Has anyone used the new Tamiya tires (1031, 1032) on the F104 Pro? What changes did you make from using the other Tamiya F1 tires? Trying to prepare for the TCS race. Thanks.

I have no experience with standard tamiya tires, but i've seen other drivers at my local carpet track switch to the 1031/1032 combo and pick up .5 to 1.5 seconds on a 9 second track.

I ran them at the TCS race, I squeaked into the A just barely. Depending on traction levels, I would start with a medium setup and adjust from there. the tires have good grip but arent overly aggressive.

I recently purchased a used f104 chassis. T disassembled the chassis and reassembled it, installed the x1 top deck conversion (54331), the 53901 TRF damper, and the high traction t-bar. With the adjusting ring turned to the bottom of the shock I am getting noticeable rear pod droop without anything else being installed in the car. I followed the kit instructions that came with the conversion kit, TRF damper, and the t-bar. Any help or advice??

Also any pictures of the metal upright set (54357) installed on your car??

Did you add o-ring(BA19) inside the shock? - Here are the X1 kit instructions (if it differs from the conversion instructions) -also check is the part #V5 tightened enough.
If you dont have extra o-rings just use spacer or a piece of fuel tubing etc.

The instructions do differ a little bit, the TRF damper instructions have the black o-ring (ba19) at the end of the shaft outside the cylinder up against V5, not inside the cylinder like the X1 instructions. I also see I may have forgotten a part. I will disassemble and double check in the morning and repost my findings and such. I downloaded the X1 instructions and will use those when reassembling.

I rebuilt the shock and put the BA19 o-ring on the rod inside of the shock like the X1 kit directions say. The TRF damper instructions have you install this o-ring on the rod outside of the cylinder before you attach V5. I removed this and with the shock adjuster turned all the way against the stop, I have no rear pod droop at all, which I believe is the way it should be. Thanks for posting those instructions fastvee.

No problem.

I do like some droop , but it is easy to adjust with the #V5.

Now put softest spring you can find on that shock and go drive it.

(I love the gold spring http://www.tqrcracing.com/shop/produ....asp?p_id=2364 ) , if you dont have it and drive on asphalt I suggest you get one. I use 25-30wt oil with that spring on med/low grip asphalt

Default A couple of questions

I am trying to understand the possible adjustments for the front end on my X1. I have watched the the youtube vids from rc F1 blog guy and that has helped. I am messing around with front droop and from what I can see there seems to be and inherent amount of droop in the front upright area. Just wondering what the benefits/drawbacks are to preload the spring.

I ran the car for the first time last week at a TCS race. I found out that I like to break the C5 plate. Seems the original one lasted longer than the replacements. The original looks like a fiber reinforced piece, the others look to be plastic only. Just wondering what other peoples findings have been. Is it helpful to get the aluminum upgrade parts for the motor pod area? better durability?

The car is box stock except for the adjustable uprights. Tamiya (54357)

I set the droop screws on the front just enough to take out slackwhen the car is at rest- so the upper arm sits almost on the screw. I have found that in a tumble, the pivot ball can pop out of the lower arm and completely tweak the front end. I never use tweak to pre-load the spring.

With the lower pod plate, you are better off with plastic, it's cheaper. Both types will break, the graphite piece probably easier. keep a spare with you.

Ok another question.
I have the 3x35mm Titan Turnbuckle (53528) installed in place of the standard rods on the f104. I see Tamiya makes 2 turnbuckle wrenches, 53602 & 42122, which would be the proper one to use with the turnbuckles I have??

Could you suggest a different brand wrench for the turnbuckles if you don't like Tamiya??
