jeremy I dont run the 13.5, really only ran one 2 rounds thats why I was wondering if any one had ran them side by side.
At our track we would exsperiment both ways side by side. But for some reason we dont do that any more we just race. So I was wondering if any one had. But A 40mm roll out?
That has got to be one big track I would think. I know guys are talking the same at our track but I;ve been running 4300 and dont need that much gear. It sounds to me it would be better to just bump up to a 4300?
Dont let this post be taken as a loud tone. Its not. The Most I can do with a 4300 is 32mm rollout. Medium track carpet foam.

I gear mine at a 4.7-4.8 FDR as do most of the people at our track. (Indoor carpet)

I heard rumors that Charlie Novak was down near 3.9 at the novak!

Slamman: Whats your battery doing? Is it fadeing? And is the lap times VS battery saying Gear up? I mean are you starting at a 10.0 and ending at a 10.0. I can remember pics of your track from a previuos thread.

Its not that big... wish I could give you some demensions but I'd just be guessing and it probably wouldn't be close.

Its not a tiny techniclal track... I'd consider it a medium size track.

XMS is right... at Trackside we run 4.6 - 4.8 FDR with rubber tires. I also ran 4.8 FDR tonight at a much smaller track with no problems... motor temped at 145 (with the sintered rotor)

I would say that I am running on a med size track also. You can see a pic of the track here www.glennshobbycorner.com just look down the right side and click on tracks.(ya we need new carpet). As far as running them side by side no we haven't but I can say that lap times are consistantly better with more gear.

Nice track. See now I would guess 30mm or 31mm on a track like that.
I would gear the motor till it wound up about three quarters of the way down the longest straight. At 40mm we're talking approxamitly 8 teeth taller than a brushed stock motor. Dang thats a lot.

That track looks similar to ours but with room for a couple more turns in the infield and a longer back straight. Just try the tall roll out at 38-40 mm.

I just started running a 13.5 and am at around 36.5 for rollout right now and the power is good. Medium carpet track with foams in an RDX.....You definately need to throw gear at this motor. On the same note, I am rolling out my 4300 at 28.5 and it hangs with Komodo's all day long with the stock bonded rotor. Also using the 2007 versions of the Sphere Comp...Make sure you set the battery mode to Comp NIMH if you are not running Lipo's....

Yup, I was running a 4.6 FDR in mine at the Novak race, & it was actually Bob Novak that told me he was running a 3.9....that being said though, it'd gonna depend greatly on how your local track's set up, at mine(in Oklahoma), we're now allowing the 13.5 to be used in stock(after much debate, but only allowing it with the original rotor, no sintered ones), & here I've found that motor temps can be MUCH more a problem(shorter, sometimes tighter track here, not as flowing as Trackside). I started practice yesterday with a 5.6 FDR in Stock Rubber & it thermaled on me(& that's with the GTB, not the Sphere), but going further down to a 5.8 seemed to be enough to prevent the shutdown(but it's still pushing it a little, gets pretty warm after a race). And fullsyzz mentioned hius motor reaching 177 degrees, that's VERY bad with the original rotor, Bob & Charlie told me at the Novak race that above 170 degrees the original rotor's magnets can take SERIOUS damage(to their magnetic field), which is why the GTB will try to shut the motor down before that(but counting on a thermal shutdown to prevent damage is not smart, better to prevent those temps in the first place).....

Heres a pic of the track, well 75% of it anyway, unfortunately you cant see the last 20ft of the straight and a big sweeper. Haven't got to test yet anymore, but I will get this licked one way or the other. At least Novak will replace it for $40, so worst case I spend $40 a couple times learning to gear

Ahhh, yeah, looks close in size to my local track, maybe you should try gearing a bit more conservatively & see if that helps....
