I see no problem with PCM frequncies between 8 and 16kHz and max ~4000Hz on full trottle.

But you can decouple your TM1000 with an optocoupler.
Then need you a extra voltage source for the TM1000 lost the RX voltage but antenna information is still avaible.

Regarding my question about connecting Gps to Spektrum rpm port i have found the problem, is my mistake, the formula is round 32768, not 32754, going to the lake testing the results.

I am now installing the air speed indicator on my hangar P51 mustang sport (with Spektrum DX7s). I m going to drill a whole in the wing's leading edge and insert the Pitot tube. Can anyone advise me on how should I glue it to the wing? Epoxy or silicon?

I noticed some have used Robart Quick Disconnect to facilitate connecting/disconnecting of air tubing when putting the wings on or off. I have another idea - i wonder if I can make it work: install the sensor in the wing, very close to the tube (so then I'll have the air line very short) and run an X_BUS extension through the wing to the TM1000 in the fuselage. This way all I'll have to connect/disconnect will be an electrical cable. Problem is that I can't find a proper male/female XBUS extension cable. Any thoughts?

Silicone might be better, give it a little shock absorbing for those in-hangar bumps. Get as much of the tube as possible out in front as far as you can. They work much better the farther in front you get it. The value in the manual is the bare minimum. I try to get the crotch of the Y right against the inside of the LE.

The connectors are not rated for lots of insertions. If you go that route make it so you can replace the wire easily (assuming you take the wing off to go home). We have several extensions - choose the one that's right for you.

I use the Robart Quick Connects. Works very well.

Thank you for your replies, Andy and Harry.

Ok so I will be using silicone (the one used for sealing kitchen counter tops) to "glue" the pitot tube to the wing (after drilling a hole, of course). I'll try to stick it out as much as possible.

I am gonna give up on my idea of using electric cable extension +connector and I will go with Harry's suggestion of using quick connects. But all that I could find was "Robart Quick Disconnect" - see photo. I assume there are the same thing. Also Robart 169B air line (photo also attached).

Just trying to get everything right without breaking anything

One more question, please, Andy: what is the latest software revision (firmware) for DX7s? Mine seems to be at v 1.00.

Thank you again and happy flying!

Yes, you got it right. I used the silicone supplied from the pitot tube to the connectors and then the Robart line the rest of the way. Depending on how big your wing is, you may have enough silicone to do the job. I was short about 1 1/2'. Remember to get the pitot out far enough to get it out of the prop wash.

Any news on the GPS module?
Will it be availiable in June as planned?

Looking to buy 3-4 of them

I want the vario module. I'm liking the altimeter module but I seem to be having range issues at times.

I'll pick up a GPS module when they are available.

Anyone?

Looks like it was pushed out for yet another 30 days.

Apparently not in the near future as there isn't any new firmware updates available for the DX8 that will support the GPS sensor. Also, Spektrumrc.com shows it as "Due early July, 2012".

It's enabled in the DX18...

I'm trying to read between the lines ... are you indicating the GPS sensor will only be available on the DX18; or are we going to be able to use it with the DX8 after firmware updates? If so, when can we expect the updates?

Thanks.

I think we can probably expect them when they are released.
