🛩️ ZOHD Drift - Step By Step INAV Build Tutorial

Step by step INAV build tutorial for a ZOHD Drift glider. Full instructions for building the aircraft and programming the flight controller.
The CLI codes:
set max_angle_inclination_rll = 600
set max_angle_inclination_pit = 600
set small_angle = 180
set nav_fw_bank_angle = 35
set nav_rth_altitude = 7000
set failsafe_throttle_low_delay = 0
set nav_rth_allow_landing = FS_ONLY

Sad for your loss. Hats off to ZoHD for coming to the party

Nice video, easy to follow. Wish you would do a dart 250g build though....

[@Graeme758]

This is great. I just bought a Drift after watching a review by Ragthenuts, it arrived this morning. Decided to go with a Matek F411 WSE, despite him having trouble fitting one, that should be here next Tuesday with luck. Already have a Phoenix 2 and a Runcam Hybrid 2. Then found this video. Perfect, apart from the TBS VTX it uses almost identical kit to mine, so nice to have my choices confirmed by someone with clearly a lot more experience than me. And to see how you fitted it, saving me a lot of time. I will be using a 2s 21700 li-ion pack and your tip re the esc will be useful, no point carrying the extra weight if I can't use the extra capacity to its fullest.

[@jamesceastep8874]

Giz: This was a stellar video. Your pace was definitely high speed for a beginner (like me), but your videography was fautless, your audio great, and your use of visual aides (still photos, screen captures for configuration, and your honest sharing of the results of your flight refreshing. We beginners need to know that even the experienced pilots have issues at every step. I loved your use of the tail cam, taking advantage of the 2 cam capability of the Matek 411 WSE flight controller. I'm subscribed to your channel after only this video! Thank! I hope you will add notes to the bottom of your video text with additional conclusions as you find them. Keep sharing. - Jim

[@imadabualia4843]

Wow what a plot twist at the end. Awesome video. I love how you used your own FC and FPV setup. Thanks for the great content

[@helomike7000]

Love your tutorials! Always thorough and enlightening. Bummer on loosing it to the Sea God, but impressed with them sending you a new one. Looking forward to the flights with the new one. Am currently waiting for my new Drift to arrive. Thanks for what you do for the hobby.

[@flyingrock6381]

Those minutes flew by! what a great edit. I wonder what takes more time, building the plane or editing the video! ;) Thanks for sharing and good luck on the next build. Cheers

[@702Wolfi]

Select the new UBLOX7 protocol in the GPS settings. The Matek GPS will then update at 10Hz instead of 5Hz.

[@DeeJayEll]

A roller coaster of emotions! Sorry for your loss. 😩 Great video though, thank you. Got a Drift on the way at the moment so some useful tips there.. Better luck with the next one. 👍

[@mikestevens3570]

Sorry you lost it man, but it was a great video!!! I laughed at the chick saying “it’s soooooo big!” 🤣🤣🤣

[@roblawrence6474]

dude that was a great little video! I really need to finish putting camera gear in my plane and actually fly the thing

[@Steve-O_FPV]

Same here, I need to finish mine as well, and then pray I can fly it. Planes are a lot trickier than quads. I think I am good if I can figure out how to launch it.

[@benakrigg859]

I have had mine since September and is very easy to flight coming from drones

[@jwtfpv8957]

Great video. Love the new tempo. :)

[@BlacksheepMediaNZ]

Great work ZOHD!! Support the peeps that are doing great work on YT

[@MasboyRC]

Nice explain and presentation, thank's for sharing

[@MrKillerHobbes]

loved the music choice

[@TimJC513]

The disappearing OSD items could be occurring when they exceed an alarm setting, which is supposed to cause them to blink on/off. There is something with the Matek boards that fails to do this properly and instead they simply turn off. The fix is to “set display_force_sw_blink = ON”

[@tothehilt]

well done sir. I like your though behind the build.

[@kerrycorcoran4885]

Always the best videos. Sorry about losing your Drift...but another is in the way!

[@taterbits]

[@quilllooo]

I am doing the exact same proyect! Just change vtx and camera hahaha. I mounted the T antenna same place but i am worried about landings with that setup

[@paulthompson6975]

Good informative vid !

[@k1ortia]

Awesome straight forward and well explained build, gutted you lost it though, id be pissed. Never mind. Cant wait for the next build.

[@WompFPV]

epic video mate, im really tempted to get the drift it looks super fun..

[@gizfpv]

Do it, it's a decent aircraft :)

[@WompFPV]

@@gizfpv hi mate, I decided to get the dart 250g instead because of my budget and I've got it all setup with matek f411 wse and gps. It flies really nicely :)

[@gizfpv]

@@WompFPV Ah fair enough, yeah from what I've heard the dart 250g is also a good little wing. Enjoy man :)

[@WompFPV]

@@gizfpv thanks man love watching your videos defo inspired me to get into all the inav stuff coming from fpv quads

[@GoatZilla]

Many 18650 cells have built in features that can disconnect them "internally". Lot of guys don't quite understand them.

[@Jamesn-js1zp]

Where'd ya get your badass wallpaper, flashing scooby, I want it LOL

[@Steve-O_FPV]

Yep, I was admiring that myself.

[@HayBeseret]

Great video !

[@scarfpv]

Great video!!! Can you share the STLs?

[@willsgledhill]

This is a great video

[@graemestevens4947]

All that soldering before you flash the FC? Living dangerously.

[@prathameshkalaskar9250]

2:15, yeah I noticed the camera is little big to fit inside the nose But my question is why didn't you use some oil? 😊

[@tudor.abrudan1]

I have drift with Matek 411se. It flied well, in general (except at take off it's going nose down). At the last flight, over sea, I have lost power, EXACLY like you, it felt in the sea. Because I won't receive another one for free, I have recover it. For start, the flight controller if broken. Esc is OK. Split camera/vtx/GPS, idk yet. I suspect it can be a bug from INAV with this FC..

[@raptr49]

I use the INAV autolaunch feature and have never had a problem. Just throw it and it will climb out until you touch the sticks.

[@tudor.abrudan1]

@@raptr49 it was a bug, 3 years ago, in INAV for a certain version. It was fixed after 1 week with a nea INAV version.

[@chiewy778]

Another excellent build video. Thanks Grahame. For the replacement build, are you going to go back to the same parts or will you change it up?

[@DivisionRc]

What do the cli codes do? should i just copy paste w/o thinking? From my research the galileo is a EU gps system right? Im us so wouldnt that be useless? I already custamized RTH stuff so maybe the set max_angle_inclination_rll = 600 set max_angle_inclination_pit = 600 set small_angle = 180 set nav_fw_bank_angle = 35 would only be usefull for me?

[@gizfpv]

Yes, tbh some of the codes I use are outdated now. For example, it used to be that Galileo could only be enabled via the CLI codes, whereas now it can be enabled directly in the GUI. The same is true for the codes related to RTH. You still want to set the max angle and small angles codes though

[@nestwolfsteiner2292]

great build! could you share the links to 3d print STL files please? Many thanks

[@zcontrol1]

great i bit late but on which pin is the sbus of my receiver connected RX or TX??

[@Madthrax23]

Is it possible to use only the f411 without gps or fpv cam ?

[@kenhaupt1865]

I'm about to start this same build. I have all the supplies and was going to install a runcam split up front but I quite like your setup even better. Did you ever get the new drift set up?

[@OlegBovykin]

Any thought on laminating (or adding strength in other ways) wings?

[@shionenomoto4225]

Optional, but adds way more strength

[@karlkramer6114]

hi..what about the cg.. my one is a little bit rear --what do you think?

[@alexkerr306]

Cool. Cheers.

[@tonyhadiputra]

Nice, its you scooby-Doo 🤪

[@prathameshkalaskar9250]

😂😂

[@AeroStuffFPV]

Nice man! What is the background song?

[@BryonGaskin]

Great instructions! Originally I set mine up with the KOPILOT. Worked great. I really wanted OSD so I went with INAV and the Matek F11 WSE. Mechanically didn't change any servo linkages, but the model drops, it doesn't nose dive, but I have to pull the elevator stick back quite a bit. CG is right on the CG marks.. Any thoughts on how to correct this?

[@gizfpv]

Id maybe think about mechanically adjusting the elevator servo linkage so that the elevator is up a little when the servo is at centre. Or failing that, just do a servo autotrim?

[@peterkoslowksi4462]

Thank you so much for your build tutorial! I‘m quite new to RC planes and FPV and I‘ve just tried to rebuilt the Drift you are presenting in your video. Unfortunately, I‘m not able to configure/activate my GPS on the FC. I‘m using INAV 5, a Matek 411WTE and a Beitian BN 220 GPS. When I configure the GPS on the Ports tab of INAV, it always stays on „disabled“ no matter what I do. The cabeling (UART 1; rx to tx and tx to rx) seems to be correct. The GPS TX LED is flickering blue when I turn it on. Do you have and suggestions?

[@gizfpv]

My best guess would be that there's a conflict happening somewhere on Inav. Do you have MSP also enabled on the same UART that the GPS is connected too? Or is something else enabled on the same UART by mistake?

[@peterkoslowksi4462]

@@gizfpvThank you so much! You directly identified the issue: MSP was enabled on the same UART. The GPS is now working ☺

[@oded_10]

Where can I buy more batteries for him?

[@rizen3467]

Great Video! Do you know if i can use the gps unit which came with the kopilot?

[@markhowe5529]

Hi can you tell me what voltage lipo I need for this model for just flying no FVP etc

[@koolkiwikat]

Solder joint at 00:57 looks like a possible fail point

[@demicheligiuliano]

Is it possibile to have the stl for the camera mount?

[@racingturtel5002]

How much does all of it cost

[@Emerald-Cactus]

I know it's a little late but any way you could share those 3d print files?

[@demicheligiuliano]

The same for me...where I can find the stl of the mount of fpv cam

[@igeekw2u]

hey! would it be easy to have links to the stl you have printed for this model or maybe the files themselves if you are the designer??

[@blackbirdboy1]

Ah man, such bad luck. Hope you get the new one in the air soon.

[@jlacleveland]

Where find the runcam split nano case thanks

[@Imagine-FPV]

Great video. Are you willing to share the 3D files. I’m intending to do the same build and that would save me a lot of time. Thx

[@Knemer1990]

I am doing this build now, I am having a issue with the GPS it is powering on with both blue and red lights but when i enable uart 1 and set it to gps and save and reboot, it then reverts back to only the uart being turned on and the sensor goes back to disabled? Any idea?

[@gizfpv]

Check that you don't also have MSP enabled on UART 1?

[@Knemer1990]

@@gizfpv thanks man. That was exactly it.

[@Knemer1990]

The very last issue i am having is with my crossfire nano diversity rx. I have it bound to my tx and showing connected. I have channels1 and 2 pins on the nano rx connected to uart 2 Rx and TX pads on the f411. I have channel output in my tx for channels 1 and 2 set to crossfire Tx on 1 and crossfire rx on 2. I can not get any response in inav from my TX. I have all the settings in the receiver tab of inav set as the following taer, ch12, serial, crsf. I have the serial rx tab switched on under uart2 of ports as well. Am i missing something else? Much appreciate your help.

[@gizfpv]

@@Knemer1990 Hmm, not sure. My best guess would be to check the wiring between the receiver and the flight controller. The tx wire on the receiver needs to go to the rx pad on the flight controller, and the rx wire needs to go to the tx pad. It's easy to get them backwards

[@Knemer1990]

@@gizfpv flashed the fc a few times and it finally recognized the rx input. Thanks for your help.

[@AerialWaviator]

@GizFPV Any update on the ZOHD Drift project for 2021? Am curious what changes/improvements you plan to make? eg: since you preferred rear-view camera, will you choose higher quality camera/VTX. There are also a couple new(er) FC options. ;) BTW: Would love to see some Drift flights along that cliff and beach, looks to be epic scenery. :)

[@gizfpv]

Not yet. I received the replacement from Zohd as promised, but it's still in its box waiting to be built. It is on my list of things to do and hopefully will get done in the Spring. Have got a few ideas for improving the build 2nd time around. Gonna try use much lighter parts, and will also see if I can get it sub 250g

[@AerialWaviator]

@@gizfpv Great, thanks. Just received a Drift and thinking how to configure. It's winter where I am as well, so have couple months of rainy season.

[@hubsessed]

Question for you. Why have a low voltage cutoff set to 5v when your FC shuts down at 5.8v?

[@gizfpv]

The FC will keep working all the way down to 5v. Think about it, when you connect your FC to your computer via USB - that's a 5v supply

[@hubsessed]

@@gizfpv true, but the fc stepping down the 5v power from a higher voltage. If the battery drops below 5.8v (according to Matek CS), then the voltage will not be able to maintain the 5v stepped down voltage. Drop below 5v and the FC wont work. Maybe I'm wrong, but this is how I thought it works

[@dan2384]

Can't find link to your ESC.

[@gizfpv]

There's plenty of places that sell them online. I just had a look and Banggood stocks them. You can use any small racequad ESC though, the brand doesn't matter :)

[@jwtfpv8957]

What did it weight?

[@WX4CB]

nice video.. but what with the 70's porn music ? :D as far as the osd, make sure that you have the same standard across both cameras. also, you got STLS for the vtx box and the split box ? and the same thing happened to me with my liion pack... one of the cells died... even though they were brand new, but luckily i was los with it so managed to watch where it "drifted" down to
