I have a new Pixhawk coming in the mail with a new NEO-M8N GPS. Is it plug and play with the latest Airplane and multirotor firmware?
I will be first using it on a Quad but later this winter I will be putting it in my airplane. I have been reading and there is a lot of conflicting information about these new GPS modules. I found some information on possible changes in the code for Europe but I live in the US?
It should arrive in a week or so and I was planning on loading 3.2.1 Quad firmware. What can I expect – what should I be looking for to know if it’s working ok or not? I am not an expert on programming and was hoping it was just a plug and plan combo.

I have noticed that some decrease the EKF_VEL_DELAY and EKF_POS_DELAY because the 8 series have less lag than older series. Has anyone experimented with this to find the optimal value?

See I bought the one from goodluckbuy as well and I wasn't getting good flight performance on LOITER and RTL so I decided to open that module even though I was getting hdop 1.2. I found that when they closed the housing they had pinched a yellow wire which is DCT SCL wire for the Honeywell DCT they ise forget the exact name at the moment. I highly recommend opening that housing to see what the inside looks like. 4 1mm screws... piece of mind. The board was excellent and soldering good but an assembly issue.
nobody can really say what you will get, the GPS may be ok, but the "clones" (should be named partial-clones) are missing power redundancy chip, have no IO buffer chips , or only one, when real Pixhawk have 4 , and are completely missing all bigger capacitors, and >30 resistors, >10 smaller capacitors - I did not take time to fully analyze it yet..
I have also read that some are good, and some not, so maybe I'm just lucky.
Immediately ordered two more of the same type, but have not tried them yet.

Thanks, that’s very encouraging news.
What version of firmware are you using? Is it a multirotor or airplane?

I used to run a homemade breakout with a Ublox Max-7, and a Tallysman active antenna, but so far the cheapie N8M gives better results. I live in Northern Europe, so I guess I make good use of the Glonass satellites.
