Warning about CC 50amp LTE BEC with BK servos

[BP58]

After a bunch of tests I found that the bec in the Castle 50lte just can't handle the load of the bk3001 and what ever the matching tail servo is in my 450L. I got 3.3v warnings in my mini vbar with bec at 6v and at 8.4v on the bench and in my maiden at 6v.

A 20 amp bec did not give any low voltage warnings on the same bench test. Running 2 100uf 16v capacitors in parallel on the vbar also kept the 3.3v warnings from showing up only at 8.4v Castle 50lte bec. I'm ordering some 6800uf capacitors as suggested in the vbar forum to confidently fly.

Hope this helps one person from crashing after upgrading servos.
Just like hot rodding cars, there are no free horsepower.

Thats not surprising cuz the kst servos cause the same issues so seeing bk servos do this just makes sense. You can fix it w what your doing or just install a hw50 v3.
