Anyone running BLS451 swash on 8v?

[moyesboy]

I've done a fair bit of flying with my BLS451 running direct off 2S lipo on my 600n.

After fitting the beastX everything is now back on 6v via the align 2 in1.

I want to return to a split power supply with RX and swash servos running on 8v, but everything else including the BeastX running on 6v.

I could put the 8v through Rx and BeastX, and just split the tail servo off - that would be simpler.

Does anyone have experience of running the beastX on 8v? I see they only show 6v for the BLS servos though futaba rate them on 8v now.
Can anyone point me to someone having problems doing it?

While the precision of the heli is transformed, I did notice my swash servos were slower if you wiggled the stick (like for crack) than they were before when they were on 8v.

Perhaps I risk my servos on 8v - but perhaps I risk frying my 2in1 running all the electrics with flybarless? (though current drain is probably half that compared to ds610 servos).

I recall recent (last two months or so) posts about running Bx off 8v aint so good, despite the specs saying its up to it.. it was on Here/HF and the Bx Forum posting quite a few queries .. I'll see if I can find the threads for you. Yes.. the Bx runs weird judderly slow on the bench.. its just the way it is and fine in the air.

IMO.. its fbl anyways.. theres more negative than positive reasons for running 8v.. so why bother?

I'm thinking keeping the amps down through my 2in1 might be the positive. The way I plan it 8v wouldn't go through the beastX, only to the servos - I'll try it that way. As far as the beastX is concerned it only sees more powerful and faster servos (or burned out servos if I'm unlucky).
If you can post links to the posts that would be interesting as I can't find any mention of it on theBeastX forum.

Not quite answering the question, but I had two 2 in 1s go wrong running BeastX with DS610s on the 700 and BLS 451s on the Velo- I'm sure they do not like the current draw and if you look at some previous threads where the maths has been done, Align 2 in1 with FBL can be marginal on the current draw tolerances. I went the ElyQ reg route on both and that is great as it has programmable cyclic voltage output- not tried it yet though :P and still running at 6v.

I did and all was fine.

Cant see the point though tbh. A LiFe is the way to go

[moyesboy]

What happens if run the swash on an A123 pack, and power the 2 in1 with that. Would the 2 in 1 drive the throttle and tail servos at 6v? and light the glow?

Just run straight LiFe power to everything Both Paul and I have been doing this for a while on our 700's with V-Bars, and it couldn't be simpler tbh!

[Rctintin]

Straight LiFe for me as well on the 700, but mine is FBed at the mo. It's the same voltage as running 5 cells nicad, as we did before Lipos.

[moyesboy]

Straight 2S A123..but dig a stepdown out for my bls251?
I'd have to find my glow stick!!?
Then I'd have to keep ducking when the glow stick falls off after takeoff!

I ran 7.2 though my 451 with a elq reg no problems at all .

[Eckchaz]

I have gone the ElyQ and Switchglo pro route.. No glowstick and couldnt be happier

I'll try find those posts for you mate

[jamiem]

BLS251 @ LiFe voltage on my 700 6.6V has been just fine.

I always ran my 451's on straight 2S LiPo with no issues at all. Great servos

[moyesboy]

But tom, was that with a flybarless? I've done a season on my BLS451 on 2S lipo with the flybar - but the flybarless will work them harder.
...but they were cold on 6V after quite a thrashing flight.
