Why would anyone come onto the Type R thread and post something silly like that. If anything shaft drive cars are out of date. No respected manufacturer has used that design in a top level racing chassis for a long time.

It will depend a lot on traction available. At my local tracks i run Front - Low +1.3mm, and Rear - Low settings. Its also largely dependant on the spring rates that you use too... just to confuse things a little.

Needing help. Rebuilding one losi 10mm shock for my pan car as that it what is uses. The question is, anyone using the optional double o-ring option and if so does it make any difference vs single o-ring?

I use the twin oring setup. The shock isn't quite as free, but it seems to seal better over a given amount of time.

As a matter of fact they are you must be a mind reader.

They are currently back in stock and I'm filling back orders (some went out today already).



My shipping time to the UK is via USPS Global Priority, which should take about 6 to 10 days.

Yes my shocks lose rebound so I am looking to do this soon. As far as a bit more friction is concerned I all ready run 57 pistons to increase dampening/pack as the losi will ALWAYS have rapid direction change so there is little need to consider that in you dampening setup. A little heavier will promote more mid corner performance so double o-rings will not hamper performance.

As for rubber rollcenters I run full low all round. This has allowed me to match the lap speed of our countries fastest driver (B final at last worlds). For me rubber is simple.. full low and tune from there as you can reduce steering easy if you have too much grip but adding more if you need it is time consuming when you need to play with rollcenters for more grip. I have tried diffs low and high and feel no difference but high has the advantage of keeping the belts a pulleys away from the crap on the track so I now run high all round.

I've seen both high and low roll centers used at the same track effectively, leading me to believe it's about driving style and rest of car setup, but I'd love to understand what the difference in roll centers does to the Type-R vs the traditional TC.

This is an awesome explanation of Roll center: http://www.rc-truckncar-tuning.com/roll-center.html

a short excerpt:

Roll center is the point on your chassis, both front and rear, the point your rc vehicle pivots on in a corner. In most cases the roll center will be different on the front and rear, since we hardly ever have the front and rear suspensions setup the same. In a corner centrifugal force causes your rc car or truck to lean into the corner. The point at which your front suspension pivots on is your front roll point and the same holds true for the rear suspension.

So my question is how does this "lean" affect the Type-R specifically, does low roll center promote lean, or does high roll center promote lean?

I've been talking about roll in the corners quite a bit with Scooby and how to get the car to roll without dumping over in sweepers, yet maintain the snappy-ness in the chicanes.

Its the distance between the center of gravity and the roll center. The larger the distance the more leverage = more lean. Lower roll center is going to be a greater distance from the CG. Good example would be off road cars. High CG, low RC. Motorcycles are the opposite. Low CG and very high RC, thats why they lean into a corner.

I use this software Roll Centre and Camber Gain Calculator
For me having roll centers within a mm front to rear seams to work out the best for me.
