EMAX Repair Start

Hack-A-Thon Part 1

On The Bench – TH2

Assess The Damage, Teardown

Back from the airfield, EMAX Fix – part 1. Be sure to check out the rebuild of in this series in the EMAX Quad Motor Rewire Video posted just before.

The airfield was clear, with no traffic, especially over in the helicopter and quadcopter area, so we were good to go. I unpacked the TH2 from its flight bag, got it out and up in the air with no problems. After a final check of the batteries and controller, we were ready to go. The weather was clear, and according to the flight radar, it was a clear day with mild temperatures and wind gusts of around 2-5mph. So, up we go!

Teardown

Reattach Antennae

Solder Antennae

Antennae Position

Lift is good, strong, and perhaps the easiest part of controlling the drone in flight. These drones when properly tuned , offer a smooth and vanilla flight experience. Be sure to check out the binding process using BetaFlight to bind/connect the flight controller to the remote.

There are a lot of things happening at once when flying the EMAX drones. You have to be mindful of your location, both as you ascend and descend. The flight went well, as planned/expected. I did a few loops, full power, turns, and hard bankings just to set the pace. Don’t forget to check the battery warning before your flight.

Power Leads, LED’s

Clip Leads

Resolder Leads

Clean Power Leads

Set Leads Properly

LED Seated

Now, at this point it was time to bring the TH2 home safely. As you can imagine, trouble came knocking. Damage report, minor issues included 2 LED strips out, severed antenna, severed power leads loose (+positive lead), and burned or malformed poly-frame. We fixed the issues by clipping and prepping for new wires, ordering new LED strips and poly frame, replacing the antenna, re-soldering leads, and shrink-wrapping wires where applicable.

TH2 Repair In Progress

On The Bench – EMAX Tiny Hawk 2

In this case, we are addressing the second half of the build. Just to clarify or set the stage we have returned from the airfield with the eMax TinyHawk 2 in disparate need of repair. this is eMax Fix – Part 2. This is not the first time, nor the last time we will have this drone on the bench for repair.

Total Damage, Repair

While difficult, soldering in new, nano-sized parts on these micro drones requires serious patience. Looking back, the drone may have encountered a gust of wind or air under the drone motor poly-frame; it’s hard to say. The crash wasn’t as severe as others, but the drone ended up sustaining more damage than usual. We’ve had to replace a fan blade, FC, or motor from time-to-time, but nothing like this.

Power On, Visual and Manual Checks, Power Down

LED’s Confirmed

Power On Chimes

Remove Battery

Wrapping up the final steps, we encountered a few minor issues: 2 LED strips out, the antenna, replace positive and negative power leads, same for two of the motor wires, and a burnt out/malformed poly-frame. To fix these issues, we clipped and prepped for new wires, ordered new LED strips and a new poly frame, replace the antenna, re-soldered leads, and shrink-wrapped wires where applicable.
