I've been talked in to trying the SD again, so I picked up a Rayspeed Ultimate SD

6.9-7.1 thats what i usually run on a p2k2 pro and it works really well...but on a monster i started at 6.59 all the way up to 8.24 and nuthing worked...i test 6.33 too but still the motor is running really really hot...i guess i'm gonna try to go 8.67 or maybe on the 9ish....i talked to someone running a tc3 with the a monster stock and he geared his car 9.47...maybe i'm wrong about thinking its a large track...i just know its the biggest track around here...it's fairly technical...the parking lot lines up around 8 to 10 cars side by side by 4 cars bumper to bumper....i dunno how long but think toyota tacoma....thnx for the input guys

Didn't you run that like once and get rid of it the first time around?

Yep, that SSG car sucked in my mind, but I did promise that I'd try the Rayspeed SD when it was released...

if you gear your p2k2 that low, i guess you have to gear the monster even lower...

check out the other racers gearing, and that should your basis, i found that 6.8 to 7.2 is about right for the monster stock.

Default Front hinge pins

Hi Kevin K,
I've seen in your recently posted "foam on carpet" setup, you put 2R pivot support in front: so you reached the condition of parallel front arm pins.
I have done the same by modifying the pivot blocks wider and the pivot support narrower (dremel and some epoxy resin helped me!). I tested the car with foam on asphalt, and my feeling is that it is more stable and planted than before and the average time in race condition is faster.
I already discussed on this with Todd Hodge. Any thoughts from you? Why Losi made pins unparallel on the XXX-S? And what about a kit from Losi for "parallel pins?"
Thanks,
EddiRossi.

Ok when I drove the car with the 2r block in the front it gave the car more steering and it just felt better on corner exit. Now what this mod does is two things one is it narrows the front track a bunch and changes the drive shaft angle. Your wheel base is also slightly changed as well. I was told once by a very well respected person in RC that the drive shaft angle controls on power traction at that end of the car. Example....if the front CVDs are angled towards the back of the car they will have less on power traction and if they are angled towards the front they will have more on power or forward traction. I dont know I cant speak for why Losi did that but I would think it had something to do with making the car easy to drive for everybody or something like that.

cool... i will definitely try out this modification. i have been lacking steering on some of the exits of our track, hope this solves it.

so, let me get this straight, i just pop in the 2R in front? and check the front toe?
