I don't know, Trou. Sorry about that. It's not a very satisfactory answer, I realize, but I'd try it -- all depends on whether you can set the angle limits in the Radian software. Andy.
The gyro only has reference to the ground, not to the absolute position of the pan relative to the copter. So, no, you can't limit it with the radian. It would be really nice if they would implement Majestic mode into the Radian, but it would require some type of encoder on the pan pulley, which is what it looks like is happening on the MoVi.
