Its BEC is linear ,or switching type?
 Bobo22 124 points
This one is Linear! 40A Blue Series and up have SBEC. You can look at the manual in the Files section. Cheers!

How important is the heat sink on the esc ? assuming the esc is sitting right under the prop....
 Bobo22 124 points
It absorbs and dissipates the heat, so it's pretty important. If you are thinking to run this ESC without heat sink, don't do it. You will fry your ESC regardless if it's under the prop or not.

Hello Dajaraja. Thank you for you response. It is the 550 model, and I haveTurnigy 3300mAh 3S 20C Lipo Pack, as well as a Turnigy nano-tech 3000mah 3S 25-50C Lipo Pack. The Motors are 35mm and came with the kit, and I don't see any identifying information on them at all. The Rotors are 10 inches diameter from tip to tip. Thanks, Ron

hi Ron,ok first of all I don't own a quadcopter(planes).but this is what you need to do for best pick esc.your motors specs= 930kv spinning 10.38 prop full throttle * 14.5 amp on a 3s lipo.on the net though, same setup others are posting 19amps and I didn't find anyone using your motor , prop and lipo ******* with watt meter and posting there PRODUCT ID: 031000046 for your motor,read reviews concerning your Motor, ESC, & Battery by RcHelpDotCom .google=How to choose ESC UBEC, BEC for Multicopters - OscarLiang****.you need a programmable esc thats 25 to 30 amps and 3s lipo compatible.i also don't know what control board you brought and this would have to be taken into consideration as well .but matching esc,motor,lipo and props are the most important things you need to learn for longevity of your you just need to find one that's the right size for space provided.also balance your props.please don't credit if Ive helped,happy to pass on what learnt from others:)

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!!!
