I took the leap and bought a PRO however I'm unsure if I'm going to keep it as being an earlier production unit it doesn't have the more powerful 1510 transmitter DJI licensed and began producing in October. I first called LA tech support as I was willing to ship it to them to swap it out but they said to return it to the retailer for an exchange. I drove back to the city and B&H actually opened half their stock searching for one with the new transmitter only to find they're all the older version. Looks like the down side to being one of the first to get stock. I can absolutely vouch for their sales practices and how they treat customers. Every case they opened searching for the FCC ID number I wanted was a unit that they'll have to sell as used as the seal was broken and although the serial numbers are all identified on the outside of the box the FCC ID isn't. I started cringing at every seal they cut. After considerable effort on their part we weren't successful. They're going to contact DJI and ask when they will receive units with the updated transmitter as they're uncomfortable with the situation ethically with the stock they have and have offered to allow me to exchange the one I left with when they are able to obtain the unit I seek. I would tell everyone here to watch for used PROs for sale on B&H's site and go for it they'll be a few and they'll more than likely be knew with nothing more than a cut seal and the older transmitter. I would also encourage everyone to patronize B&H as their commitment to exemplary customer service is rare in this day and age. Now I am in no way a DJI basher and truly think they are leading the industry which is much more difficult than following or worse copying and undercutting other manufacturers. Those who have issues are very vocal but if one digs deeper they're percentage of units with issues is far below all the major electronics manufacturers. To me an incredible fact considering they entertain warrantying a product the user can definitely have a large influence on its failure rate. All that said I have dealt with range issues which I come to find out can at least partially be attributed to the RC and Aircraft I own (an early model) and that even for the first model there are differences in transmitting power depending on which RC you came with it. That only really means they continued improving the product which is admirable and rarely will a manufacturer voluntarily inform and upgrade existing sold units. Now I purchase another DJI product and overlook that it wasn't just bad luck that caused me to spend a considerable of time and money modifying for range as I'm equally at fault as I never took them to task and sent it in (and waited for three months) for them to probably send it back with a newer RC. I'm not sure I agree with not offering repair parts for sale (especially with three month repair waits) but they're shaping the market and that's they're prerogative. I am however very surprised they aren't restricting the installation of the remaining 1410 transmitters to the end of the first model production and equipping all PRO and V2 models with the 1510 considering its a 5dbm difference at peak and that every 6dbm the effective achievable range is doubled and both are being sold at an increase in price. I feel this situation means there is room for improvement in manufacturing and sales practices. I know this company is growing faster than expected and will experience its issues but this type situation points to an issue of corporate culture that isn't versed in simple ethics which concerns me as even the delays in promised features could be explained away with not releasing products that aren't completely vetted. I'm attaching the actual test results commissioned by DJI and supplied to the FCC for licensing the transmitters in question so what I'm asserting isn't considered hearsay. I also created an album with much more data and information. I hope DJI doesn't continue down this road of corporate management as it would be unfortunate considering the potential they possess and I hope I'm able to get my PRO I desire with the 1510 transmitter.
