**some dumb questions about servos and receivers -** 01.31.2007, 04:32 AM

I am currently building an brushless revo. I have installed one traxxas 2055 high torque servo for steering but it struggles to turn the wheels at a standstill. Is one servo enough?

By the way, I am using the radio and receiver from my old super hornet. Could this possibly be under-rated for a high torque servo. Its hard to find the current ratings of this type of thing.

If I have to replace my radio gear, can anyone recommend a good 2 channel radio and receiver.

Thanks

Well, the RX won't limit the servo power. It's a question of what your BEC or RX-batt can put out.

And yes, one servo can be enough. But certainly not one of the stock ones :)
Check Mikes store for well-priced substitutes. (anything above 150oz should do)

I hear alot of guys in the states use JR radios. Again, check if Mike has something in the store.

Thank you

A single 2055 is not enough for a revo, you need at least a 140 to do the job. I'd recomend a hitec 645 at the very least

I heard the 645's can cause glitching. I would go to this one http://www.rc-monster.com/proddetail.php?prod=HS-5625MG if you are going to spend money on a servo. Or even a better one. I've always found that I kept upgrading the servo...so may as well get a good one right off the bat.

Newe, where did you hear about that glitching with the 645's? Im using a DX3 with that servo and have yet to test it, but am hoping this servo wont be a problem?!

Can't remember, I think car action forums. I use the JR radio XS3, and the 645 lasted a whole two to three runs before it was glitching and then fried. Got another, did the same thing. I run the Airtronics that Mike sells, and it's flawless!

ERR, i hope it works with the DX3..

How much did you pay for it?

Sylvester · 01.31.2007, 06:38 PM

The servo or radio? I payed 54.99 CAD for the servo..

Servo. For more torque, you could have gotten the one listed above http://www.rc-monster.com/proddetail.php?prod=HS-5625MG . And it's better. Sell the one you have, and get the one in Mike's store.

Otherwise, use the 645...some have luck, but some have issues. I've had issues with two of them, right in a row, from different distributors. But what you paid for that one, you can get a better one that will work for sure... .02 is all man...

Also, IMO, may as well get the better ones anyway. they last longer, perform better at higher speeds.

Uhh, i think there is a mistake here. I use the HS-645MG. It has 133 oz of torque @ 6V. The one in mikes store (HS-5625MG is only 94.43oz.)

that is possible. lok at the pic too, it says 645...lol! Get the other one with the heatsink....that I hear is really good too...sell the one you have and put it towards a good servo.
I use the Airtronics in the store...thing is fast and torquey
Or, use the 645....you may have good luck with it, others have....

Ha, i didnt notice that. Mine is a newer version, i think, since my sticker on the servo is a different hitec logo. If you want i can get a pic.

A pic would be cool. I would try the servo first. If it does not work well, then sell it on ebay or something. But, I think you'll find that you'll still want more torque anywho...
