Brca have released their f1 rules for next season and it's 21.5t open esc.
180mm rubber or 200mm foam.
It's open esc! So boost will play a big factor in top end speed.
I'm yet to get my 21.5 any suggestions which one to get?
I'm running a sp gt2.0 lpf esc.

I'd start with a rollout in the 50's and temp after a couple minutes. As far as tires, I'm guessing asphalt outdoor? I'd check with the local racers and see what is hooking up well.

Been running to those rules other the Ardent winter Pan car series, and it has gone very well.

F1 is a great class as it is possible to over power the available grip and make the car hard to drive. So boost is less of a factor, and particularly so on tighter or smaller tracks.

I've seen most of the major motor brands available in the UK run as 21.5 motors so far. Personally I run the GM 21.5 as I know those motors well and know they can handle the heat well.

Shout if you need advice or help...
Mark

You said foam tyres on carpet with no additive. And a 13.5 with 2S is going to be quick - I've run 21.5 both with and without boost, which is pretty darned quick. You will have your hands full I suspect

Soft rear tyres and harder fronts would make sense. I'm still running F109 kits tyres which are medium fronts and soft rears. Might be worth looking at the Exceed tyres which are also available via the UK Exceed/Serpent importer.

It's official. F1 will be an official class at the 2012 Carpet Nationals at Mikes Hobbyshop in March! I can't wait. Home track, favorite class, excited.

Thanks Mark, well actually it will be 2S Lipo 27t brushed just now but if I start racing it again on a regular basis I will look in to brushless for it. I thought 21.5 might be a bit slow so I would of went 17.5t like the WGT rules....

Anyway, tires. Yes I looked at the exceed's, obviously soft rears but with medium or hard fronts? I always used to run blue front, green rear (with additive) but their is a quick turn around at the club so if I could get away without the sauce it would free me up on the night.

Go watch the video of the F1 class at the IIC...21.5 isn't all that slow

+ YouTube Video

21.5 F1 is faster top speed than 17.5 TC. Both running blinky. Locally TC is about .5 seconds per lap faster. But 4wd will do that for you. When I first brought up running F1 to our local racers they thought 21.5 would be too slow as well. They think differently now. It's become the 2nd largest class at our track.

Same here.

My F1 with 17.5 boosted (72mmpr) is doing 80kph(50mph) no problem on a big stretch! but I wouldn't get to those kind of speeds on an indoor track.

I imagine 21.5 is great for indoor carpet tracks with an F1..

I'm trying to figure out which 21.5 I want as it's the BRCA nationals motor for next year..

Although i'm using my 17.5 boosted at my local outdoor track, silver can there feels a bit like it's standing still on the back straight which i'm guessing is near 21.5 speeds..

Default Moving from TC to F1

If I wanted to race F1 competitively then I need a plain Tamiya F104 chassis because it is 190m wide not the f104w or F103? Correct?

I have an 3 year old Novak GTB and Novak 21.5 motor plus digital servo and radio gear from my TC I should be able to use, correct.

So basically
So go to Tower or Stormer and buy Tamiya Ferrari F60 F104 Formula One Kit or Tamiya 1/10 Vodafone McLaren Mercedes MP4-24 F-104 Kit for around $180 and out fit it with my TC parts and I am ready to go?
Do I need to replace the stock tires if so with what? What do they use at carpet nationals or IIC?

Depends on where you race. At my local track we run 180s, 190s and 200s together also the FGX. Pit shimizu tires are popular. Gtb will work, but its a tight fit, not a lot of room.

What is your budget?
If you go the mail order route you will probably spend more than you need to.
If you PM me I will work up some options for a competitive racecar at a competitive price
you can also check out my website at
http://f1paintlab.com/zencart/
I am still fine tuning the site, so not everything is listed, and I am adding new stuff all the time. But I can help you out if you want

Probably medium front and soft rears to start. It's easier to dial steering out than it is to cure large amounts of oversteer without rear additive.

What I'd done with WGT tyres before at a pressed for time club meeting is additive them a couple of times, then run without for the rest of the night. As the track cleans up and the additive gets into it then you need less on the tyres.

Have fun and shout if you need any more help or advice
