    And I thought that beer and sex does that....
    If you're a noob, copy 1:1 what somebody already flies without too much questions, you'll find the answers later.

    you are flying it LOS... You are doing it wrong.

    Regarding 6S HV and BECs. Keep in mind that regenerative braking might boost up your voltage even higher. I measured 46V peaks at 5S. And I also killed some 6S capable BECs on 5S due to spikes.
    Also I would build a test rig with all electronics first before you cram the stuff into the frame. Experience speaking here .

    This is true but quality yes he's that have regenerative braking should have already known these things and use the components able to deal with such spikes.
    Also using caps on main power and at escs never hurts on beastly builds.
    I myself build and fly only high powered ,5-6in builds aimed at speed as priority one and yet to have any ESC or FC or bec blow from using its recommended voltage amd even over voltage luckily.
    Aome builds have caps only on main lead and some on ESCS too as well as no caps on some and I run us on all 10 quads I have and all with high kv (2400kv-2700 2207,2408,2507,2210 and whatever largest most powerful motors out there)
    I found, Ak32 4in1 AIKON, actually takes 6s high kv, with any 5in and 5.5in prop and also all 6in ive tried,rather easily and yet to have one blow with braking and using its 5v reg. Pack after pack in Florida summer temps .
    Also spedix 30a hv are yet to fail with everything ive thrown at em along with 4500kv 2205 on 4s full throttle pulling over 220a while around 3/4 throttle.
    I know the AIKON are actually rated at 40v as well as Matek F405 ctr aio also rated around there so with caps even us should be no problem and likely 8s..
    Ive seen the impulserc helix FC/PDB run 2300kv 2205 on 8s successfully and have one here just Havnt tried yet.
    But if anyone is looking for 6s ESCS that take high kv torture flight after flight then get spedix 30a hv individual ESCS or AIKON 4in1 ak32 and matek f405 ctr aio for pdb FC and radix for non pdb.
    Also if wanting 8s or 12s powerhouse escs check out APDF3 ESCS .
