thank you! was looking for the same thing! and was about to make my own then it dawned on me I should check the site 🙂

I finally got the telemetry on the x8r working with the f3fc. I had already configured it in cleanflight. And Per David’s latest video uart2 TX wire is the only one I had to plug to the x8r smartport signal port. Vfas is the voltage, curr is current being drawn, cnsp is current I believe. It was awesome to see how much current is being drawn.

I had originally thought the telemetry would only flow after it was armed however tat was no the case. As soon as copter and controller are in it is passing thr telemetry nicely. Good bye frsky lipo sensor on this copter.

Woot!

you can fly it with 2 x 5000 4s packs if you want, probably wont make it fly that much longer, the thrust is there. However in my experience with these tricopters David has the range figured out for a good experience 2700 4s to 3700 4s. Today I maidened the V4 with 1800 4s 65c packs and i get about 4 minutes of unrestricted flight. Flew it in 20 to 30mph winds today. The copter has so much power and the V4 preconfigured tune is awesome. About the V4 tricopter all i gotta say is damn!!!!!

[Rotorblade]

I used the Test2 firmware to do the one wire pass through via the FC to flash all of my ESC’s and reverse the one motor that needed to be reversed. I used the delay beacon to temporarily help me identify which motor was which and set things accordingly. Then reflashed the FC back to the triflight_0_5_ALPHA2_servo_release_RCE.hex version and ran through all the settings again.

The V4 stock Tricopter forged from the heart of a dying star is ready for it’s maiden flight. Am pumped to experience this recipe.

Thanks Lauka, David and everyone for the awesome information and support!!!!

Is it something you’ve set up Frank with the F3 controllers and a Taranis?

I went through this video https://www.youtube.com/watch?v=-l7K0w8RhaE which helped me out a bit, but the telemetry after starting arming isn’t coming over the the telemetry screen. I’ll have to troubleshoot that a bit.

[Rotorblade]

Following David’s latest triflight setup video I had to try to figure out the same question and that was where to plug in the sbus X8R. I tried plugging it into two ports first before i found the right one. The first one I tried I was able to bind my receiver but after it bound it didn’t work and thats what prompted me to do more hunting and stumbled upon the picture section after trying to mine the description for this information. That’s when I realized it wasn’t plugged into the proper port. I think it would be helpful if there was also a orange link to the diagram in the product description. And I feel a diagram with a little more information on the connectors would be nice. I am guessing that a video on the F3FC may be coming or more information at some point. I know some people who might get the new F3FC who might hold out for a build video. Unless you’ve been building multirotors for a while or gone through David’s previous builds it seems like there is some guess work to the new F3FC. Some people might think the symbology is obvious but I know myself and others would like more information. It is a very sweet piece of gear the new midframe and FC.

Now I am wondering with UART2 if I have to move the signal pin over to the TX spot in order to use the telemetry with the smartport on my X8R? I’d love to not have to drag around my LIPO voltage sensor and see my current use on the Taranis.

Thanks!

I have confirmed what was already said previously hehehe!!!

I am setting up a new V4 tricopter and was running into the same issues. Could connect but not read the ESC’s. I was reading high and low all over the web trying to troubleshoot it, I guess I should have checked here first. I figured I was doing something wrong with silly windows file permissions or usb driver issue but I guess not. Glad it wasn’t just me. I am about to maiden this V4 and am pretty excited!

Thanks for all the hard work and support on this guys!

flips and rolls start at about 4 minutes. I am still learning to fpv fly!!

Every time I fly this mini it is a special experience with a 3s or 4s. The parts in David’s electronics kit offers an incredible flying experience! In my opinion it is on the edge of being innovative and smart. I know everyone is getting smaller with motors and now their starting to put big motor on the small frames. I would have liked to try 2206 2000kv motors, but I felt I should maybe stick to a recipe and try something different and holy hell is this mini tri fast!

[Rotorblade]

The mini with David’s electronics pack and the 6×4.5 props I am able to switch between 3s and 4s and am able to perform aerobatics on both types of batteries just fine.

Batteries I’ve used on the mini tri:
4s 5200mah 10c multistar 430gram
3s 5100mah 8c 3dr 316 gram
3s 3300mah 25c nanotech 270gram
3s 2650mah 25c nanotech 210 gram
3s 1400mah 60c HV hyperion 110gram

Flight times range from 2 to 8+ minutes at fast continuous cruising speeds.

The mini with the 2208 1800s just doesn’t seem to care about how much it weighs.

My craft weight is 440gams with fpv and telemetry module.

Heaviest I’ve weighed it in at is 990 grams so far with the 4s 5200 on it.

I know non on those batteries are ideal however being it is a tricopter instead of a quad I feel he c rating on my batteries just barely fits with the setup. One more motor and my batteries wouldnt have enough c rating. I will grow my small pack collection over time. However now that I know this thing hauls ass and does aerobatics with whatever battery I put on it i now am in no hurry to buy a new fleet of batteries.

And the bigger batteries help it track better in heavy winds.

I hope this helps.

I think your 2200 3s will work fine as long a the c rating is decent. 3s isn’t ideal but it works well.

I am to lazy to swap props and just want to fly and he mini tricopter is the answer.

I’ll bet its pushing 70mph with the 5200 4s. It’d probably go faster when I get the right size smaller 4s to go with it.

[Rotorblade]

The devils nuts? I have about 35 to 40 flights on this mini. Same props still. She’s holding together real well! You can roll or flip in any direction and it barely loses attitude.

That 4s 5200 multistar battery can’t really keep up with its C rating. I get 4 minutes of hard flying before the voltage sag gets low. Still waiting for the postman to deliver the 1800 4s 60c nanotech I ordered.

Everyone who sees the mini tri fly is impressed with the kit, speed, and smoothness.

[Rotorblade]

That explains why my telemetry wasn’t working on my x4rsb. Very helpful stuff.

Is there anything I should be doing to improve my latency if I am using the sbus to cppm converter cable?

[Rotorblade]

I wanted to give a big thanks Lauka, Terje, and others for helping to make the mini tricopter flight experience better.

This is the first mini racer anything I’ve flown and I want be able to provide feedback on the firmware and settings update.

I am running the electronics kit in the shop on 3s large batteries at the moment until my 1800 60c 4s gets here.

I flew triflight .1 beta for the first time tonight with the suggested CLI settings from the minitri shop area. The firmware is a huge improvement over the v3 1.9.0 version of the tricopter firmware.

I initally experienced the yaw moving back and forth throughout the envelope of flight. Now with triflight .1 beta it is smoothed out considerably. I am now able to fly with the pedal to the metal and keep it steady but there still is a little yaw back and forth but it is super minimal.

Again thanks for having this thread here. There is a lot of great information in it.

#29 running triflight .1 beta firmware and cli settings. It’s been flying well.
