OK, so I ordered a mount for the mavic but they sent the wrong one. I could return it but thought I would offer it here first - They cost £75 new. I’ll take £50 + postage.
This has been unused, though I have taken it out of the box.
I’m technically inept - if you are interested i can email you photos but Spike will vouch that I’m a genuine bloke.
Cheers
Nigel
