Help With a Quadcopter Build

[davida]

Hi! I'm planning building a drone (with the help of markyoe) and I was wondering if you guys could give me some help. Here are the parts I'm looking at:


Motors: 1806, 2300KV, http://www.readytoflyquads.com/rtf1806-2300kv-gold

ESCs: 12A, http://www.readymaderc.com/store/index.php?main_page=product_info&cPath=379_382&products_id=4333

Battery: 3S, 1400mAh, 40-80C, http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=66874

Flight Controller: Naze32 Acro (http://www.hobbyking.com/hobbyking/..._Naze32_Acro_AbuseMark_FunFly_Controller.html)

Propellers: Gemfan 5x4.5

Transmitter + Receiver Set: http://www.hobbyking.com/hobbyking/..._2_4ghz_Transmitter_and_Receiver_Mode_2_.html

Voltage Alarm: http://hobbyking.com/hobbyking/stor...ll_Checker_with_Low_Voltage_Alarm_2S_8S_.html

I'll be 3D printing a frame similar (probably a bit smaller) to a 250.


Are the motors, ESCs, and battery compatible? I'd prefer lifting power over speed; will the motor/battery/propeller combination give me that?


Thanks!

Let's see.

You are going to use a 3S, 40-80C battery. With the 5x4.5 props, the shop site mentions each motor running a 5045 prop will require ~9.66A at 12.6V (and lift 436g). Let's round that up to 10A and add 20% for safety, you will need 12 A per motor. This means your ESCs are good too. All 4 motor will draw 40A max from the battery, so a 1.4 Ah * 40 C should be fine too.

Let's calculate with 400g of lift per motor. The 4 motors will be able to lift 1600g. Unless you are going to print a heavy frame, you should be fine. Lifting power and speed wise.

i would choose the hovership mhq2. i have the extended version for 6in props and its great

I would take a look at the FlySky i6 over the Turnigy 6x which is a bit of a dead end.

or better get it from banggood with the better iA6B RX which support PPM and telemetry

Thanks very much! I appreciate that you showed how you got the result; that'll help me become more self-sufficient with regards to design. : )
Do you have any advice as to better parts (I'm on a tightish budget though) and other considerations?

Thanks, but I'm planning on designing my own. I've got a few years of experience with Blender, and I'm taking a class in Autodesk Inventor, and I like the idea of designing my own better anyway. Thanks again, though!

Sweet, thanks for the advice! I'll go with the first; I'm already ordering a bunch of stuff from HobbyKing, so I'll lump that in with that order. Thank you!

If you do get the i6 you might want to get the USB data cable in case there is a firmware update. Probably won't need it immediately but it's inexpensive to include in an order.

http://www.hobbyking.com/hobbyking/store/__9043__Hobby_King_2_4Ghz_6Ch_Tx_USB_Cable.html

While it's not 100% necessary, HK sells the better 6CH RX separately...

http://www.hobbyking.com/hobbyking/...ver_6CH_2_4G_AFHDS_2A_Telemetry_Receiver.html

which works with this voltage sensor you can use for the main battery.

http://www.hobbyking.com/hobbyking/store/__68414__Turnigy_TGY_CVT01_Voltage_Sensor.html

Unfortunately the i6 doesn't have any alarm associated with the telemetry except for the RX/BEC voltage but still it's nice to have the voltage reported if you decide to get the iA6B receiver

The standard iA6 receiver reports the RX/BEC voltage but does not support any other telemetry.

Thanks very much! I think I'll get those then, but I'll have to watch my budget carefully.

Does that receiver work with CPPM? We are working on hooking it up the davida's naze32 acro.
