Very very interesting. Personally I can tell the slight difference between crsf and frsky so this sounds like it will definitely be a difference.

[@BrandonBeans]

Why you gotta go blow our secret?! J/k redpine is awesome. You lose 3 position switching, but that's the price you gotta pay for FAST. Also, one may want to consider retuning feed-forward, because it's common to need less due to the faster response.

[@AlbertKimTV]

Ah, good tip on feed forward... more secrets are out!

[@mrdad_fpv473]

Very interesting. Thank you for making the video

[@pauljaggers402]

Is ELRS an SPI receiver? Just wondering if I can flash RedPine instead of ELRS.

[@AlbertKimTV]

Redpin only works with Frsky SPI receivers, not ELRS. FYI, ELRS is just as fast and better overall. Redpine would be a downgrade.

[@MCsCreations]

That's pretty interesting, Albert! 😃 Did you noticed any range difference? Stay safe there! 🖖😊

[@AlbertKimTV]

Not for racing inside my house. If your whoop race track is a mile away, I suspect this is not gonna be for you. LOL..

[@JyeSmith]

FYI a packet rate this high currently useless on the Tango2. External modules are only receiving packet updates at 50Hz. github.com/tbs-fpv/freedomtx/issues/12

[@whimpydogfpv8663]

Any idea which deviation firmware supports redpine or who to contact to find out? My jumper doesn't have redpine as an option.

[@AlbertKimTV]

Check the links for the RCgroups and github in the description for more information. Also www.deviationtx.com/

[@whimpydogfpv8663]

@@AlbertKimTV I'll check that out thanks!

[@pksteffen]

Very cool and nice multiprotocol radio!!

[@AlbertKimTV]

Thanks!

[@djs134]

Hmm, I have a 2 mobula boards and a tango 2 with the mpm module and i can’t get it to show in betaflight Receiver page . I’ve changed to redpine on in betaflight created a new model on my tango 2 set to redpine fast and use the cli commad to bind_rx but no rx movement on the betaflight rx page

[@AlbertKimTV]

You need to upgrade the MPM to the latest firmware version.

[@pauljaggers402]

Will this work on BetaFPV 65pro?

[@AlbertKimTV]

It will on the Frsky version, not the ELRS version.

[@ferb7452]

Well this will be interesting

[@Jahoosapheth]

So you got the xjt module to work on the tango 2?? I thought that it doesn't work due to an extra pin or something. I canceled my order of an xjt cause everyone said it didn't work.....

[@AlbertKimTV]

I haven't tried it. I'm using a multirprotocol module and it works fantastic.

[@Jahoosapheth]

@@AlbertKimTV my bad I had to watch it again and noticed u have irangex not xjt. Xjt module is confirmed not to work. I guess the irangex does tho. Thanks for sharing btw the rest of the video was interesting I just got distracted by the module haha 😄

[@BuddsSkyCam]

Will this work with spectrum spi?

[@AlbertKimTV]

FrSky only

[@beechFPV]

Interesting. But what’s the buzzing.

[@AlbertKimTV]

some noise from outside the house...

[@pacificnorthwestpilots6050]

Whoa, nice!

[@AGILISFPV]

Woah!

[@yoanariosuwandito8711]

i have jp4in1 module, what protocol is best for less latency?

[@AlbertKimTV]

Redpine

[@zfpv7211]

Definitely not 1-5ms from stick to motors. The filters alone typically induce more latency than that. But 1-5ms from stick to BF read is still insane. I find it kinda hard to believe lol

[@AlbertKimTV]

This is what the developer said on the rcgroups thread. "1-5ms from transmitter gimbal to betaflight dshot motor output".

[@zfpv7211]

Albert Kim Thats what makes me suspicious. There’s no way to estimate how much delay each individual filter setup will add. Not to mention, at 1-5ms, that would make the radio link basically instant.. which is physically impossible.

[@hulpe]

@@zfpv7211 possible with higher refresh rate /shorter signal width though ^^ miliseconds is quite much for signal paths in general

[@lrfpv5292]

I notice 1.5ms is 666Hz (as stated on github)...I would stay faaar away from this......... ... ... LOL

[@AlbertKimTV]

OMG 😈😈😈😈👹👿👿😈

[@lrfpv5292]

@@AlbertKimTV Haha are you a fellow believer?

[@Starche_fpv]

I think Bayang protocol is highly underestimated, sadly you did not mention it

[@AlbertKimTV]

I'm not sure how this is related since people will need a totally different FC and receiver to use that protocol. Also, most manufacturers of BNF whoops don't support that protocol at all nor make any BNF products other than some low-end brushed whoops from 2016.
