some people say it is a little faster to put a smaller spur whit the same ration I was wondering if it was true !

Mainracer....your going to be moving the position of the motor around so the weight balance will be slightly altered. I think that when you go to a smaller spur with the same overall ratio the car has a higher top speed.....but I could be wrong thats just how I feel about it.

bigger spur will give more punch but not as much on the top end while the smaller spur may not have as much punch out of the corners but it will be very good on the top.

LOgically the same ratio should mean the same speed right? I'm confused

sounds like overheating... maybe a higher shore rating will be the key... or harder set-up all around...

about the ratio question... there was a really long debate about a month ago in the TC3 forum about the question MAINRACER asked, and there was a long discussion on what the effect would be... personally, i have to agree with STLNST... the smaller spur will make the motor spool up faster, therby giving the impression of punch, with a higher spur as against a smaller one... however this i also believe this to be noticable in the bigger tracks... and with mod motors...

I recently purchased a XXX-S Sport RTR and it should be arriving to my house in a week or so. The car is going to get heavy use as a pavement basher and I may race it in a couple months if I have the time to travel to some races (I do not have a LHS). I realize the Losi RTRs are not on the same level as the kits, but the RTR pacakge was so cheap I could not pass it up.

I have read quite a few of the posts in this thread and most are centered around racing and not bashing. Since I will not be racing right away, I am looking for a good setup for unprepared pavement surfaces. In particular, I am looking for a good tire that will last a while and have decent grip wherever I go.

Next up, what is going to break on the car so I can get some replacements before it happens? Does anything need to be hopped up on the RTR right out of the box for bashing duty? Any other advise on the XXX-S would be great as well. Even thought I will just be driving around for fun for a while, I still want the car to handle well and not go through parts like crazy

Are you running in wide open spaces, or will there be a possiblitity of hitting stuff.... mainly solid stuff... If you don't hit anything and the tires nevr leave the ground then you shouldn't brake anything....

For tires I would chck out HPI X-patterns they seem to be the most durale and work under many conditions.... They have just enough tread to help in dusty conditions, but not enough to reduce preformance on clean asphalt...

I should be running on open spaces with mostly grass edges but I assume a few mail box posts or curbs will come out and run in the car *cough*

Can the XXX-S easily be converted to a rally setup for pavement and packed dirt use or is there not enough suspension travel?

Thanks for the reccomendations on the HPI X tires, they look pretty good for my purposes.

Does anyone know where I can get those little 2-56 screws for the bottom chassis cover without having to buy the cover?? I didnt find a part number for those in the manual. Thanks!
