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.
correction: today most analog servo's specifications are for 6 Volt , old servo's from years ago yes only 5V allowed
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.
