Can I use these one in my jet? http://www.smart-fly.com/Products/Expander/expander.htm

RE: Power expander?

why not, if you have the room for it , use it

RE: Power expander?

I mean difference between duralite powerbox. More jet jocks use the duralite in jets. The one I show is used more in large aerobatics planes.

Thanks

I4c products has an isolator that works good.

RE: Power expander?

Looking at the website, I seems the expander do not have any functionality to eliminate RF noise due to long leads.

Anybody know which one will do:
-provides full power to servos and clean power to receivers
-optically isolated
-Allow use of two batteries. Do not require separate battery for receiver.
[link=http://smservices.net/acatalog/Large_Model_Units.html]SM Services[/link] have one that's optically isolated, but requires a separate receiver battery. The also have an optical isolation unit only.

I guess only the powerbox does it all.. (?)

See if the glitch buster will serve your needs. It does all you request except the seperate rx battery. It does provide total isolation even from RF that can be generated by battery leads. See http://www.emsjomar.com/SearchResult.aspx?CategoryID=4

mmm, maybe you are not reading the same website I am -

The Smart-Fly Power Expander provides full power to servos and clean power to receivers at an affordable price..

In addition, the input power is regulated and filtered before it is delivered to the receiver. All signals in and out of the unit are RF filtered resulting in extremely clean operation.

Quote:

The channels with four servos have each servo individually buffered for clean signals with long servo leads.

You can use two batterries with the SmartFly Batshare and feel safe. I use it in my 30% Edge with long leads to the tail servos with no problems. This has been a solid setup for me, and can't see why it wouldn't be just as good in a jet application. It does not have optical isolation, so susceptability to other noise generators is unknown.

Spar, Thanks. I guess I missed the reference to RF noise.

I have seen it first hand, it is very light and it appears to be very good, but I haven't tryed it...

I have a power box in my F-18, no problems at all... I used to have voltage problems before, which actually caused a flameout, but know it is perfect and safe...

Saludos...

RE: Power expander?

I am currently using 4 of them in turbine jets with great sucess! They are quite a bit cheaper than the powerbox, also lighter. I also have used the powerbox 40/24 in my 40-50% aerobatic planes but have switched everything to the Power Expander. I am Very Happy with their performance! Anybody want some used Powerboxes I've got four of them in the shop not being used.

RE: Power expander?

Love my Powerboxes but they may all be a thing of the past if this little beauty proves its worth!...

http://www.weatronic.com/cms/index.php

2 receivers, powerbox, matchboxes, Gyro, GPS, Telemetary recording etc etc all in one

RE: Power expander?

for me the best are the DPSI from RC-Electronics...(by keeping a original receiver...otherwise the weatronics stuff rocks...)

but sometime place is not enough...so in my F-15 i installed this:

http://www.rc-electronic.com/html/en.../dpsi_bic.html

a great piece of engineering..
he work with NIxx or Lixx battery..
and you get everything: min/max voltage of both battery, peak current, average and direct...regulated output voltage for servo and receivers...and if one battery fail or is not charged he start too beep very loudly...

How many channels are supported by this unit? I can't tell from the way they break it down on their website. Looks to me like not 10

RE: Power expander?

And can anyone tell me what you don't get by not using the duralite product? I'm building a lightening and don't want to use a 500 device when a 100 dollar device will work just as good.

Any reason not to just use two receivers and two battery systems on the lightening? Certainly dividing the load between two systems should work??
