I would like to have a plane that allows me to do mapping. I am looking for a model that can carry a payload of about 2kg I already have the pixhawks with the downlink, Futaba radio 14sg, sony nex-7 with 16mm pancake lens. 3S, 4S and 6S 5000mah battery. I would like to fly around 40 minutes. I want it to be disassembled and easily transported in a car.

I looked at some models like Penguin and X6 Skywalker FPV wing but the payload is to low,

For now, the 2014 model skywalker 1800mm and Latest Version Black skywalker X8 Flying Wing seems  a good choice.

What are your suggestions and advice about models for mapping?

Both of planes have good gliding performance and power efficiency. However Talon has better stability in term of rolling movement, it could be a good point for video recording. I did not record any good quality video, I just used fpv to help me navigating the plane; yeah... actually just watching all of flight parameters displayed by OSD and switching to RTL when battery is low.

With my setup (830 kv motor, 13x8 prop, 2 x 4S 5000 mAH), my best flight record with Talon is only at 74 minutes. The average is around 55 minutes. It is hard to get long flight on strong wind day.  I fly most on windy days, usually at 40-45 km/h - and still get very good pictures for mapping. Maybe sometimes I fly at  more than 50 km/h wind speed; I am not sure cause I did not measure it every time I fly. I am thinking to use lower kv motor with bigger prop to get a longer flight. However, it will need motor mount modification on Talon or the propeller will hit ground and break easily.  

My opinion (and it is only that). Belly landing a $$$$$ Sony nex/lens in a foam aircraft is something to think twice about.

This was for local mapping company - nex fully enclosed in fuselage with landing gear and automatic lens protector for take off/landing.

Like I say others may feel this is overkill.

put me in the queue for composite Talons, love mine as well.

Put me also in the queue for the composite one and I will take 3.

 

Does the Talon (EPO) have room for a straight downward facing camera mounted in landscape orientation, not portrait. Something like a Canon S100 (about 10cm wide)

Yes you can. It has a plenty space, even for slightly larger camera in a landscape orientation.

I like to know how people ruggedize and re-enforce Talon EPO airframe. Could you share the pictures?

Put me in the queue as well please.

What airframe is that?

We will be releasing a VERY affordable DIY kit for our new RF-70. If you message me privately I can send you complete details.

RF-70 BUILD IT YOURSELF KIT (anticipated package content, not yet finalized) : 
 
.            RF-70 : 1 left wing, 1 right wing, 1 center fuselage. All foam is 2.0+ density
.            Proper brushless motor and propeller combo
.            Electronic Speed control
.            Necessary servo cables 
.            Two matching metal gear servos
.            Elevon control horns
.            Transmitter and receiver
.            Pixhawk with a hyperlink for downloading proper preset parameters
.            Bungee Cord launch system (not rail launched)
.            Complete DIY Kit Build Video
.            Links to recommend camera sensors including NIR for precision agriculture (not currently suggesting Tetracam, Canon S100, or SX230/260. There is a better Canon camera).
 
Also:
.         2 custom made carbon fiber spars with glass slip tub sockets
.         FG rods for fuse and wing sparring
.         Coroplast verticals
.         Coroplast winglets
.         Coroplast payload bay covers (2 saddle bay covers, and 2 covers for the center fuselage)
.         Custom T6 CNC aluminum motor mount with 440 screws and lock nuts
.         2 2" custom balsa elevons
.         8 Delrin wing joiner clips with 4 tension 0-rings
.         12 aluminum screw hubs with 12 match black nylon thumb screws (hold the payload covers down)

you can also choose to set up a skywalker x5 or a FX79 (much better design but more expensive)

I reinforce the talon surfaces using glass fiber cloth and wood glue like this:
