Iphone case compatible with Ruko f11 pro

[Sklwater2]

Embarrassingly new newbie. Just received gift of ruko f11 pro. I have a pretty narrow case on my iPhone 6, and it will not secure in the transmitter. Rather not just keep pulling off the case, if someone can recommend a particular one that the transmitter will hold snugly.  

Thanks in advance,

Alan

The phone holder on the remote can expand to hold larger phones. It's just a bit hard to pull it out.

I appreciate the response. Yes, it expands enough, but it pretty much just sits on the case, phone always falls out while flying drone. Hate to keep taking whole case off phone every time. I do have a very narrow case, now. Thnx.
