Calling all guys (and girls) who race their Rustlers.
This is a post I’ve been wanting to do be able to do for some time.
For the first time ever, last week my (just turned) 13 year son achieved the unthinkable with his race modded Rustler VXL and won the Modified Truck final (and one qualifier) at our local track against a bunch of AE T4s in the hands of more experienced drivers. Adults race with Juniors at our track.
While his race time was still about 10% off the fastest stadium truck times ever recorded at the track (by a T4), it was nonetheless a victory on the night both for him and for Traxxas. So much was the surprise that the club committee decided to award him an on the spot prize for the achievement (new Lipo). The stunned look on everyone's faces was priceless.
In an attempt to share some of what we’ve learned over the past 10 months since we started racing our three Rustlers and inspire others to head to their local tracks, I’ve posted full details of his car and set-up at that race meeting and the prevailing track conditions.
His car (like mine) is still very much evolving and I’m hoping that some other Rustler racers out there can give some advice as to what they would change to make the greatest improvement to the car’s performance potential.
Improvements already in the pipeline are:
1. Castle MMP ESC (to allow a little drag brake and punch control)
2. FLM sealed gear differential (with 50k or 100k diff oil)
3. TRX SRT front shock tower
4. 2oz of additional weight at the front
I think it would also be great if other successful Rustler racers would post their own successful set-ups to share with others – copy the headings below as a template if it helps.
