Here's an ESC for those that like to push their equipment a little - hotliner pilot's this means you!

The Hobbyking 70amp ESC is Opto-isolated from the receiver, meaning that it has no internal UBEC to power your receiver and servos.

Historically, you would need to purchase either an external UBEC or a separate receiver battery to complete your power system when utilising an Opto-coupled ESC.

Not any more - We have an all in one solution!
This ESC is supplied with a pre-wired 5amp external UBEC, not just any UBEC, this is jumper adjustable to provide 5, 5.5 or 6 volt output to your radio equipment. The UBEC is wired directly to the battery input cables to the ESC.

This arrangement will add a margin of safety to high powered (or highly strung) models. In the event that the ESC was to fail, the receiver and servos will remain powered and the pilot should be able to land his model safety.

The only incident this system won't safeguard you against is Lipo cell failure - Always be sure your Lipo's are up to the task at hand and that you are drawing less than their rated 'C' current.

I'm using this in my MX2 as a replacement for the standard esc that came with it. I've had 28 flights with it now running on 4s 3000mah 40c battery. maximum amp draw recorded was 62amps. The esc hardly gets warm and the bec has worked fine. No gitters( metal geared servos). The only thing I've had to do was re-soldier the throttle connection to the rx, notice wire loose after about 15 flights. Thanks for a great product HK.

Okay. Lot of test is made with this one. Time for a new REVIEW.
Ubec is outputting voltage with 1kHz switching rate. This is not for sensitive electronics like autopilots and so on... THIS ONE IS FOR HEAVY DUTY FULL SIZE METAL GEAR SERVOS!!! For BIIIIG planes. A lot of energy inside this one. ESC it self has good potential and, as promiced, 70Amp load is really ok for this one. Programming is easy. Not disturbing FPV gear. So anyway it is goog combo for any king of plane with big servos. Also coud be used on any FPV plane, but have to change the ubec. As i did. Cheap electronics, like frsky, some cheap flight controllers are not feeling it self good with this ubec. Nothing critical too, but crappy capacitors on the recievers and flight controllers would make sounds and might be damaged. Chance is 1 to 1 000 000. So nothing to be afraid of. You can add capacitor, something like 5000-7000uF 6-10V to the ubec or any other place. That would help a bit thouse crappy capacitors on the boards. Or go for any other UBEC 2-3A.

Im using this one on my X8 with AIOP FC and NTM Prop Drive 35-48 Series 900KV / 815W - really good combination. Lot of power.

So new price for Overal Raiting is 5 stars - Good ECS itself and powerful UBEC for ACRO and 3D planes or any other "copy" planes that is using standard size heavy duty servos.
Quality - 5 stars, nothing to add here.

UBEC is a real trash! Maybe it is only mine, it is dangerous to connect mine to any electronics. But if you cut it away and use any other UBEC, then you are good to go! Mine is so noisy, that Crius AIOP sensors goes mad, but it is not all- mine Frsky 8ch v8 reciever makes noise!!! HRRRIIIIUUU-HRRRIIIIUUU-HRRRIIIIUUU-HRRRi..... (burning, siren noise, i can not explain) and so on. There are no beeper or anything else inside reciever, it is one of the components make that noise(voltage regulator maybe), and it is dangerous! I made several tests on UBEC (voltage is ok without and with load) and i can not find out what is wrong with it. The most real thing is that its frequency is badly out of normal. The more voltage i take from UBEK, noise is louder. And once again, frsky 8chan v8 reciever is making that noise!!! If any other would say me that, i would not believe it!!! Ubec is going to the thash can.
