Hi

I'm planning to moving my system to a 6.0-6.1V setup. The align stepdown is 0.7 so the tail servo will still see 5.3-5.4v which I believe is too much in the long run. An ideal stepdown would be in the 1V range for me (1.2V may be too much). Any ideas?

Thx

Tony

The .7v stepdown is fine.
It's actually just a large diode, I made my own.
1 volt dropping regulators are not too common, as they like to see more than a volt for the drop out voltage.

use the new fromeco arizona v2 regulator adjustable from 8volts to 5.4volts and constant tail output at 5.1volts for the tail servo

Arizona V2? Thats the first time I've heard about that one... I do have arizona regs in my birds but I was trying to get rid of all the clutter and make a hybrid system using a VR6010 as base and modify it for my needs. I then would need a suitable stepdown to keep the tail servo happy.

HI all
tchavei
I have seen your posts in regard to the 6100 as I have 3 of them
was wondering if it was a voltage problem cause I too have Arizona regs on my machines with 5.1v in the display on the gyro.
Any help would be helpful thanks.
Bob

Hi

Well, I promised not to debate this any further but anyway... I crashed hard sunday. Lost the tail and this time no recovery possible. I don't know if it was the gyro/servo or somekind of power failure (I had still control of other functions like TH and collective). I'm tired of this so I'm replacing everything that could possibly be the cause... Spartan and 9254 will be here soon and I'm looking for a simple regulator to use until the VR6010 becomes available. The VR6010 has a fixed output of 6.0-6.1V so thats why I'm looking for a stepdown.

Tony

seattle_helo: WOW. I didn't knew emcotec had those things. And its a limiter! Thats GREAT! It always regulates down to 5.2V so input voltage doesn't matter

the warnings are for 4.8 nicds (6v charged) 6v nicads (7+v charged) if you use a 6v reg or less you will be fine

I had a 9254 lock down at 6v regulated on throttle. It would overheat and then lock. I'm not taking my chance with this on the tail.

tony use the

spectrum vr5203 on the tail gyro/servo and gov/throttle servo

then use the other regulator on the ele/ail/pit servos

Yeah, it's a nice problem solver. Best of all is the quality. It is a high end device.
