Receiver packs
 

OK guys i had a few questions for you.

1.)Instead of using a external ubec with my quark can i use a extra battery pack like a receiver pack.
2.) i will be running anywhere from 14.4v to 19.2v would it be safe to run a receiver pack with my 333oz servo on this voltage with an added receiver pack
3.) when using a receiver pack does it act like a ubec (external) and just give voltage to the servo.
4.) how would i use this. What do i need to do to make it work. I know with the quark and a ubec you just cut the red wire to disable the bec, but what do you do with a receiver pack.
5.) does anybody here use a receiver pack. Got any info.

The reason i want to use a receiver pack is because i already have one and i just want to keep the electronics as simple as possible. Ii know a ubec is not that completed it is just one more thing that can go wrong (not saying it will it is just, i am not that familiar with this piece of equipment) and one more thing that i have to solder. Would using a receiver pack fix this issue and allow me to have power for the servo safely and be reliable.(weight does not bother me) Thanks guys.

1 yes, no problem
2 yes, the receiver pack has nothing to do with the rest of the circuit; you can use any voltage on the setup you want
3 Yes, you just hook it up to the receiver. (some speedo's need to have the red wire removed)
4 You simple hook it up to a loose channel on the receiver.
5 Yeah. i used it on a savage, i used KAN1050 cells, but i also had a GP1100 pack.

how well does this work in comparison to a ex ubec. On simple terms (which i like) is the only basic difference that the reviver pack just powers the servo and the ESC the motor, and the ubec never needs to be recharged but it pulls a safe current from the batts to run the servo. Right. Also with the quark do i need to remove the red wire. and is there any other programing i have to do i this Field when disabling the bec. thanks

Well, a battery pack probably has a higher pulse current rating than most UBECs.

The advantage to a UBEC is size, weight, and less stuff to charge.

Unless the ESC you are going to use doesn't have a BEC or has a way to disable the BEC (like the black jumper on a BK Warrior), you need to remove the red wire. This includes the Quark and MM. No other programming is necessary.

does the battery control just the stering or does it add over all voltage to the setup that goes to the motor.

A receiver pack just supplies power to the receiver, which also powers the servos. It does not power the motor.

If you're going to be powering a 333oz/in servo with a receiver pack, I hope that you have lots of them. It's going to be kind of funny when you realize that you're going to have to stop running every 15 minutes to charge your receiver pack. Well, 15 minutes might be a bit of an exaggeration, but I'm sure that you get my meaning. Those super high torque servos suck some current and what really sucks is when the radio switches off due to insufficient voltage and you had just pulled full throttle a split second before.

I've actually had a different experience with the 5955 (333oz./in.) in my Revo with a receiver pack. Sometimes the pack will be run for over an hour, over a period of a couple weeks, before I recharge it. It seems to work fine during that entire period.

MetalMan, that is unusual, from what I've seen. Oh, I'm also assuming that the servo that we are talking about is digital. Is it? Is the 5955 digital?

I know that with a JR Z9000T, I had to change receiver packs every third tank or so when I was running nitro. For long runs, I used to switch to an Airtronics 358, just so that the battery would last longer.

The 5955 is digital:

When you were running nitro, you also had a throttle servo:).

How have I missed out on that little gem? Everyone around here runs either Aritronics or JR, so I've never messed with any of the Hitecs. Have you found it to be dependable? Do you feel that the torque rating is accurate? Was the programmer necessary?

BTW, I was running the Z9000S throttle servo too. I forgot about that.

I too is running the 5955 hitec digital servo running on a 1600 mah receiver pack, No problems and dependable for over an hour of racing.I'm using it on my G2r revo

If the 5955 doesn't put out as much torque as it is rated at, it still feels very strong. And, it's still a pretty fast servo.

Last week I got an Airtronics 359 (94359Z). Excellent servo - 200oz./in. and 0.10sec. transit time. My LHS discount brought it down to $90, and the LHS I work at happens to be part of the chain where Airtronics is now located (in the warehouse right behind our store), so getting Airtronics equipment serviced will be free for me :).

That sounds like a perfect steering servo for a buggy...

I thought that the 358 was the hi torque and the 359 was the hi speed.
