Frame

...

DJI FlameWheel F450

• Cost: 169€
• Size: 450mm Diagonal
• Weight frame alone: 282g
• Takeoff Weight: 800g-1200g (1600g? Depending on sources)
• Will need cable ties
• Power distribution board already built in
• Propellers included

3S will presumably be enough
For weight reasons: probably ca. 2000mAh?
Price: ca 20€ (might be less, depending on shop and our choice)
Output: 11,1V
--> Voltage Controller (e.g. IC7805) required, probably multiple? Low cost, Arndt will bring some, maybe we can buy them off him, if he doesn't mind?
--> May need some that are lossless? -> mc35063 but higher cost!
--> Some people say we will need a step down module, because Voltage Controllers will offer too much variation in their voltage/current: http://www.electrodragon.com/product/lm2596s-adj-dc-dc-small-tiny-adjustable-step-down-module-3-40vin-1-5-35vout/ is recommended, but only outputs 3A?

==> Need a lot more information, might look into it more tomorrow?

LiPo-Warners

Cost: 5-10€

Connection to the microcontroller will have to be done by ourselves. So I don't know how many pins we might need. Will have to talk to someone who might know more, internet doesn't really give much insight. Maybe I'll make a post about it somewhere?

Motors

DJI Motor 2212/920 rpm/V

• Voltage: 11,1 bis 14,4V
• Standard Current: 15-25A
• Max Current: 30A
• Required Batteries: 3S-4S LiPos
• Weight: 56g each (including Propeller Adapter)

In case this helps anyone...I don't think my calculations were correct so it didn't help me much

Electronic Speed Controller (ESC)

DJI Brushless Regler 30A OPTO (?)

Don't need much information. They'll work with our setup.
