iFly GPS Forum

Jim: I flew with 7.6.14 on my 720 and a SkyGuardTWX for 1.2 hours today and everything worked FLAWLESSLY. I did a lot of maneuvering, changed map modes a lot, changed flight plans/destinations, a lot of screen touches, and never had a glitch of any kind. I did see traffic (the blinking blue tringle stood out fine in Weather mode, but I did not check to see the traffic triangle with a sectional or TAC background), but I never had a ghost warning nor did I ever notice a ghost following me - probably a function of ADSB-OUT anyway. I am loving the 720 with the SkyGuard TWX. You have done a very good job of integrating these two units. I am looking forward to seeing the display of TFRs from the ADSB data stream in the future, too. On my next flight I plan to actually contact ATC, get a discrete squawk code, and see how well the 720-SkyGuardTWX plays "in the system." Thank you very much, Walter, for all the continuous improvement you have engineered into the iFlys. It just works so well and is so easy to use and is chock full of useful features. ====Ralph

By the way, someone else reported hearing a transceiver tranmitter ping from the SkyGuard TWX. I am not hearing anything like this at all. It must be a function of where his gear is located in the airplane or perhaps how his audio is grounded.

Tim: I did not try to mount my SkyGuard TWX transceiver back on the hat shelf because I used a metallized foil insulation around the cabin when I restored the aircraft. I could put it inside the fabric fuselage behind the baggage compartment if the 4-ft transmitter cable will reach, but have not tried that yet. I may experiment with other arrangements, like moving the transmitter antenna to a rear window, but right now everything works so well I am inclined to leave it "as is" for the time being.
I currently have my unit on the glareshield. I find it unobtrusive there. I have the transmitter antenna mounted over on the right side - it has a magnetic base mount (or velcro), but since all my material is aluminum or fiberglass I made a small teardrop tab out of galvanized steel which then holds the magnetic base securely. The GPS puck sits smack dab in the center, up against the windshield, completely out of sight. Then the main unit is over on the left side behind the wet compass. This places the UAT and ES antennae about 28 inches away from the transmitter antenna; 18" minimum is recommended. I will take some photos and upload them next time I go to the hanger.
I have not wired the 12v into the avionics bus yet, but that will come later when I have settled on final placement of the hardware. It just needs a 5 amp circuit breaker. I have powered up the SkyGuard first then the 720, and vice-versa, and it does not seem to make any difference - they play very well together automatically. Right now my 720 powers up with the avionics master switch, then I plug the SkyGuard TWX into the cigarette lighter socket and everything handshakes and establishes the connection automaticallly. ====Ralph
