Following "one project each year" rule , i will start to build a platform able to do photomapping. With the first trial i was not so happy so i decided to give another try (http://www.rcgroups.com/forums/showthread.php?t=1610263).

Here we go :

1. airplane - Skywalker X5: http://www.hobbyking.com/hobbyking/s...ng_1180mm.html

2. airplane electronics :
- motor: http://www.hobbyking.com/hobbyking/s...dProduct=16230
- ESC : http://www.hobbyking.com/hobbyking/s...idProduct=2165
- propeller: http://www.hobbyking.com/hobbyking/s...dProduct=13169
- propeller 2: http://www.hobbyking.com/hobbyking/s...idProduct=5438
-(2x) servo: http://www.hobbyking.com/hobbyking/s...dProduct=17322
- radio transmitter : Futaba T9CAP
- receiver/transmitter - Frsky
- battery (2x) Lipo 3s 2200 mAh

3. Flight controller- here there are the options to analyse:
- Gluonpilot v2 :http://gluonpilot.com/shop/products/...64dc1aa9e8fec1
- UavDevBoard5 :
- ArsovtechUAV3 :http://arsovtech.com/?page_id=164
- APM 2.5 : http://store.3drobotics.com/products/apm-2-5-kit


4. Photo camera - now i have a Canon A480, it will be the trial camera until i will have all the sistem working.After this i want to switch to a Canon SX200 / 210 / 220 / 230 .


OBSERVATIONS:
3. Regarding the controller it is quite a difficult decision to make, here are the points that i will take into consideration for using the controller:

- price ;

- work involved to make it work, parameter tunning;

- dimensions;

-groundstation-telemetry (i want to know where is the airplane during a photomapping mission / upload, modify a mission live);

- possibility to add an OSD;

- controller capability to maintain altitude, to follow tracks, waypoints...

Until now i have the wing , the electronics are on the way and i must decide about the controller in 2 weeks time. If all the things go well at the beginning of august i will start to build the wing.

Any ideea , sugestion regarding the build log is appreciated.

So after a loooooong time i've decided to begin another project.

The "guilty" ones for taking this decision are:

Chris Anderson - with the Trust Time Trial (T3) competion he spread the UAV virus http://diydrones.com/profiles/blogs/...-landing-round

Pete Hollands/ Riccardo Kuebler / Phil Giacalone / William Premerlani /UDB community for demonstrating what is UavDevBoard capable to do.

The wiki page for UDB is here:
http://code.google.com/p/gentlenav/

The discutions about the UDB4 are here :
https://groups.google.com/forum/?fro...um/uavdevboard

On the wiki page you find a lot of informations, this topic is supposed to remind me what i've done during the project(all the steps/setups), maybe someone can find the topic usefull.


The main purpose of this project is to have an UAV capable to do Auto takeoff/land , make autonomus missions and to be used for FPV.

What i will use :

1. Wing Tiger V2 - electric trainer

http://www.bananahobby.com/1651.html


2. Futaba T9CAP + FRSKY two way transmitter module http://www.frsky-rc.com/ShowProducts.asp?id=34 and receiver

http://www.frsky-rc.com/ShowProducts.asp?id=89 .

The receiver is capable to output RSSI (PWM) and CPPM output directly from it's pins,no soldering required.

3.UavDevBoard 4 http://www.sparkfun.com/products/11115

4.MediaTek MT3329 GPS http://store.diydrones.com/MediaTek_.../mt3329-02.htm

5.Openlog http://www.sparkfun.com/products/9530

6.Nick's OSD http://arsovtech.com/?p=1232

7.Magnetometer http://store.diydrones.com/HMC5843_T...hmc5843-01.htm

8. Clone PicKit 3 from ebay : http://www.ebay.co.uk/sch/i.html?_fr...All-Categories

9.FPV camera http://www.tmart.com/MC495A-520TVL-M...k_p122180.html

10. 5,8 ghz receiver http://fpvhobby.com/33-4ghz-8-ch-a-v-receiver.html and mini transmitter http://fpvhobby.com/93-200mw-58ghz-a-v-transmitter.html

11. A Canon A480 with CHDK installed (http://chdk.wikia.com/wiki/CHDK_in_Brief) for photomapping.

I have the majority of the things, it's only missing the Pickit and the fpv camera.

That's it for now.

Well after a flight break and before another short break I want to build my future platform for DOSD V2 version.

The plane(it is a used one) will be equipped with :

1. DOSD V2

http://www.rcgroups.com/forums/showthread.php?t=1211816

2. Dragon Lab Current Sensor

3. Arduimu

http://www.sparkfun.com/commerce/pro...oducts_id=9956

4.Pressure sensor

http://www.sparkfun.com/commerce/pro...oducts_id=9694

5. Gps module

(For buying gps module,current sensor, Dosd V2 you should talk with John-- jmstech1@gmail.com )


Questions:

1. the distance between gps module and video tx is enough? (I want to prevent any kind of interference)

2. I want to use a 3S 4000Mah battery (http://hobbyking.com/hobbyking/store...idProduct=7634). Do you recommend something else?

3.the pressure sensor sould be inserted in sponge? Should I make a hole in the fuselage for the pressure sensor to work properly?

4. the arduimu should be alligned/glued after that interrupted line??

5. the distance between components is good? Should I rearrange them?

Thank you for your advices.

This is the current setup that I use for autopilot-RTH without any kind of stabilisation.
