... you're gonna walk down and up at today.

Makes sense, thanks JB

Super impressed with what Ghost seems to be doing (and guessing Flysky's new system as well). That said, if I already have CF, is there a solid reason to switch? For racing, does range even matter? I would figure that most venues are setup for normal FRSky 2.4ghz. Also wonder if telemetry matters for racing, if you are going to have goggles on. Seems like lots of people even just use XM+ Rx for racing, so they don't even have telemetry at all. In regards to number of users that can be in the air, aren't either mostly limited by the 5.8ghz video bandwidth? Seems like there are only about six channel/band combinations that can be used without interference.

BTW, as a fixed wing pilot, I would really love to see ghost have something like the CF Nano, that can support 6 PWM channels without a FC. That is still a major selling point for CF for me. Seems like no one else has anything close to that it a Nano Rx form factor.

@@aviphysics at release the ghost atto rx has 4pwm channels, it's not 6, but should be enough for simple planes/wings. Coming soon is a smaller rx, which probably doesn't have pwm. Worth asking immersion rc to build what you're looking for.

I'm also thinking that 2.4ghz might have more clean reflections in that environment, combined with wider band, made the signal enter the staircase straight, but reflected down. If so, that would probably apply to other places like bandos too. Higher frequencies penetrate less, but it also requires smaller holes to enter.

😅

Exactly. I don‘t seem to see the benefits of ghost over crsf. Ghost seems to be more expensive and less tested, sticking to crsf for now.

Bro tell me about it, almost up to 15 running quads.. smh 🤦‍♂️ Addictive? Nah.. 😅

You swiped my comment, no swiping. Thanks Joshua.

More like props but yeah lol

I'm not sure if I saw such module on a render, but they will come up with one for sure..

They are releasing one, just not out yet

Most definitely! I’ll drop my R9M Lite Pro if so.

Get the adapter from BG. It’s 10$. Ordered it last night. Just waiting. Just got crossfire and next payday I’ll order Ghost. Can’t wait to see how well it works with my ORQA!! 🙌

Yes they will have a small module for xlite just not as powerful I’d expect and only one antenna vs two.

SiN FPV 711313101S , bomb squad comes running in with a couple of dozen armed swat team, nothing to see.

Fair point. But one of the specific benefits of 2.4 GHz is smaller and more durable antennas. I never met somebody whose Immortal T was actually pristine. Not after a few flights. So maybe the test is more realistic than it seems.

@@JoshuaBardwell I must be OCD because my antennae are all pristine, regardless of wavelength (sounds suss for a KZfaq comment).

Also, these bends in the Immortal T will cost a lot of dbs.

hahaha

Same for me

TBS is already there? These are essentially equivalent systems if you're not trying to fly 30mi+. Crossfire uses LORA. Take a look at the RF chips they use some time if you want to learn what they actually have from a technical perspective.

@@mitchellroberts7954 CF don't use Lora under 100mw, GHOST do it at full range, in EU the 868mhz band power limit is 100mW, 25mW for telemetry, CF use LORA up 150mW. You can use GHOST with LORA, CF with LORA is illegal in EU, somebody is selling you a bike, TBS just miss inform you and you can get a £5000 fine is you. TBS has good gear and is selling you smoke, because you are not allowed to use it,shit of company, that's it. SO GHOST in legal conditions, has lora, more range, more penetration, less latency, less price in receivers and modules,less interference, more range of telemetry. That's is, TBS=Smoke

He's getting in some cardio

@Russell Phelan Yes it's great 👍 😀. The Tango 2 is only 500mW on next V3 revision board. Trappy updated the radio on the new micro to compete with R9.

Change Agent it’s not 1000mW

Change Agent tango2 v3 PCB has EXACT same interanals as micro tx v2

You should fire up the rf explorer before the test to compare noise levels in the hotel. With all those WiFi and Bluetooth signals going on, ghost had to fight a lot harder

@@mhoovair89 m.kzfaq.info/get/bejne/rKeFg6-gksyqk58.html lol 😆 It sure is. Please research before correcting people to save embarrassment. Not being a jerk just saying. 👍 Edit: Hoov deleted a comment above with a false correction.

He is going to need a FlySky Paladin or NV14 to properly review it. Outside of those radios you will have to run the module in PPM mode. So no telemetry like LQ or RSSI. Hopefully FlySky and the OpenTx devs will change this.

TBS isn't a giant gorilla lol they're tiny. Going after a giant gorilla would be going after FrSky.

@@mitchellroberts7954 IN THIS INDUSTRY... TBS is a big player in our hobbies industry. and frsky? well, nope.. tbs sells more stuff than frsky.. tbs has: transmitters, receivers transmitter modules, antennas, planes etc etc etc etc.. frsky? transmitters (in which, in the fpv world, are tbs products shoved in the jr bay...) modules and receivers... ow.. and a small selection of antennas.. btw. i do not own a single tbs product, all my control link is frsky (QX7, R9, R9mm, r-xsr and xm+) i am no tbs fanboy, i hate trappy, but truth need to be told..

Truth is when you show numbers otherwise is just opinion

@@DutchCommando Of course this depends on your definition of "giant" but I've never seen someone call a company giant due to the number of their products, it's based on gross sales. Well, I've never seen it until your comment. I'd be surprised if TBS gross sales are more than $2m per year. FrSky is likely closer to $100m but like Robert said, until someone posts actual numbers it's just opinion. Edit: FrSky annual sales per their website are around $15mil for 2018. Seems low to me. "FrSky owns more than 4000 square meters of office area, about 8500 square meters of production plant with high-end R&D and production equipment, and staffs over 180 employees in its 9 years of development. Facing the severe situation of international trade, the annual sales of the 2018 year reached 105 million in RMB Yuan." Do you really think TBS has anywhere near 180 employees and 12,500 meters^2 of infrastructure?

Realistically, the link needs to be able to perform in WiFi saturated areas.

@@JoshuaBardwell yes, ghost should perform in 2.4 saturated areas, but a hotel is over saturated on 2.4... and has almost no 900mhz interference.. put the 900 system in an over saturated 900mhz environment to compare apples with apples.. but still, the ghost performs very, VERY well in this very difficult scenario.

Reflexion is not related to penetration. Reflexion of both systems won't be that different.

@@BlackPixxelDE Reflection is extremely different at different wavelenghts. Any conductive part of a surface larger than 6cm will reflect 2.4GHz, whereas crossfire requires almost 20cm. You can probably imagine that this means MUCH more reflections at 2.4GHz.

This is true, but a larger surface will not reflect both wavelength too differently. I just didn't want people to think that bad penetration = higher reflection

@@BlackPixxelDE That doesnt change the fact that 2.4GHz will get much more reflections. On long range connections this is a disadvantage, but in bandos it allows you to get reception in places that would otherwise be shielded, as the signal reflects and spreads throughout the building

Long range and ghost should not be used in the same sentence

You'd be surprised how much of the 900mhz band is used in big cities like that.

But unless you're in a certain place, that's a problem that could happen more or less anywhere. Nonetheless, though, it's too much of a test to fly with Mavic bundled in, for example.

Would like to see that from Painless360

I'll test it 20 miles out if someone wants to let me borrow one lol Bardwell isn't the guy who will do a 30 mile range test - just not his area of expertise.

valid point! i think for long range first the wing guys must prove if ghost is up to the task before putting it on a LR quad. a wing will happily fly back home at a fail save, and can fly ten times further than a quad.. long range is only thoroughly tested with planes.. also some serious long range guys use 2.4 video link, which renders ghost useless.. (they can swap for 1,3 video though)

Yes

ThomasB FPV no I was waiting for him to rip a few packs in there too 🤣

You have no reason to buy into ghosts. With crossfire you are golden👌

Like someone threw a rattlesnake into the chimp cage!! 😂😂😂

The video transmitters weren't the same in the two quads. Just wanted to give a general sense of how far the video went.

4x the power. Not 8x.

@@JoshuaBardwell Or say 4x power goes only 1.75 x the distance because you need a better antenna. 😄😃

I don't really know what you mean. Based on the inverse square law, 4x power gives 2x range.

@@JoshuaBardwell Backing away from a steady radio source the measured strength of the signal will be ¼ as strong twice as far away . But to transmit twice as far at the same strength a transmitter needs 8 times the power because the fiekd is getting bigger in 3 dimensions . Up down forward backward left right . Every direction . So to transmit twice as far takes 8 x power . And to transmit 3 times as far and recieve the same signal strength takes 27x power . If you failsafe a 25mW vtx at 100 feet , then a 200mW vtx will failsafe at 200 feet .

I'm sorry that's just not true. The inverse square law already takes into account the 3D spherical expansion of the wavefront. That's why it's inverse square and not linear. 2x the range requires 4x the power. Feel free to test this yourself using the RF Link Range calculator at this URL: www.immersionrc.com/rf-calculators/ Estimate Range and then notice that you must increase power by 6 dB (4x the power) to get double the range.
