Hi Shawn.
I talked to Jeff a few weeks ago at Oshkosh about replacing one or both of our screens in our TWTT Sportsman and he said he was currently upgrading the same panel and would check and confirm for me whether a 5400 would fit into the right side panel. Our Australian ADSB requirement comes into force on January 1, 2017 so a panel upgrade of some sort is imminent in the coming year.
At present I have a 4500 ON THE PILOT's side and a 3400 and GTX327 TX on the copilot's side which was the standard "delux IFR" TWTT panel in 2008. I am now considering your Dynon TX (behind panel) and also replacing my pilot side 4500 with a 5400 to operate the TX. I am therefore also interested in replacing the copilot side 3400 with another 5400 if it will fit where the 3400 and GTX327 now currently fit.
Can you follow up with Jeff and advise whether there is enough space in the copilot side TWTT sportsman aluminium panel insert to accept a 5400? My intent would be to enlarge the current two holes in the aluminium insert into one to accept the 5400. I am not however interested in making major changes to the composite base panel.
Regards, Kevin
