On the F1R thread, someone posted a pic of a Durango droop screw that is 3mm with a head on it. It also has hexes on both ends so it can be adjusted from top it bottom with a 1.5mm

My question about the Extoek front end might be better addressed on the F1R thread, but I'll ask it here. When the F113 came out, it was said to not be legal for UF1 races due to the shocks being outside the bodywork (as well as other factors). I've wondered how this front end is legal for UF1 when the F113 isn't.

my axle was not straight.




made a tool to measure it.

after some hammering made deviation from 1/10 mm to 1/100 mm

the steel is quit hard , needed a lot of force.

I got the SJ body and very happy with it..theres no cutouts for front arms so just be carful here but its nicely detailed and cheap and comes with 2x diff noses plus helmet. I also got the rear diffuser .
Was thinking about trying the SJ F12014 body but the SMP48 (yours) just looks so simple and clean (also easy to paint).

It's not the fact the F113 shocks are outside the body, there's nothing wrong with the F113 shocks. In fact the shocks are one area that's legal. It is illegal because the wishbone mounting points are outside the body, and that it's 200mm wide.

Thats right they do a more modern body but i like the 80s/90s bodys and the modern i think comes with seperate noses which can look a bit stuck on.

To make matters worse it bounced & skipped over any bumps on the track surface making it unstable & almost impossible to drive.
I was almost ready to give up on it there and then, trying to drive a car out of the box that had horrible handling, and with the memory of the terrible build still fresh in my mind, I had the ebay app open on my phone ready to sell it off for what ever I could get for it.

But......

A friend who had also been watching it, suggested a different weight oil in the shocks to address the skipping issue, and after changing the oil the car was a little better to drive. So what next? my thought turned to spring rates, and decided to try the medium soft springs, the result was also an improvement in handling, but still very nervous going into the turn, and quick corrections of opposite lock was needed.

The next 2 changes also improved the cars handling, one of them I just thought of doing for "shits & giggles" being reducing the amount force of brake in the esc from 75% to 67%. The other change was going 1 tooth less on the pinion gear as it was a very warm day and the motor was coming off very hot after the practice sessions.
After those changes, the car transformed into something that was very fast, very smooth, and had handling that almost resembled a touring car with the same motor (21.5t).
During further practice runs the lap times came down to the point that I was demoralizing some of the 21.5 touring car drivers, by not only catching them, but also passing them on the outside, & turning into the corners faster than they could.

Later in the day I had the chance to pace my car against evochick's, and 2 things were very apparent from having the battery mounted up front.
The first was that my car was "pushing" out of the tighter turns which meant my exit speed was slower, and the second was that evochick was able to get on the power quicker out of the tighter turns with having the extra weight over the back wheels.
The front to back balancing point on the 2 cars were not much, but the result was greater, so before the race meeting on Sunday, I'll be swapping the battery to the back, and the esc up towards the front of the car.

At the end of the day I was a much happier person, because I felt less like I had wasted my money on a car that I perceived was bad. One thing I did notice as the handling of the car improved, is that I had to be more "aggressive" with my driving style because it improved when I did so. Sure, it's not perfect, but I doubt any car is, and my driving is very far from perfect too, but now I feel confident it will improve when I make the changes to it, and that it will be even better with the bladder shocks (when I can get them).

Another point I want to share is that the car took some very hard hits today, including getting the front wing wedged under a bolted down metal track barrier, which took the use of a crowbar to get it free and nothing broke, which is always a good thing so there is a degree of durability in the car.

So, hopefully the racing gods will be kind to us come Sunday, and I'll be able to keep up with evochick to make it a 1 & 2 for Street Jam on the day in the F1 class.

Regards
Rob.
Hi Rob

Could you please share your setup? I am curious about the shock oil, etc.

And then for someone who can answer. which is a good starting oil with the the type two shocks and the 4-holes machined Pistons? I am using 700 now and I a pretty satisfied... But I was wondering what people are using with the machined pistons

Thanks a lot

I used the setup that evochick put up in this post - http://www.rctech.net/forum/13744959-post129.html

The two differences from evochick's car to mine was a different body, and front wing. I was using a low down force wing, which meant I had to brake harder to turn into the corners, which scrubbed of a good amount of corner speed.

Our StreetJams debuted with a 1st & 2nd at an event yesterday. At first the car didn't feel any faster than my old car, but once I changed the settings to resemble as close as possible to the above setup sheet, the car felt a lot more settled & smoother to drive.
Also during the course of the day, the car underwent some "durability testing" from me crashing it from my own fault, and crashing from slower lapped cars suddenly deciding that they wanted to drive into me, but the car stood up to some sizable impacts so good news on that aspect.

Is it quicker or better to drive than my F113 - I'm not totally sure at the moment, I'm still not 100% convinced that this car is the best car for me & my driving style, so I'm going to withhold judgement for now until I race it a few more times so I can gain a better comparison.

Regards
Rob.

Rob was a little unlucky in this first A final, but bounced back with good results in the next 2 finals. My car is the yellow with the white wings out in front

Yesterday 1rst try-out with the Streetjam.
Car feels realy good on the carpet track with the Ride R1 tyre.
Rear is a bit bumby (need harder oil)
No timed laps yet, but the car is verry forgiving and predictable,
like someone said before like a touringcar.

This is my steering solution:
