servo

A quick question for you guys:

When I first built my F.T. back in December of last year, I installed the Savox-0252MG servo in it, with a Spektrum "glitch buster" --> This One After installing this setup, I never had any issues with glitching or brown-outs.

Recently, I decided I wanted a faster servo, and picked up an infamous Savox-1258TG. After installing it, along with my Spektrum "glitch buster", I keep getting a "glitching" sound from the servo (even when it is on, but at rest). There is no twitching going on, but just noises. I am assuming this is now occurring b/c this servo draws a larger amount of power then my previous one. So, should I pick up a Castle external BEC --> This One to solve this problem?

Also, if I do need the Castle BEC, what output voltage should I set it at with my CastleLink... 5V? Any knowledge would be appreciated. Thanks





Yep, I agree, it is expensive. That is one of the main reasons, why when someone asks what kind of SC10 they should get, the RS or the Factory Team, I would typically suggest the F.T. Unless someone is very young and just planning to play around with it, the F.T. will cost more up front, but will give you a truck that you can use even at a professional level. I mean, R/C is something that people usually start doing just to see what it's like, and end up loving it, and wanting to move on to better stuff. The F.T. kit not only allows you to build it exactly how you want it (and forces you to learn the in's and out's of your truck), but also has many upgraded parts that will help with the overall performance of the truck.


All those Savox servos are digital and make that sound. Has nothing to do with the current draw from the servo. No worries. If you want to get away from worrying about your servos draw dump that Castle MMP and get a Tekin RS or RS Pro. The BEC is crap in those Castle ESCs. Have used both and the Tekin is a much better ESC all the way around. There isnt a servo out there that will brownout with the Tekin.

You can run the RS wheels on them, and it will not change your width. Also, JConcept makes aluminum hex adapters (wouldn't recommend at all), and AE make plastic hex adapters (the same ones that are on the RS) which are a bit cheaper then the aluminum ones --> http://www.amainhobbies.com/product_...ter-Set-SC10RS. If I were you, I would just go with the Avid ones, only $17 for all four of em', and they sound very promising :nod:

As far as the shocks go, the ones on the F.T. truck are significantly better then the shocks that come stock on the RS version. The F.T. shocks are V2's and are threaded (for easier adjustments), and have bleeder caps on them (for simple shock bleeding). In addition, they are very easy to build. Many owners of the SC10RS will often install the V2 shocks on their trucks because they are a very useful upgrade. Here is the product listing, just incase your interested:

Fronts:

Rears:

Yea the bleeder caps are a must on this truck if you want air free shocks. Since there is no bladder and the seal is on bottom of the tread its a real PITA to get all the air bubbles out with the stock or Al caps.

With a MMP you should always use the BEC. You don't need to set the actual ESC voltage since it wont power anything. Set the BEC voltage to what you need for RX and servo.

Thanks for the help guys! However, it sill seems like I'm getting a few different answers. @Brushless420: Are you saying that the Savox-1258TG is going to make that noise regardless if I use the Castle BEC or not? (Also, I will keep that in mind about the Tekin ESC's when I go to build my next R/C vehicle. I very well might pick up one then, I've heard great stuff about them.)

@J_Bone: Do you have a MMP installed in you SC10, with a Castle BEC, and the Savox-1258TG? Does it make any "glitching" noise at all? I know a few guys at my track have the 1258TG servo installed, and it doesn't make any noises (if I recall correctly).

Does anyone else on here have a MMP, Savox-1258TG, and a Castle BEC installed on their trucks? Does your servo make any "glitching" noises, or is it silent while operating and while at rest?

If it leaks around the outdrive replace the orings and grease them up good when you install them. You can use black grease or I prefer green (teflon) grease. I've gone between both diffs in this and other vehicles and prefer the gear diff because I feel its more durable.

What does rtv stand for? Is green grease the same as ae green slime? Thanks

going to be running a novak 8.5 and gtb in it lookin to gear it to a 18/81 i think.we have 2 different tracks we race a 1/8th scale large jump track that hardpacked w/ loose sand out of grove, other is intended for SC realy bumpy small bumps/jumps track stays moist and it hard loomy dirt

My q was lost jn the show and tell so let me ask again

I no longer have a MMP esc, I went Novak. But the MMP did make my airtronics servo noisy as well. Since switching its not so noisy. It still makes a noise but nothinging like before.

Yes , hexes are better. They are cheap to convert though. I don't see how your other truck matters to hexes up front on a SC10.

RTV is a type of silicone. It is used for lots of different things, mainly on automobiles to seal up thermostat housings, manual transmissions, stuff like that. You can find it at any local parts store or wal mart. I always like the black RTV. When you use it don't glob and cake it on, a thin layer will do just fine. I had to rebuild the 6 speed transmission on my drag car because the previous owner used too much RTV and it mashed out inside of the transmission and ended up getting in the bearings and also behind the shims. Here is a link to what RTV is

I have the 1258TG but am using a Brushless Hobbies ESC. No glitches, no noise. Works like a dream.

All digital servos make the sound you hear. Its just the nature of them.

I have that setup. It's not glitching, it just the servo trying to adjust it's self. If there is any stress on the wheels when you turn it on you'll get that. Usually if you pick up the front end and set it back down or wiggle the wheel on the tx it stops.

All my savox's do this. I think th aluminum case causes the noise to be louder htan with a hi-tech or other plastic case brand.

Ok, sounds like it being noisy is just the nature of digital servo's... especially when they are connected to a MMP. Thanks for all the input everyone! :)

Yeah Lake, Dont sweat it. I run them on my Tekins and they are noisy as hell but its woth putting up with. They are awesome servos.

It looks like I need a steering block and axel. Will I need new bearings too? Anything else??
Thanks

Yes Im saying no matter the ESC any digital servo will make that noise. Its nothing more than the servo finding center over and over again. Secondly yes even with an external BEC connected it will still make noise. Its nothing to worry about. Heres the deal with the castle MMPs. Some of them will run the savox stuff along with some of the other high draw servos on their BEC and some wont. They are renouned for having an extremely weak BEC. I have first hand experience with this as I have beta tested several componets for Castle and this was a known issue from day one with the MMP. Most can get away with a capacitor(spektrum or Novak) in the receiver port. Some cant depending on the unit(ESC). As some were better than others.

On another note I just ordered the Avid Spring sets for front and rear for my V2s with GHEA collars. I have been running the Losi springs which I didnt care for. The rates, especially the front were not close enough to the factory associated stuff. I also grabbed the carbon fiber rear hub towers which look better than the Associated set as they give more setup options. Was going to get the Avid 12mm clamping hexes but my Proline hexes seem to be doing just fine. I dont particular like the set screw on the Prolines but they are far better than the J Concepts clamping hexes which strip just looking at them.

Ill be posting some results once I run the Avid springs this weekend. Along with my impressions of the rear hub towers.
