Quote from: Marcol on January 09, 2020, 18:45:19 pmIt begs the question, why do you think you need a separate battery for the Rx supply ? The ESC is more than capable of supplying the Rx and servos. All you're doing is adding more weight unnecessarily. I use the onboard bec on all my electric models up to 4s without any problems and even some more sedate 6s models.
Quote from: PDR on January 11, 2020, 19:12:14 pmI'm kinda hoping that you're using a fourth servo on the elevator as well, or flights could be a tad brief...If you're only using four standard-size analogue servos on 4s the ESC should be more than able to handle the current. If you were in 6s and the BEC was a linear (UBEC) r5ather than switching (SBEC) then there might be some concerns, but I personally would stick to the BEC supply as more reliable. That way you never have to worry about whether the receiver battery is charged, whether you left the model switched on etc. Each flight battery change guarantees the radio has plenty of electrons in the tank!What ESC is it?PDR
Quote from: PDR on January 11, 2020, 23:44:31 pmThat has a switching BEC which should handle 4 normal servos without even trying. You shouldn't need the complication of a separate Rx battery with that setup.Don't be fooled by claims that any ESCs were specially designed for particular brands. Pretty well all the ESCs we see are designed and built in one of five chinese factories (Hobbywing, SkyRC Technology Co, XingQiong Technology, Sunrise Model and HiFei) and given different labels for the different brands. EFlite, Dualsky, Purplepower and Turnigy ESCs are mostly made by Hobbywing. Sunrise make most of the Jeti/Hacker ESCs plus a few of the larger Purplepower ones. IIRC the Overlander ones are actually XingQiong Technology products.This is not to say they aren't good products - they are. It's just that there are lost of the same products out there at massively different prices. Jeti Spin controllers sold for a hundred quid are identical (made from the same components on the same production line in the same factory) as some turnigy ones which are under thirty quid...PDR
