ds610 servos possessed

Yes. I run one one on my 550. Do some research there may be something better/cheaper. If I find one I'll let ya know. This is the one I'm using: http://www.readyheli.com/Western_Rob...wrl-hbechc.htm

A search on the 600ESP forum brings up a lot of guys are using the HC Hercules.

at 6v... the Aligns are .03 sec faster (.08 compared to .11sec)...and make less torque (Align makes 12.0kg/cm and Hyperion DS20xSMD makes 16.0 kg/cm) .. I know I wouldn't be able to tell the .03 difference in speed.... that being said... Bobbybe heard about centering issues... I haven't... the guy I fly with weekly uses them on his 600ESP

Sorry, I misread the torque specs.
A lot of people are running DS610's @ 8v which says a lot about what they can handle and probably bumps up the specs quite a bit.

And there is a noticeable difference between .11 and .08. Basically the difference between a cyclic and a tail servo.
The 620's are 10kg.cm/.07 @ 6v.

wonder how much amps it eats out of your flight time? just a thought.also cc are supposedly about to launch some insane switchmode bec...may be worth investigating

if the servos can handle 8v... running a 2s LiPo with a step down for the tail would solve all his power problems

Will an Rx and Gyro be Ok with 7.4 V ??

Yeah you guys should fly mini servos on CHP frames and not eat up so much flight time

or fly Spektrum DS821's or Hyperion or INOLab servos and not eat of the amps... or use a flight pack... or better yet... Use Ben's frame WHEN HE GETS IT DONE!!!!!!!!!!!!!!! then use full size servos and still have direct to swash

lol All in good fun.

so while all you wiseasses were making jabs at my lovely new servos and the far inferior craperion servos i found this on the cc website:

CC BEC Usage Advisory #1: Multiple Servo Setup
PROBLEM:
High power digital servos in larger helis overload CC BECs and the heli can be lost.
SOLUTION:
Use a larger output BEC or use multiple CC BECs wired as shown in the Multiple CC BEC Setup Diagram. Yes, this is VERY awkward. We are working on a better solution for high current applications.

EXPLANATION:
CC BEC is rated to deliver a MAXIMUM CONTINUOUS output of 5 amps when the input voltage is in excess of 12V DC. Our tests show that ONE JR 8717 servo draws 2.2 amps under load. A system using just 3 of these servos (not counting tail servo, receiver or gyro) would draw more than 6.5 amps during flight. When one adds in the draw of the tail servo, receiver and gyro, the load is much more than the 5 amp continuous load the CC BEC is designed to handle with greater than 12V input. CC BECs will eventually shut down due to an overheating caused by the overload.

so apparently it's an underrated bec for the application.

so here are my options: shell out 90 and get the hercules super-mini (friggin sweet bec) or spend another $20 on a new ccbec and use two of them. i've heard another guy that got good results this way so this may be the cheaper route (especially since i'm saving up for my new hh frame)

[kahn10]

or...shell out about 20 bucks and run them straight off a 2s lipo with a cutdown for the tail.a 6.5 amp draw is 10% of your motor working hard bro.why draw that from your flight pack?

[kahn10]

scratch that 20...make it 10

[Jerrymac]

Huh, wise asses, geeezzz and we was tryin to help. And that's the thanks we get.

Glad you got it figured out.

[kahn10]

yeah...and when was the last time ya read my rx pack went up ...destroying my incredibly precious misaligned ****ing servo's

[Jerrymac]

Hey Bobby, I got an extra lawn tractor battery in the garage in case you need an Rx battery to power those servos.

[kahn10]

stability plus....

[s0laris]

hmmm

I have an outrage 550 with a scorpion commander 90 amp esc with 4amp bec.

I am running 3 ds620's for cyclic and a s9256 on tail with spektrum regulator for gyro/tail

you had me concerned so I plugged in a pack and set throttle hold on.

I thrashed aroudn BOTH sticks for a good minute and the esc was not even warm. Like it was not even turned on!

My thoughts are you might have too much cyclic throw. on these bigger birds you only need maybe 40% elevator/aileron.

[bobbybe]

my esc was fine it was the ccbec that was getting hot as hell.(btw- what bec are you using?) i've been trolling and have found at least 2 other people that had the ccbec/ds610 combo and had the exact same brownout problem. i don't think it's the throw because i'm only at 42% and when the servos would freak out like that you were seeing them go beyond their throw limit set by my dx7. apparently they'll suck more then 5a which is why i need to either run an rx pack (which i'm thinking may be the cheapest option) or shell out 60-80 bucks on a hercules 5a hvbec or a hercules 10a super-mini bec.

ok so alice, mystic, jerrymac, make yourselves useful () and tell me what route to go for a voltage regulator that can handle high power servos

[s0laris]

well nothing on the esc/bec unit was mildly warm.. so I dont know what to say.
