How to Pick Spare Parts for a 5-Inch FPV Freestyle Quad

A 5-inch freestyle quad needs a 225 mm carbon frame, 2207 motors near 1750KV for 6S, and a 30.5 mm stack. Match every part to the same cell count before you order. This guide lists the frame, motors, stack, camera, and props that fit a standard 5-inch build, with live links to each part.

What frame size fits a 5-inch freestyle quad?

A 5-inch frame measures about 225 mm across the motor diagonal. The APEX 5 frame uses 5.5 mm carbon arms, which survive hard freestyle crashes.

Check the stack mounting pattern before you buy. Most 5-inch frames take a 30.5 mm by 30.5 mm flight controller stack.

Which motors suit a 5-inch 6S freestyle quad?

2207 size motors near 1750KV are the standard pick for 6S freestyle. KV means revolutions per minute per volt with no load, so 1750KV on 22.2 V spins near 38,850 RPM unloaded.

An RS2205 2300KV motor suits a 4S build instead. Never run a 2300KV motor on 6S, because the higher voltage pushes RPM past the design range.

How do you pick a flight controller stack?

A stack pairs a flight controller with a 4-in-1 ESC on one mounting pattern. A 50 A ESC covers 2207 motors on 6S with room for current spikes.

Betaflight is the firmware most freestyle pilots run on F4 and F7 boards. The SpeedyBee F7 V3 stack pairs an F7 board with a 50 A BL32 ESC.

Which props fit a 5-inch quad?

Use 5.1 inch props with a 5 mm center bore for 2207 motors. Three-blade props give more grip in turns, while two-blade props give more top speed.

A 3.5 inch tri-blade prop fits a small 3.5 inch frame, not a 5-inch frame. Always match prop diameter to the frame size first.

What camera and video transmitter do you need?

A micro FPV camera measures 19 mm by 19 mm and outputs 1200TVL analog video. The RunCam Phoenix 2 SP V5 adds night vision for low-light flying.

A 5.8 GHz video transmitter at 800 mW gives solid range for freestyle. The SpeedyBee TX800 runs at 800 mW on 48 channels with SmartAudio control.

Should you build 4S or 6S?

A 4S pack reads 14.8 V nominal, and a 6S pack reads 22.2 V nominal. 6S gives the same power at lower current, so wires and connectors run cooler.

Pick 6S for a new freestyle build with 1750KV motors. Pick 4S only if you already own 4S packs and 2300KV motors.

Frequently asked questions

Can I reuse 4S motors on a 6S build?

No. A 2300KV motor on 22.2 V spins far past its design range and draws excess current. Buy 1750KV motors for 6S.

What does 30.5 mm mean on a flight controller stack?

It is the distance between mounting holes, 30.5 mm by 30.5 mm. Your frame must have the same mounting pattern.

How much current does a 5-inch quad draw?

A freestyle quad can pull over 100 A in a full-throttle punch on 6S. Size the ESC and battery leads for peaks, not for cruise current.

Do I need a capacitor on the ESC?

Yes, in most builds. A low-ESR capacitor across the battery pads cuts voltage spikes that can damage the ESC and the flight controller.
