I would like to buy the following things, all at once if possible or sourced separately. Will be purchasing first week of April.

APM 2.6 or APM Mini 3.1 Flight Controller
MinimOSD extension
434mhz telemetry module
ublox GPS with compass
APM power module

Cannot buy from any place that would take more than a week to deliver. Don't mind buying from users, but would need a fresh piece

I have this but more ( better GPS module OSD plus other stuff too ). And regarding a 'Fresh Piece' IDK what you mean by that but yea mine is fully functional

Oh by fresh I mean new parts, this is my first investment so kinda want it mint condition
However it is good to know, because I might build one more for a friend

Please check following links.

Maybe it will help you.

I would have gone for http://www.rcproduct.in/multi-rotor-flight-controller/51-ardupilot-mega-26-external-compass-wublox-neo-6m-side-pin-.html but seems to be out of stock now! Anything above 9k is not a good deal for me you see

Actually that is a older version and only APM and GPS.

The Above links for APM 2.7 which is new version of APM and that is a combo set.

APM 2.7 is not an official version and there isn't any software upgrades that is exclusive to the "HK 2.7". The HK 2.7 board you have is a modded APM 2.6 from HobbyKing which is not really official. Of course it might be a better board but HK 2.7 isn't APM 2.7. I want the APM 2.6 specifically for modifying the firmware and interface.

You can modify the firmware same as any other apm. The 2.7 merely refers to some minor hardware changes like some capacitor or diode added

Yes, but why would I pay 3-4k more for "some capacitor or diode added"? I have multiple offers that gets me the same deal with 2.6 and way under 12k.

Ive got Mini APM 2.6, No-GPS Compass model included, comes with 3dr radio, power module, Minim OSD
Loaded with arduplane, received few days ago from china, needs just a ublox module to complete.

let me know if you need it, expecting 9K-free shipping.
Reason for selling:bought it for FPV plane, it took too late to arrive that i lost faith and made a deal to sell my FPV equipments, so not needing this now,  planning to sell it to raise fund for some nitro stuffs.
