I’ve used an old iPhone 6s+ for most of 2021 with SD and a yoke mount and more recently replaced with new iPad mini
Both work well and not overheated yet but I carry both, the iPhone as a backup as well as my iPhone I use as a phone for a 3rd backup plus paper charts but most will think that’s pure madness, I won’t disagree but I like to know I have options.
I’ve used a yoke mount, I fly PA28’s and being big I cannot find anywhere useful to mount them other than the yoke but I’m cheap….
I picked up an old garmin yoke mount on here from a fellow member which has a flat plate, this was covered in Velcro, with a big patch on the back of my iPad and iPhone case and it works like a dream!!
If it breaks I’ll likely get the RAM mount as I have the ram phone holder for my car and the sucker is pretty good.
Good points with yoke mount is that it won’t likely cover any important stuff and is a glance away.
I’ve even started to use Apple Pencil with SD and notepad side by side for atis, clearance which works pretty well also but I always have paper on knee board just in case
You don’t need it… but I also got a sky echo, which despite having a cell/gps iPad I always use the location from the skyecho which also gives possible traffic alerts, I found this is good piece of mind but TBH I’ve had just as many near by traffic show on sky echo as I have not so “eyes out the window” is still needed.
