Default what hitec servo should i use?

i'm going to get back into electric 1/10 4wd buggy this winter after being out of the game for a long time. i run a hitec 965 in my1/8 buggy but have no idea what to use for a 1/10. i know i want to stick with hitec so if there's any hitec fans out there let me know. but if there's something betteri'm not opposed to trying something different either. thanks

check out hobbico's digital servos. less $ and great performance. u might find some 'similarities' to the hitec units w/o the price hike.

Do you want a digital or analog Hitec servo ?

5625 works for pretty much all electric 1/10th scale classes. I have that model in my 2wd buggy, 2wd Truck, and my touring car.

Run the other direction!

My personal experience with Hitec has been POOR. The servos just don't seem to hold up very well. I'm running KO and Futaba servos now.

I beg to differ. Hitec servos work very well for me as well as a number of people i have heard from. Maybe you got a defective one.

I have always used a 645MG. Some people tell me it is too slow, but it works fine for me. The last one lasted 3 years and it was only $35.
I have been using a Novak XBR 8.5 Brushless system in my B4 without any problems. I don't do well with too much power-the 8.5 is just right for me. I usually race at Leisure Hours with it and keep up with the faster motors. The XBR has a LiPo cutoff so I don't kill my battery. You can also adjust the drag brake and run a brushed motor if you like. It is a cheaper but reliable set up.

Default 5625 vs. 5965

so i decided on these two 5625 or 5965. which one should i get? and is there any complete motor and esc packages i can buy. it would make things alot easier for me. after all its been awhile since i ran a 1/10 buggy and i seen brushless/lipo setups and they are insane so i dont need a killer setup right now. just want to get my feet wet but still have the power there when i need it.

I have A LOT of experience with Hitec servos. They make some of the biggest bang for your buck servos. I use them a lot for my robotic applications. My favorite is the HSR-5990TG which has gobs of torque (the most powerful one out there in its class) and is far cheaper then any other brand such as KO, Futaba (they are probably the most expensive for what you get), and Kondo...

Back to the subject. The 645MGs are very reliable servos. If you're not going for response time (or transit time per 60-degree travel as it's commonly rated for servos), then the 645MGs does well.

A little background on the Hobbicos and Tower Hobbies servos. Majority of the Hobbico servos are rebadge of the Hitec servos. Just look at their CS-70 servo, it is a rebadged Hitec 645MG.

Their CS-170 digital servo is a rebadged version of Hitec's 5955TG servos (not to be confused with the 5990TG servos).

The only difference is that CS-170 cannot be programmed by Hitec's digital servo programmer (not that you would need it for rc car application).

Tower Hobbies servos are often a rebadge of Hobbico's at a higher price. I use their TS-70 servo, which is a rebadged Hobbico CS-70, which is a rebadged Hitec 645MG servo... Once in a blue moon, the Tower Hobbies servos will be lower in price then Hobbicos. Usually, Hobbicos are much more cheaper then Hitecs. If the prices are the same between Hobbicos and Hitec, I'd go for Hitecs but there's no other reason to if the Hobbicos are generally cheaper.

Hobbico only lacks some of Hitec's latest greatest line, which are the robotics servos (same size as the standard servos we use in our 1/10th car), which are the HSR-5980SG (steel gear) and the HSR-5990TG...

Some of Hitec's earlier high-torque servos had thermal issues where the FETs inside would just blow out under extreme use (such as in Robotics), but if used for steering (say in an RC Car), it's quite a benign way to use it so I wouldn't worry. Hitec's 5995TG (not to be confused with the 5955TG) would blow when going thermal, but their new 5990TG servo attempts to fix this by having a thermal shutdown inside. The 5980SG also has this feature, the difference between it and 5990TG is that it's steel gears instead of titanium, and the servo casing does not have an aluminum extrusion for heat sinking.

I highly recommend the 645MG if you don't care for a sub 0.2-second transit time... I use a rebadged, rebadged (Tower Hobbies TS-70) in my B44, and I also use 18 (yes, eighteen!) real Hitec 645MGs in my Hexapod Robot.

I hear many guys use AE servos in their ride. I've been meaning to check it out. Using servos in robotics (torque is the main feature you look for in robotics) versus RC Car (somewhat torque but more transit speed) is quite a different experience... Just remember to get minimum torque you need to move your front pairs in dirt (which takes quite a bit of torque, upwards of 133oz-in or more...)

The 5965 is your best bet as it has more torque and faster the the 5625 but is $35 more .IMO the little difference isn`t worth $35 for a 1/10 buggy . I`d go with the 5625 .

As for a brushless setup , I`ve had a Novak GTB/6.5 in my XXX-4 and XXX-CR and is great . Right now I am in a toss between Novak and Castle Creations . But if your track requires sensored systems C.C. is out of the question as the are sensorless , until the Mamba Max Pro comes out .
