My used P4 standard has developed a slight vertical twitch that comes and goes.
I read about it possibly being the cable.
While examining the bird closely I alco found a small crack in the upper shell.
After researching I suspected a pitch motor and I thought I would send it to Dr Drone here in Canada for repair.


I was shocked at what they quoted and the number of parts they said I needed.
I am wondering if this is just a shotgun approach to repair.
They boast that they test every facet of operation and guarantee the repair.
I guess I'm just looking for advice on how to proceed.
This has been a great drone and aside from the camera twitch is flys great in all modes with Litchi, DJI app and NLD app.

I hope someone can give me some advice

They sent me this repair estimate Quoted below
Just for reference

The upper twitch was happily fixed on my P4, by replacing the roll motor. The price varies a lot from suppliers. I wanted mine quickly to get the fall colors. It was hard to find someone not from China, which took forever to get. I finally got one from someone from California and received it in 3 days. Roll motors can range from $20 US upward. Changing out roll motors is very easy and can be done in 15 to 30 minutes. Take cover off, release ribbon cables and a few more screws. The motor will lift out. You Tube is your friend.

2nd Rootman. Easy repair I’ve done a few times. Available on eBay and sometimes Amazon. Best price is Walmart $19.95 but usually out of stock 🙁. Good luck, have fun
