You guys are hilarious!
Seriously, what is wrong with you people? LoL!!!

You all remind me of my little girls squabbling over anything!!!

Joking aside:

Here is my reason for high voltage.

1)Never had an high voltage setup.

2)Not a performance oriented minded, if I decide to try it on a high performance machine....I have the set up.

3)Some standard servos like Futaba 3152 costs more than the Hitec HV servos.

4)Simple setup to avoid or eliminate potential failures in the circuit.

5)Reading everyone's comments, I am gonna remove the damn switch and put in EC3 connectors with 2s lipo with multiple 3amp three wire connectors for redundancy's sake!

6)At this moment in time, I have 11 different helicopters with various setups and electronics! (Yeah overboard! Gosh, so much fun!)

7)Tomorrow, I could die....the hospital experienced changed me for the better. I am gonna have fun! The next 5 minutes of your life is not guaranteed!

8)Remember, I used to take care of elderly folks. Some of these folks had millions of dollars in the bank. Their pathetic family members couldn't wait for their parents to die to grab the millions!

9)The biggest reason, I don't want to pull servos from the other machines!

Have fun guys, try to enjoy life to the fullest....that is until you get the dirt nap personally!

I am trying to avoid it, still on topic. I just killed the squabble so everyone can refocus on helicopter's power distribution system!

.So I should just wire up an EC3 connector with multiple output to RX?
That's the safest solution but I use the exact same switch on my 90 with 3x 9252's, 2x 9254's and a JR G490T gyro and flying 3D. The only difference is im running a 4.8v nimh pack. As your servos are similar in specs to my 9252's BUT at 7.4v, they will actually draw less current than mine.

If you have a battery cell checker you can connect it to the charge lead on the switch and wiggle all sticks like mad to see what the actual voltage drop is. If it's Spektrum I don't think you run into brown out issues till below 3.5v.
60% of the time, it works every time!

ICUR1-2 You engineer types are too funny.

lol guys like me take what engineers design and make em better or at the least learn what those limits are and exceed them with great success
And you mechanics/techs are funny. Do you go to you heart surgeon, do you say "pass the scalpel Doc, I'll show you how its done" ?

Yes some engineers make questionable design decisions because they are not the ones actually putting it together. But on the other hand Ive seen more than enough mechanics and assembly techs try to "improve" something without understanding the consequences. They even make us take courses in engineering school to study classic failures and learn from them (like the Tacoma Narrows Bridge and the Hyatt hotel elevated walkway collapse - Hyatt is a particularly good example of the trouble that arises when non-engineers ask for design changes without understand the full consequences. Go look it up.).

Please just stop with this showboating. The world needs both engineers and techs. The constant pissing war between them gets old.

To the OP, I have a U-Can-Do 3D .60 airplane that has six digital servos that have over half again as much torque and are slightly faster than the servos that you want to use in a Shuttle. The ailerons average 4.5 inches in width and have 60 degrees of travel each way, the elevators and rudder travel more than that. It has a Saito 100 on it so the plane sees a fair amount of vibration. In maneuvers like Blinders, Waterfalls and Walls, those control surfaces are going to the max and being held there. I'm quite sure they pull more current than you will ever see in a Shuttle doing sport flight or reasonable aerobatics. It has been flown for the last three years on a 3600 mah Lipo pack using the exact same switch that you linked to, with never the a glitch. Unless you have the servos set so that the all stall at the extremes of their travel, I doubt you will have any trouble with that switch.Allen Dye
