can you get replacements bumpers for the phone holders of the controller?  
When I first got my Mavic I was tired of always having to remove my iPhone from its case in order for it to fit into the R/C arms.
I modified the arm inserts to accept the phone in the case. IE trimmed the rubber parts of the inserts. My question is can I buy replacements?
I now have a external iphone/iPad holder and need the original inserts to make it fit properly.
Any help is appreciated.
Looked all over the dji website and cannot find any replacements.
Also need a set for my spark controller.

Hey Skiman, could you upload some pictures for the double check? Thanks in advance!

Here are the pics you requested. The spark has the same type of inserts.
