thanks Sydewynder,

I agree on the tensioner pulley washer issue...I dropped the washer as well....doesn't really need it.

My issue was less one of rubbing (like proudwinner, I have run my 118 spur anyway, even with the runout issue) and more one of quality control at Losi...3 spurs purchased - 3 spurs with problems. Maybe they need to retool their molds for their spur gears

I've been running the MF gear adapter with kawada spurs, and they work fine. I did notice this week that my belt got a bit slack at the end of the day...not sure if it was the pulley, or a loose screw on the tensioner...

Cheers,

Rich

I have not had any problems with my spurs. I did have a problem with the MF adaptor something rubbing. I do think losi is coming out with new spur gears. I saw bk testing some also some new belts

They have been working on a "yellow" belt, which i am told will be aimed more twards stock racers.

has anyone else had this problem with the tensioner??

I believe that the white plastic piece gets a little loose on the bearing which causes the white piece to shift around during a race. This happened to me over the weekend and caused my belt to eat itself getting caught between the tensioner and the spur. I check the screws on both the tensioner ....one that holds the bearing on....and the screw that holds the tensioner in place and they were both tight.

Just curious if anyone else has had this happen and if so what did you do to fix it?

Default Shock towers

A quick update, rear shock tower design is coming along quite nicely- it will make the back of the car very adjustable Hoping to have some in racers hands within 3 weeks. If they prove themselves on the track, we'll have our first batch done before OktoberFAST(the first race in the USTC series, the first weekend of october)

I have a question- Do you have something that you'd really like in the front tower, please let me know. Feel free to email me at, [email protected]

Thanks guys!
Ben, Team PRP

ChadK,
What roll center setting are you running with the setup you posted on the previous page?

racerdave-That was high roll center both front and rear. On asphalt I have always liked high roll center.

yeah, some different camber holes will help a lot of us out. And one question, how much will you guys be selling the rear and front shock towers?

Chad or anyone,
How do you know when to change to a low roll center?
All else being equal, how do the two settings differ, how do they feel? I know that this probably covered a few hundreded pages back, but I am lazy!

Thank you.

shrekair you have a pm
racerdave- for roll center I found running low in the rear only makes your laps a little fast. I have run this for a while and never change it. If you want to change it raising the front in relation to the rear will gove more mid coner steering and exit and vise versa when lowering the front.

blanket statement but isint always true as any statement.

HRC (high roll center) more turn in

LRC (low roll center) more steering from apex off.

low roll center softens the suspension, so to achieve the same handeling, stiffen your springs one step f/r.
if u break it down to "how does just front HRC affect the car vs. LRC?" it's still the same. high roll center in the front only will still be more turn in, less turn off. and same with the rear. higher is more turn in and less turn off. i was thinking about this myself and thats exactly how is worked in my car.
