How to set the Betaflight for Mobula7 Mobula 7 HD FPV Racing Drone
https://qwinout.com/blogs/news/how-t...a-7-mobula7-hd

For Beginners,it might be a little hard to understand the betaflight setting.
Here let us try a easy way to process it,Hope it can helps
1.if you buy the BNF Version,you need bind the transmitter to the receiver first after receive the drone
Please read the user manual before binding,set the transmitter at 5ch and 6ch like the picture below shows

like the picture shows,at the first line,choose Aux1 ,set the 5ch ,it is the start up switch
the below 3 lines ,you can set the modes,set the transmitter 6ch,then choose Aux 2,you can set 3 modes according to your transmitter,but the 3 modes cannot coincide.
please note that the switches on your transmitter which has been set as 5ch or 6ch cannot be used for other modes,or your drone will cannot fly.
hope this can help you,if anyone has better ways,welcome leave comments and discuss with us,thanks

How to connect a External receiver for Mobula 7 Mobula7 HD
https://qwinout.com/blogs/news/how-t...a-7-mobula7-hd

If you get a Drone that does not have the receiver you want,how to process it ?
Here let me show you how to add an external receiver for a Mobula7 or Mobula7 HD
As we know,Mobula7 FC Built-in receiver,if the receiver builit-in is not the version you want,you can add an external receiver directly
Take Frsky receiver as an example

how to connect it?
first,you need not remove the exist receiver,because it will broke your FC,
then,weld the frsky receiver to your board directly,like this ,just weld the IR1 ,5V and GND

Happymodel XT30 Plug Pigtail Power Wire 100F Capacitor for Mobula7 HD Sailfly-X TRASHCAN UR85 UR85HD Crazybee F3 / F4 PRO Parts

https://qwinout.com/products/1pcs-2p...6316c0b5&_ss=r

Wholesale link
https://qwinout.com/products/wholesa...6316c0b5&_ss=r


Wire length: 70mm(include xt30)
Height: 2.6gram
Used for : Crazybee F3 / F4 PRO series flight controller
Can avoid the risk of burning the mosfet or the 5v regulator at the moment of power on
With this Capacitor , we can use 3S 300~350mah battery for the Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1 , and 2s 300~350mah battery for the Crazybee F4 PRO V1.0
And if you want to use the battery above 350mah , we recommend use 220 uF or above capacitor.

We found most of the 5v regulator and esc of the Crazybee F4 flight controller burnt after mod the PH2.0 to XT30 . Also, more powerful the battery is(lower esr than stock battery) , more possibility to fail. And, the temporary solution is add a low esr capacitor onto xt30 connector. This capacitor should have a esr less than 0.2 ohm and have a capacitance more than 100uF. Rubycon ZLG/ZLH series and Samyoung NXB series are what we have tested and recommended.
Following pictures show what happened after plug in battery:
Without 100uF, the max spike voltage increase to ~25v while with 100uF it decrease to about 20v, which is acceptable to Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1

it seems that many people are talking about cinewhoop,and many factories in China are producing cinewhoop FPV Drones
but what cinewhoop means ?
As far as I am concerned,cinewhoop is a frame kit that can carry a Camera like GoPro Hero 7
like these drones ?

Warning:
https://qwinout.com/blogs/news/mobula7-warning

This is indoor copter, Cant be flying outdoor when there is wind!Cant be flying too high to affect the sight!
It is necessary to go to a place with a large space to play it (Especially the novice must pay attention)!

If the Copter collides with items such as walls, you must timely lower the throttle! Otherwise ESCs and motors may be burned, and battery may be burned or exploded.

About the Li-po Battery:
1s=3.7v is the best retention voltage for the copters battery. After fully charged, it is about 4.2v. The battery voltage is below 3.5v for over-discharge.

2s=7.4v. After fully charged, it is about 8.4v. The voltage is below 3.5v 7.0v for over-discharge.

The battery that just flying used cannot be charged immediately (it will cause damage to the battery).

If you have any questions, such as binding Remote controller, please contact our customer service, we will provide technical services in a timely manner.

Driver download:


Before Flying, Please check if all screws on the motors and other place are secure.
The welding part of Flight controller is easy to be damaged , Please connect the battery and the copter kit very carefully. (Take out the battery a little first and then connect it to the flight controller. DO NOT tug on the cables with the flight controller directly, or it will be damaged)

Please connect the battery in the right way (Red wire to Red wire, Black wire to Black wire). Wrong connection will damage the Flight Control Board.

The ESC/Flight Controller/Motor/Battery and other accessories are damaged due to personal flight errors. Please purchase accessories to replace them yourself.
Thank you for your cooperation.
