Here we go again guys.. I'm really p*ssed that this is happening yet again -
By chance have you used the same props on all 3 of the birds you've had? If the props aren't balanced good that can cause excessive vibration and may result in the cracking around the motor screws. I would check the balance of the props with a balancer. Another way to tell is hover your bird about a foot over your head and look for any vibration of the landing gear. Of course be very careful and do it on a calm day careful not to give yourself a haircut lol. Just a thought. So far I've been lucky, running dji carbon reinforced props that have been checked for proper balance on my p3 pro, have about 60 flights under my belt and have logged over 400,000 ft of travel without any issues. It's windy in my area and while I am careful my bird has been flown pretty hard.
This is my 3rd phantom 3 standard actually, the very first one cracked under one of the motor arms screws (hairline crack appeared after my FIRST gentle flight). I returned it and got a refund then purchased one from another well known dealer.
Second one I purchased from the new dealer arrived USED and very dusty, plastic seals were missing from the props - anyway they replaced it with a new one up on return. The second one all seemed fine, everything looked and operated as it should.
(All in all this is my 3rd p3 standard), I have only had this new one 2 weeks, the weather is still bad here in the UK, so I have only had the chance to fly it 4 times.. battery has not been below 40% and has only been charged 3 times (as seen in the app).
Funnily enough after my past experience, I was worried that the cracks could appear again, so I have been checking for hairline cracks very often.
Tonight, I decided to check the arms and screws for any cracks as I was gonna take it for another flight on Friday, and guess what... here we go again, 2 hairline cracks under one of the motor screws.
I don't know whether to ignore it and see if they get worse or contact my dealer RC GEEKS and see what they say? normally their customer service is great. But I don't know what to do..
I can't put my self through all this again lol .. (I'm sure some of you may understand)
Thoughts please? what do you think I should do?
Should I just give it up as a bad job and move on?
Thanks guys, and sorry for the long post.
