is this product compatible with pixhawk? and especially does the bec supply the 5v in order to keep the motors on running in case of a failure?

When is expected to re-stock in European or UK Warehouse ? It is realy annoying and frustrating that this ESC are permanently sold out in UK or European Warehouse. Same with 12 A item (Produkt ID: Tz12A).

Would these be good for a 450 quad ... flashed of course?

Yes, if the motor is also adjusted (a 26 or 28) - sorry but I do not get HK mail notices, so if you reply I will not get a message. I am no quad expert - only built one with this range of ESCs (although I bought the Afro, already flashed series), and it does fly.

Are these suitable size for a 250 class quad?
 Napstr 1190 points
Hi James These would work but would be a bit big and heavy really - you are wanting 10-12 amp controllers really to save some bulk and weight.

presi 2, perfetti.
ottimo regolatore al pari di quelli molto pi costosi, molto regolare l'accelerazione senza strappi o "buchi" a 20A continui con 3 celle risulta tiepido dopo 2 minuti.
perfetto, confermo 5 stelle
