9254 servos
are no good at 6V. plus there tork value would be to low for cyclics and way to low for use on FBL

hi
i think the 2in1 is enough for this set up and you can see it in the future 700le 3G combo with the ds610 :https://rc.runryder.com/t569213p1/

That is my thought also. That is why I run the arizona reg.

The arizona regulator website says 8.4v input 17 watts continuous or 28watts with some airflow. Thats only about 3amps. The align b6t 2in1 is 6amps continuous. Someone correct me if I am wrong.

There are a couple of threads dedicated to this issue.
Apparently all three servos at the same time could require a lot more than 6 amps at an instance since FBL works the servos a lot harder and the 2 in 1 has only a tiny wire to supply 6 amps.

People are afraid that this is not enough and could cause failures and maybe fire on the long run.

So to be safe either use another regulator, or straight power from a lipo.

The best solution so far is the 7100r(assuming jr) using LiFepo4 batteries straight.
They give 6.6 volts not 7.4 so you don't risk overpowering your servos really.

That's what I will be doing and I have 2 align 2 in 1's on the shelf. I just don't want to risk it until it's proven that it can take it..

My question is alighn has a 700n flybarless kit coming out with the 2in1, does any one think they would sell a system that could cause major issues? So far everything I have bought from alighn, has worked just the way it was supposed to.

I share your skepticism and agree with your logic, but Align has been known to put things in the market fast, and upgrade or attend to problems on the go as things are tested by public.

So an issue like this is something that could cause a serious crash and according to some that have run some tests, the requirements are high, so really, do we want to risk it?
And I say we because I am at the same place right you right now. Waiting for my system and trying to decide which way to go.

I never trusted the 2 in 1 in the past because of things I had heard, but finally installed it and I like it a lot. But with the new power requirements I am skeptical.
What can I say, I just don't want to find out the hard way since I have a better regulator at hand. I just have to resort to a switchglo again...

I think the math might be wrong here. Here is a link to the web site.
http://www.fromeco.org/Products/02F...00/Default.aspx

The max rating in amps is 17.5 acording the the chart. I called Fromco and asked them befor i bought there regulator "How many amps is the regulator rated for?" and i was told 18.

Any way this is about the 2 n 1 sorry for hijacking the thread.

copy and paste from the website;

Electrical Specs
Max Amperage 17.8 Watts no Airflow / 28 Watts 1m/sec Airflow
Max Voltage 10
Operating Voltage 8.4
Quiescent Current Load <=84uA
Voltage Droop Under Load .05

Maybe its just a typo like the word Droop.

4 Gallons so far (28-flights) with the Align 2-1, AR7100R and 3G. No issues what so ever.

um why are you running a 7100R if you are running a 2in1 kinda defeats the purpose of the 7100R doesnt it?

I thought this thread was about 700N 3G FBL...

I use the AR7100R to utilize the rev-limiter.

A friend I fly with is using a similar setup because his servos won't take 8v. It drops the servo output to 6V but lets him use the features of the 7100R such as the rev limiter.
