The Turnigy Heli-UBEC is a great option for models requiring up to 5A continuous current and 5V/6V output. The output voltage is easily selectable by switch. The input side features a JST plug pre-installed, while the output side uses a JR style plug for use with any receiver.
The Heli-UBEC is compact in size and lightweight, making it ideal for mounting conveniently on your helicopter frame without taking up much space.
Features: • Compact in size • 5V/6V selectable output • 5A continuous output current (7.5A burst) • 6~16V input range allowing for use with 2~4S lipoly battery packs
Could you please do a bit of extensive testing and come up with a conclusion(and maybe a fix).
I want to use the same system on my aircraft (powered by 3S) and cannot afford a glitch mid-air :/
Got this brand new HELI UBEC few days ago.
It causes great problems to my frSky D8R-II receiver with four of HK47011DMG servos. Tested in 5V and 6V mode.
Servos tend to go to extreme positions and then realign themselves. At first I thought it was a receiver/transmitter issue, but when tested connecting receiver to a regular 4,8V power supply, and later with 6V (with another UBEC) - it worked fine.
Perhaps it just creates a lot of interference!
Watch out for this one...
i have a similar issue with my 450pro DFC, as soon as i shake the heli or it gets a lil vibration the BEC switches off and right back on, causing the ZYX-S to re-initialize itself... this BEC is a waste of money. i took it apart and isolatet the coil wich could freely touch alot of solderpoints, but even that didnt help. it still cuts off and on with little vibration...
It's not a question about the fit for a helicopter or for a airplane. It's about what kind of servos you have in your model. Analog servos need 5 volts and will burn up with 6 volts and digital servos need 6 volts and this UBEC has a great switch that will change the output from 5 volt to 6 volts, and this is really great. But I wish it could handle 6 cell 22.2 volts the size battery found in a 450 or larger helicopter.
Hi Guys,I can clearly read the HELI-UBEC part,but can this UBEC be used for Airplanes?
And if not,which would be a good option to run 6 servos lights?
my first option (PRODUCT ID: SBEC-26V) has HORRIBLE reviews,so I need a better option now....
Im looking for a price range of $5 to $8,not TOO expensive :)
High speed & torque digital heli servos need more power (and more volts helps, too.) Plus as someone else noted, it's in a convenient shape and size for heli mounting. Go use it on your plane and feel special too.
Its not radioactive kind of interference,lol.
Its the switching frequency that causes it. Ferrite ring should isolate it. Usually only affects the older radios more.
i tried this UBEC in my HK450pro DFC. As soon as the heli gets little vibration (even a little wind is enough) this BEC shuts off for a fraction of a second and back on causing my ZYX-S to re-initialize itself. it happend first time during spool up, heli just tipped over. then i went through alot of testing, to find out the UBEC is faulty. i took it apart, it is poorly built. the coil inside isnt isolatet and can touch alot of solderjoints. but even after isolating the coil it still cuts off when shaked. a pure waste of money.
