night flight, dim glow wire

[moyesboy]

On my night fly setup I have a couple of 1.5m glow strings on a HK special driver.
I used this on my 450 running an 3 cell lipo and it seemed fine.
On my 600n its running off a 2 cell pack, and although I haven’t actually compared it seemed very very dim when I was flying it. Particuarly the blue string on the tail may as well have not been there (though it was not quite completely dark, the blades were easly seen though). We had to wait until it was quite dark before we could tell if these strigs wer on or not!
So I’m wondering if a 9v dry cell might make them brighter, but it may not be significantly more volts than the 2 cell pack.
I don’t want to strap a trex450 pack to my heli just to power the lights.
Any suggestions?
Are the align ones plenty bright off 2 cells?

I might ask FL to fetch me some align stuff to Notts. I'm hoping to be there until late on saturday, all weather dependant.

A mate of mine runs his 450 setup on a alkaline PP3.
Nice and bright

A mate of mine runs his off a 9v dry cell i believe & its really bright. Runs some glow sticks on it just in case

What about just a small 3s lipo? You can get tiny ones that would do that job fine

I run mine off a 3 cell lipo (11.1V) and I have no probs. Much brighter than when I ran it off a PP3 (9V)
on the 450, I just connect it into the balance lead of the flight pack
You could do the same on a any size pack, just make sure the voltage off the lipo lead isnt over 12V

Spec on my driver says good for up to 14v...thats a chinese spac though.

Will try the 9v dry cell, can put a 1.5v extra in series if need be.
A smal 3 cell lipo would be ideal, but finding one for tomorrow night is the problem.

best bet is to run on a 3s lipo instructions i got with mine said to use 3s also said they would work on 2s just not be very bright

Well outof what I've got lying about I've made an adaptor that connects to the balance plug of my 2 cell rx pack and has 2 nucads in series in it that bumps the volts up by 3v so it is not quite a good as a 3 cell pack but nearly there.
I also made a thing that powers my rx of 2 cells of a 3 cell trexpack, and runs the light string of all 3 - but I don't rewally want to put my 450 pack out of balance so the first solution is preferred.
Loads of glow sticks packed also.
