BeastX / Align 610s ~ 8V set-up?

[Lad]

My latest acquisition (Trex 700n) is currently in the workshop midway through the build and it's almost certainly going the FBL route..!

I know many have commented on the increased power consumption when running the BeastX at 8V and others have commented on potential heat issues when running the cyclic control loops at 200Hz.

Notwithstanding these ‘quirks’ are any managing to run the unit at 8V (2S) and doing so reliably?

I guess my concern at this stage is not so much the BeastX more so the servos (Align 610s)

Thanks,

Lee.

Good Question,

I would usually run the DS610s @ 8v with a Flybar,

But since the extra work load that is put on the servos with going FBL and the added factor of the servo's not rated for 8v, I would run them at 6v, I did a handful of flights with them at 8v on Vbar, But knocked it down to 6v again as it was a tad too risky for my liking.

They're not officially rated at 8v (only 6v) so I personally would be very reluctant to do so, but I know Tim (busterboy) and callum have done so without any issues.

i run my velo 50 velo 90 and 700n all at 8v via spekreum ar7100r all flybarless 50 on beastx and 90 and 700 on v-bar and have done for ages and had zero probs (touch wood) no probs and both in summer and winter conditions

Dont do it mate, its not worth loseing a heli or hurting somone, when mine failed it was pure luck I got it down in one piece.
you can run Hv 8volt through the cyclic but only with an external bus Not through the Beastx.
Or just run it all at 6volt.

ps mine lasted 2 months and prob 100 flight before it went wrong

According to the distributor, the Beastx shouldnt be run straight off an un-regulated 2s pack.

I would stick a reg on it, or look at using LiFE packs.

The manufacture does state ‘LiPo 2S Possible’

http://beastx.com/products_specs.html.

I’m happy the BeastX unit can happily handle the 2S voltage and even pass sufficient current to the servos in a pass-through configuration.

What concerns me is the cyclic control loop frequency of 200Hz when combined with the extra 2.4Volts (that’s 2.4V over the specification for the servo but perhaps more relevant is it’s driven at 4 times the standard refresh rate). It would be interesting to understand how the ‘feel’ differs when the cyclic loop is run at 50Hz rather than 200Hz ~ Anybody tested this?

It is also capable of 50 amps according to Walter, but that is what the distributor has said regarding the issue.

I use a LiFe pack (6.6V) and it seems to work well with the BeastX. I use both Hyperion 3000mah (fits well up front in the 700e, 610s with HV tail servo) and the older 2300mah A123 packs (in 700n with 7100R supplying 5.2V to the tail servo).

Lee, when I had my FBL 700 with 610's, that was on 8v Didn't have any problem in the time I had it!
