Heres an ESC for those that like to push their equipment a little - hotliner pilots 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 wont safeguard you against is Lipo cell failure - Always be sure your Lipos are up to the task at hand and that you are drawing less than their rated C current.
