Very IMPORTANT for 75mm Whoops with high kv motors | AWG20 Main Cable

Hello my whoop friends! I can report something new about the VCI Spark 8028 27000kV motors: I have now changed the main cable from AWG22 to AWG20. And the voltage is now a little less and the flight time is significantly longer! I can now race around 2:30-2:45 minutes with the Dogcom 550mah 150C. And with the GNB 530mah 2:00-2:30min. However, the Voltage Sag is still strong for my taste. I wish the motors had less internal resistance.
The conclusion about these motors is: They are super responsive. But the voltage sag is a bit strong. With a 12A flight controller, AWG20 main cable, BT2.0 Plug, good lipos, they can still be flown well enough.
And the conclusion of the main cable is: AWG20 is definitely better for 75mm whoops with high kv motors. It somehow makes sense because the Lipos also come with AWG20 cable.
And I can report: The new Zenchansi Cam is actually PAL and not NTSC. But I only noticed the reduced frame rate in special lighting situations. I still think it's a very good cam because it has such a good picture. That's why I'm going to buy a few more of them...
But for crazy racers like neon fpv and tdog fpv the frame rate is too low. For the rest of the pilots, around 90% of them, it's ok in most situations in my opinion.
Happy whoopin my friends! Whoop whoop! :-)

Can't remember how I found your channel but I'm glad I did. Thanks.

[@butterflyfpv]

I`m glad to hear this!🤜🤛 Thank you my whoop friend!

15-30 seconds is actually pretty considerable given how fast those motors draw current - and will probably make those motors more viable for racing (though ti agree it still sags lots). Great flying as always fam!

[@butterflyfpv]

Exactly! Thank you my friend!

[@microdroneunderground]

Good info. Thanks for sharing. 😎

[@shalotfpv]

WOW, all my cables are AWG22-- never considered it might be a bottleneck. Smart! Good looking out and a wonderful flight

[@butterflyfpv]

I wasn't entirely sure until now either. But with this build I felt it very clearly now. And that's perhaps why my 75 802 27k build was so efficient, because I also used AWG20 there. From now on I will definitely only use AWG20 on high kv 75mm whoops. I suddenly started using AWG22 again because I no longer had AWG20 and I thought that the difference wasn't that big. But now I know it was a mistake.

Have you tried changing motor cables? Stock 28awg looks to be tiny in comparison with 20awg that you are suggesting here. Sure, there are 4 motors, but the cross section area difference is 6.4:1. 26AWG should be a perfect fit.

[@butterflyfpv]

No, but it`s a good idea! Thank you for the reminder! Today I saw that the VCI 08028 27k motor stock only has 30AWG! I will replace these with 26awg. Let's see whether this is an advantage like the AWG20 main cable or whether it is enough of an advantage over the weight penalty.

[@m3h0nk]

agree but I use tricolor cable which is a bit loud but it is very good and light

[@butterflyfpv]

Loud?

[@m3h0nk]

sorry my bad english @@butterflyfpv loud = hard

[@butterflyfpv]

@@m3h0nk hehe no problem. Yes the bigger cables are a little bit stiffer.

Wie immer sehr gut👍😊 kabel liegt hier schon rum nur noch einbauen😂 dankr für den test brauche ik es nicht ausprobiern sondern kann gleich los legen😊👍👍👍

[@butterflyfpv]

Sehr cool! Jetzt weiss ich auch wieder warum meine früheren high kv builds (die ich mal reparieren sollte) so gut und lange flogen. AWG20 ist wirklich ein muss für high kv builds.. Jetzt weiss ich es wieder xD

[@user-wt5hi1ep3d]

Habe es bei einer. Reperatur gestern gleich eingebaut Wat soll ik sagen😊 ich habe nur. 25 KV aber es funktioniert echt gut der copter fliegt viel smoother irgendwie besser auf Steuer befehle🎉🎉👍👍👍 nur das einlöten in mein HP x12 Board war ein bisschen fummelig🤪 super Tipp💯☺️👍👍👍

[@butterflyfpv]

@@user-wt5hi1ep3d Nice! Freut mich zu hören! Danke für das feedback! Sogar schon beim 802 25k. Das ist nice zu hören! Ja stimmt, das einlöten ist nervig. Vor allem weil die meisten boards nur löcher für 22AWG haben. Sprich mann muss beim 20AWG Kabel ein paar Litzen entfernen so dass ein teil des kabels ins Loch passt.. Ziemlich fummelig das ganze.. Aber wir sind uns ja rumfummeln gewöhnt von unseren whoops.. xD

[@user-wt5hi1ep3d]

bin aber nicht sicher ob jeder den Unterschied merkt bei harten manövern merkt man das die sind einfacher zu kontrollieren 😊 Power loops usw Ich habe die Litze verdreht und dann verzinnt Dann erst eingelötet Gehe davon aus daß es so dünner zum einfädeln ist😊

[@butterflyfpv]

@@user-wt5hi1ep3d Ich zuerst auch , aber mein AWG20 Kabel passte nicht durch die Löcher am x12 Board.. Bist du sicher dass du AWG20 verwendet hast?

[@tane388]

Video is really good bro! Seems like its better then razer pico nano, what do you think?

[@butterflyfpv]

Oh yes in my opinion for sure! It`s also a lighter cam. I hope they do a V2 of this cam with NTSC in the future..

[@tane388]

@@butterflyfpv I hope so🫡
