wow... what a weekend at Motorama. Still trying to recover from the sleep deprivation.
I went with the intentions of running 2wd Mod but added 17.5 as well. Figured enough down time to run 1 car, 2 classes, like the old days with brushed motors.
YEAH.... never again. I spent all day Friday swapping spur gears, motors and changing ESC profiles that I didn't get much time to do anything else except prep tires. I decided to focus on 17.5 and just use mod for practice for 17.5 class. Made it easier. Plus I figured since I had never run 17.5 or any other spec class, it would be something different and I would learn some new stuff.
I grabbed an old 17.5 loaner from a buddy and strapped it in. Ran 36/72 for gearing. This was Blinky so no boost. Car had tons of power everywhere. It was great. Setup wise, I ran the Worlds setup with Losi orange / yellow combo. Used green barcodes all the way around (V2 rear). LRP SXX v2 with 1/0/0/5 settings (3.0 software). Only thing I changed in my car all weekend was I put 3.0 deg inboard toe back on compared to 2.5.
As far as my performance... I was very satisfied for my first real big race on dirt in close to 10 years. TQ was 13 5:12 ish and I was 12 5:16 so just about 1 lap exactly off. Needed to just hit 13 to make the A so wasn't that far off there either.
Hopefully this helps someone. I noticed an influx of new people asking the same questions we answer 10 times a day. Search for it (really) and if you can't find it, ask us. If you are afraid to get flamed, PM us

. I LOVE helping people out and seeing all these new guys means hopefully we just added a new RC racer to the mix.
