big bore or small bore that is the question
 

I have an FS2 i have raced it once on a small indoor track with jumps and smashed it to bits as i struggled to get the car set up the way i would like it to drive i presume this will take some time for me to work out all the settings. I would like to get a second set of shocks for outdoor tracks only,:drool: so are big bores worth the extra money.

No in my view. I struggled with my FS2 SP on big bores, got some standard bores and haven't looked back. Big bores have just sat in the spares box since Jan now.

Post what your current setup is etc

I have an fs2 sp and have also had a fair few breakages getting it setup, and still not there yet. IMO compared to my Durango I would say they are a little fragile! I run big bores as It is all I have. They tend to react a little slower than big bores, which for me is good, but some drivers seem to like small bores because they react quicker. I'd say stick with small bores until you are sure you are happy with the car.

Small bores all the way! The big bores might be ok in certain circumstances but the small bores are good everywhere!

Look at the top kyosho lads and see what they run....

Hi Mikey
I bought the car of you just before xmas, using a set up of petric from nick at and indoor smooth track. I cant get the car to steer right at the mo and jumps are a problem too as the nose just dives after take off. but it is early days and i have so many things to tinker with. will be coming to your track once i have got a grip on things.

I personally prefer the car on big bores (although you will need to change the pistons for the UK surfaces ... have a look at the thread to see what I recommend). The barest minimum is to drill the rear pistons to 5x1.4 and run with something like 25wt AE oil in the rear and 40wt AE oil front on stock 5x1.3 pistons.

I picked up a load of time changing from small bores to big bores as the car was just far more consistent. If you speak to Kev Lee he will say the opposite though. That said there are loads of differences between my setup and Kev's (I use 7deg castor block, he uses 10deg for just a start!!)

To my mind the big bores are better for the average driver as they make the car react a little slower and thus a little easier to catch. I would agree that the small bores might be worth a fraction in terms of ultimate pace but until your going round for 5mins without an error then that is not important.
That said get to a track as rough as the moon and a properly setup big bore car will be able to carry much more pace than a small bore equipped car!

As for swapping between small bore and big bore on the same car I'd say DON'T DO IT!!! The reason for that is that you will want different roll centers and almost all the other settings adjusted too between them. This is down to the different levels of roll control generated by the big bore Vs small bore shocks so you have to manage that with geometry.

A lot of the fastest guys haven't had the opportunity to do the necessary setup work to adapt the car to big bores ... it is extensive ... so go with what they know as they can not afford to not be performing as people are watching.

Pays you money makes your choice but personally I am converted to the big bores (after 50+ hours tinkering time it must be said!)

That sound like good advice thanks. i will get another set of small bores for outside tracks so i dont have to fiddle too much with oil and stuff . has anybody got a set they dont want.

I struggled a bit too at first, the FS2 got so much setup options you could get lost. But after some work and a lot of advises it is now setup the way I want and I love it (tried a lot of others 4wd).

Small bores for me, better cornering and small jumps, even if it lacked stability on the rough stuff and big jumps.

I was not far with my last BB setup so I will work around them this summer.

So, keep the SB for now and work the setup (try the last Kev Lee one), then once the car will work for you (it should, you could do anything with that car).

A bit of work but very rewarding on the long run.

Check your drag brake too...

If the cars not turning right check your servo end and centre points. Also make sure the steering arm isn't catching on the wishbone. People usually scallop a small piece out of the arm to do this where they rub.
Also make sure you have right hand steering parts on right side and left on lhs. Sounds silly but you never know.

I've smashed most of the front end getting used to big bores. Use Rogers piston setups and those will help. I shattered a piston in 4 places when I had the front too soft, that was a completely wrong setup!
I find the big bores really settle the car, response is slower, but you can then just concentrate on driving it consistently. I'm slowly improving my times by just being able to repeat my laps and not crash!!
