You can purchase everything you need for a crank-sensor here Ironhide.

Get the GV1 adapter wire aswell,there's lots of guys doing modifications to there set-up without using this adapter wire but I just purchased the wire. Great products that work flawlessly..Cheers!

I have sent three emails to Futaba over the last 10 days asking if and when we might see one. I think it is most unfortunate that they have not answered.
I have invested in 3 701's, simply because of the governor feature, but I do not want to use fan mounted magnets, and would prefer to use an oem product rather than converting a Spektrum sensor.
Even the current 701 adverts on this site state that a backplate sensor is available as an option.

As Ben said there is one scheduled to be released early this year.

However with several options available to get you using a backplate sensor now, I'm not sure why you would want to put off flying and simply change the to the OEM sensor once it's available as it would be a very simple swap.

It doesn't stop me flying, I'm perfectly happy to fly without a governor. It just feels like I've been hearing "there will be one soon" since the 701 was released, and I bought 3 precisely because I would like to start using a governor.
To use the Spektrum I have to invest in 3 spektrum sensor leads, 3 Spektrum to GV1 adapters and 3 upgraded brackets (as I understand the original bracket was not very sturdy), that is quite a lot of cash for a temporary measure when all I would really like to know is when the sensor will be available. Is that really too much to ask?

Wow, that seems like a whole bunch of unnecessary items.

If you want to use the Spektrum backplate sensor all you need is the sensor itself. No extra bracket, no diodes, no wiring harness.

You simply get a Futaba lead and splice it to the Spektrum lead while reversing both the pos/neg wires.

Nothing else is needed and this works perfectly.

I gave up waiting for the Futaba backplate sensor and tried to do as you suggested.

On a Futaba lead I have always understood that
black = -ve
red = +ve
white = signal

On Spektrum I assume
brown = -ve
red = +ve
orange = signal

Are you suggesting I swap the brown and the red on the Spektrum lead, or have I misunderstood?

Thanks

I didn't get a reply from Mike and I'm trying to avoid inserting a resistor unless I have to. The AlumaFx is always out of stock and I think the postage to me is $14? If you can get a reply I'd be really interested.
I did try swapping the +ve and -ve but I got a permanently high reading at the 701, I didn't think that was going to work, but I tried anyway.

I recently tried swapping the wires with the Specktrum sensor and got a constant 84%, never changed as I turned the motor over. Unfortunately the simple mod did not work for me. My guess is the resistor is a must.

The only way that test would work is if you were spinning the engine at a minimum of 20 rpm. The sensor will not "activate" until it sees a minimum of 20 RPM. So easiest way is to light it up and fly it. You will find out right away if the sensor is working or not

2nd, you can try without a pull-up resistor but not making any guarantees. I know what does work and have had no problem. BTW the AlumFx is available at some of the online shops.

If it is a simple mod of swapping a couple of wires I'd rather do that than introduce another length of cable which costs $25 + $14.50 shipping,(for a $2.30 stamp) + $17.50 customs and tax when it gets here. Thats nearly $60 each for 3 governors.

True but if you do it yourself it is much cheaper. The ones I have done so far might have cost me 50 to 75 cents. If you don't want to introduce another cable you can do the modification right in the existing cable from the sensor. I just do the adapter in case I have to replace the sensor or adapter I can just replace the one item.

But of course try the swap. Worst it will do is not work and maybe it will. I just know how the original Futaba sensor worked and modified the Spektrum to work in the same manner

Just to add to my first post. I did fly the heli and the governor did not engage with only swapping the wires.
