Happymodel Crux3 Tinywhoop Review

Today we will look at the  Happymodel Crux3 Tinywhoop which is an ultralight 3-inch miniature quadcopter fit for working with 2s and 1s batteries. Happymodel has been off the market for some time, but now they came back with their newest model. The process began with the Sailfly-x and Larva-x which were both in the 2.5 inches/65mm class. The Crux3 ventures up to an entire 3-inch edge and uses the entirety of their past learnings on causing things lightweight in what I do feel is, even more, a completed bundle. The drone is built with powerful motors and a strong frame. And also, it ships with a different board and external receivers including FRSKY, DSM and now TBS crossfire too. 


  • 115mm size (3″ prop compatible), Toothpick style carbon fibre frame with the protective canopy;
  • Super lightweight (only 41 grams without battery);
  • CrazybeeX FR V2.2 F4 flight controller with integrated 5A BL_S 4in1 ESC;
  • EX1202.5 6400KV motors with Gemfan 3018 2-leaf propellers;
  • Caddx ANT 1200TVL Camera;
  • 5.8G 40CH 25/200mW VTX;
  • Optional DSM2/DSMX, FlySky, FrSky D8, FrSky R-XSR or TBS Crossfire Nano RX radio receiver;
  • XT 30 battery connector (2s 350mah/400mah/450mah/520mah LIPO pack recommended).


There is nothing extravagant to the frame of the Crux3. It is super simple and will clearly be depending on the low weight of the art to dodge harm in an accident. Be attentive in the event that you fly over a hard item or an incessant crasher. On the off chance that you do wish to trade for another casing, this would not be troublesome given these segments are straightforward


Flight controller 

At the core of this lightweight quad is the CrazybeeX AIO load-up. It houses a fantastic measure of stuff: F4 flight controller, 5a 1-2s BLHeli_S ESC, 25-200mW VTX, and an SPI collector. This is a development from the superb board utilized on the Happymodel Mobula 7. However, adds 2s capacity and expanded VTX power, both an inviting reward. The idea of this board implies that you should simply connect a camera. Engines and battery and you are ready to go. No playing with little wires for 5v, ground, UARTs, and so forth. Likewise makes production and gathering a lot simpler for the producer BUT in the event that something bombs you are up for an entirely different board. 


Basically, this is one of the most productive Tinywhoop I ever had. The least demanding approach to demonstrate this is by taking your most exceedingly terrible, most established battery and checking the hang and flight time and this is actually the thing you are finding in the DVR above. The battery utilized was a 2s 450mah 30c battery that accompanied the first Fullspeed Leader 120 that I explored here more than 3 years prior. This battery was refuse path in those days as well! Indeed, even on this shame of a battery, I got more than 6 minutes of flight with the battery recuperating to 3.77v per cell thereafter. On a more current GNB 2s 450mah battery I got 7 minutes of flight which is simply insane. Everything I can say is, ensure your goggle and transmitter batteries are all around charged!


Happymodel has gone with the EX1202.5 engine here which is no uncertainty propelled by KababFPV’s 1s baby tooth 3-inch ultralight quad. Anyway, the decision of 6400kV proposes this has been intended for 2s instead of 1s. Engines are for the most part commonplace of an upbeat model. However, great to see improvement after some time. Standard 4 screw mounting and I can see they have now gone with bent magnets and a more tight magnet-stator hole which should make for better force. Shaft size is 1.5mm which is common for the class.


The camera on the Happymodel Crux3 Tinywhoop is an impressive one. The Caddx Ant camera utilized here is a screw-mounted 14mm wide unit that weighs simply 2g. More great is the way that it has 1200TVL and is completely controllable by means of the included far off for calibrating. I’m anticipating perceiving how it piles up being used. Ideal to see that the canopy has four mounting focuses. They ought to settle the Jello issues from the Mobula 7 and it’s a canopy with just 3 mounting holes.

However, there is a second option when it comes to the camera. The little drone comes with a basic insta360go mount. Yet the mount is really pointless and clearly somewhat of an idea in retrospect. In particular, it hopes to mount with a powerless looking turn keyway that makes certain to help lose your costly HD cam when you crash. Besides, the free mounting will unquestionably give you a serious instance of jello. The quad is not unfit or unsatisfactory for utilizing an Insta360go. However, the provided mount is not the best accessory for it. 

Betaflight setup


Before flying this drone, you should check the Betaflight setup first. If you have already done this, feel free to refresh the firmware and utilize your own setting. If you mess up you can always come back to the default settings, so don’t worry.

Happymodel Crux3 Tinywhoop has truly shocked me, however – it has the most recent firmware (4.2.x at the season of composing) AND all the more critically, it has been tuned – RPM channels, dynamic channels, PIDs, rates, VTX tables. Every one of the things that normally require some investment and experience to set up. The processing plant diff is beneath and the screengrabs clarify the distinctions in default settings.


On the proficiency specifically, I have seen nothing like it – more than 6 minutes on an old 2s 450mah battery. Sure you could fly more enthusiastically than I did above. However this puts it well in front of anything I’ve at any point investigated particularly.

Because of the fundamental AIO load up that has ESC, flight control and VTX is a basic, straightforward quad. FPV execution is very acceptable and by and large. This seems to be a fantastic little bundle that ought to satisfy everybody from the novice middle of the road range straight up to an accomplished pilot. In view of my involvement in it so far I’m extremely satisfied to suggest it as a fantastic quadcopter.
