BE AWARE! this is a great video. However, Ive burned two T-Motor 2550kv and one ESC by doing this. The cables inside the motors melted down after a few packs creating resistance and overheating the motors. Check your motors every time you finish a pack. If it’s too hot continue lowering the output limit or you could try tuning your quad better. *Like this comment so other people become aware.*

Can you elaborate how it happened? did the trick worked or did you overpushed your motors like 2550kv to 1900kv 6s? you ve said "after few packs" so I understand that it doesnt burn it right away. Am I correct?

it s probably not the power out but the PIDs. The D is way to high for 4s. The PIDs bypass the motor output limit/scale . Please tell us if you had any luck :)

@@zafosinferno888 Well after seeing this post I have asked this at Betaflight Slack channel. Some people replied that they had no issues . I am copying Tehllama42 's reply here : " I have about 13 quads on remapped motors that all run 6S with motor KV above 2000KV, so if it flies on 4S, you will be fine on 6S (but highly recommend building a 6S PID tune with less master slider, and throttle limiting)" and "you'll probably be fine with dropping the master slider two ticks, and starting off with the throttle limit around 72% at the motors (and if you like limiting from the transmitter, running 67% there). That bit of extra overhead is for the PID controller to use." I am going to take these advices and start PID tuning from there.. That being said currently I have no 6s battery and need to order one.. And I am thinking that zafosinferno888 guy might have used Drainman's magic numbers but his KV is higher. That might be the reason afterall

@gamaxgbg5 жыл бұрын
Well, actually it is not totally true because when you do this you have a motor that is not working at 100%. Unfortunately when you divide the output by the "magic number" you're not actually dividing the battery voltage that goes to the motor but you're only making that voltage be active an x% it would normally be. What does that mean? It means that the current peak that passes through the wires is the same as if it wasn't limited, even though the average is lower. So in the end you have less efficiency because you have more high-current losses and because of the higher peak you stress more the battery (even though flight-time is the same because the average current is the same). So it is a lot closer to using a 4s setup with a 4s battery than it is to using a 6s common setup. But considering it is a lot more practical and you can make it a lot more powerful than any of the above because you can always increase the "magic number", this is a very nice option to go if you don't have many builds and batteries. Approved!

I get why some would want to do this, but I don't think it is worth the effort. If you want to run anywhere from 2-6s batteries on a quad, you simply need to get motors rated for 6s and put them on your quad. Then it will automatically function with varying levels of aggressiveness depending on the voltage of battery you installed. Most flight controllers and esc's can handle 6s these days(check yours to make sure). So its a no brainer to just get lower kv motors that can handle 6s. The exception to this is if you are fully committed to using 4s batteries. Then you will benefit from more power and flight time with 2200-2800 kv motors
@stream.yoga.meditation3 жыл бұрын

Why not simply use a lower pitch props on the 24-2500kv motors for lower amp draw with 6s? Or do both, run 6s on a 5x4.3 or similar (instead of a 5x5x3) and set the profile for around 90%, so that full 6s rpm is available for a crisp tune on profile 2. What about FC headroom where it commands more throttle than the stick for control? Will it exceed the 72%?
@DrainManFPV5 жыл бұрын
Yep that's the beauty in FPV you can do it however you want! This is just another way to do it. If you use lower pitched props it's not going to change the rpm. Limiting your output will allow you to actually change the rpm's. The other cool thing with this way is from 4s packs to 6s packs your tune will feel different, with the auto profile it allows you to run different PIDs and Rates per profile, which change automatically when it reads your battery's voltage.
@dash84655 жыл бұрын
@@DrainManFPV Honestly, really great tutorial.. good on ya, and sub'd. A lower pitch prop will absolutely turn higher rpms at a specific input voltage while drawing fewer amps compared to a higher pitch prop on the same motor and voltage input. The higher rpm allows a bit more fidelity and responsiveness to fc commands, a lower pitch will also spin up quicker with less amp spiking. Lower pitch also tends to be a bit more efficient in terms of static thrust per amp (less cavitation, which also aids tuning). My advice and perspective is to address a mechanical problem (excessive Kv) with a mechanical solution first (lower pitch) as best possible, then clean it up with electronics. As a follow-on video, it would be real intersting to see you put the 5x4.3 and ~90% approach to the test.
