Just took a total of my shopping list so far
Quad Kit - $171.55 US
Undercarriage - $4.09 US (spent more than this but didn't need to)
Radio and receiver - $85.65 US
Servo cable Male to Male x 15 - $22.73 US (didn't need these, a perfectly suitable cable comes in the kit). Do need another cable for stabilised mode tho, and will need additional male to male cables down the track.
KK2.1 Flight Control board - $33.98 US
Propeller balancer - $16.30 US (don't really need to buy this)
1450mAh 3S transmitter lipoly x 2 - $15.16 US (don't really need to do this, but would have to buy batteries or ni-cads either way for transmitter)
2 on board lipoly low voltage alarms - $3.98 US
Fatshark Teleporter headset with camera and 5.8G TX - $235.74.99 US
16 x replacement props - $20.66 US
Atmel Atmega Socket Firmware Flashing Tool - $23.98 US (don't need to buy this)
Shopping list total so far $633.82 US (well over the $700 AUD mark)
So I guess people may ask if a kit is worth it. I still have flight batteries I have to buy, possibly 4 or 5 more, otherwise I'll be flying for 10 minutes and recharging for 3 hours with one battery.
My train of thought is, would I be able to say to my missus "can I spend $700 now on something completely self indulgant?" and she would say "No", but I can do this by buying the bits and pieces I need over time. This list is certainly not complete, and to a degree I am probably hiding the true cost from myself, but conservatively I don't expect much change out of $1000 once I get the camera gimbal I am after for in-flight recording.
I haven't compared my shopping list with a complete kit like a DJI or sawed-off's quad (not even sure how 'complete' these kits are), but I'd be curious to see which is cheaper, a complete kit, or a piecemeal kit and buying the bits and pieces required to do simple FPV.
