New iteration of Modula7
Mobula7 is a popular series of nano quads from hobby developer Happymodel. Previous versions, analog and HD, supported 2S or 3S power. This new version is less powerful: it is designed for 1S batteries! Built around F4 X12 5-in-1 AIO V2.0 flight controller including BLheli_S 12A 4-in-1 ESCs, 5.8GHz analog VTX with OpenVTX protocol and Smartaudio, power adjustable: 25/100/400mW. Optionally available with SPI (integrated) ExpressLRS 2.0 or FrSky D8/D16 compatible radio.
Motors and power
The power plant is made up of RS0802 brushless motors at 20000KV. They work in tandem with Gemfan 1610 two-bladed props with a diameter of 4 cm; with a central hole of 1.5 mm. They are connected to a PC using connectors, which allows you to change them if necessary without soldering. Battery connector: PST PH 2.0. Battery recommended by the developer: LiHV 1S with a capacity of 650 mAh.
It is based on the RunCam Split3-Lite hybrid FPV camera, which provides real-time analog video communication and simultaneous recording to a memory card in 1080p at 60 fps. What is the feature of this camera? It is equipped with an additional Blackbox component for recording data from sensors on a memory card. Blackbox can store gyroscope data (ICM20689) for later use with Gyroflow software to stabilize recorded video in post-production. This component is also a voltage booster that is needed to power the camera at 1S. Without a memory card, it weighs only 1.5 grams.
Considering the total weight of the components involved, the Mobula7 1S HD will most likely have a battery life of less than 3 minutes. For the same reason, you should not expect good handling. Also, do not expect miracles from Gyroflow, since the clarity of the images, already weak, will only be worsened by the stabilization algorithm.
Price and availability
The Mobula7 1S HD is now available on various marketplaces for $179 (excluding tax).
