Interesting shock setup with the pod, but I wish it had been a conversion to a different chassis...

roche.hk 09-25-2013 03:16 AM

very interesting, looks similar the TRC Lynx 2 rear end setup with the side link up high. (please correct me if I am wrong if I donot remember the name of the car correctly.)

Nice, a floating 3-link pod with an 'A' frame bottom link instead of 2 separate links + panhard.

howardcano 09-25-2013 03:53 AM

The front end looks nice, too. I like the simple way to change the width.

tc3team 09-25-2013 06:03 AM

Looks like a cool car :nod::tire:

I would get one as a 2nd car if my club had such a class and the price was right! :tire:

Where would you get something like this?

b20btec 09-25-2013 07:32 AM

That's definitely a speed passion SP1 chassis with the SP1 front end. Love the rear end of this car, who sells this?

Apparently it's been available from several Japanese hobby shops, but to order one you will have to find one of them that both understands english and will sell outside Japan. None of the usual international stores have them. List price is $270, street price seems to be around $200.

Damn someone beat me to it...Came up with a near identical 3 pivot floating pod idea around 5 years ago but never had the resources to build it. Glad to see someone else though there was merit in the design :)

Der Dicke 09-27-2013 03:29 AM

The lower rear arm Looks way to short compared to the upper ones. Could be a Problem on bumpy tracks.

But it's allways nice to see a suspension System, that isn't an exact copy of AE (Shame on you, big RC companies).

One of the racers over here has been playing with this design for a few years.

Kinda like a TRC Lynx or predator or whatever they were called..

Is the front end on the SpeedPassion SP1 the same as the Street Jam SJF01?

Ph3nyx 09-29-2013 03:57 PM

yes , many parts are similar (the rear aluminum pod also i guess)

Cadman1981 10-02-2013 03:11 PM

Where can we get one of these? I can't find someone who sells it. Not even a copy from r2hobbies...

Integy sells the street jam drift car, maybe they will take on the F1 as well.

rccartips 11-05-2013 01:35 PM

Our 2012 F1 R/C club champ ran the SJF01. Around 1 second faster than his Tamiya F104v2.

His first runs... 19secs (video)

One week later... 17.97sec. And still going.

That is a Composite Craft Predator that some one stuck an Old School front end on. The original front is a beam similar to the old Parma 1/12TH car.The Predator Lynx II was a much more interesting car though it used the Delta style beam front similar to the TRC which is why they are sometimes confused.

Street Jam won our F1 rc club race yesterday. Rear suspension was nice, front arms looked sturdy and you can adjust roll centers.

eevul 10-07-2014 09:16 PM

I'm thinking about getting one of these and I am wondering what wing set and body works on this car? Also, what rubber tires is everyone running. Part numbers would be nice if you have them. Thanks!

JayL 10-08-2014 10:15 AM

I run the regular Tamiya F60 body, with F60 front wing and F2012 Rear wing all tamiya


tires I run same as every car Pit Shimizu 571/572

Dan 10-09-2014 09:59 PM

Jay, do you have the SJ aluminum caster block? Were you able to get it to work for 9 degrees in the narrow configuration? I noticed the upper arm (rear mounting point) is fixed....

Tried to put on an SP-1 aluminum block but it was no bueno.

JayL 10-10-2014 09:05 AM

I have have the alum block but I have been running it at 7, I have not tried 9 yet.

On the SP the arms just flexed at the knuckle for the 10, made the V collapse some, didn't have any issues , but I always felt 10 was too much. Sacrificed too much entry for exit and the only other option was 5


I'm still working on dialing in spring/oil right now. I just built a set of the bladder shocks and got the spring kit. I was going to move to caster next, I noticed the setups on petit all ran 5 or 7 so I started at 7

Dan 10-10-2014 05:01 PM

Thanks!

Just finished building the car last night. Pretty much stock except for an F104 carbon shaft I cut down to fit and the carbon hub uprights. Need to do some minor setup changes and install electronics. Maiden run at the next Norcal race, can't wait to see how it compares to my TRF.

Let me know how the bladder shocks go. I am not a huge fan of the stock shocks, but so far they feel relatively smooth.

Yep, I had a hard time getting the stock shock built right

I prefer the Speedpassion carbon axle as the diff plate is pinned and the threads are all one piece, makes it super true, much better than the tamiya or original SJ setup. Plus it is already the same size, no added parts. I run either the SP carbon or the SP steel if I need more rear grip.

I should have the new shocks ready for racing next week, I will let you know

Hey Jay what brand shocks did you use ?

Sorcerer001 10-16-2014 07:50 AM

What version of the SP plastic is used on the front end of this car? Carbon reinforced, or standard? Or did they develop a new composite for this car?

JayL 10-16-2014 09:28 AM

I use the street Jam shocks.

They have two types:
the stock ones with a through shaft no bladder like the f104v.2

option shocks with a bladder

they also have option gold shafts and option machined pistons and spacer

all the plastics for the front end are the same as the stock Speedpassion car

I swapped to the sp carbon 'b' knuckles and carbon servo holders

I left the front upper and lower arms stock as they are the best for asphalt. If I ran on carpet I would go for the carbon arms

Dan 10-16-2014 04:17 PM

Now if only I can find a SP1 aluminum steering bridge to put on. The stock bellcranks are so sloppy.

Jay prolly bought them all.

Dan 10-17-2014 02:09 AM

If you steal it from his pit box, I'll give you Yokomo tires...

JayL 10-17-2014 09:47 AM

HAHA

I didn't buy them as I am switching the SJ to direct no bellcrank, like Hara's setup. My SP F1 does have one though :)

My SJ wired up

eevul 10-27-2014 07:01 AM

Well I bit the bullet and bought an SJF01 from rc-art. I got the car in less than a week and currently waiting for body, tires and wings. I have a couple of questions though. I plan to run this car on carpet and can't find any carpet setups. Anyone have a starting setup or should I just use the ones from petitrc?

Second of all, what sort of parts break on these? I would imagine I should get some knuckles? I had an F104 pro before and the only thing I ever broke was the rear wing. And trust me, I tried breaking my F104 as I hated that car :). Any other parts that I should be stocking up on for my SJF01?

JayL 10-27-2014 09:09 AM

get the speedpassion rev b knuckles

for carpet , I know for the speedpassion which has the same front end, the speedpassion carbon reinforced upper and lower arms are better, and I would stock extras of the arms in general.

Dan 10-31-2014 10:52 AM

Installed the bladder shocks. Soooo much easier to build consistently. :) Now if only I can run my car now...
