Just took the plunge for an indoor quad on the Mob6... I missed out last winter as they were sold out. This year I’m early enough and I’m looking forward to upgrading to JESC. Thanks for you videos!
Very interesting - nice and simple. great to see just one change at a time and see what happens, thanks. Looking at the take off footage I think the JESC needed about 45% throttle where BlHeli_S needed closer to 50% not sure if that was my imagination or not? Looking forward to seeing if rpm filtering works better still. Mobula6 seems a good test platform as you can test back to back with no external influences like wind!! :-)
The throttle on the Mob6 is especially sensitive, so I'm not sure I trust the percentage, but if you can notice it consistently then it's probably true. What I saw on the video I linked to where I compare all 4 flights is it would just have 0.1v extra most of the time - which does translate into a good 30 secs or so. I think I have to move to different firmware again to put rpm filtering on, but still easy to compare against
Did this a few weeks ago on a trashcan. Coupled with Emuflight it flies great now and the flight time has doubled. Utter no brainer. I also did the same with a 4" quad, flight time hasn't improved but it's motors sound way smoother.
CurryKitten the latest version is actually working now. In the first release the Q and W filters weren't working at all. It also has a few preset tunes built into the PIDs tab. The beta 75 tune works great with the Trashcan. Give them both a shot on the Trashcan (if you still have it) and if you have time. I think you'll be impressed.
Same here with my mobula7! I went from 3 minute flight times on 1S to about 4 minutes. And then I put on 3 blade props and got a little more time on top of that too.
Best tutorial yet for flashing jesc! Quick question, if for some reason the jesc doesn’t work well for me, could I restore the original BLHeli_S settings from the BLHeli configuration? Thanks!!
We've tested JESC on 3 stock Trashcan's.. LiHv used: 1S 450 mAh.. 30 seconds hovering NO JESC = 48 mAh With JESC 32 mAh So exactly 33% less 3 x 16 = 16 / 32 / 48 mAh Flying time increased from 3 min medium flying to 4:30 min 🔥 Also motors are a waaay cooler now ❄
I flashed JESC and got the exact same 3:40 - 3:50 flight times as on the original BLHeli. That's on 300mAh cells from fully charged until it dead drops from the air (indoors hovering) Maybe it doesn't work for everyone 😥 I checked in betaflight mine is set up with DSHOT300. Should I try DSHOT600?
There's been a few people that have reported missing an ESC after the flashing (having looked through the issues that were outstanding) but the overwhelming majority of people were singing it's praises. There's always an element of risk when you flash something, but I felt it was worth it.
When I flash it with jesc for some reason it just flips out, and when I reflash blheli I have to reconfigure in Betaflight to make it fly normal cuz it’ll just flip out still, how can I fix this, I really need more flightitme...
First thought that comes to mind is are the motor direction in beta flight and JESC the same, it comes reversed and needs to be set as such in both softwares.
The question of what quads can be upgraded seem to be down entirely to the firmware they run on their ESCs currently, so hopefully a whole bunch can be :)
I just a/b tested blheli-s 16.7 24khz and jesc 2.2 48khz in a hover test with my babytooth (1202.5 11500kv on 1s) and got 7:05 and 8:25 respectively. Which works out to a 19% increase in flight time/efficiency. I haven't flown any packs full acro yet, but if there aren't any real downsides, I'm completely astonished at the improvement. Motor temps seemed identical, slightly above ambient, but as said, just a hover test. Either way, I think its worth a shot for anyone flying whoops or micro/toothpick style 3"ers. Just crazy how much extra flight time I got.
@@CurryKitten Definitely worth trying. Just flew a couple packs pretty hard full acro and it flew a little "loose" but pretty well altogether. It's also gusting 15mph where I live, which is less than ideal for a 60g auw, but im definitely not changing back until I fly on a really calm day and see how she does. Crazy af to get 6:30-7:00 out of a pack when flying at a pretty good tilt.
Upped my I gain about 10 points and upped my feed forward from 0 to 10 and shes flying just how I like. Flew 4 packs pretty hard and averaged 6:38, which is just crazy
@@verofpv6152 It definitely flew a little loose feeling, but yup, upping the I gain and then adding a little feed forward got it feeling normal and good again. I then switched from tri blades to bi blades and its flying way better now than it ever has and i'm averaging like 6:30 flying pretty damn hard.

Hello, Very helpful JESC review, thanks. Can you tell me which Mobula6 version's are you using ? 19K ?
How are you getting no voltage sag? Mine sags from 3.9 to 3.5 just from takeoff.What battery are you using? I get about 2:30 minutes draining from 3.9v to 3v keeping the throttle less than half the whole time.(with the jesc flashed)Odly with the stock usb charger. Itll charge to 3.9v and at high voltage itll charge at 3.9. But i notice the c rating on high voltage does change to 60. I dont have a jst ph 2 tester so i only have the mobula 6s' voltage reader built in for osd to tell voltage. However even of i need to chage the value in betaflight for the correct readout of battery but it should still increase right from regular 4.2 to high voltage 4.3. So why would it show that regardless they show 3.9v?
That might be an interesting test, as I rate the Nazgul5 very highly already and would generally think that it doesn't need anything more to make it smoother. SO a question of will RPM filtering make an already great quad even better ?
Cappurnikus I’ve got my nazgul on rpm filter and it’s amazing. Getting 15-20 seconds more flight time and it is actually more powerful. I find that I have more torque because the motors are quite high kv.
1:30 v3.5? Dude. You gotta get beta flight 4.1 and bidirectional dshot / rpm filtering setup on this thing. It flies so amazing. Locked in. If you don’t want pay for dshot then use JazzMavericks.
I saw a few issues about losing an ESC after a flash (did you open one of them, I saw one for a mob7?) It would obviously be useful to understand exactly why this happened and what the fix is. I hope the dev gets to it soon! Are you able to bring them back with regular BLHeli_S firmware or anything ?
i torture my fixed wing 3s lipos every time i fly and always take them down to 9v and sometimes when i screw up my power needed to get home ive been hitting 8.7 and waiting for the esc to cut out lol, ive always seen lipos as a consumable and treat them very badly :/ on my 450 quad i quickly found out that i have to land at 10v as it does not take much to cause a low enough sag to make it loose control and spin out the sky if i take it lower than that in anything but a plain hover
I murdered my old 3s 2200s to such an extent that a lipo plugged in showing 12.6 would go to 9v just on a wing launch :D You'll always be able to push fixed wing a bit more, the air is doing a reasonable job keeping the plane up there, while a quads ability to glide is quite poor :)
@@CurryKitten lol, I do a lot of gliding, I have a habit of climbing to high altitudes and quite far out and flying till my pack is dead and gliding for like a mile+ ha ha. Have you seen the qczek lora project? Its a firmware to turn 433mhz 1w UART lora modules into a Jr bay transmitter and aircraft RX outputting ppm. People have had very long ranges out of them (40 miles if i remember correctly) and two e32 lora modules can be had for like £11 on aliexpress. £11 for a long range system is crazy cheap!
I did that on my tinyhawk and 2 esc are gone... Now they show up as ESC 2: ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ (16.77), ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ and I can't flash anything on them, someone could help me please??
There are a few instances of ESC's going wonky using the JESC configurator. try opening up an issue on the project page. github.com/jflight-public/jesc-configurator/issues It looks like there's a log file you can provide to help diagnose the problem
I can't say I noticed any differences in the way it handled using JESC (although I was inside, so no breeze or anything to cope with) but I liked the extra flight time :)
Everyone talks about the flight time but no one ever mentions the loss of control to some who just Cruz you won’t notice but once you start racing high speeds or doing lots of freestyle you notice and it’s crap stick with 24 of your a avid pilot 30 seconds isn’t worth the slop
I used it on my tinyhawk 2 and it improved the flights time. I use the pay version and 4.1 BF not sure that matters. $5 is reasonable and the rpm filters seem to help.
Yep - correct me if I'm wrong. They come up with very nice tunes for micro/whoops - mostly the RTF variety. I've never used one (yet) but I'd like to try. I didn't know about them until people started mentioning PMB to me in the comments a while ago.

Hi ya, I have reversed motors on my king kong ET115 v2 will this be ok, I have checked that it is (h) when I hit read setup motors are showing reversed. I know it seems obvious but just wanted to check if anyone has hade any problems running reversed direction. Thanks
Yep - its fine. Brushless motors don't have a direction they want to go in (with the exception being the ones with nuts that thread in a certain direction - but that's just to keep the props on) which way they run is completely dependant on the connection order of the 3 wires that attach to the ESC, so "reverse" means spin the other way from the connection. In the "olden days" we had to desolder two of the motor wires and swap them over to reverse the motor that way

Every second more counts!
Especially in these tiny quads - nice to get that little bit more :)
hello CurryKitten, thank you for all the support and info you share with us.
No problem, I hope it was useful
@@CurryKitten you
Excellent bit of info. Thanks so much!
Hello, very simple and helpful guide to flash JESC to 48khz, easiest guide so far. Thanks!!
Cool - hope your quad is flying for longer if you've done the flash
@@CurryKitten for now it flies a little longer and I'm very happy that I didn't broke it :))
Thank you very much for this video!
Nice comparison. I use JESC and 4.1 on all my drones now. Using RPM filters seem to flight very nice.

30 seconds hovering NO JESC = 48 mAh
With JESC 32 mAh
So exactly 33% less
3 x 16 = 16 / 32 / 48 mAh
Flying time increased from 3 min medium flying to 4:30 min 🔥
Also motors are a waaay cooler now ❄
Nice - I've a bunch more quads I'll do this on
@@CurryKitten my 2 FPV friends flying it now on JESC couldn`t believe it :D They were so hyped about it !
I flashed JESC and got the exact same 3:40 - 3:50 flight times as on the original BLHeli.
That's on 300mAh cells from fully charged until it dead drops from the air (indoors hovering)
Maybe it doesn't work for everyone 😥
I checked in betaflight mine is set up with DSHOT300. Should I try DSHOT600?
Interesting, thanks.
No problem :)
Thanks for this..probably going to try it out on a old trashcan that I won't ,miss too much if I brick the esc's somehow...

I've got the L Version ESC, so i guess im out of luck
Jazz Maverick BLHeli_S can do 48kHz even with L typ escs
JESC is free for L escs as well.
So any quad can be updated with jesc without needing bf 4.1?
Yes - as long as they run the right type of BlHeli_S firmware to begin with
