I don't have a Nikon, but it is So Very Nice when UHH's share unique fixes to knotty problems with each other.

While Pocket Wizards are outstanding triggers, offering unmatched range and if you use TTL excellent integration with your camera, less expensive alternatives do exist. I have been using Yongnuo triggers since 2011 with my old Sunpak 383 (and about another dozen or so variations of that flash) manually, with their least expensive trigger - the old RF602. It has been replaced with a transceiver version - the RF-603 II is only $30 - $32 for a pair on Amazon, eBay, B&H or Adorama. They have a line of sight range of 100m, and so far in use have yet to misfire (except for those times when I killed a battery). They are well-built and the company is great - initially the old triggers were a transmitter/receiver and did not have an on/off switch on the transmitter. If you forgot to remove the battery and the base of the transmitter came in contact with metal, it could short out. They replaced 2 of mine at no charge, and they subsequently but quietly modified the part to include an on/off switch. This is no longer an issue since they use a transceiver and it has an on/off switch. If your camera is supported, the transceiver can be used as a two-stage remote shutter release. I used the release to take this selfie, with a trigger in my left hand.

For anyone else here with the Part 107 certificate and hasn't renewed yet, I have awesome news.

Unlike the initial test which I must say was ridiculously over reaching with wing loading etc... to renew, you now go to the FAAST website, go through a roughly 2 hour tutorial, you can stop and start as much as you want, then take the final test which is all drone oriented, no in depth chart reading or airspace, more like accident reporting, who to contact for flight notifications, etc.

You do have to get 100% on the test, but it's not bad at all, and they do tell you what question you missed (I did miss one on the first try, misread the question), and the retake is the exact same test!

The best part, it's FREE!!!!

What they don't tell you, and it took me almost 2 weeks of emails and phone calls, but once you pass the test, you print off the test result and certificate, and keep it with your original, no new "ticket" is mailed to you.

I was dreading all this for nothing, especially going to a testing sight all over again, and studying all that chart reading, etc.

Again, this is only for renewal, the original part 107 is still all the same.

I'm passing on this info, because I haven't seen it on youtube, or any of the study sights, and the FAAST sight wasn't really that helpful either. It tells you about the class and test, but says nothing about not needing to send your results somewhere and waiting for a renewed "license" that will never come.

Any questions, just ask. I'm SOOO glad it's over, and it was so much easier than I had thought the second time around.
