I´ve got a question. My car has tweak on one of the front wheels. How do you make the two wheels hit the ground at the same time?

I saw other pan car models and they have some side springs so you can change the position to make the wheel hit the ground when you want.

Thankss

You'll have to unscrew all the screws under the main chassis and the upper deck. then put the main chassis on a setup plate to see if it's tweaked.

also you can check if a front arm is not bended

First thing is to check the front springs. The front springs can collapse slightly on one side, especially if there are more right than left hand corners or vice versa. Replace the springs if they are different sizes.

Also, look at the t bar. If there are stress cracks it may need replacing. A fresh t bar usually cures all ills.

Hi,

Can anyone let me know the part numbers for BA19 and BC6 in the picture of this post?

I have these TRF shocks but the building instructions I have for the shocks are not the same and since the shocks were built with the oring inside I would like to keep it that way.

My instructions also have the oring at the bottom going in before the piston guide, in the F104 instructions its reveresed can anyone tell me why?

Thanks!

Tamiya sells a damper rod/o-ring kit. It's item number 53574.

http://www.tamiyausa.com/items/radio...d-o-ring-53574

Which 104 kit do you have? Just curious since most (not all) of the TRF shocks assemble the same way.

the F104x1 instructions have an additional o-ring inside the shock body, below the piston, to limit droop
the f104 pro instructions does not use this oring

the oring inside the body changes how far the shock shaft will extend to limit rear droop

some guys use a spacer inside the shock body instead of the oring, it does the same thing

the oring installed next to the rod guide is a seal to keep the shock oil inside the shock, you always install that one

Thanks for the replies guys, i dont have a 104, actually I have a TA06 but when I searched for assembly pictures this thread came up.

I removed the o-ring in the inside since I have these dampers on a TC.
I actually found out that the assembly is different in the TA06 manual because it is not for the TRF shocks but instead for the plastic ones, I overlooked that detail, derrrr

I swear though if you google TRF shock assembly you will find pics where the oring and the piston shaft guide are reversed, im not sure if this makes a difference but whatever I just assembled it how the pic posted early shows.

I would check and make sure nothing in the suspension is binding. Check front hingepins and also remove the friction disc assembly and make sure the pod twists side to side freely. Also make sure your droop screws at the front suspension are adjusted properly.

My F104 happened to have some tweak between the main chassis and T-plate so I shimmed it. Everything else was flat/square.

HPI SPRINT 2-Can I use a 68t spur and a 30t pinon and a 4600kv brushless motor and a 2s lipo 30C....will this pinon work for this spur? Will it over-heat my motor and ESC combo? Will it be smarter to use a 87t spur and a 30t pinon? I just mostly want to make sure I don't over heat my motor but also get the most speed. I'm new to this and this is the first forum iv aactually registered to so if I'm in the wrong place, just let me know. Thanks
Nick

I bought a used F104 Pro to race last season and I was wondering what advantage would there be if I installed the F104X1 upper deck and roll damper set. I know I should be able to install shorty lipos with it installed but will it also improve handling and performance of the car for high grip carpet racing?

i've run a f104pro to X1 conversion for almost a year on indoor high grip carpet. I've found the car more constitent with the roll damper and easier to maintain. It'll no change your car radicaly but it's a good improvement

Looking to run F1 outdoors with a 13.5 on a large track that runs 8th scale. Need some help with gearing. Any suggestions to start with?

you can start with a ratio around 2.9 - 3.0 (spur gear / pinion)
