Yes... are there lucky people in the India who got this usguely most hot item in Hong kong ? I have been waiting for the stock to arrive for so long.

There are people reporting that the Rx works fine with Futaba T7C and 6EX transmitters.

There are other people on e-bay having the stock. but they are selling at much higher price of $59, which is a deal breaker as the OEM 6 Channel FASST Rx is already sells at same price.

Interesting to see it uses a FPGA rather than a microcontroller. That means it might never become as cheap as the other clones. On the flip side, the latency should be good if designed right.

Hmm... FPGAs in a RX is quite interesting. As Rotor said there are not cheap devices. May be down the line Futaba may have plans to make them into cheap ASICs. Who know, by that time, the chinese would have clones with COB chips...;-)

I should get mine (3 pieces) tomorrow.  Forgot to follow it up with the post office/customs after I got back. 

Will post details here.

Got them. Will post reviews after testing on the field this Friday.  They were just sitting at the post-office since the 19th !

looks cool. is it a full range one ??

The range claimed is 1.5km.  But there are some "interesting" notes on the product page itself.

1.  Disable failsafe on transmitter, otherwise you will experience servo jitter.  Failsafe is done differently on these.

2.  Great for small planes, helis, parkflyers or even medium sized sport planes.  So I would not put it on anything beyond 40 size.  Preferably limit it to park flyer electrics and small helis.

Thanks Anwar Gi. I saw the product page after my post. Please keep us updated, I want to by few for my foamy ones. Now I am using Assan on a 6 Channel JR for the foamy planes, But I have to carry both TX to field. If this one works I can use one TX. As indicated in RC model Reviews "current-draw of the TFR8 was around 30% higher than the Futaba R608FS". So I am not sure if its ok  for small electric ones ?? Please post your review.

Tested the receiver on the field, on the HK 450 Pro test and abuse bird

1. Disabled failsafe for the model.
2. The binding was very quick, like in a second.  Hold the button down, and connect power to the receiver.  The negative pins of servo connections are closer to the board.
3. Set failsafe by holding the button down for one second on the receiver itself, with the throttle stick at zero position.

Did not notice any difference in the flight compared to the original Futaba receiver.  I flew as far/high as I could take a 450 class heli. 

The only thing I felt wishing for was a better casing the receiver, especially while mounting it. More than anything else, it felt a bit weird working with a receiver seeings its innards !

@ anwar
Have you tested receiver range...?

Like I said, I took the heli as high as I could.  Will continue testing with slightly bigger planes which can be taken even higher. 

I can say with conviction that range would not be an issue for small electrics.  As always, make sure your two antennas (the exposed tip parts) are setup to be perpendicular to each other.

looks promising 

Guys, I was just wondering, if this is a full range reciever then what is the problen in using it in medium sized planes. I mean maybe a 90 engine. If it were to create problems in bigger planes then neither should it work in small planes. What say all.

1.  The manufacturer does not endorse it.

2.  Why doesn't the manufacturer endorse it, especially being an "8" channel one which would better suit a bigger plane with more servos ? This is where we have to suspect things like whether the receiver is designed to handle say 6 or 7 current hungry full size digital servos (or something like that... I am just speculating).

Oh.. one thing I noticed was that the antennas were capable of rotating at their base (where they are attached to the PCB).  I can't imagine why they did that, a direct soldered connection would have been simpler and more reliable ?

The receiver really has nothing to do with the type of servos used. The only problem could be very small tracks on the PCB for the power supply to the servos. But I cannot imagine ANY, half decent, manufacturer goofing up on this aspect as there is no "rocket science" involved.

Of course. Whether it is PCB tracks or quality of materials used (both affecting current carrying capacity) or just their own confidence in testing (and related warranty issues), this is one of the aspects of why a manufacturer would intentionally exclude themselves from more widespread use on a receiver that is claimed (and proven) to be full range.

Once the receiver is full range, then the big difference I can see between small (to medium) and bigger planes is the number and size of servos.  Hence my suspicion that it could be current capability related.

If current draw is the only issue, it would be very simple to power the servos separately and only take the control signal from the Rx.

I am sure we will see some of that in the future by more adventurous folks   Waiting out on RCU, RCG etc for the same.

People who put Assan stuff on their gassers during its initial days for testing, will not lie low on things like these too.  If they work fine, the word will get out and we may see these being used in all sorts of bigger planes too !  I hope that happens. 

Or even better, I hope they come up with one that is fully designed and tested for bigger planes too !

Guys any more testing done on the Orange futaba compatible Rx? I have a SPAD extra ready with an ASP 52 engine, for testing if there's anyone willing to donate a Rx.    .

Back in stock, with a proper case :

For people like me who got the first batch with simple plastic shrink wrap on the receiver, there is a custom case that can now be ordered separately.  It seems to prevent the antennas from rotating around, which was one of the issues noted in this thread.

Hi friends,I'm asking this question on behalf of my friend..Any body tried the Futaba compatible Orange receiver? how abt the review of tat product? can it be used with 6EX 2.4GHz tx? Thank you..

Hi Krish....

I have been using the orange recievers with the 6ex from a long time and basis the same here are my observations :

1. No range difference
2. have flown them on planes upto .90 size no hassles whatsoever
3. remember to tame the reciever to the standard servo mode
4. remember to switch off failsafe

Go ahead and use them without fear .. I have tested them to all limits !!!
