Josh, could you do a video about the opposite end of the spectrum: how to build and tune for the most efficient quad possible? I'd like to see what you would choose for a super long flight 5 in and 7 in build.

@PhantomFPV Год назад

Awe yeah!!! Running the old beast. Glad the ESC held up. Some sick stuff and thank you for the shout out JB! Much love big dawg!

@calif94577 Год назад

Id argue that the props flattening out was making it easier on the ESC since they were not biting the air as much on the top end there. Retry with stiffer props 😂

@ersetzbar. Год назад

funny, my first idea was, that you would need steeper props for these speeds

@yohfpv Год назад

@@ersetzbar. Haha I don't think that same lipo would survive it. The poor thing was crying. Might need a beefier battery for that!

I like this kind of content a lot. It's unrelated to FPV "current events", new releases, blah blah blah. Just good old experimentation and crazy fun.

@gabruzz Год назад

I have a Skystars KM45 esc and as far as i can tell this is one of the durable esc i have. I mounted it in my race rig and after several (hard) crashes I count more burnt motor than esc damage. I bought 2 more of their esc hoping are as durable as the first one.

5:38 - Instead of USB power for the GPS, get a ViFly GPS Mate. It functions as a powered buzzer and powers the GPS before the fix and between LIPOs. It's easier and more functional than a USB power bank.

@JerryDSM Год назад

My first mini quad was a 2400kv emax hawk pro. I ran 6s on it for like half a year. No issues with it at all. Was super impressed when I learned that I wasn’t supposed to do that 😬.

@joshuasterling2144 Год назад

LOL, one of the things that saves you is its not a static load. If you did it on the ground without a dynamic change in load you might have had some toasted components..lol Good times. I bet it was fast.

Fantastic flying, Joshua! 😃 Pretty interesting stack indeed! About the Gemfan props, the force is strong in their family. They didn't break even after crashing. 😬 Anyway, stay safe there with your family! 🖖😊

@JoshuaBardwell Год назад

Nahhh I'm not a fan of the durability of the F4 props. The bend and crease really easily and don't flex.

@ChainsawFPV Год назад

We did this a couple years ago. I actually built the same quad after your video. The Luminier F7 and Tmotor ESC with 2800kv motors on 6s. Still have the parts from it.

@davet2563 Год назад

Been buying these ESCs for a while, they are good, and they were cheap. I think I got my first one (45A) for ~$28. Those days are long gone.

@TopCrinkly68 Год назад

Well! That was fun!!

@shadofpv Год назад

Also depends upon the weight of the quad compared to what it was before with the pid's, especially with high power to weight quads, the pid's can really vary a lot, normally an amount of TPA such as 70% at 1700 can be applied to smooth out that wobbling caused by the pids at top end of throttle ;)

Extra likes 👍 for the sound effects @ 10:58

@princesfpvdrones Год назад

The ONLY way I found mine to go that fast with your exact set up was using carbon by-blades, other wise the tri blades set up just drew too many amps causing the quad to flip out. The settings I had to work with was not so much pids or filters but the setting in the esc, ramp up and such but in the end I was successful, the video is on my channel. Hope that helps.

@joshuasterling2144 Год назад

Carbon blades are insane. I only had one pair back in the day but what a difference in characteristics.

@joshuasterling2144 Год назад

I don't know if you guys ever had the chance to fly the Diatone R349 but it was telekinetic. It was about 35mph down from this quad but the absolute power to weight ratio made it directly connected to your wishes.. It also pulled down 90+ amps on a three inch...lol

@michaelwilkes0 Год назад

Yay that answers an unsolved mystery of mine. My quad freaked out upon takeoff just like that, but not on betaflight 3.5, only when i updated to 4.3. I guess my quad was too powerful for betaflight 4.3 defaults. On that note, I have never gotten 4.3 to fly as well as 3.5, which is kind of a bummer. I tried downgrading but 3.5 but it isnt in the software list anymore. I could probably find it on the web somewhere but its just that extra bit of hassle. I kind of wish they just left old versions in the configurator longer, but i know thats a hassle for them because the gui doesnt work with versions that old.

@AtradiesInc Год назад

Can you show a setup on this board? My elrs stops binding when i solder in the caddx vista

@Romasu_ Год назад

I really wish my first product with skywtar wasn't a total bunk. Didn't even have the motors wired up. Just made sure everything was good with the esc to fc. With a smoke stopper. And an esc on the underside of the ESC just blew up

Hi! Awesome video Can you run a 50V 470uF capacitor on this kind of setup? I can’t seem to fit the 50V 1000uF on 😢

@AerialWaviator Год назад

Regarding 21:55 ... if you even thinking about doing it, go for 163.5+ mph and claim a Genius World Record. A good number to aim for would be 186+ mph .. .300+ km/h. Can then brag you're a speed demon and broke 300 baby! ♥🏁💨 Maybe there even an indoor sport/track stadium that would think it fun to claim to be home base to a GWR.

@jonnyt9895 Год назад

I have a problem: the motors when idling vibrate and make a rough sound that fades as speed increases (both with and without propellers mounted). I bought mini F722 HD Pro AM32 ESC Stack 2022 version and I'm using it with 2806.5 1300kv I'm using Betaflight 4.4 and checked that all 4 motors spin in the correct direction (if I use Betaflight for spin the motors they suond smooth) Can someone help me please?

@ah4quadssake885 Год назад

I asked JB on his livestream about skystar stacks several times due to them being so cheap.I have my answer if its on a 160mph quad 👍

@dfourmed Год назад

They got a bit of a bad rep early on. They've come an incredibly long way since. The F7s and H7s are the only FCs I'll buy now!

@mode2fpv Год назад

so for video on all the time you have to bridge VON pad or just leave it as is ?

@joshuabardwell thats weird I had 2208s 2450kv on 6s....and with a good esc and FC I didn't even have to tune it for it to fly decently.... it was a freestyle frame... good esc was fine but it did ignite a cheap tmotor esc doing a split s....

Just fitted some new Pacer III v2 2306 1950kv motors on my previously 2306 2450kv hypetrain rig and my f7 Mamba 50a stack is freaking out am getting mid throttle flyaway at take-off. What would I do to fix this I've reset everything to stock latest firmware target and esc updated to latest firmware but still the mid throttle madness continues to plague me. Any help would be muchly appreciated 🙏

@R.B_B 9 месяцев назад

The real question for me is about the propellers. What type/model of props can handle that speed efficiently

@lililililililili8667 Год назад

Think that new speedybee v3 stack could handle a 4s motors on 6s?

@originafreerangechicken Год назад

Affiliate link, Joshua? I don’t see it? Picked up a couple of the full size F7 HD stacks a while back when they were cheap. I’ve had good luck with the one I put on a basher quad. 50ish packs in with no issues. Average sessions, nothing extreme. Not a lot but it’s a sample.

@JoshuaBardwell Год назад

Geez how did that not get saved! I've added it now thanks for pointing it out.

@BikeGuyFPV Год назад

Maybe try a 20x20 ESC that has full sized MOSFETs? The Foxeer Reaper 60 and the Reaper 60 Slim are two that come to mind. ESCs that have the small MOSFETs usually can't hold up for long when being put under a lot of abuse.

@JoshuaBardwell Год назад

Yes! I agree. This one won't be as durable as the Reaper.

@Fleche_FPV 11 месяцев назад

I have the same problem on "classic" motor in 1800kv in 6S... I think that we have to decrease startup power like as rampup power....

@AngryD3v Год назад

Just curious what variant of the Skystars ESC was used for this experiment (or does AM32 only come in the one 55A size)? My "build" (BNF) with the KO45a ESC and 1700kv motors turned into a fireball after a relatively minor crash (other builds survived worse crashes)

@JoshuaBardwell Год назад

It's the 55a one.

@as1asim Год назад

Hey there JB,first of all love to watch ur vids.Actually m new to this hobbie,and i need a suggestion,m building a quadcopter and the issue is i got mamba mk3 stack which has only 5v bec out and the Vtx i got is an Akk Raceranger which requires 1600mw power,so the question is should i got for an individual 12v BEC or a Normal 2/3A 9-12v stepdown voltage regulator?Thnkx

@RD5500 Год назад

Im running the mamba f722 mini mk3 and akk fx2 ultimate mini, i just use the vbat pad from the fc to run the vtx. Not a single problem to this day besides noise as i havent installed a capacitor on the esc. If u just add a capacitor to the xt60 or the esc power pad i bet it would eliminate most of the noise.

You can only change the Bluejay PWM frequency by flashing the ESC.

@matthewmaxwell-burton4549 10 месяцев назад

Sensored motors would be for FOC, although nowadays you can use estimators without a hitch. Just at 0 rpm you need to jog the motor cus the controller doesn't know the position.

@JoshuaBardwell 10 месяцев назад

Sensored motors are not just for FOC. They are often used in ground vehicles where you need torque at low RPM.

@matthewmaxwell-burton4549 10 месяцев назад

@@JoshuaBardwell if it’s not a servo, you can’t get 100 torque a low rpm with synchronous motors. An inherent trait. Unless you use a vector control based system you have no finite control over torque as it is still coupled to flux thus speed. Moreover the motor is unstable till you reach the steady state rpm. I went a bit off topic but that’s why I’d love to see foc on drones. Part of my degree was control theory and motor control. When I hear PID I shudder when I hear pid, as the running gag is pid is the poor man’s choice and is never the solution (pid is only optimal with 0 delay, which isn’t possible) in our case sensorless is absolutely fine, if an arduino can do it… anyhow thanks for your insight, love your content btw

@Marco92Z07 Год назад

It has a BMI 270 gyro, so of course you had to get different (or stronger) filtering options than with the old 30x30 stack wich had the mpu 6000, I guess.

@mr_pike4609 Год назад

I've been comparing mpu6000 and bmi 270 for a while now. It's pretty much the same. I even have a mpu 6000 fc which actually needs more filtering than my other parts.

@JoshuaBardwell Год назад

That shouldn't be true in BF 4.3. It changes the internal hardware low pass in the BMI gyro to be similar to the ICM and MPU gyros.
