MrC said:Interesting. So the motor winding wire has a clear coating on it which insulates it and if not properly removed around the soldering end could make for a bad connection at the solder point. And is resistant to the heat of the iron. Have you tried to remove with acetone?
Could it be this simple? I hope so.
So, do you think the esc's are ok?

This speculation is not in line with the factory soldering shown on the numerous esc pictures posted on this forum.burlbark said:I found an issue guys. This may be the cause of so much of the grief.
The high temperature windings on the new motors does not burn off by soldering alone. I needed to use map gas and get the motor power leads glowing orange to remove the insulation. I had to physically scrape the copper wire after heating it to 2000 degrees.
If DJI is simply clipping these motor leads and soldering them down without removing the clear magnetic wire insulation they are causing an area of high resistance and results in massive heat buildup at the solder point. The only contact point would be the clipped power lead end.
This may be the reason why we have seen the broken leads at the fets and why the flexible wire fix alleviated this problem for customers.

Dear Hani,
Thank you for contacting DJI North America.
We would be happy to assist you.
Regarding the issue that you are describing, we have not collected enough data to be able to offer an assessment. While we are aware of a handful of complaints made by users on various forums, our engineers have not had to issue repairs for this problem on a large enough scale to consider it a widespread issue, as we certainly have more users that are flying their units without experiencing trouble than we have users sending units to us for repair.
However, you can rest assured that if their is a discernible defect found with any Phantom units, our Repair Team will be available to correct any damaged units.
As of now, we are taking all Phantom issues on a case by case basis and will be happy to assist you if you experience any technical difficulties.
If you require any further assistance, you may contact us Monday-Friday, 9:00am-5:00pm PST at 818-235-0789.

jasonb777 said:Hey burlbark I sent back my vision plus V3.0 last week, and this week or next week I will hunt down a vision plus with the V2.1 escs. I was just wondering with the new v2.1 escs if you still recommend changing the wire to a larger gauge and if so what method are you using? Are you sleeving the wire and using silver solder after you cut the winding an inch from the motor? Also what temp. is the insulation of the shielding rated at that you recommend? A brief description would be greatly appreciated.

I'm considering investing in a P2V+V3, for a few potential business ideas I came up with. I've been researching the competitions models and found that actually the V3 would best suit my needs for the project I'm wanting to launch.
But first a bit about my background. I've been in corporate aviation for over 20 years and I'm currently an airworthiness inspector, A&P - I/A for a corporate jet company in Savannah GA. I'm well aware of the quality process and the overwhelming hurdles associated in mass production. However, I'm completely at a loss for words when it comes to DJI's unwillingness it seems coming strictly from an 'outside looking in' prospective. From what I've read thus far DJI refuses to take ownership in their oversight of the reported problems w/ the wire routing over the ECM heat sinks, the ventilation of their broadband circuit boards, and I've seen some reports about incorrectly terminated coax connectors causing potential loss or damage to their units. What I've also failed to see, based on my short research, which I also find alarming, is any statements from any dealers voicing concerns. In my business, if I unearthed a deficiency of this nature, a few phone calls would trigger a full production research, customers notification, and the effected units would be swiftly grounded by the end of that day, until a repair matrix was established and carried out to satisfactorily address each and every unit. Granted when lives are on the line these necessary steps are mandated to keep air travel a safe place industry wide. But I find it astonishing DJI has decided to remain silent and not face these quality issues and rise to the occasion. I'm fortunate to say that the company I work for, spends millions a year and strives diligently, to remain at the top of the industry in regards to customer service and have established a customer satisfaction rating that the competitors all fight to top. That being said, with the release of GoPros intentions of releasing a version of a hi-def quadcopter, one would think DJI would rise to this occasion to assert itself as an industry leader in BOTH their products and service after the sale...
But so much for my rant... It's great to be on this site, Have any of you considered voicing your customer service concerns on YouTube? I posted mine here: https://www.youtube.com/watch?v=e3E4CPPz32c
I really hate the fact of setting my projects to the side until this blows over, would any of you know of a reputable dealer that might be able to check for the appropriate updated mods prior to shipping them out?
Kind regards,
Chopper
Justin Davis from DroneCamp is a very honorable person and has great knowledge on these birds. Howwever, I doubt even he will start opening up brand new V3 Quads to check for all the updates. Try him. He's stand up guy!
