I worry more about camber gain and the overall height of the arm first, and the reactive caster is secondary. The reactive caster is a good adjustment, but it's pretty specific (mid corner front end grip). The camber gain is a lot more macro.
Rob,

How is your car working after our "biased" discussion a while back?

Cheers Rob,

I've built my car as stock for now in regards to the front end, and going to have a play with servo position first, but your front end setting's is certainly on my list to try

Cheers
Ed

What spares do you guys recommend for an F104?

If running on a prepped asphalt surface, what is the setup to go with Tamiya rubber tires? Soft in back, medium in front?

Lastly, is a really fast servo recommended for 2WD F1's? I'm debating whether to order a new servo case (to hack the ears off) on my Futaba BLS451 or just run a standard servo.

i catty very little wing set i like the 3 racing, spare rear axle , diff bearings and some front arms its quiet a durable beast really i find my self building rear diffs alot after running on carpet.
with rubbers i run the standard kit tyres i have medium front and also a set of hard fronts.

i wouldnt use a really fast servo in the front it will make it twitchy the servo you have already i would just use that im using a old futaba 9451 which does the trick

i am yet to find a super soft rear spring

I have three complete spare cars. After almost two years of racing, so far ive only broken one carbon drive shaft, lost the odd screw here and there, worn out one soft t-bar and damaged the stainless steel diff shaft because i was hitting it with pliers and stuffed up the thread on it.

I've done multiple barrel rolls, hit walls at full speed and got more air in my F1 than i ever have with my Serpent 811 buggy. These things are tough as nails.

Hello,

Iíve been racing my F104 Pro with a 13.5T motor indoors on foam. For outdoors I want to switch to a 21.5T motor on rubber tires. Most of the tracks I race are low grip asphalt which is sometimes very dusty.

Iíve done a bit of research and found me a list of these tires to go:
  • Shimizu Racing (#PS-0571) Soft Racing Slick Tyre (F) w/ Inner Sponge
  • Shimizu Racing (#PS-0573) Medium Racing Slick Tyre (F) w/ Inner Sponge
  • Shimizu Racing (#PS-0575) Racing Slick Tyre (R) w/ Inner Sponge
  • Shimizu Racing (#PS-0579) Racing Slick Tire (R) w/Inner Sponge
  • Shimizu Racing (#PS-0578) Racing Slick Tire (R) w/Inner Sponge
  • Shimizu Racing (#PS-0577) Racing Slick Tire (F) w/Inner Sponge
  • Shimizu Racing (#PS-0574) Racing Slick Tire (F) w/Inner Sponge
  • RIDE (#24005) F1 Slick Front Tire H1 (Medium)
  • RIDE (#24006) F1 Slick Front Tire H1 (Hard)
  • RIDE (#24007) F1 Slick Rear Tire H1 (Medium)
  • RIDE (#24008) F1 Slick Front Tire S1 (Super Soft)
  • RIDE (#24009) F1 Slick Front Tire S2 (Soft)
  • RIDE (#24010) F1 Slick Rear Tire S1 (Super Soft)
  • RIDE (#25004) Front Wheel (BL)
  • RIDE (#25005) Rear Wheel (BL)
  • RP Racing (#RPF-RSS) F1 Slick Tire Rear W/Sponge Insert (Super Soft)
  • Tamiya (#54199) F104 Rubber Tires (R)
  • Tamiya (#54198) F104 Rubber Tires (F)
  • Tamiya (#51400) F104 Rubber Tires (R)
  • Tamiya (#51399) F104 Rubber Tires (F)
Is it necessary to heave each of one this tires to be prepared for all situations? Or is there a compound which is best for all surfaces

So had my first run with the X1 today, and it was... umm... tricky! Actually was never intending to drive it today as I didn't expect to have everything together... but the yellow wiring suits it I think

Was using a 17.5t with no boost, and Shimizu 575 Rears/573 Front.
Front;
Shimizu 0573 F1-M tire with stock insert
Black Spring
5mm ride height
1.5 camber, kit spacers
Rear;
Shimizu 0577 R1 tire with stock insert
4.5mm ride height, pod set to level
Super soft t-bar, all screws, with centre loose (can see screw moving in counter sinking)
Red spring, Losi 25wt oil, Stock spacers (3mm)
Schuey Diff greese in roll damper
Diff set to not slip, but still smooth (built with carbon balls and schumacher greese on main plate, and AE black on one piece thrust race)
Stock gearing (93/25)

To start with the car was as kit, with just diff greese on the damper tube, black front spring, Red centre shock with Losi25wt, and simply put, was really tricky to drive. I should mention I did try full width additive (FX2) for 10mins on the rear which helped, but this wore off after about 2mins of running...

Firstly, I thought it was related to the rear axle moving (I'm sure I loctited the grub screws! ) as would happily snap round when quickly changing direction. With that fixed, I tried some heavy Corally damper tube greese (blue stuff), and that massively calmed the car down into the turns (almost too much, but I figure softer front spring will help here)... however it was still really tricky on power at low throttle.
At speed, it felt pretty nice and balanced, with a bit of push, but in the slowest speed corners, it was really tricky to get smooth on the power. It would just snap, and seem to hook into the the slide... Fair enough it might be my inexperience with an F1, but I'm pretty sure it shouldn't quite be like that! Already at 50% throttle expo, any other ideas?

Also noticed something a little weird, with the centre of the super soft T-bar (right by the middle screw hole) seemingly having some wear from hitting the ground. Is this normal? or should I be looking to raise the rear ride height more.

And final question... pod droop. At the moment, I've just set the pod to be level with the chassis plate at ride height. Is this a decent starting point?

Looking forward to giving it another go when I get the 21.5t... but any other help or advice for the time being would be great!

Thanks in advance
Ed

Default New F1

Hello, returned to present my new body of F104.
A Lotus F1, of course made ​​worse by some on the forum but I had a great time and it is for me the most important.
I just ordered another from a F104W Ferrari 643 this morning to complete my collection ... RS F103, F 104, F104W.

From France.

Didnt write this but last monday i was driving in a unprepped parking lot in a track for drift cars with my front difuser. It had a very large high speed sweeper which originally i couldnot hold open throttle since the car would just jump sideways. Eventually i messed up and hit a wall in such a way one side of the difuser fell off, i then removed the other side and kept driving. Within 3 laps i was runing the turn wide open and understeering badly. I had to tighten the center screw on the Tbar and friction shock to get the car to go through that corner and still i was understeering. I honestly cant believe how well it works. I ded rebuild it in a lower angle and made an effort to smoothen it out more. Its been raining daily so i havent tried it out yet.

Hi Ed,

Try 2.5 camber front and tighten center screw of tplate. Please let me know how it turns out.

Any photos of the body off so we can see how you hold the body in place - I can't see any body posts which is very nice.

Thanks
