This lesson requires the use of a soldering iron, please use carefully and/or seek supervision while building your Gremlin.
Please make sure to program and build your Gremlin with no propellers on the unit, doing so can cause harm.
When testing your Gremlin for the first time, please make sure to check your surroundings and work your Gremlin slowly into forward flight.


Activity

Step 1

BUILDING YOUR GREMLIN

Teachers and students, please follow our awesome multirotor guy TJ in how to build your very own FT Gremlin.

Boot and Flash your F3 Femto Flight Controller, see video for instructions.


Acquire your favorite Gremlin frame.

Tin all of your soldering points, see video for points.

Prep your ESCs, see video for prepping tips.

The ESC prepping along with the main power connection is complete and looks similar to this.

Let's begin prepping the motor layout and wire organizing.

Once the motors are all done, it is time to solder on the satellite receiver, here is the configuration for a DSMX Spektrum Satellite Receiver.

Once you have the receiver complete, if you want to, solder on the Hyperion camera!

Mount the camera securely and angle to your preference, if you are a beginner, go 0 degrees, increase the angle as your skills get better!

Finish the Gremlin by mounting the motors and the top frame, don't forget to secure your ESCs and wires.

Configure the receiver, the board, and your overall flight settings using the Betaflight software. See video for setup tips!

Lastly calibrate your ESCs and find out which motor is not turning the correct way.

Once you have identified which motors do not work, proceed to use the BL Heli Suite software to fix it!

Put your props on, remember to do it right, check your worksheet or the video for clarification.

Go have fun! Get to know your Gremlin, and when you are ready, proceed to lesson 3 of the series to engineer and design your own.

This concludes your lesson 2
