Would these be good for a 450 quad ... flashed of course?
 Richtofen 1273 points
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 1184 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.

Buddy code in the forum (international warehouse section). Good for around 12 more days!

Hi, Would these ESC work fine with their native firmware with Multistar motors 2206 and Naze32 FC ?
 georgiev.s 705 points
It will work fine, but it will work way better if you flash them with simonk firmware.

Yes. I need for this USBasp AVR Programming Device for ATMEL proccessors, that is out of stock. My computer is runnign W8.1 no problems?
 georgiev.s 705 points
I used the USBasp for flashing mines, but you cal also use this one: PRODUCT ID: 332000007 It is a bit expensice, but a way easier to do. W8.1 should not be a problem, I do it on my W7. Thanks for the credit.

Can anyone comment on HK back order performance for this item? How long did you have to wait for it?
 Bobo22 6 points
Well, I can reply to my own question now. After I backordered this item it took a little over 1 week for it to come back in stock. Thanks HK!

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
