Arrow Tamiya F104X1

Was browsing the Tamiya USA site and saw this listing for a new F104 limited edition:

http://www.tamiyausa.com/product/ite...oduct-id=84203

I've been thinking about getting into F1 RC and this is mighty tempting.

You can follow a build of this car on the following thread. Might be worth a look.

Thanks for the pointer. I searched but missed that thread since I tend to search in Title Only. Backfired this time.

Tamiya's site says the F104 Pro and F104 Pro Black are discontinued. The site says the F104X1 is a limited edition. Does this mean there is new F1 car coming [F105?] or will Tamiya just tack another adjective on [F104 Pro Black V2 or such?] to the name for essentially the same car?

I think the McLaren mp4-25 is still in production as well.

Hello i have a f104 pro that i am converting to f104x1.
I have the short upper deck with side damper and i run rubber tires on asphalt.
My car going each day better but it's very rigid as i go on asphalt and it lacks steering.
Do you think it's better i change the original 104pro stiff carbon lower deck with a frp x1 lower deck?
I run a 17.5 brushless, 93t gear, 32t pinion, 1 degree toe out and savox 1251 low profile steering servo. I have medium dampers in the front.
Maybe some helps for my lack of steering?
Thanks in advance

You don't have to use all the posts for the top deck...alternatively you can use o rings under the screws to add flex.

Thanks Rob!
And how about the lower frp deck instead of carbon one? Could it improve something?

Yes it would add flex too. The posts are an easy and cheap way to start

you can unscrew a bit the central point under the T-Bar to add more flex to the pod.

for the spring, i use medium to soft spring depending on the grip

I think I found the problem of my car.
When in the track, I have low steering. Really it has steering when I go extremely slow, but when I am going fast the car has big problems in touring, going always large
maybe something regarding the too much rear weight ?
I don't know how to fix that, I already have the Shorty pack all forwards.

The included front suspension mount can be turned and/or flipped to change the inner pickup points for camber. There are 4 options for camber: 1.0, 1.5, 2.0, and 2.5.

When you change camber, it will also change caster in the opposite direction. If you reduce camber, it will increase caster and vice versa.

For complete adjustability, I use the exotek adjustable front arm set.

http://www.exotekracing.com/f104-adj...front-arm-set/

With this you can adjust camber and caster independently.
