When building the shock which piston do people use for carpet tracks? I would guess the 2 hole but I'm not really sure.

On asphalt (like the Tamiya track) I don't see the need to run the car lower than 4.2mm at the front. You need some decent clearance to let the front end roll some. IMO If anyone feels the need to run 3mm on carpet adding shims below the carbon top arm is no big deal and it's super easy.

I ran my F104 V2 for 3 months straight at TQ over the winter UF1 series. The car was good and still is a good car. I only have 3 weekends with the TRF101 and it's proven itself and I have yet to scratch the surface of trying stuff. Today I tried "in-line" steering VS. "trailing". Both set ups were good! Trailing however makes the car drive easier and I did not loose pace. I was able to do my fastest lap, beating it by a 100th with trailing. So both are quick, but to me trailing feels less sensitive. Some people may like sensitive.

Also, the TRF101 like the F104 V2 is sensitive to "toe" angle. You have to run some toe-out to get the car to be stable. Some of you I notice run straight to "toe-in" and your cars behave very erratic. I run between 2.0 to 2.5 degrees of toe-out.
With the shims under the axle per the manual, how much front droop does the car have?

Also, are you using the manual suggested spacers for the upper arm screws that thread into the lower plastic arm?

Had the car out on a asphalt track past couple days and the car handles great....the only issue i was having has been stated already in this thread.......everytime i was coming on to the straight it would immediately pull to the left and almost donut around ....either im applying throttle too early or i was thinking maybe i gotta look into the tension in the diff....but unsure if tightening the diff up will get rid of this problem ?....i will hit the track again this week and play around with the diff....unless im looking in the wrong place.

How well does the car roll in the front? Do you have the stiffening screws in or not?
Don't know if this is the same as everyones else experience, I set the front back up per manual then took the e clip out and put rubber orings in place of the two metal washers in the center of the top arm. Using gold springs in the front by the way. This set my ride height at 4.5mm using pit tires on exotech +3 wheels. For first run I loosened the top screws and the font felt a little dead and lazy in the corners, this on med. grip carpet. Tightening the screws back down made the front a little more reactive but still a little numb on corner entry. I'm hoping that if I can find a way to take a little of the castor out of the front I can gain some more turn on entry unless someone knows of a better way. Will have to try the silver springs in front but when I first put them on I had a ton of droop in the front almost like the springs were too soft.

I played around more with the front arm shimming. I built the car to kit up front, minus the kingpin e-clips, and found the F2 plastic bushings. They're 2mm FYI. Per the kit, I'm at 5.5mm front right height. I added 2mm shims all around and down to 3.5mm, which should be almost perfect for carpet.

Will be able to test Saturday and race in the 2nd round of the Texas EOS series on Sunday. Going to be interesting. New radio + new car should be fun.

Just a heads up. Check and make sure your front wing is not rubbing the track at 3.5 ride height. Mine was diggin in hard during cornering at that height so you may need to shim the front wing up a little. Made the front tires lose traction going through a high speed sweeper and went straight into the wall at full tilt. Good thing I had a couple extra bottom arms laying around from the old 104.

I'm going to be running the older 104 Pro body and wing set, which is much more narrow than the 2012 front wings. This should proabably keep me from having that issue. Never the less I'll watch out for it. Thanks.

I'd try loosening the diff 1/32 - 1/16 of a turn.

I was there. He was using foams, with Yokomo ESC(HW3.0) and Corally 21.5T. And no Gyro...

I taped all his qualify on touring car and F1 as well.

He came back to HK for R2 race a few weeks ago. But we got a bad weather during the race day. So the race was cancalled.

I have attached is his setup and ESC setup for you guys review.

Default Mounting ESC

Hi.

Where is the best part to install the ESC, in front near the servo or at the back near the motor?

Thanks.
