What are your feelings about the 9380 compare to the 7950

Re: Beerman's Berg: RcBro/ Secret Agent Chassis
 

Seems smoother to me!(as compared to the new 7950 on my DA). They claim it's more efficient, Plus it's quiet, none of the noise trying to find center and such. Power is @ the same. They do take a 25t(Futaba)arm, maybe the companies will get together and unify all the arms. Also it has 3mm threads holding the arm on! This is my first brushless servo and most likely won't go back.

Who cares how well it works, it's RED! And matches your truck! "thumbsup""thumbsup"

That rock is insane looking. Rig is looking good too!"thumbsup"

Re: Beerman's Berg: RcBro/ Secret Agent Chassis
 

I might have to try that servo just because of the color.... Killer!!

Beerman's Berg: RcBro/ Secret Agent Chassis
 

I made a few more changes that I'm very happy with. First off I made new front lower links. The reason for the new links was to get more steering without the tire hitting the links, It turned out great. With the Dlux shafts I'm able to get maximum steering without hitting the links. The tires ever so slightly touch the end bell of the motor so my clarence is amazing. Also had Tom make me some Carbon fiber upper links. They're extremely lightweight and very strong, very happy with them. The front upper links are 115mm and the rear are 155 mm. I also made a change to my form set up. In the rear I'm using the 5.25" with the medium outers and so far happy with the results. Here are some pictures of my links and link placement. With the link placement the way that it is it gives me a neutral set up with a slight touch of anti-squat.

As you can see I can get Maximum steering without hitting the links and these are Dlux shafts.

Great steering! Getting into the front lowers is a problem I've I had with much less than 70* steering. I've seen a build or 2 with carbon lowers. Now that you've held them and installed the uppers, would you trust carbon lowers?

The concerns I have with having the carbon fiber lower Links would be the rock rash. Not for sure how much they can handle. Plus for me I don't like having straight lower links.

Re: Beerman's Berg: RcBro/ Secret Agent Chassis
 

If I had any skill using this phone I'd post a pic of the bent carbon lowers I'd seen. Pretty slick but I'm with you, they would have to wear pretty fast. Perhaps not worth sacrificing the strength in some places. Great thread with crazy nice parts beerman. I've enjoyed!!

I have never seen the bent lowers, that would be sweet to see. The carbon fiber I use is cheap to buy. It cost me 5$ to make the uppers so I would be ok if they don't last to long.

Re: Beerman's Berg: RcBro/ Secret Agent Chassis
 

I don't think the carbon lowers would be any benefit. First off you have to buy a sheet of 3/16" thick carbon (not cheap!) And I don't think they would be any lighter than the 7075 aluminum rod. The straight uppers are lighter because they are hollow.

I can't wait to drive this truck around this week! Maybe we can get Jason to bring his GoPro out and put together a video for all you followers!

Re: Beerman's Berg: RcBro/ Secret Agent Chassis
 

Video would be sweet.
Just looking for points of view on the carbon/light weight stuff. I've never ran anything but dlux ti lowers. Going to try delrin for the first time on a sporty build. Thanks for all the input guys! Hoping for that video footage soon!

Some pictures showing the stance, I love how this crawler looks.

Re: Beerman's Berg: RcBro/ Secret Agent Chassis
 

Looks great. What hubs are you running up front? I'm not sure if you would have room, but if you mounted your shocks on the inside of those tabs on the axle it would keep the tires off the shocks.

Again... great looking rig. Want to see some video "thumbsup"

I'm using the slw 475 up front and the 350 in the rear. I did mount the shocks on the inside but the crawler is more stable with the stocks mounted on the outside. The tires do make contact with the shocks but it doesn't seem to have a negative affect, the tires don't get wadded up in shocks. Years ago I had some BB and the tires would pop off the spring retainer, and with this set up its nothing like that.
