Hitec 5995

[forgues research]

I hear a lot about the hitec's 5955 as a very powerfull servo, but I rarely hear of the more powerfull and same price 5995's is there a reason why people are mostly going to the 5955 instead of the 5995???


Thanks for any info

They are not more powerful.

The 5955 is rated at 4.8 Volts and at 6 volts

The 5995 is rated at 6 volts and 7.4 volts and it has a bigger sweep with its arm

They are advertising the same servo for two different tasks, airplanes and robots.

No actually at the same voltage and the 5995's are also faster.

STill doesn't tell me why people are buying the 5955's instead of the 5995 mostly when you don't need a regulator with the 5995.

I was going to suggest looking at the Hitec web site but the 5995 servo is not listed - oh well...

check Servocity.com its there

Roger

but why are people not buying the 5995, that is the original question

Huh, you could be right, servo city also has these specs though.


5995:

Operating Voltage Range: 4.8-7.4 Volts
Operating Speed (6.0V): 0.15 sec/60° at no load
Operating Speed (7.4V): 0.12sec/60° at no load
Stall Torque (6.0V): 333.29 oz-in. (24kg.cm)
Stall Torque (7.4V): 416.61 oz-in. (30kg.cm)
Standing Torque (6.0V): 433.27 oz-in. (31.2kg.cm) 5 degree deflection
Standing Torque (7.4V): 541.59 oz-in. (39kg.cm) 5 degree deflection
Operating Angle: 90 Deg. one side pulse traveling 400usec

5955:

Operating Voltage Range: 4.8-6.0 Volts
Operating Speed (4.8V): 0.19 sec/60° at no load
Operating Speed (6.0V): 0.15 sec/60° at no load
Stall Torque (4.8V): 249.96 oz-in. (18 kg.cm)
Stall Torque (6.0V): 333.29 oz-in. (24 kg.cm)
Standing Torque (4.8V): 324.95 oz-in. (23.4 kg.cm) 5° deflection
Standing Torque (6.0V): 433.27 oz-in. (31.2 kg.cm) 5° deflection
Operating Angle: 60° one side pulse traveling 400usec

Here there speeds and Torque seems to match exactly at 6V but you see the 5955 is rated at 4.8V and then at 6V and then the 5995 is rated at 6V and then at 7.4V.

I dont really know anything about them, I have heard like 20 different times that they are the same servo when it comes to motor and gears so no matter what voltage they have they output the same speed and Tork, but there are some other subtle differences like the operating angle and maybe other things.

Roger,
Trust me, this has been discussed to endlessness on the internet. I ran 5995TGs without regulators (2-cell Li-Ions) - they do not like that, I burned up 1 or 2 that way. Others just started acting strange, I put a regulator in and they worked fine. There are some quirks about the 5995TGs that make them not desireable for RC:
1. The signal width they will see is less 200mV at one side.
2. I could never use ATV over 98%
3. If you program them, they will act different from one side to the other

I run my 5955TGs at 6.5V, they are happy, strong and fast.

The 5995 is not faster than the 5955, in you post above you are listing the 5955 at 4.8 and 6.0V, the 5995 is listed at 6.0V and 7.2V.

Trust me, 5995TGs will only give you a headache.

good points!

OK I do have the 5995's already and never had any problems and run them on 6 volts anyway.
I just wanted to know why they are not mentioned as opposed to the 5955.

Thank you for the thread , most interesting. At least now I know but for my use, I have no problem with the 5995,
