Great mod. I have the Tarot retracts that came with the 650 Sport. So they are built a little different. I haven't looked at the guts yet but hopefully they work similar to these in that they use the 2 stop switches. I need a little more angle on my retracts and this looks like the trick to do it. I'll report back once I'm done.
Sorry I just don't have the time to make them for others. I haven't even found the time to finish setting my copter up. I hope you give it a try or even find someone to give you a hand it's not that hard just a little intimidating. If you have any questions just let me know..
Excellent way to add weight and destroy your gimbal and camera when these fail in flight :) (either that or risk severing your jugular trying to catch your huge hex by hand!). In all fairness though, this does look very, very sexy indeed when working - almost worth the cost of replacing all that stuff alone!
