EMAX Magnum All in One Tower
The EMAX Magnum is a clean quadcopter builder’s dream. In a small 36 x 42 x 18mm stack, the EMAX Magnum is a 6 in 1 stack that has everything you need to build your FPV quadcopter. Just add the motors, camera and antenna and you’re done!
EMAX Magnum Highlights

See the full specifications on the EMAX Magnum AIO Tower page
The EMAX Magnum is a 6 in 1 stack that has almost everything you need to build the quad. It takes all the guess work out of selecting parts that will work with each other. At the heart of the stack is a super fast F4 processor running Betaflight. It has BetaFlight OSD which lets you customize what you want shown in your display. This allows you to change PIDS from the display also.
The Magnum is sporting four of EMAX’s 30A ESC running BLHeli-S firmware that’s DShot600 compatible. The onboard current sensor lets you monitor how many amps you are pulling in the OSD.
The VTX has adjustable power from 25-200mw and 48 channels which is perfect for racing. The antenna is connected to the VTX via whip or 80mm SMA cable. It has a simple one button operation that lets you select power, band and channel.
It comes with a FrSky XM+ Receiver that can stack on the top via a 3 header pin. If you need to use a different rx it has pads for Spektrum or another FrSky rx like the XSR or XSR-m.
Let’s do a comparison if you were to build a similar stack with all the components the Magnum comes with.
- DYS F4 flight controller with OSD $35.99
- DYS 30A 4in1 ESC $44.99
- TBS Unify Race $29.95
- FrSky XM+ $12.99
This stack of individual parts has similar specs as the EMAX Magnum ($110) is about $124.

Tools I Love
- Weller Digital Soldering Station – this is my workhorse. I’ve been using the same soldering iron for at least 15 years. It’s expensive but it will last forever.
- DeWalt Gyroscopic Screwdriver – freaking love this screwdriver.
The EMAX Magnum is hands down the easiest quad I’ve built to date. Since the flight controller, ESCs, VTX and RX comes pretty much assembled. All that you need to do is solder the motor wires to the ESCs, install the XM+ and solder a wire for the camera…done! It’s a ridiculously easy build.
First, solder the motor wires on the ESCs. Since we are using BLHeli suite, it doesn’t matter which way you solder the wires. You can reversed the motor direction in the software later.
Next stack the flight controller on top and solder the 3 header pins on the XM+.
Next measure out about 1.5″ of wire for the camera wire and solder on to the stack.
Mount the camera. PSH…you’re done with the build!
The BetaFlight setup is pretty straight forward. I’ll post my screenshots of how mine is setup.
These PIDs are nearly stock. I’ll post updated PIDs once I have more stick time.
Post Flight Tip
It’s highly recommended to put Bondic on the antenna mount on the VTX and the SMA extension. Also to put Bondic on the wire that connects to the connector. Mine kept popping off the VTX. Then after a few crashes the wire came off the SMA. Bondic is a super fast setting glue that sets in seconds when used with the UV light that comes with it.
Good and Bad
First let’s look at the advantages of the EMAX Magnum.
- Ridiculously easy to build. For a seasoned builder, you can build a quad from parts to test hover easily under an hour.
- Great price. It would cost more to build a similar stack
- Ultra clean build. Everything stacks very neatly with minimal wires
- Loaded with features in a small package
- Runs BetaFlight
- Easy to change band/power/channels on the VTX
- Questionable quality. Hope it was just mine but the antenna cable came apart pretty easily
- AIO stack. This is the problem with AIO stacks. If one part goes bad, it’s really hard to fix
Should you get the EMAX Magnum?
Would I recommend the Magnum for a serious racer? No, I probably wouldn’t. Racers crash constantly and break parts. I haven’t had enough time to tell how durable with stack is but naturally when you crash things will break. If you needed to replace a component on the Magnum it would be much harder to get specific components. That would be my only hesitation for racers. I’d say the Magnum is great for the casual FPV quad pilot who likes to build clean quads and fly for fun. It’s a great value for the price, clean, loaded with features and super easy to build. Other than that I really enjoyed building with the EMAX Magnum AIO stack.
If you found this post helpful, it would be super cool if you purchased the components from my store or purchase items from my Amazon links. These posts are expensive and take a loooong time to make so the purchases make it possible for me to keep making them. Thanks in advance, I greatly appreciate it 🙂
