Hi Damien, They're fine for 2S-4S LiPos. Great quality ESC with some really good features such as auto-timing. Cheers, EA!

Hello...IF this HK blue series 30 amp ESC has a switching BEC.....then.....Please show us where it says SWITCHING bec.....okay? No where in the description does the word S-W-I-T-C-H-I-N-G appear. Please don't tell me SBEC......because all the good esc's spell it out.....S-W-I-T-C-H-I-N-G BEC. These blue series speed controls must have a LINEAR bec.......because they never make a point of printing the word S-W-I-T-C-H-I-N-G BEC. If I am wrong...please....CONVINCE do you know? Just look at the YEP and other more expensive speed controls and separate BEC's. They always say SWITCHING bec. HOW DO YOU KNOW? I have two blue series 30 amp speed controls. The instruction manual does not say which type of BEC........why not? This is important to know. Why won't they tell us?

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!!!
