Tiny Whoop

The small Inductrix of Horizon makes so fun and can be flown with such precision that I modified it to a Tiny Whoop. And so I now have a indoor FPV copter.

The conversion is actually trivial. The standard Inductrix is ​​easily overwhelmed with the additional weight of the camera. Therefore it is recommended to replace the motors against stronger. The Micro Motor Warehouse has in its EU warehouse two suitable candidates, the Medium and Fast motors. I've decided for the medium. Changing the engines is very easy thanks plugged motor cable. With a curved forceps pull the rotors off And then carefully remove the motors, use your fingernails to push them from the bottom, and then gently pull from the top. Push in the new ones and attach rotor - done. Engines with white / black wires are CCW and the blue / red CW rotation. I get rid of the camera body and the plug to reduce the weight. Then it stick with a narrow strip of double tape to the front plate of the camera onto the duct of the Inductrix so that a small angle gives the result that the camera is straight during the flight - at least almost, if you are slow ;-). The double tape is also the isolation between the camera and board. In addition, the camera is secured even with two small rubber bands. I robber it from my daughter, they are actually meant to make bracelets. The power cable of the camera is cut as short as possible and soldered to the board at the battery connector.

At the same time I try to use my smartphone and Android tablet as FPV Monitor and Recorder. It's pretty good and latency is okay for my flight style - slow. Big advantage is you have the videos directly on the phone.

The batteries are charged with my Tiny Whoop 2- or 3-port Charger.

To make the frame more rigid or to repair a broken frame, I created a 3d printed frame enforcement.

Clone

The popularity of Tiny Whoops seams to boost the Inductrix, so that the NIHUI NH010/Eachine E010 appears to be the first clone. I'm curious what come next developed and whether the NIHUI has the potential for mods.

First attempt to record the camera image from Tiny Whoop with my smartphone. Also fpv flying with the smartphone image worked. Unfortunately, had quite a strong interference on the first floor. Let's see why.
