F109 beat off all competition in a 5-day series spread over 5 months that I race in. IMHO the F104 has better scale looks but its true to life - it has skinnier tyres and the battery is placed down the centre of the chassis to achieve this. Its a very ncie looking car and when setup will run well on carpet, but the F109 will beat it with ease. However, it looks nothing like an F1 car IMHO.

you ever see a 109 with a tamiya or chevron body?It looks quite nice-IMHO
and still performs as a 109; the stock body does leave a lot to be desired.
A guy I know is going to bolt up a 104 front end and run "skinny"tires.I don't think it will hurt it too much.And yes I have both-I prefer the 109 on both surfaces.

The f109 shell can look very tidy and scale check mine below



I have both, I think the F109 is great value and it is the faster car. I run brushless 13t in my f1's on a tight small circuit. (there are some vids on my blog)

If you think the F109 looks nothing like an F1 car, then you haven't seen Corally's F1 car.

I like the soft rears pretty much everywhere I run it, even on carpet so far.

They get the "death groove" quickly tho, the foam shifts to the outside edge then the inside edge gets the groove worn into it.
You'll see but the tires work pretty nicely, especially on the very first run.
After that they settle in to a consistant tire for many good runs, then the groove.
Fresh set of soft rear and kit/medium fronts and it doesn't get much better than that so save a set for when it really counts and practice with the "scuffed" sets.

I stole Lunsford turnbuckles and Losi cups and balls from a retired buggy.

I know that RIDE, Shimizu Racing and RP Racing also make tires for the F104. But I'm not sure if HPI tires will fit on Tamiya wheels.

I've been calling the kit rubber tires medium cuz the option rears are soft and the option fronts are hard.

When I ran the option front hard tires with the option rear soft tires I had almost no steering but the tracks I hit have pretty good or even great traction.
Parking lots will be the difference I'm sure, unless Charlie B is layin down the magic traction sauce. His parking lot circuit tracks are hooooked up!

The hard fronts work better for me with the kit/medium rears, better balance but I also find the kit/medium rears don't have enough traction for me in most situations.
This may be the hot ticket on super hot surfaces, harder compounds but when it was pretty friggin hot here in So Cal at the Tamiya track (130* track temp) I still was quicker with the soft rear/medium front combo.

I think the idea was to use option tires to balance the kit tires on either end.

Option front/hard with kit/medium rear or

Option rear/soft with kit/medium front.

Anyone got change for a nickel?

Would front spring rates change the handling on hard front tires? I use windtunnle baby springs. So maybe using a harder spring rate would keep the front tires planted. Or would that just compound the understeering problem?

Default Your default gear ratio

Hi guys,

Quick question, what is your preferred default gear ratio when you go to any new track. Assuming that the track is moderate in size with 50 - 70m straights and normal technical sections.

The stock ratio for F104 Pro is 104 spur and 25 pinion which gives 4.16.

I notice most guys at my track are running around 5 and above. ie. 105/21 or higher ratios.

Give give me your ratios will suffice. Thanks a lot.

HPI tires will deform when mounted on Tamiya rims, Tamiya rims are larger in diameter...

In order to use HPI rubber properly on a 104 you need RIDE wheels...
