With an Orion 3.5 I really liked gearing around 9.3-9.4 for a fairly small track (80 ft straight) the S400 has no problem going lower than that though. I'm running a 106/24 now with an Orion 3.0 turn and it feels really good on the same track.

randy, 3.5r running 9.3-9.4 ratio ? i thought brushless ratio will be higher than brushed motor ?can s400 fit 21t or 22t pinion with 106t spur??

thanks

I've never tried to go that low, but I don't think it would be a problem. What motors are you running?

Also, if you are running 6 cell packs you will have to gear lower than with 5 cell packs..

i nt yet buy motor but i already bought lrp sphere competition 2007 esc....

i heard d fastest motor around is Team orion ??? i'm planning to use either 3.5r or 4.0r...will be running 6 cell i guess since d weight limit is 1500 with transponder...

The Orion motors have awesome power with the LRP Sphere. We run mostly 3.5 turn motors, but use 5 cells. With 6 cells you would be fine with a 4.5 most likely.

randy, is it if i use 6 cell on 3.5r , d power will be too much or d motor cannot handle it ??

if i use 6 cell with 4.5r , can i still catchup with 3.5r with 5 cell ???

thanks

6 cells with a 3.5 is a lot of power, the motor can handle it, but most people can't... It will want to spin the tires exiting every corner basically.

6 cells with a 4.5 will be very close in speed to a 5 cell 3.5, maybe slightly faster.

Randy and Butter,

Since you guys have both run the rear gear diff in your cars, what range of oil should I buy to cover the typical range of traction. I will be racing outdoor rubber mod and 10.5 on low to med-high bite track. Expected asfault temps are about 60* to 90*.

Thanks,
Steve

I know I am not either RC or Butter, but 3k, 5k, 7k .... should be good for most situations

Thanks Tim,

I appreciate the quick answer, I should have included you too, I know you race with Butter and have been running really strong with your Serpent in the Florida State Series. Have you guys had a race lately?


Much Thanks,
Steve
