I also have (and suggest) a RAM mount. I fly both yoke (C182) and stick (DA40) airplanes, so I bought the parts to do both yoke mount and suction cup mount. Here's what I've got:
1)
Yoke Clamp Base with 1" Rubber Ball and 1/4-20" Tap for Camera or Video
2)
3.25" Diameter Suction Cup Twist Lock Base with 1" Ball
3)
Double 1" Ball Adapter
4)
"B" (Medium) Arm
5)
"A" (Short) Arm
6)
iPad Cradle
7) Two 2.5"
2.5" Round Base with the AMPs Hole Pattern & 1" Ball
Obviously I'm not using the suction cup and the yoke mount at the same time, but all the rest of the parts are in use. Here's a top view of it mounted in the DA40 which shows the double-ball connector and both arms:
Having two arms and the double-ball connector allows for a lot more positioning flexibility, so it works in both the DA40 and the yoked airplanes as well as my car.
In the 182, I use the yoke clamp, then run one arm from that towards me, and then the ball and the second arm allow for it to "bend" down over the front of the yoke so that the iPad is centered better.
Here's some pictures of it in the airplane:
My only negative would be the GPS will only mount on the bottom with this mount. Jury is out as to weather it will recieve.
I actually mount mine upside down. The iPad really doesn't care, it'll rotate the screen around, the only difference is that the home button will be on top.
Does the RAM system require you to extract your iPad2 from any carrying case you might have?
I have the Otterbox Defender case (and like it). Can RAM (or other system) permit mounting without removing from the case?
Was thinking about the suction cup system. So I could mount that in the "zone" where the left glareshield meets the side windscreen on the Warrior I'm renting. Anyone have experience with something like this?
See above.
As for the OtterBox, RAM was going to have a specific cradle for the OtterBox, but there's nothing on their site about that any more. However, all you need to do is get
this cradle instead of the standard iPad cradle I linked to above.
