.

One of my main concerns when buying a new radio was the cost of the rx's, and reliability of course. I knew I was going to ultimately need about 15 rx's and was not going to pay $70+ each. The 8J originally came with the 2008 and free 2106 (short range) rx's. I ended up selling the 2106 short range rx since i don't have anything like that I fly, the 2006 and 2008 are both full range. I used the 2008 and found place that sold the 2006 rx's for $35 shipped and have ordered about 10 of those over the last 2 months or so. I have put many flights on the 10 or so planes so far with perfect results. And I have deliberately pushed them far out, high and low to check range, always been perfect. One of the features I like about the 8J, and there are many to like, is by default the failsafe is set up leave all control surfaces at neutral but cut the throttle to 20% if you lose connection, giving you quick notice. So far it has never gone to failsafe, but I like the idea that if something did happen I would get a warning. All of the failsafe functions are programmable. All in all the 8J is the best value for the money by far in my book, for many reasons.

Such is the case with the 2006 and 2008 receivers it seems, so no overheating of the servos.
I guess the FHSS option is so that the 6J and 8J Tx can operate with FHSS only receivers.

Status: offline 		Although the question about the 8j system working with all Futaba servos was already answered I wanted to confirm that it works flawlessly with my old Futaba S148.   Coming from a late 80's AM system, replacing it by the 8j feels like stepping out of a horse wagon and entering a brand new sports car.  Unplugged the old receiver, plugged the new one and everything worked out of the box.   The levers spring rates are just right and it feels like home (Futaba home).  The only thing I need to adjust is the throttle idle and cut point as my system was configured to use the analog throttle trim as cut-off.   No problem with that as you can setup a three-position switch for idle-down and cut-off.

The programming looks intimidating at first but some patience and a few minutes with the manual revealed the programming is straight forward.  The menus and navigation buttons are very intuitive.

As I discover all the features (some of them not named in reviews/advertisements), this system seems very underrated for its price point.

I will report later once I get a chance to fly with it but so far it looks like Futaba knocked it out of the park with this one.
