The match between Quadcopter frame, lipo battery, motor and propeller size

This guide is mainly introduce the match between Quadcopter frame, lipo battery, quadcopter motor and propeller size; quadcopter frame materials and how to choose a quad frame. Quadcopter Frame — The structure that holds all the components together. One of the most important part of quadcopter is its frame because it supports motors and other electronics and prevents them from vibrations. You have to be very precise while making it. They need to be designed to be strong but also lightweight.

All parts of quadcopter will be hold on the frame, First , you can decide as to which frame should take? Then, look at the recommended setup of frame to buy other parts. Generally speaking, from 180 mm to 250 mm is most popular frames, more bigger one is from 280 mm to 800 mm even more.

Quadcopter frame, lipo battery, motor and propeller size matching table

Frame Size	Prop Size	Motor Size	Motor KV	Lipo battery
120 mm or smaller	3 inch	1104 – 1105	4000KV+	80-800mAh 1s/2s
150 mm – 160 mm	3-4 inch	1306 – 1407	3000KV+	600-900mAh 2s/3s
180 mm	4 inch	1806 – 2204	2600KV+	1000-1300mAh 3s/4s
210 mm	5 inch	2204 – 2206	2300KV-2700KV	1000-1300mAh 3s/4s
250 mm	6 inch	2204 – 2208	2000KV-2300KV	1300-1800mAh 3s/4s
330 mm – 350 mm	7-8 inch	2208 – 2212	1500KV-1600KV	2200-3200mah 3s/4s
450 mm – 500 mm	9-10 inch	2212 – 2216	800KV-1000KV	3300mAh 4s

Materials for quadcopter frame

Most available materials for the frame are:

• Carbon Fiber
• Aluminium
• Wood, such as Plywood or MDF (Medium-density fibreboard)
• Plastic & PVC
• Fiberglass

Carbon Fiber , One of the most common materials for multi-rotor frames is carbon fiber.It is lightweight but expensive. A great many of its physical properties are perfectly suited to the hobby. The only catch is that carbon fiber is known to block radio signals, which is obviously not ideal for a hobby that depends on multiple transmissions. That means you have to exercise a bit of care in how you place antennas on your craft. It can be used though, and is often. Just be aware that blocked signals are a possibility.

Wood , Build a frame with wood, It’s fast, low cost and does not require much effort. while not nearly as sexy as carbon fiber or fiberglass, is a very good material for this sort of thing. It’s cheap, RF transparent, takes brief structural overloads well, uses simple adhesives and dampens vibrations wonderfully.

Aluminium is widely used for frame, you need to buy parts and have some tools to cut or connect them together. Very lightweight and aluminum can transmit vibration quite well. Aluminum is easy to fabricate and can often be bent back into shape after crashes.
Plastic & PVC , Frame usually be 3D printed with plastic, This material is lightweight, cheap, and perhaps a bit to ugly for your new quadcopter frame as well as PVC.

Fiberglass , Another material you could consider is thin G-10 fiberglass sheet which is easily machinable. This is nice for the body area as it’s RF transparent. It also makes nice motor mounts.

Some tips for choosing quadcopter frame

Some quadcoper frame can be fine-tuned to suit your exact requirements. such as HobbyKing Switch FPV Quadcopter which By allowing you to choose between 380 and 320 mm wheelbase.
In our case we want to build quadcopter so make sure the angle between two arms is 90 degree and also check that arms are not twisted.
If your frame is too big compare to your power setup (motor-prop, esc , battery) it will add extra weight while if it’s too small props will fight with each other.
