This is awesome and Rotorflight is simply amazing. I've been using RF since v1 and the most challenging part was the setup and unfortunately there weren't many setup videos or instructions available so you had to work it out through trial and error. The recent RF2 release, and all the new FCs have changed everything and it's now so much easier. RC helis have a bright future!

[@RCVideoReviews]

Agreed. This is a great starting point. As usage grows, I'm sure RF will continue to be refined and improved.

[@lulafpv6435]

Thank you so much for videos RC video Reviews , just bought radiomaster tx16 4-1 with a external module elrs, i was thinking to buy Ikon2/brain2 because i wasnt sure for try setup Nexus , but with this videos , i Will try Nexus for get all integrated , ty so much , It helps !

[@RCVideoReviews]

Very glad to help. Thank you for watching.

[@beenflying1]

Thanks for this video. It made much more sense the second time I watched it. I have one pre-ordered now...

[@RCVideoReviews]

You're welcome. It will probably be a lot easier to follow along when you have the Nexus and can go through the settings.

[@user-tg3jh1gz7m]

Great work guys unit pre ordered will be using this guide when it all turn up

[@RCVideoReviews]

The Nexus will change things for helis. Good luck with the journey.

[@heavyjohnny]

I just pre-ordered 2 Nexus units to replace the controller on my Goosky RS4, as well as 4 receivers to replace some Futaba satellite receivers I have installed currently on other helis. Looking forward to the seeing more setup videos on this unit! Thanks!

[@RCVideoReviews]

We'll do more. This was a first attempt to get people what they needed to get in the air. There is a great deal of flexibility in Rotorflight leading to a great deal of configurability.

[@RubenRC94]

Great video, Im getting a Omp M4 MAX soon. with your video and the one Jonas Wackenshouser made the nexus is a lot more understandable. On some facebook groups and forums Rotorflight cought some flak for being inpossible te setup. But from the video and the online manual i find it all pretty understandable. Nothing crazy other fbl units dont have, just a little more "clunky"at times. It defenitly convinced me to get a Nexus to pair with my X20s on ethos. Keep up the grest work!

[@yodecaf]

Had to pick one of these up. You could get 3 of these for 1 spirit gt!

[@RCVideoReviews]

Yeah! This device is going to change things for heli pilots.

[@yodecaf]

@@RCVideoReviews i think the next thing has to be making an FBL like a transmitter is with planes. If I have 4 helis, why do I need 4 fbls? Why can't the connectors be simplified/digitized and the piece that holds the fbl locked/unlocked. I'd love to just snap the fbl off and put it on another heli and select that "profile" for the fbl

[@RCVideoReviews]

Neat idea but probably not much in the way of incentive for manufacturers or developers to put effort into this.

[@rolandprobsting4180]

Does Rotorflight make it possible to maintain a minimum altitude - i.e. to automatically go into rescue mode if the altitude falls below this - as with the Spirit?

[@10fantic]

I asked the same question. I hope we can get an answer on it so I can preorder.

[@RCVideoReviews]

I don't believe it supports a hard deck in the current iteration; however, with the presence of barometer, the key hardware is present. I'm looking into whether or not it reports altitude via telemetry, because if it does, you can do something like while we wait for a built-in RF configuration option: this kzbin.info/www/bejne/rWPJqJqMd82YbtU

[@RCVideoReviews]

From the wiki: www.rotorflight.org/docs/Tutorial-Setup/Configuration#barometer: "Barometer This is used for Altitude hold Rescue which is currently still being developed"

[@user-he8pg9zb4k]

Is it necessary to run esc telementry within rotorflight and nexus?? Im not so fussed with all that i just run a conservative flight timer. Great vid by the way 🤟😄

[@RCVideoReviews]

Not at all. I do it because I like things like voltage from the battery. You can definitely tone down the feature set to suit your needs though.

[@chargestate42]

Will you be doing any radio setup videos? The default channel on my TX16s is throttle on channel 3, do I have to move that to channel 6?

[@RCVideoReviews]

Part 2 is coming up. It’s the EdgeTX setup video.

[@scooper1818]

Normally aux1 ch6 is pitch and throttle is lower one depending on transmission standard. Is there a reason you remapped? Or is this some strange rotor flight thing

[@RCVideoReviews]

Aux1 isn't channel 6 in EdgeTx, it's Ch5. The ELRS mapping default in Rotorflight is set when you select the ELRS dropdown.

[@10fantic]

Does Rotor flight have a heard deck feature? Since I se it has a barometer I hope it either has it already or will like the spirit GT fbl with an adjustable hard deck rescue feature.

[@RCVideoReviews]

To my knowledge no. However, it does have the facilities for this type of feature. i.e. barometer. I'm looking into altitude telemetry myself because with altitude on the radio, we can do things like this: kzbin.info/www/bejne/rWPJqJqMd82YbtU

[@pilotman520]

Where can you find blheli esc with enough power for a helicopter? Only seeing 50-60a like we run in quads. I like the idea of having the governor right in the flight controller.

[@RCVideoReviews]

AM116 works on my Raw 500.

[@JensAstrom]

So for a smaller heli, like a RS4, I guess T-motor AM 66 would be fine. Are you planning a video with the settings in the T motor ESC for a heli?

[@TheHillsHaveFPV]

there should be a switch & warning to disconnect the servo linkages before messing with the servos tab. like there is a switch & warning for the motors tab,

[@lesogorp]

Not a bad feature request, I'm sure this would be considered for next versions !

[@claudevandaele4402]

Where do we connect the Spektrum SRXL2 (4 pin connector), is the SBUS port (UART?) an option with custom connector (servo plug) without gray cable

[@4CFPV]

SRXL2 connects to a UART TX. This video explains set up for Betaflight, which will be the same as Rotorflight. Ignore the parts about using a specific firmware. The video is old and SRXL2 can now just be selected from the drop down menu. kzbin.info/www/bejne/jXLOdalvnN-fb5o

[@RCVideoReviews]

I'm not familiar with Spektrum, but all of the ports are UARTS. The DSM port is 3 pin, SBUS is 3 pin. The others are 4 pin. In the configurator, you can assign Serial RX to UARTS 1,2,3,4,6 with AUTO, then on the Receiver page you select your protocol. Spektrum DSM/SXRL2 are both listed.

[@claudevandaele4402]

@@4CFPV Thanks for the reply

[@Malzanar2010]

"gear ratios are super important, you dont want to round anything off", but it automatically rounds it off...

[@RCVideoReviews]

You don't enter the ratio in the tool, you enter tooth counts which are whole numbers. It will calculate the correct ratio based on the tooth counts (whole numbers) you provide. In the event of two stage hardware like the Kraken, review this guide: www.rotorflight.org/docs/Tutorial-Walkthroughs/Two-Stage-Gear-Train-Ratios

[@Malzanar2010]

Yeah the one that’s giving all the trouble for me is the tail, which has a 4.9:1 ratio. The manual gives a “main gear” tooth count but nothing for the tail haha

[@tyran370]

​​@@Malzanar2010I don't think tooth count actually matters except for calculating the ratio, so you can probably just enter 49 : 10 to get 4.9

[@zjangske888]

Pretty complicated if you ask me, stopped watching, not a flybarless for me

[@lesogorp]

It will only get easier... This is 2.0.0 :) Many more releases to follow

[@RCVideoReviews]

It's no more complicated than iKon or Spirit. Just different.

[@lesogorp]

@@RCVideoReviews everything is difficult/complicated until you learn it.

[@RCVideoReviews]

Exactly. The first time I opened iKon, I wanted to go running back to Betaflight.

[@TheHillsHaveFPV]

first time setting up betaflight for a quad its complicated as well but then things make sense and becomes easy im sure the workflow and setup will become easier as its developed. its an opensource project so everyone in the community can help streamline it maybe a 'setup wizard' would be useful
