I remember a wtf moment as well

Also those look like they might be the upper balls for a lightning 12... Maybe they should stop calling every pan car a lightning and the packagers wouldn't get confused

Yeah, I installed that part without the spacer and I was like..wait, this doesnt look right. Went back to the manual and it didnt say anything about the spacer, even the parts list didnt list out that spacer too. Looked at the picture and noticed its suppose to go there.

If you look closely, the F, FX and 12 all have different part numbers. The shape and form of the ball is different as well. Hopefully they give me the right part

Come to think about it I had the same issue with missing that spacer too.

My son had his first drive in the FX (and a first drive for any F1) last Friday. Lots of f1 learning to do.
Loosened the diff to be just right stopped the car from hooking on power, set some negative steering and throttle curve made the car drivable.

One of the other drivers suggested thicker lube in the side tubes. We will try 100k instead of 20k.

I would not recommend the Serpent Sf2 front wing as it lasted for one race only. Another car and ours had the same issue.

I heard of the same issue with that wing. The first batch seems to be made from a weaker material and would break on the slightest tap, but supposedly they revised the wing and its made tougher.

I did some testing with the serpent wings this weekend on carpet high bite, it feels like the front wing generates too much downforce in a high grip situation and caused the front loaded tire to dig in too much. It is also not a wing to use in a beginner situation because it is not as strong as other wings. I think it would be more valuable to run on asphalt where the grip will be lower and traction rolling is non existent.
The I tested the rear wing at all 3 downforce levels and it felt very positive. In the end I went back to the f60 front wing and 3 racing rear wing. These two wings have been the most durable wings I have tried. As well they are performers. I think maybe the serpent wing could be used to greater effect if stiffer springs than Vbc black could be installed on the car.

I have sold 5 of the version 2 wings and of that 1 customer broke his on the second day but he was having problems with the car and crashing a lot.

Took the car out for its first drive last night. Wow...big difference between the LightningF. The car turns a lot better and I have more confident driving than the F.

One thing I noticed is that you can handle the car. If you turn really suddenly at the end of the straight, the rear end comes around sending you into a spin. If you were able to prevent it from spinning the car snaps back pretty violently upsetting the car. I had to bleed off all speed and roll gently into the throttle.

It caught me off guard a few times and Ive drove into the dividers twice. But the temperature suddenly dropped a 8 degree last night so the track was pretty cold so that might have an affect on the tire's grip. Also, one of the side link snapped in half probably when I hit the dividing wall. Kinda surprised how brittle they were. They were like noodles on the LightningF.

I got the new uppper king pin balls and infact feels pretty loose in the cups. I dont notice the play that much tho. Its working pretty good.

On an other note, are you steering arm binding with the kingpin? On mine they dont move up and down freely. The hole seems to be too small for the kingpin and Im tempted to drill it out so it slides up and down better.

Interesting
They are the same links from the lightning f it's possible the temperature difference made the link snap? Plastics don't like cold
A question for you though, did you add a shock o-ring under the piston to lessen the pod droop? You want about 1.5-2 pod droop
Also are you running the kit springs?

I used a 3mm arm reamer on my steering knuckles to help them move freely but you shouldn't need them as you can use the set screw to lock the knuckle to the kingpin.

Im not sure if they are the same links or not. Dimension wise they are, but the material seems different. I took the ones off the LightningF for now before I can get some replacements.

I didnt add an o-ring under the piston. Maybe I should. I was wondering myself how to deal with the droop and thought I need to shorten the ball cup.

4mm for carpet 5 for asphalt also do yourself a favor and use aluminum shims in place of plastic where ever you can.

Another update from my second run at the track. The side link broke the same way and same location as last time. I was cutting it too close on this one corner and curbed the car. It traction rolled and broke the left link, and popped the right link. I guess I have to work on my driving skills a bit.

Also, I took your advice and locked the steering knuckles in place with a set screw. I was having a TON of slop before but locking down the steering knuckles improved that by a whole lot. Im still getting some play in the upper and lower king pin ball as mentioned by you, but its miles better than not locking down the steering knuckle.

Default Fx frontend on LightningF

Anybody know if the FX frontend could fit on the older F car?

Use the side links from the AE 12r5.2. They are a little more flexible and forgiving when you hit something.
