When Pro1 built a Gn with rear a-arms.Did the dog bone go through the shock bottom?Just wondering,

ED

a-arms attach to axel bearing carriers ( top and bottom), shocks attach to the front and/or back side of the carriers. dogbone not in the way of shocks.

a-arms attach to axel bearing carriers ( top and bottom), shocks attach to the front and/or back side of the carriers. dogbone not in the way of shocks.Here is what i mean.The dogbone goes through the shock.The is an MCD shock.I remade the plastic tuning fork end with 5052 aluminum.

How many track bars 2 or 4?

Thanks ED

One picture is worth a thousand words

One picture is worth a thousand wordsMike Thanks, Not what i had in mind.I only been sugesting it for a few years.How did it work? Are the arms the same as the front.They look short.
If so 4 arms would be cheaper to put on the car.Than 2 front arms and the 2 the trailing arms.

What do you do if you want the shock in front,Mount it to the track bar?
How would the shock work if over the center of bearing block?Guessing the bearing is about 1.75 to 2.0 inches long.If a little shorter the arms could big longer.Maybe to much rebound if longer.Track bar sets the rear steer.

Mike not picking on you just ideas.You,Jim or the PRO1 did a good job.Its good to see new ideas in 1/4 scale.

Keep up the good work.

Here's another shot!

From the talk that I had with Greg Hilber, they love the new car and the set up is easier than the 05 Pro1 and the car rotates through the turn better, which is where most races are won. They have been successful with the new car and that is what counts. I will move up to the new car but it will be late in 09 when I do.

The Car & Company belongs to Jim, so all the Kudo's go to him and any who race any R&D for him. In this day & time it takes a good set of Gonads to take a successful car turn 180 degrees and go in a completely different direction.
From what I have been hearing it will be worth it.

MikeMike i agree with you.about the R&D.If one follows the same design year after 1/4 as the whole can't grow.The newest product to hit 1/4 scale was the trailing arm in a sense.Last couple of years the new front hub.Larry Cross came out with the predator.Something a bit diferent.Not sure how it runs.I don't race as most of you know.The thing i see the motor keeps getting bigger.Which does wreck havoc for the QSAC board.Todd is doing all he can do.To keep his products in line with the growing HP.

There are alot of smart guys out there.Wiiling to try new ideas.Why don't they work with the manufacturers.Instead of worrying about their wallets.

My ideas and designs are out there.I rather sit in the back ground.One day i would like help R&D for a manfacturer again.

Who released the pics?

What pictures?

The shots above.

You mean the shots below. Jim sent them to me. This car was produced last year and making laps and winning at MPR and races at Freddies in 08.

Aah, I was under the impression it was still under the radar somewhat?

Lord no, The Hilber's have been running them for a while. Jim's wanted me to jump on board but I'll need to wait to at least June this year.

Aah, I was under the impression it was still under the radar somewhat?
I think your right Tim

I'm wasn't real sure. I saw one, but was asked not to mention it or disclose any details. Being one that races a Pro1, I have kept it to myself for a couple years now. :)

Hopefully we'll get see the car at the NCS race @ LPR?

Guys i designed a car for Danny's 1/4 scale with a-arms in the rear a couple of years ago.one could adjust the track bars without taking the body off.He wanted the design of the QSM.When he found out i made the frame.Larry always treated well.So i designed Danny a whole new car.

Mike like you said a pic is worth alot.When i saw a couple of pics.I could see why they could not get the QMS GN work.

You will Greg said he was trying his best to get down here.

If he can't make it, tell him to send a car. One of us will be glad to track her!!!

BTW, I read on the Pro1 site that the car has won a couple races... looks to be Sportsman. Has the car been raced in any NCS races and if so, has it seen GN competition?

i think the first race was freddies 500 from what i heard

Well Guys,
I removed the pictures because of the problems I may have caused Jim and Pro1. Yes, I should have dropped him an email to get his offical okdokie!

Jim said Since the car has whooped some of you already it didn't really matter. So, I didn't screw the pooch on the New car. For those of you who wants the next greatest thing, yes it will be available in February. So the rest of you, "Be afraid, be very afraid"!

Puts new meaning into "Race One or Chase One".

Just a question a gray area for QSAC.The rules i think do not say anything about a car with a-arms in the rear.I wonder if one could use a long and short arm.

ED

I hope someone is building one to run in the Super Truck class. I would like to run against one. I think it will be a hand full on the setup:freak:. Just my 2 cents.;)Well Guys,

We saw the car at Ingalls for the Tri-State race and then at Freddies . It appeared to be very stable on the track . If you get a chance to look it over, the rear suspension looks much healthier than what we're all used to seeing . According to the rules if I'm not mistaken all it says is the cars have to be independant suspension .

The rear a-arm car is a good idea . A freind of mine made one two years ago and has been testing it since [NOVA], When I started rc we use old rc10's converted to on road [ rear a-arm ] plus a rear sway bar . The only draw back on this is the belt drive on the left rear , The wear on componants will be What i would be watchin for , Other wise from what i have seen,,, it looked good .What is the weight of the car , Robert

Randy not picking on you.The rear a-arm is an independent suspension.The GN has a trailing arm. That is called an I.R.S rear.A cantilever suspension was not allowed.
If you tried an I.R.S. the Sprint that would be iileagal.Sprint has to have a straight axle.I could be wrong.

Ed you're right , sprints have to have a straight axle in the rear , what's the difference if you have a trailing arm or a four link so long as it has a straight axle ? Just because a sprint has a trailing arm it doesn't mean it has IRS .

Randy you right.I think i did did not explain it right.I never was any good in english,And a very rare disease called Lymphomatoid granulomatosis in my brain.I just meant if one goes with an I.R.S.in a sprint it would not be allowed.

I started this thread just to find out.About the pro1 rear a-arm car.How it worked.The next thing guys are getting into trouble,by putting out a pic.

Sorry to Mike for getting him in trouble,and to you i was not picking on you I knew the IRS would work.I am glad that someone is trying it.

ED

You are right ed. The thing is a lot of guys don't know setup well. They are a lot of good drivers out there but they are lacking the setup skill. They are a few good setup guys that lack the driving skills also. Like ME. But I'm still working on that part. My dad always said nothing beats seat time and its true. The more you race the better the car will get and the driving skills.:thumbsup:Jeff thats what seperates the boys from the men.Setup and driving:wave:

Mike thanks,I am glad that all is well wih Jim.

Do you have a pic of the whole rear.i know the 2 pics before were from each wheel.If you want just e-mail me. If not ok.

I think the shock was mounted to the bearing block.What handling change would there be if mounted to the lower arm.I know you used parts on hand.For the R&D.If it could be mounted to the lower arm.It would have to be redesigned.
With the a-arms in the rear.The car could have more adjustments than the trailing arm.This would leave (Jeff out just kidding).Toe in would be a lot easier than using washers or different lenght spacers.
Not sure if caster could help with tracking.

The reason for a pic of the rear.It looks like the centerline of the rear tires are even.We all know one should be head of the other.

ED

Mike, Yeap you hit the nail on the head. Nothing beats good ole luck. I hope I have some a lot this year with these sprint guys. They are tuff!!!:thumbsup:Jeff: You forgot good ole LUCK:thumbsup:
