go faSt by going Slow.SeRiouSly. It is counter to your instincts, but in many pursuits you really

can reach your goal by occasionally slowing down. It is

critical to regularly take time away from the ‘doing’ in order

to examine your goals, strategies and plans and to do what’s

called preventive maintenance.

Here is the scenario that professionals keep in mind. Picture

this. A team of people (maybe you and your friends) are

clearing an area of young trees to setup a racetrack or skate

park. It seems that there isn’t a minute to spare so the cutting

is constant! Cut. Saw. Do! In reality however, you eventually

are cutting with a dull saw. By sitting back and taking care

of your resources, by sharpening that saw, the work will go

faster. Professionals call this “Sharpening Your Saw”.

In racing, what you think is fast may not be fast. You literally

may go faster by going slower. If accelerating and braking

constantly, tires may actually be skidding which is slower

than driving and you are definitely wasting energy so you

have to pit more often. Consistency is as important as speed

in most Ten80 Student Racing Challenge events. This guide

will help you cultivate both without spending hours repairing

a car you couldn’t control.

coach’s notes

This “Driver’s” certification is designed to teach students how to control the 1:10 Scale RC Car as well as determine their strengths. Some take naturally to driving these cars while others tend to have a very difficult time controlling them. These challenges are used to give students a chance to practice driving and then actually help them make the decision if they are a good driver or not. You need to encourage your students to really work as a team and begin identifying their particular strengths. Some students are great timers, some are great record keepers, others can drive and others are great problem solvers. Having a diversity of strengths on a team keeps that team strong and each position is just as important as the other.

The RC Relay race is a fun way to introduce driving. Run the activity to show everyone how the car works. Afterwards, point out that the car is NEVER again to be driven without collecting data on some aspect of its performance! From that point forward, students will write down any thoughts or observations in their journal when working with the car. This should be an ongoing process and they should have their log book/journal with them at all times. It is important that all relevant information be recorded because they may need to refer back to data at a later time. Also, the data collected and recorded will support the students that consider themselves good drivers.

You have to be sure to point out how all jobs on a team are important and that everyone have a chance to do every job. Each student will have the opportunity to drive and each student should be a timer as well as record data. They need to be able to try each and find which ones they like and which ones they are good at doing. Stress the idea of team work throughout this series of challenges.

Some students will not be able to complete the challenge in the time you give them. Those particular students will probably not be the drivers once you select teams. Go through all of the challenges before you decide who should drive. You should also stress that everyone should use data from these challenges to support any claims about being a ‘good driver’. Just saying you are a good driver is not enough.

Administer the certification as follows:

1. Go over activities to make sure everyone understands them.

2. Agree to the ‘rules of engagement’. For example, does everyone need to be certified in everything, or just things they will be responsible for?

3. Observe teams and provide support and feedback.

4. After each challenge activity is completed, review logbooks and provide feedback if necessary. Sign off if it is completed successfully so they can proceed to the next activity.

5. When all Certification activities are completed successfully, sign off on the full Certification Table for each individual or team. Download, print, sign and present the certificate.

Through “Driver Certifications”, you and your teammates will effectively receive drivers’ licenses. You will start by showing your personal control of the car at slow speeds, then at high speeds and finally at turns. Your natural urge is going to be to drive fast and drive NOW! Our Ten80 team of engineer-educators has designed a procedure to help you cultivate patience, care and systematic thinking. These skills are as important as aggressive competitiveness for an professional diver, professional athlete, politician and Student Racing Challenge team. To avoid injury to your kit and help cultivate both the art and science of driving, you should follow this procedure: Run a driving challenge until you meet one of the following:

1. You successfully complete the challenge

2. Your track time is over (varies from challenge to challenge)

3. You ‘hit a wall’ and violate one of the challenge rules.

If you successfully meet the driving challenge, then your teacher will review the activity data, sign off on it and you can continue to the next one.

If your track time is up or you hit a wall and violate one of the challenge rules, then pick up again where you left off next when it is your turn again. Meanwhile, relinquish your driving to one of your team mates and become a timer.

If you fail to complete a challenge in this unit, it is ok because this Unit is also designed to help you form the best team possible. Throughout this process you will find out if you are better at driving, recording data, timing, solving problems, etc. You need to make sure that throughout this process, you self-evaluate and think about what you are good at doing. This only works if you are truly honest with yourself. Just because you want to be a driver, doesn’t mean that you will be a good driver. A team needs members that are good at different tasks. A team is not a great team, if it only has great drivers. That team will probably never win a race, because only having good drivers won’t help if you have to figure out an answer, or solve a problem. At the end of this unit, you will be asked to evaluate yourself and your team members and give feedback to your teacher. Your teacher will then take into account your feedback when determining the final team rosters. Keep in mind that in order to be considered a good driver, you need to back up your claim by showing your times using the data you have collected.

organize

1. Form a team of 4 - 10 people (depends on your numbers).

2. Teams line up at one end of the track and listen to instructions on how to run the car and relay race (see below).

Practice

3. Turn on the car by following the “Car Startup” Procedure. Practice driving.

Relay time

4. Split your team into two with half lining up on one end of the track and half on the other.

5. The first person to drive sets the car at the start line.

6. When the leader says ‘GO!”, begin the relay. To race:

• Drive the car down the track, walking just behind it.

• When you reach the other end, hand the controller to your team mate and using your hands, turn the car around to place it at the new start line. Keep track of how many laps you complete. A lap is one length.

• Repeat until time is up. The team with the most complete laps wins.

Pre-Qualifier: Rc Relay

car startup Procedure1. Charge and install

7.2V car battery & AA controller batteries.

2. Check the steering & throttle trim knobs. Your car can run away (forward or backwards) if the throttle trim is set too extreme.

3. Plug the 7.2V car battery into the ESC.

4. Turn the remote controller ON. ALWAYS MAKE SURE THE CAR’S ‘BRAIN’ IS ON BEFORE TURnIng THE CAR On!

5. Turn ON the Electronic Speed Controller (ESC).

6. Listen for it to ‘sing’. If it doesn’t sing, re-bind the receiver and controller.

7. Test the connection between transmitter and receiver.

• Make sure nobody is touching the tires. Pull the throttle trigger backwards (toward the handle) to go forward.

• Push it forward (away from the handle) to go backwards. There is a delay before it moves.

• Turn the steering wheel to see which way the wheels turn. Change the Steering Direction button if it isn’t what you want.

Challenge Introduction

our strategy for some Student Racing Challenge events may require a slow and steady speed along the whole track. First you find the top speed around the tightest curve and you drive that speed the whole time. This would be a good one if the score rewards you for going farther than you are going fast --- it works because accelerating uses A LOT more energy than driving a constant speed. Your first challenge is to consistently drive at a very specific average speed.

Performance Target to Meet

Drive the drag strip 5 times in a row with a drive time that is between 14 and 15 seconds without slowing down along the track.

Track

50 - 75 ft. drag strip. Mark a start line then mark a finish line 75 feet away. Drive in a single line from start to finish.

driver challenge #1: turtle vs. hare

Challenge Violation

You complete the course in under 12 seconds OR drive outside of the track lanes more than once.

Strategy Suggestion

To begin with you’ll probably speed up and slow down a few times along the track. Figure out where to pull the throttle controller to give you a steady acceleration to hit the target time. Put in a ‘throttle block’ so you can hit that every time. See the image below.

Challenge Summary

• Target Performance: Hit target speed 5 times in a row without slowing down

• Track: Drag strip, 75 feet long (50 if not enough room)

• Target Drive Time: 15 seconds (10 seconds on a 50 foot track)

• Target Average Speed: 75 feet / 15 seconds = 5 feet per second (What is target speed on a 50 foot track?)

• Start Type: Standing

Transfer what you learned in Challenge #1 - prove you can control the Ten80 Student Racing Challenge car. Repeat with a slightly higher target speed.


Drive the drag strip 5 times in a row with a drive time that is between 9 and 10 seconds without slowing down along the track.

Drag Strip

Mark a start line then mark a finish line 75 feet away. Drive in a single line from start to finish.

Challenge Violation

You complete the course in less than 7 seconds OR you drive outside of the lanes more than once.

Strategy Suggestion

Again seek out the throttle position and insert a ‘throttle block’ so you can hit that every time.

Challenge Summary

• Target Performance: Hit target speed 5 times in a row without slowing down

• Track: Drag strip, 75 feet long

• Target Drive Time: 10 seconds

• Target Average Speed: 75 feet / 10 seconds = 7.5 feet per second

Now you can drive consistently. Begin this challenge driving consistently fast, and increase your speed until driving as fast as you can while staying consistent.


Drive as fast as possible, 5 times in a row with a spread of only 1 second. For example, you’ll meet target with times of 4.1, 4.4, 4.9, 3.9 and 4.3 seconds. The lowest and highest number are less than 1 sec. different.

Drag Strip

Mark a start line then mark a finish line 75 feet away. Drive in a single line from start to finish.

Challenge Violation

You drive outside of the track lanes more than once or 15 laps without hitting target performance.

Strategy Suggestion

Start slow and speed up as you feel more comfortable with the speed. If graphing your drive time for every lap, you should see a consistent improvement toward the best possible time.

Now add a turn. There are a lot of paths to drive a U-Turn and over time you’ll gather data to show you which is best for a surface type. Today, your challenge is just to pick a path then drive it smoothly and consistently.


1. Drive the U-Turn 5 times in a row with a spread of only 1 second. For example, you’ll meet target with times of 7.1, 7.4, 7.9, 6.9 and 7.3 seconds. The lowest and highest number are less than 1 second different.

2. Once complete, do it again but this time, turn in the other direction. If you turned to the left first, now turn to the right.

U-Turn Track

Mark a start-finish line and place a turn-around point (cone, chair) 50 feet away. Drive from the start-finish line, around the point and back.

driver challenge #4: u-turn, Right & left

Challenge Violation

You drive outside of the track more than twice or 25 laps without hitting target performance.

Strategy Suggestion

Start slow and speed up as you feel more comfortable with the speed. Choose a drive path that feels good, put tape down to mark that path and attempt to hit the marks on every run.

Challenge Summary

• Target Performance: Drive 5 times in a row with a spread of only 1 second; turning left then right.

• Track: U-Turn, 50 feet long

gRaPhS tell StoRieS.If you ask a room full of people who they think the ‘best’ diver

is, chances are you’ll end up with a list of people. So how do

you know? You investigate. This scenario is no different than

a typical scientific process in that you have a hypothesis (“She

is the best driver.”) and you need to test it. The only way to

answer it is through data and analysis. It is just a lot of fun to

gather this data.

The graph below shows an ideal learning curve in which the

driver starts slowly and consistently improves with each try.
