I’ve crashed and bashed and literally burned this thing! I HIGHLY recommend building one, but also HIGHLY recommend not building it as an initial foray into quadcopters. It’s an overpowered 2+kg beast that will rapidly get your attention in a bad way if you aren’t careful. It’s also an extremely expensive set of lessons learned…
For a more docile first build, the Hexsoon EDU-450 is a perfect candidate. I have one and have truly enjoyed building and flying it.
Presently, this one’s been resurrected with an iFlight Blitz 80A all-in-one ESC and iFlight Xing 4214 660 kV motors.
The Lumenier ESCs are pretty awesome until they’re not…and I’ve had three turn into “not awesome.” I can nail down the reason for only one of those failures as my own fault. The upgraded power train mostly resulted from some curiosity about prop size - I wanted to drive bigger props under 6S power.
I have a very simple conclusion to all of my fiddling with props and powertrain:
The original 4S batteries and Gartt motors were outstanding choices and suit this frame extremely well. 13x4.5 Master Airscrew MR series props resulted in lowest hover current/longest flight time. The big ESC and 4214 motors I have now are overkill and unwarranted.
I’m flying Master Airscrew 11x10 3X Power props right now at a slight penalty to flight time because they are very smooth, and the tune is REALLY crisp! I’m certain it’s more than capable of impressive aerobatics, but my wallet says I shouldn’t try that…
I’ve also moved away from FrSky RC hardware in favor of ExpressLRS. It was an easy transition, and I haven’t looked back.
I added a TeraRanger EVO LIDAR for height sensing, which has been a welcome addition on more than one of my builds now.
The Here3+ CAN-based GPS/compass module is also a solid offering from CubePilot and resides on two of my builds, including this one. The M8P makes it easy to use my mower-motivated RTK fixed base when I fly, and it’s fun to see it “stick” an RTL landing at exactly the spot from which it lifted off.
As for cameras, I crashed the snot out of the cheap gimbal setup quite early on, and video duty now falls to an Insta360 X1 or GoPro. I think those are the correct “budget” choices for video at this level. If a gimbal is truly required, you’d best budget for a good quality one capable of swinging a nice camera (that’s gonna cost a pretty penny!). I have forgone the VTX/FPV rig on this copter for now, but I’d use a CADDX setup and recent model DJI goggles if I wanted to install another.
Many thanks to @andyp1per’s 7" build series and the tuning advice therein. I adopted many of those principles as this build has morphed over time.
Here’s the most recent incarnation with all the electronics buried inside and battery on top, close to the prop plane:
