Happymdel have been working away on another toothpick style quadcopter (Larva X), and a new whoop flight controller (crazybee V3). Lets take a look at them in some more details.

Larva X Toothpick Style Quadcoter

I call this a toothpick style, as it is probably closer to a regular 2.5inch quadcopter than a toothpick as it does not use the signature 2 blade toothpick props. That said it is super light at 50g, and has all the other makings of a toothpick build, so if you are picky.. just swap the props for a 65mm version. Looking at the video released by Happymodel it does fly well, but needs abit of fine tuning:

Other cool features include a better camera (runcam nano 2), 1103 7000kV motors. The new crazybee V3 flight controller (more on that below) and a new diamond 200mW VTX that includes a built in DVR.

Where to Buy:

Crazybee F4 Pro V3 Flight Controller

At the heart of the Larva X is the new crazybee V3 flight controller. This new flight controller is Happymodels take on the BetaFPV/GEP RC 12A F4 flight controller. Just like with the other Crazybee boards, this one inlcudes a built in receiver which is great for micro quadcopters, but if you want to use your own, there is also a noRX version. Otherwise this is the same as any other crazybee board except for the new uprated ESC.

But strangely rather than using 12A ESC like on the BetaFPV/GEpRC boards, the crazybee specs only mention 10A (maybe to cover themselves, see my commentary below).

Where To Buy

Many may not find this very exciting given the bad reputation for the crazybee boards burning up. But I just wanted to say, that since we sell theese boards, 95% of the faults are because the crazybee v1, v2, has only 5A ESC on them. Most of the time when the board dies it is because people are using toothpick motors that can draw more than this. I will also say with the first version of the Mobula7 HD, happymodel was slightly careless shipping them with a motor KV that drew more than 5A, so the first batch of mobula 7HD units had an ESC failure rate of 50%. Now that they have the 9000Kv motors, the crazybee boards have a failure rate similar to other FC’s we sell.
