EMAX Fix – Part 1

EMAX Repair Start

Hack-A-Thon Part 1

Lab Work – EMAX Fix – 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.

EMAX Fix – Part 2

TH2 Repair In Progress

eMax Fix – Hack-A-Thon Part 2

Lab Work – eMax Fix – Part 2

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. If you are interested in getting into drone flying, check out more EMAX Drone Kits, Drones and more here.

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

Read eMax Part 1 if you would like. Also, be sure to watch the successful rebuild video for this series EMAX Quad Motor Rewire Video which was posted just before the wrap-up article.

Additionally, similar Emax status update, time has moved on since the original article and I wanted to share additional Emax content where applicable. If you’re looking for Emax content, give these a shot (in reverse order from this postings date) – Drone Accessories, ReFit Emax Flight Controller, and TinyHawk 2.

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.

DJI Fix

Gimbal Issues

Gimbal Motor Replaced, DJI Fix in for now

Lab Work – DJI Fix

Back To The Field FIXED. After 25+ days

I received some good news today, and even better news is that I got my DJI Phantom 4 ProV2 back from the repair shop. After waiting for roughly 30 days, it’s finally time to fly! The shipping and return process was a hassle, but I leave that for another post. Today, I finally received the PH4 in the mail, so it’s time to fly. I now have the package in my possession and am working on unboxing the drone as the excitement builds. Let’s see if the drone gimbal is ready for flight.

Gimbal Issue Resolution

Does the drone fix meet your expectations? This is the follow up article on the DJI Gimbal Issues. Sounds like the gimbal assembly was replaced, not sure about the camera or if the assembly is self contained, one unit; meaning the camera, gimbal and housing are all considered one replaceable unit. How long would it take to get the drone fixed? ~30 days. ReviewDJI P4ProV2 specs, make sure its your drone and in working condition.

At the airfield we pushed the drone hard, making sure the motors were good to go, a number of gimbal checks, gimbal, motors and lens filter changes. We can wrap up with a positive day at the airfield, nothing of significance to report. Just photos and videos to clean up, and clean out.

Update to come, will include video of the airfield, highlight different maneuvers and views. Or just check the above post…

Now that we have your attention, let’s delve into the DJI Phantom 4, gimbal issues, flight testing at the airfield, video and photography capabilities, and more. The same for our other drones, learn-to-fly drones, racing drones as well as maintenance and tips and hacks to ensure these drones stay airborne.

DJI Gimbal

DJI Gimbal Issues

DJI Blunders, Days Wasted Away

Lab Work – DJI Issues

Diagnosis: bleak… The DJI camera gimbal is inoperable, with the 45° gimbal tilt consistently shifting to the right of center a known issue straight from the factory…

DJI Gimbal: Alignment issues are present from the start. The gimbal is off-centered, indicating potential trouble with the camera and motor. This is a repost from Twitter prior to X, where I wanted to share a message that detailed a 24+ day duration from workshop-to-DJI process and back.

PH4 Gimbal Issues

Power Down

Repack Repair

Next, please keep in mind that ‘repair days’ are counted by the number of days the device is in repair. ‘days in repair’. Additionally, it is important to note down time includes DJI facility time – pre, post shipment and travel time. Whether it is in the US (possibly CA) or abroad (** the total # of repair days do not include ‘in transit’ days… times are not presented online in the DJI UI – status tracker **). Just be aware, times aren’t always accurate. If you prepare for this inaccuracy, or system latency, you’ll be better off with some of the repair ambiguity. This information may come as a disappointment, but it is good to be aware of it now. From a customer’s perspective, this experience was a nightmare.

Just to clarify, ‘Hey, we don’t count the time it takes for the device to travel to and from the customer and DJI, we apologize for any confusion. It is safe to assume that most of us, myself included, do not have a spare Phantom 4 ProV2 just sitting around. Perhaps the issue is related to a defective gimbal or defective gimbal motor(S). In this case, a brand new drone was sent back to DJI for repair. Let’s bring this nightmare to a close and conclude the DJI Gimbal matter, as I would prefer not to encounter any issues straight from the factory. That said, let’s cut to the chase, here is a quick peek at the DJI Fix article some 30 days later.

Other Robot and Drone Repairs

Although this drone is under warranty or we may be ‘under-the-hood’ trying to fix this problem ourselves. That said, learn more about drone and robot repair? Read our series on the Maytronic Dolphin Nautilus CC Plus – Dolphin Down, in need of repair, under repair and Dolphin On, robot back to work in the water. Down time is money being spent, work not being done and more importantly, reducing your Return-On-Investment (ROI) – money paid to purchase a robot to do said work, compared to the manual labor to keep the pool clean. I’d say this has huge potential for those pool owners looking for a little more in-the-pool time versus pool care and maintenance time. How about Apple repairs, M1 Chip repair, or MBP Batter Swap

Learn & Apply

Are you Results Driven, How do you become Results Driven?

Being A Results Driven Organization

Methodology – Learn & Apply

First, Learn & Apply… What was your hypothesis? How did you test it? What did you learn from the test results? Any viable ideas? Did you retest and test again? Do you need to test once more?

Secondly, the challenging part arises: where do we apply our learnings? Do we cease learning? The answer is certainly no. The question then becomes: when and where should you begin testing again once you’ve implemented a change, reduced redundancies, or enhanced system improvements? The time to learn is now. Or is it time to apply those findings elsewhere and make further adjustments to redundancies or system improvements? Does it sound as simple as that?

Thirdly, there are often more questions than answers, so it’s important to always strive to learn and apply new knowledge. If we stop learning, our progress may also come to a halt. Remember, you have the power to make a difference in your business, with your people, and for your brand. Lastly, we advocate for achievable changes and encourage continuous testing. We test, retest, and test again to learn from behaviors, analyze results, and effectively implement change.
