thanks for the gearing help guys, i will try a 13 and a 14 and check temps. 150-160 degrees. the only thing is the mains are 2 minutes longer than the heat races so hope i can get a second faster.

sorry about dropping a F bomb before i forgot this is a associated forum and we have a little more class. just i was going to my LHS and didnt want to buy a handful of pinions i didnt need at 10$ a wack.

good luck to everyone at there races stay smooth and out of trouble! because track marshalls are slow these days.

The chart indicates a number of things, nominal 2s voltage, peaked 2s voltage, Kv, RPM, Rollout, spur and pinion size and MPH.

Basically the chart will only work if you use the 62t spur gear. I shoot for a MPH around 35 or so......

The chart shows the effect pinion size has on a range of motors. While using 2s and a 62t spur. Pinion from 10t to 20t.

Pay no mind to the color effect, it denotes the target range of around 30mph.

Same experience here, gained traction with the blue rears. The theory behind all this is because the AE truck is unique in that it carries more weight in the rear, which means it needs a heavier spring in relation to the front than normal for a balanced setup. (First thing I learned before taking a motorcycle to the track was to make sure it was sprung for my weight!)

Try it, you will be surprised. Just make sure to go up in oil weight 2.5-5. What I found is that the truck was way more planted and settled in long sweeping corners, and I could get on the throttle quicker on exit. The rear stopped its dumping over mid corner, where I'd have to ease off the throttle to bring it back, then get on it again. Now the rear just settles into the corner and stays there, and I can stay on the power through the entire corner.

Notice the scte's drive out of that 90 into the double a couple turns before the straight? Maybe Mayfield was just taking a more conservative line (single/single) through that section and didn't want to roll the dice there, but that's what I see as the main advantage of the scte at this track... the center gear diff applying power where the slipper slips.

Mayfield had a lot more squirt on the straights and did a great job at protecting his position while staying clean and consistent FTW.

(hope to make it out this week and get on that track before they change it)

Honestly, He did an excellent job defending A1 because Ty was much faster than him. You could see 1 little bobble from Ty and he catches back up in a quarter lap. Ty was trying SO hard to pass him and couldn't do it. If he had he would have bolted away and wouldn't have been touched. Maifield's defense was the only thing that kept him 1st in that race. imho

A2 was a different story.

You sure ?

I did notice Mayfield's superior Reedy power & on the 2nd heat the center diff cars spinning their wheels .....

Yeah, the lighter chassis and that motor had the beans on the straight.

Didn't get to see much of the losi's once Ty bobbled at the beginning Mayfield checked out... except for that pass on cavaleri, not much wheel spin there.

Great race and I'm bummed I didn't make it out there with it being only 30 min from home
