im new at this but what I flash do we have to play around with these much to install them
 DR01D 85 points
It's not too difficult if you have done it before. Otherwise it may require you to play around a bit. There are some useful guides on Youtube.

Is it compatible with Naza M lite ? Does I have to disconnect any wire for that ? (I saw that on a forum but it doesn't work)
 teknokraze 186 points
Yes it works with Naza-M Lite. You do have to disconnect the red servo wire though as the Naza uses it's PMU for power and battery monitoring.

Anyone experienced brownouts with this esc? I put this esc in 3 planes now and all of them had brownouts. I guess I have a weak bec on mine.

You might want to consider using a standalone UBEC to supply your RX with 5V. Maybe something like the HKU5 - which i use and have never had a brownout.

I have reciever voltage telemetry and can say the voltage really sags when using servos, dropping to 4V after a few seconds of moving 4 servos simultaneously.

Consider the location of your aerial, keep it clear of carbon spars!

what is the max current of BEC?
 Finnius 267 points
It's rated to 3A but i personally wouldn't push it even that far, just to be on the safe side.

I put two of these in a Dynam A-10 with the stock 64mm 6 bladed edf's & a Turnigy P2627L EDF Outrunner 4200kv for 55/64mm with a turnigy 3000mAh 40c lipo. Esc's are giving out 34A at WOW & come down a little hot on hard flying but are doing the job and keeping the plane really low on weight. great price I love these blue babies, go for it. I will by buying more!!!
