My Hyper 9 is on the way but now I have a question about the caster..

Has anyone found a way to put less caster in it for high bite tracks so
it won't push???

The reason I ask is I went over to West Coast R/C the day after I ordered
it and guys that ("use") to run the Hyper 9 said the reason they quit
racing the Hyper at WC was because they did not have the option of
castor blocks with less castor and with the super high bite at WC they
never could get it to turn at WC.

One guy told me Kortz raced his at WC and it turned, it also had less
castor in the front but the parts were not avalible to everyone just
Team drivers...

I'm sure with the Hyper 9 being out so long someone has found a castor
block off of something that can be made to fit the Hyper 9 to give it less
castor...

Thanks for any help as I'm planning on racing at WC as well as my home
tracks and it would be nice to be able to tune for high bite...

I just talked to Kortz and his front set-up is the same as what's on the stock car, no special c-hubs, roll centers or arms. He run the the thin sway bar 2.4 on the front and a 2.6 on the rear. I didn't too far into details on more of the internal set-up but I drove his car one time at OC and man that car turned.

I don't mean to bash on you or try to prove you wrong, Chuck, but your claim that people stopped running the 9e because they "could not get it to turn" sounds like an unfounded rumor to me. Not knowing those people, I can't say anything about their ability to set their cars up to handle like they want. All I know for sure is that the 9e undoubtedly will handle and turn as good or better than you will ever need it to, with very little effort on your part. You spent $400 on a toy car that has all the potential and more to do what you need it to do- use it! All you have to know is how to set it up.

I've never had steering issues with my 9e that were directly related to the front caster angle. There are plenty of things you can do to get more steering out of any car. Let me share with you one super-easy, tiny change that I just made on my 9e which has made a HUGE difference in my car's ability to rotate through corners. Switch to the 2.5-degree rear toe blocks. As soon as I did that (coming from the 3-degree blocks), my car had almost too much steering. It is very precise now, to the point that most novice drivers would call twitchy, but works for me. I can make the rear end of the car swing around at literally any time with the 2.5-degree toe blocks. It's scary to imagine how much rotation it would have with the 2-degree blocks.

I'd also like to say two more important things about my setup:
Tires: Indy RC World, Garland TX (indoor, hard-packed clay, cool temps): AKA Enduro, Super-soft
Diffs: 7-7-5

I've let guys who are faster than me drive my 9e at Indy, and even with the 3-degree toe blocks, they said my car had plenty of steering. I'm talking guys who average 1-second faster than me -every- lap! I'm no pro, but I'm no slouch, either.

Thanks for the info. I never took it as a bash at all"

I've only ever raced at one other track with traction like WC I mean when
you corner marshall at WC your shoes try to pull off your feet, if your not
careful they will come off.

When I ran at the other track years back we all took all the castor out of
our cars to get them to turn because the track was like racing on VHT
(GLUE") I'm talking turning free so they role through the center without
binding up scrubing speed. You can make anything turn tight loosing
speed through the center...Thats easy anyone can do that"

So when these guys tell me this was the reason their not running the
Hyper 9 anymore at WC,all I can do is take them at their word because
I've seen this before.

I don't have my buggy yet it should be here today or monday so without
driving it all I can do is wait & see. In the mean time I'm just covering the
bases asking this question in case I need a plan "B"...

Kortz is one of my favorite drivers to race with at any track, he's not a
PITA like some team drivers tend to be at races. He's very friendly
& helpful to everyone and he drives clean with you no matter who you
are. So if he told you that I'd say he's not BSing you and the buggy will
be fine without changing castor.

I asked the question to have a plan "B" if it was needed once I start
racing my Hyper 9...

Thanks for you help...

I just finished my build at WCRC and stock out the box setting but with 7-7-5 diff oil and 45-40 shock oil I have TO MUCH steering... I love the feel of the 7-7-5 the rear is planted but the front turns like a 2WD buggy...

I do need to tweak the setup a bit so once I get a practice day I will post any changes.


Also Gold Jconcepts bar codes with the larger outside tread facing out.

That must be a level of traction that I have never experienced. Are you sure that all kinds of tires were tested? My logic is suggesting using a tire that deliberately does -not- hook up on that kind of surface- like, a hard-compound, large-pin tire. Crime Fighter M2s, AKA Crossbraces (Hard), JConcepts Crowbars, etc. Had they tried that?

its not bad out of the box.. if i recall i had something fall off... it was a screw that was in aluminum... a bit of blue loctite and it was mint... i forget what went loose on me.. it might of been the screws on the bottom that go into the steering posts.

Due to Hobao shipping air freight (Thanks Gosh otherwise its 6-8 weeks ocean) the diff oil thins out and leaks so you will need refill all the diffs. I checked mine right out of the box and there was only residue left.


I have the MMM w/ 2200Kv on a 4S and WOW I hit 37mph on WCRC straight normal is 33-34, It's an awesome system if you ever plan on running big and little tracks, I run 80% indoor and 100% outside.

Since you don't know if the little Chinese girl who put your car together smoked opium or turned tricks the night before she built it, you should tear it completely down and re-build it...The Hyper 9 that I built for a friend of mine needed just that, as did the Hyper 10tt I just built for myself. However, the Hyper 9e is a joy to work on and I look forward to putting you into the wall when it's done.

Tear it down and see how good it is first-hand. Of all the cars I've owned (including Losi 8ights, Associated RC8s, and Mugen MBX6s), the 9E is my favorite when it comes to working on it. It's so easy and intuitive. Nice low parts count, no unnecessary screws (HATE unnecessary screws), smaller parts all around, and just one dog bone in the middle. I do not miss any of the brands of car that I ran in the past.
