HV Servo Switch setup?
Hi Guys:
I'm wrapping up my Avant build (still). This is my first HV setup. I'm not running any regulator, trying to keep things really light and simple. But I would like to have a good switch setup for the receiver battery. I want to have at least two power leads going into the receiver. I've been hunting for a failsafe switch that is unregulated that has a heavy wire in with deans connectors for the lipo (possibly two lipos) and two servo type connectors to supply power to the receiver. I've been looking around and not found anything exactly like I'm looking for. What are you guys with HV setups running? If I can't find a switch, I'm just going to solder up a deans connector with two servo pigtails, and plug that into the lipo with a deans, but I'd kind of like a switch. Cheers! Lee

I think most are just using 2 rx inputs soldered to a deans connector, or what ever connector someone chooses. I personally switched back to using regulators for this purpose, as the con's of not having a fail safe switch outweighed the simplicity of direct 2s hookup.

Hi Jason:
What regulator are you running and are you running HV servos? In an HV setup, having a regulator seems to somewhat negate the intent. Thanks!

On my eAurora I am running a newly released ProTek RC Regulator, it has a lot of value in a great package. You can differentiate the voltages from the receiver, and the cyclic servos. The Cyclic power bus has select-able voltage control of, 5.2V/6.0V/6.8V/7.4V/8.4V (direct bypass mode), and the receiver voltage is adjustable through the same voltage ranges as well. This is all customize-able through dip switches located on the back of the unit.
Something that is unique to this regulator, is there is an audible tone when the push button switch is both turned on, and off to let you know that the model is on. It also is not a simple push for 1/2 a second to turn on, and 1/2 a second to turn off, it takes roughly 3 seconds both on and off of the button being pressed to turn the regulator on or off. Along with a low battery warning (an audible alarm, also programable). You can take a look at it here: http://www.amainhobbies.com/product_...tage-Regulator As for my nitro, I am also running a regulator, the JR VR6015. This is an extremely simple regulator, pretty much plug and play. 6V output constant, 15A power bus, built in safe switch. Simple, and effective. http://www.amainhobbies.com/product_...-System-15A-6V

That's a nice regulator, but overkill for an HV setup. I guess I'll just make due with some Deans connectors.

I was considering an X2 Reactor for my nitro 50. Mostly for the pin-switch, but I ultimately just used a simple on/off switch in the end. Probably not the safest way to go and I certainly wouldn't trust it on a bigger ship, but I agree that it kind of negates the point of going HV if you have to be on a regulator anyway (at least on a nitro).
I use a WR Super BEC on my eAurora as well as my 6HV. Both work great and it's all the same connections, so less to worry about overall. Since I have to plug in my main packs anyway, I plug in one and wait until I'm ready to fly to connect the other one. Almost like turning it into an oversized 450 (only this thing flies 100X better)

I have a Reactor X on my Vibe 50 and it is a great piece of kit. But I'm using standard servos on that bird, where the regulator makes sense. I've been picking through various web sites, and haven't really found any good RC heavy duty failsafe switches that don't incorporate a regulator. With the push of HV servos and setups, I'm surprised.

Probably because most either just run direct connections or use BEC's. HV servos tend to be less power hungry than coreless servos, so in all reality they don't need quite as heavy duty backing. But then again the BLS servos nowadays are really starting to catch up to corelesss as far as strength and speed goes. It would take some really gnarly BLS to out-eat some 8717's or similar so those are still the high-power vampire benchmarks of the industry (as far as I know anyway).

Scott Gray has a new Reactor regulator switch specifically for HV applications. Really like the switch. I'm working on getting one. I have the older Reactor on my Vibe 50 and it's a quality piece of equipment.

I use a BEC, but if I was running all HV servos and a 2s lipo, I would omit the switch and use a Deans or EC2 Y'd into two servo pigtails. Switches make me nervous. Switches can vibrate closed.

Did you have any problems with the switch? I have a Reactor X on my Vibe and it has worked great. It has a Pin flag switch that you pull out to turn it on. The new Reactor HVX has an electronic switch that fails on. I would think on an electric heli this should be fine.
I have a deans and a Y connector with two leads into the receiver now, but the setup just seems cheesy to me. I don't like the Deans with such little wires, they are pain to connect and disconnect. In fact, I don't even like them on my main batteries, but at least with the larger wires they are easier to deal with.

Have tried EC2 connectors from Horizon yet? They are much easier to use than Deans.
Here is a heli switch I once made: http://rc.runryder.com/helicopter/t607152p1/
