Tiny whoops are widespread amongst FPV pilots for his or her compact measurement and agility, making them extremely enjoyable for indoor flying and tight areas. Nonetheless, getting the perfect efficiency out of your tiny whoop requires fine-tuning numerous settings in Betaflight, Bluejay, FPV, and your radio. On this tutorial, I’ll share some suggestions and information you thru the optimum configurations that will help you get probably the most out of your tiny whoop.

Use BT2.0 or A30 Connectors
As examined, BT2.0 and A30 has considerably higher efficiency than PH2.0, much less voltage sag and extra flight time. In case you are nonetheless utilizing PH2.0, it’s time to exchange them. BT2.0 and A30 has comparable efficiency, and they’re additionally suitable so it doesn’t actually matter an excessive amount of which connector to get.

FPV System Setup
In case you are flying indoors, there’s normally little have to run greater than 25mW energy in your VTX. This maximizes your flight time and reduces VTX overheating.
It’s widespread to have a 5GHz WiFi router in the home, so selecting a VTX channel that’s removed from the WiFi frequency band would possibly improve your video high quality, e.g., Raceband channel 8. For extra tips on selecting FPV channels: https://oscarliang.com/fpv-channels/
For comfort, I normally use two stubby antennas on my FPV Goggles, pointing at 90-degree to one another. They’re lighter and extra compact. The polarization course (RHCP or LHCP) normally doesn’t matter as most Tiny Whoops use a light-weight dipole antenna, which is linearly polarized. For those who don’t know what to decide on, RHCP is a extra widespread selection for analog FPV. See my antenna suggestions: https://oscarliang.com/best-fpv-antenna/#Antennas-for-VRX-and-FPV-Goggles
Radio Hyperlink Setup
Assuming you’re flying indoors and utilizing an ExpressLRS radio hyperlink, think about selecting the bottom energy degree, e.g., 25mW or 10mW if accessible. This may significantly enhance your radio battery life.
On the subject of packet charges, think about using 500Hz and even F1000Hz for minimal latency. Nonetheless, for most individuals, it’s tough to even discover the latency distinction between 150Hz and 500Hz, so it’s not an enormous deal in apply.
Personally, I simply use 250Hz for all my quads to maintain issues constant. Packet price is a world setting, not a per-model setting, so in case you use totally different charges for various fashions, you would need to change it within the ExpressLRS LUA script each time earlier than flying. That may develop into fairly annoying.
Don’t overlook to use the ExpressLRS preset in Betaflight based on your particular packet price, in any other case it might introduce undesirable vibrations.
Flashing Bluejay Firmware
It’s extremely advisable to flash Bluejay to your ESC for 2 causes:
- It permits greater PWM frequency.
- It permits bi-directional DShot, which allows RPM filters in Betaflight.
Hottest whoops just like the Air65 and NewBeeDrone already include Bluejay firmware, so that you don’t have to fret about this.
Comply with my tutorial on the way to flash Bluejay: https://oscarliang.com/bluejay-blheli-s/
Select a PWM frequency that fits your wants. 24KHz gives higher motor efficiency, resulting in extra responsive and exact management, whereas 96KHz maximizes flight time. 48KHz gives an excellent steadiness between responsiveness and effectivity. I examined totally different PWM frequencies on my BetaFPV Air65, and listed below are the flight instances:
- 96KHz: 4:00
- 48KHz: 3:40
- 24KHz: 2:50
You may change PWM frequency by re-flashing the firmware.
Personally I believe 96KHz is an efficient choice to get the longest doable flight time. If you would like snappier motor response, you’ll be able to attempt decrease frequencies, however not like you’re racing on an expert degree you won’t even discover the distinction.
Props In vs Props Out
Props in and props out discuss with the motor spin course and propeller mounting. I’ve a tutorial explaining it in additional element: https://oscarliang.com/reversed-motor-prop-rotation-quadcopter/
Props in is the default configuration in Betaflight, however props out is extra widespread on whoops as a result of it tends to cut back yaw washout and usually leads to higher flight efficiency.
For those who expertise washout throughout corners or descents, making an attempt the other configuration can generally enhance the problem. Don’t simply take my phrase for it — experiment with each setups and see what works finest to your flying model and setup.
Digicam Angle
For those who discover the drone tough to manage and it all the time feels prefer it’s making an attempt to run away quicker than you’ll be able to handle, attempt decreasing the digital camera angle by shifting the digital camera to a decrease screw gap on the cover.
For those who’re already utilizing the bottom digital camera angle accessible, you’ll be able to cut back it even additional by doing one thing like this.
Betaflight Configuration
Angle Mode vs. Acro Mode
I used to fly largely in Angle mode, however recently I’ve been flying increasingly in Acro mode as a result of it permits me to fly quicker and extra easily.
Some pilots nonetheless choose Angle mode for a number of causes:
- Ease of Management: Angle mode robotically ranges the quad when the sticks are centered, making it simpler to manage — particularly in tight indoor areas.
- Self-Righting: After hitting an impediment, the quad rapidly stabilizes itself, permitting for quicker restoration and steady flight.
- Precision: Stick deflection straight corresponds to the lean angle of the quad, which might really feel extra predictable and managed, significantly for racing situations.
For those who’re simply beginning out, it’s completely superb to stay with Angle mode. Nonetheless, if you wish to push your lap instances and problem your self to fly quicker, Acro mode is the way in which to go. Simply bear in mind that it’s considerably tougher to manage and requires apply to grasp.
Angle Mode Settings
- Angle Energy: 75 (greater energy = extra stabilization. If management is simply too stiff, cut back this quantity).
- Angle Restrict: 60 (This controls how a lot tilt you are able to do in Angle mode earlier than it limits it, form of like your charges in Angle mode. The upper, the extra responsive and twitchy your management is)
My Whoop Charges (Acro Mode)
Pitch/Roll
- Middle Sensitivity: 250
- Max Fee: 1100
- Expo: 0.55
Yaw
- Middle Sensitivity: 300
- Max Fee: 900
- Expo: 0.55
Disabling Airmode
I usually disable Airmode within the Configuration tab when flying in Angle mode. This helps with crashing; the whoop doesn’t overreact and freak out, permitting simpler restoration.
For those who fly in Acro mode, you’ll be able to assign Airmode to the identical swap as Angle mode in order that once you deactivate Angle mode, Airmode is activated.

Throttle Scaling vs. Motor Output
In case your whoop feels too highly effective, think about decreasing its energy utilizing Throttle Scale.
Within the PID Tuning tab, Rateprofile Settings, set Throttle Restrict to SCALE, then cut back it to 90%, and even decrease for relaxed cruising.
Keep away from decreasing Motor Output Restrict as an alternative. Whereas it will probably additionally cut back the drone’s velocity, it decreases your drone’s general responsiveness. Utilizing Throttle Scale limits most throttle enter with out proscribing motor authority, so you retain full responsiveness whereas decreasing high velocity.
In different phrases, you’re not shedding flight efficiency by scaling throttle — the motors can nonetheless attain 100% energy when wanted to stabilize the quad. That is totally different from Motor Output Restrict, which caps how briskly the motors can spin and may make your whoop really feel much less responsive.
Throttle Expo
Setting throttle expo helps you fly exactly indoor. All people and each quad would require barely totally different throttle expo because it is determined by your regular cruise velocity, what you need for throttle mid, so it is advisable modify it your self.
For my Air65 II Champion whoop, right here’s my setting:
- Throttle Mid: 0.28
- Throttle Expo: 0.65
Different Settings
- VBAT Sag Compensation: 100% (Makes the quad really feel extra constant via the entire battery pack but additionally extra dangerous as you would possibly overlook when to land).
- Thrust Linearization: 10%.
- Motor Idle: 8% to 10% (Within the Motors Tab). Or use Dynamic Idle.
- Battery Voltage Settings: Set the Minimal Cell Voltage to three.2V and the Warning Cell Voltage to three.3V within the Energy & Battery tab. This ensures you don’t over-discharge your batteries. Set Max voltage to 4.4V.
- OSD Setup: Run a minimal OSD setup with solely important components like battery voltage, flight time, and warnings to keep away from distractions.
Allow Crash Restoration in Betaflight
It is a should have function for whoops, ensure you allow it as a result of most BNF whoops include this function disabled.
What’s Crash Restoration
Crash Restoration is a function in Betaflight that helps your quadcopter stabilize itself after hitting an impediment. This function might be significantly useful for Tiny Whoop pilots, particularly these flying in tight areas or collaborating in races. When enabled, Crash Restoration permits the flight controller to right the quadcopter’s place quicker than human reflexes can, making it simpler to regain management and proceed flying.
Why Use Crash Restoration?
Crash Restoration can considerably improve your flying expertise by:
- Computerized Self-Righting: When your quadcopter hits an impediment, the flight controller makes use of the motors to carry it again to a steady place rapidly.
- Decreased Downtime: By robotically correcting the quad’s place, you’ll be able to keep away from the necessity to use turtle mode or decide up the quad after a crash.
- Improved Flight Efficiency: Particularly helpful for tiny whoops in indoor environments, the place crashes are extra frequent attributable to confined areas.
Methods to Allow Crash Restoration
To allow Crash Restoration in Betaflight, observe these steps:
Open the Betaflight Configurator. Go to the CLI tab. Kind the next command:
set crash_recovery = ONset crash_dthreshold = 80set crash_gthreshold = 600set crash_setpoint_threshold = 500set crash_recovery_rate = 150save
Tuning Crash Restoration Settings
Betaflight gives a number of parameters to fine-tune the Crash Restoration function, making certain it performs optimally with out false triggers. It’s quite a lot of absorb, in case you don’t wish to undergo this, I believe the default works fairly nicely for tiny whoops, you don’t essentially have to vary any settings except it’s inflicting you a difficulty.
- crash_recovery: Allows or disables Crash Restoration. You may as well set it to “beep” to check the function with out precise restoration actions, however not helpful for quads and not using a buzzer, akin to a tiny whoop.
- crash_dthreshold, crash_gthreshold, crash_setpoint_threshold: These parameters management the sensitivity of Crash Restoration. Adjusting these may help stop false triggers:
-
- crash_setpoint_threshold: Based mostly in your stick place, this prevents restoration from triggering throughout intentional flips or rolls.
- crash_gthreshold: Based mostly on gyro readings, this units the rotational velocity threshold to set off restoration.
- crash_dthreshold: Based mostly on D-term values, this detects when the quad is genuinely uncontrolled.
-
- crash_delay, crash_time: These parameters add a delay between detecting a crash and initiating restoration:
- crash_delay: Time in milliseconds to attend earlier than beginning restoration.
- crash_time: Most length for which restoration makes an attempt will probably be made.
- crash_recovery_rate: Controls how aggressively the quadcopter makes an attempt to get well. Larger values imply quicker restoration however can result in oscillations if set too excessive.
set crash_recovery_rate = 100 - crash_limit_yaw: Limits the yaw price throughout restoration to forestall spins.
set crash_limit_yaw = 200 - crash_recovery_angle: Defines the angle to which the quadcopter will attempt to get well.
set crash_recovery_angle = 10
Preserve Your Charges Constant
My final piece of recommendation for freshmen is to maintain your charges constant. It doesn’t matter whether or not you’re flying indoors or outside, or piloting a robust quad or a sluggish one — having the identical charges and dealing with traits is the way you enhance over time.
Each time you alter your charges, it is advisable spend time getting used to the brand new really feel. Holding your charges constant helps you construct muscle reminiscence and progress quicker as a pilot.
It’s completely superb to experiment with totally different charges whereas determining what works finest for you. However with regards to working towards and enhancing your abilities, consistency is essential.
Conclusion
Organising your Tiny Whoop with these configurations and suggestions will considerably improve your flying expertise. Bear in mind, these are beginning factors, and also you would possibly have to fine-tune settings based mostly in your particular {hardware} and flying model. Pleased flying!
