the switching between 150Hz and 50Hz is very conservative, cautioning on the side of a reliable 50Hz link and as little switches as possible. this is why switching back also does not happen very soon (hysterisis is large). the range far exceeds a normal race course, and the switching between modes is what causes issues for racers (not the actual link) that is why the force 150Hz mode was made. crsfshot benefits 50 and 150Hz modes. very interesting video!

Thanks for the feedback. I know that as of late more and more pilots are starting to use dynamic power. I understand this likely isn't good for racing. Probably not legal within race rules. But for freestyle, would you say that using dynamic power might reduce the amount of switching between 150/50hz? I intend to re-run this test with dynamic on. And also I'll try force 150hz at 100mW and see if I can get it to failsafe.

@@PinchTune dynamic isnt advised for racing. to minimize switching, dynamic will not harm or help, as the algorithm is geared towards ramping up power first then switch modes. at 100mW you will have troubles getting failsafe in the area and manner that you flew in this video.

@@christopherwhull yes, dynamic power is the default and best way. however, in a race situation the switching can cause distractions to the pilot. and the noise from other crossfire user amplifies the amount of switching scenarios. I'd say for flying as in this video, keep max legal power and dynamic on. if you need the 150Hz, do a few dry runs on the mode and gauge the performance implications for where you fly. if you plan on flying more than a mile, definitely stick to dynamic bandwidth allocation. with friends too. as always, dont overthink it. Crossfire = simplicity. The options to make it complicated are there, though, should you wish to go "under the hood".

Using crossfire at 200 feet is supported but not where it is designed for. Dynamic power should provide better link quality on average. If you have already calculated your link loss, profiled your antennas, polared you signal strength and want to jack with the power setting ignore the rest of what I have to say. This is why unless you are working an edge case leave crossfire in dynamic power. There is the case where crossfire degrades because the rx on either side of the link saturates and the datarate is forced lower when the gain cannot be cut farther by the chipset. Other chipsets i have read the datasheet in this band only have about a 12dB range on the gain. The farther out you go, path loss increases, the more the gain on the rx is ramped up because the RX power levels drop to where the circuit is tuned for on either side. Somewhere out there is where the link becomes ideal. At 400 feet you the loss is just getting to where the RX can start ramping gain to be more sensitive high above the noise floor. You will find you have more LQ variability at 50 feet than 5000 feet for this reason. Dynamic power in modern digital communications saves a ton of droped bits at both short and long paths. It is how it is licensed, been designed for, use it that way for best results in most cases. Love that nobody notices 50hz/150hz on crossfire but they are insane about 6ms in other products. It is like USB latency in gaming, predictable the brain just gets over it except for .3% of the userbase.

I recently ran this same test - a helpful coincidence! The results were surprising! If the quad was 10 feet from me, armed and on the ground, it would switch to Crossfire mode 1 (50hz) IF the null of the Immortal-T was pointed to me. Not what I expected! Two different quads did exactly the same thing. 100mw. Tried both stock and Diamond Transmitter antennas. I've been worried that something is wrong with my Crossfire transmitter, but after seeing your video, it seems that this is just how Crossfire is. It would be interesting to see if you get the same result, if you point the null of the Immortal-T towards yourself. Thanks for the very insightful video!

I think the mounting of the antenna on the quad is the real issue - blocked by a lot of carbon. i used to run a similar setup and was really surprised in some settings how poorly my xfire setup performed (where FrSky outpaced its reception). The Steele "Immortal L" and tuned xfire linear antenna has resulted in wayyyy better performance for me where the quad stays in 150hz much, much longer. I just use antenna tubes. It's definitely more durable for me than the arm mount immortal T ... but not much can beat your setup in terms of durability. Really curious about those new floppy xifre antennas from VAS: www.videoaerialsystems.com/collections/antennas/products/xfire-pro-antenna

I get what you mean about the antenna orientation. But again, I feel that only matters when flying upright and out. If you're flipping around within 500 feet of you you're going to have every conceivable orientation during various points in the flight. The exception would be that yes, the TX antenna put vertically would be better if doing freestyle since you're usually not right over yourself.

Your Immortal T transmitter antenna orientation makes me wince. That orientation is reaponsible for the only Crossfire failsafes I have ever had. I prefer vertical orientation so my nulls are above my head and at my feet rather than out to my sides. I know rock like a 3db whip and get it as vertical as I can. All my long range rigs have a diversity nano with a vertical rx and horizontal antenna to keep me better oriented to the tx orientation.

Yeah, I know, but this isn't an LR quad. I run it like this on racers and freestyle quads because I don't want a vertical antenna always in the way of a crash... The only exceptions would be hooking the antenna up to an arms, where it ends up almost vertical during forward flight, or running an immortal air like Steele. Either way, I feel this is all a bunch of baloney (bologna lol) because no matter the orientation, if you just have ONE antenna and you're flipping and flopping around within 500 feet of you, the antenna orientation matters diddly-squat in my opinion. Haha. With the exception of the TX antenna which would be better if vertical regardless.

I just realized your were talking about my TX antenna. And you'd be right. I normally only put it vertically at races and for LR. The reason for that is I store is flat in my TX bag and never take it off. It's a hassle to loosen and put vertically. Looks like I have yet another test to do. Lol.

PinchTune my extremely informal observation is that pushing aside the issue of nulls and flippityfloppy flying where it’s like impossible to avoid a null somewhere, which i totally agree with - there’s something else about vertical TX (and vertical RX) that seems to perform wayyyy better than flat. Dunno if it’s just better reception on the quad or that the metal handles on the TX drop the SWR on the antenna. (which is something that Trappy and Pavel something something mentioned / tested as definitely being an issue).
