is there a way to attach a lanyard to the spark rc. I use the phone mount for my iPhone and the only lanyard mounts I've seen so far block this or the USB port. Any other options?

I made this and uploaded it to thingiverse for sharing.
I designed it to fit the Mavic RC, but it should fit the sparks RC too.
Because I don’t have a RC for the spark I can’t test it.

I have the lanyard but never use it. Covers the screen so rather pointless.

Thanks for the replies. It's more to let the controller hang when I'm using guesture control. Rather than putting it down. I'm finding guesture is the best option for landing.

Yes something like this would work, its made for the Mavic controller however would also work with the Spark as the remote is the same dimension http://amzn.to/2u0gezD

Try using a bag strap.
It is stronger than lanyards, just connect it by attaching hook.
Or you can browse the internet for more option.

Landing? I just hover it to me and pick it out of the air.
