How to How to "Heel & Toe" Downshift This example illustrates a single heel-toe downshift from 3rd gear to 2nd gear. Step #1 – Acceleration We typically start from full throttle acceleration down a straight towards a corner. Step #2 – Start Braking Lift the right foot from the accelerator pedal, carefully place the ball of the foot on the right side of the brake pedal, and slow the car with appropriate braking. It may help to keep the heel of the right foot slightly off of the floor. Step #3 – Begin the Downshift Nearing the end of the braking zone, the left foot moves to and depresses the clutch pedal. The hand begins the downshift. Step #4 – The “Blip” The right foot rotates on the ball of the foot until a portion of the shoe overlaps the accelerator pedal. As the shift lever passes through neutral, the right heel gives a quick push of the accelerator pedal and then is just as quickly released. This “blip” increases the engine speed. The ball of the right foot continues its constant, smooth pressure on the brake pedal throughout the maneuver, without disruption from the “blip”. Step #5 – Complete the Downshift The shift lever is in the new gear and the left foot smoothly releases the clutch, as the right foot continues easing off the brake. Step #6 – Complete Braking The down shift is complete. The right foot can now rotate off the accelerator pedal. The right foot completes the braking with a smooth release of the brake pedal. Step #7 – Accelerate The right foot moves over to the gas pedal to assume the normal position; at first only to maintain the pressure needed to sustain the vehicle speed though the initial part of the corner (“maintenance throttle”), then pressure is gradually applied as the steering wheel is straightened to accelerate out of the turn. Done correctly the engine speed generated by the throttle blip is sufficient so that as the clutch is released the engine speed matches the car’s wheel speed. There should be no undesired change in brake pressure as the throttle is “blipped”. There should be no perceptible lurch of the car when the clutch is released. bv rev 12/4/2015 Heel & Toe Shifting The Heel and Toe technique is the ability to use three pedals (clutch, brake, and accelerator) with two feet. It really should be called “Ball of the Foot/Side of the Foot”. Let’s see why: 1. The objective of “heel and toe” is to be able to brake for a turn, select the proper gear for that turn, complete the shift while continuing consistent braking, and then use the throttle to adjust weight shift throughout the turn for maximum control of your car. 2. In a situation that requires braking and a gear change, remove your foot from the accelerator and step on the brake pedal with the ball of your right foot. The ball of your foot gives you the most “feel” and allows you to control the amount of pressure you are applying to the brakes. 3. The brakes should be applied smoothly while increasing the pressure as is needed. Do not jam on the brakes suddenly as this may cause one or more of the wheels to lock up causing a loss of car control. 4. When the speed of your car has been reduced sufficiently to select the next lower gear, depress the clutch with your left foot while continuing to apply pressure on the brake pedal with the ball of your right foot. 5. At the moment the clutch disengages, the engine speed will drop to an idle. If you were to change gears now and let the clutch out, the engine may be at 1000 RPM’s while the transmission is turning at 4,000 RPM’s. When the clutch engages something has to give; either the clutch will slip and cause your car to jerk or the rear wheels will slip and cause your car to jerk. In either case, you will upset the balance of your car and you could lose control. 6. Therefore, just a split second after depressing the clutch and before the engine speed drops too much, roll your right foot over onto the accelerator pedal using the right side of your foot, and while maintaining the same pressure on the brake pedal, quickly and briefly press (or “blip”) the throttle. 7. The “blip” will get the engine RPM’s up so that as you change gears and let the clutch out, the engine and transmission will be going the same speed and the gear change will be smooth.

  • Wheel Alignment Simplified
    The WHAT and WHY of Toe Caster - Camber Kingpin Inclination - Thrust Angle Steering Angle – Wheel setback WHEEL ALIGNMENT SIMPLIFIED Wheel alignment is often considered complicated and hard to understand In the days of the rigid chassis construction with solid axles, when tyres were poor and road speeds were low, wheel alignment was simply a matter of ensuring that the wheels rolled along the road in parallel paths. This was easily accomplished by means of using a toe gauge or simple tape measure. The steering wheel could then also simply be repositioned on the splines of the steering shaft. Camber and Caster was easily adjustable by means of shims. Today wheel alignment is of course more sophisticated as there are several angles to consider when doing wheel alignment on the modern vehicle with Independent suspension systems, good performing tyres and high road speeds. Below are the most common angles and their terminology and for the correction of wheel alignment and the diagnoses thereof, the understanding of the principals of these angles will become necessary. Doing the actual corrections of wheel alignment is a fairly simple task and in many instances it is easily accomplished by some mechanical adjustments. However Wheel Alignment diagnosis is not so straightforward and one will need to understand the interaction between the wheel alignment angles as well as the influence the various angles have on each other. In addition there are also external factors one will need to consider. Wheel Alignment Specifications are normally given in angular values of degrees and minutes A circle consists of 360 segments called DEGREES, symbolized by the indicator ° Each DEGREE again has 60 segments called MINUTES symbolized by the indicator ‘.

Holowka* and Daniel E. Lieberman* ABSTRACT presumably owing to their lack of arches and mobile midfoot joints Adaptive explanations for modern human foot anatomy have long for enhanced prehensility in arboreal locomotion (see Glossary; fascinated evolutionary biologists because of the dramatic differences Fig. 1B) (DeSilva, 2010; Elftman and Manter, 1935a). Other studies between our feet and those of our closest living relatives, the great have documented how great apes use their long toes, opposable apes. Morphological features, including hallucal opposability, toe halluces and mobile ankles for grasping arboreal supports (DeSilva, length and the longitudinal arch, have traditionally been used to 2009; Holowka et al., 2017a; Morton, 1924). These observations dichotomize human and great ape feet as being adapted for bipedal underlie what has become a consensus model of human foot walking and arboreal locomotion, respectively. However, recent evolution: that selection for bipedal walking came at the expense of biomechanical models of human foot function and experimental arboreal locomotor capabilities, resulting in a dichotomy between investigations of great ape locomotion have undermined this simple human and great ape foot anatomy and function. According to this dichotomy. Here, we review this research, focusing on the way of thinking, anatomical features of the foot characteristic of biomechanics of foot strike, push-off and elastic energy storage in great apes are assumed to represent adaptations for arboreal the foot, and show that humans and great apes share some behavior, and those unique to humans are assumed to be related underappreciated, surprising similarities in foot function, such as to bipedal walking.

  • Most Americans Suffer from Foot Pain
    NewsWorthy Analysis Page 1 of 8 NewsWorthy Analysis Foot Ailments Survey January 2009 Down At Their Heels Heel Pain Tops America’s List Of Persistent Foot Ailments The American Podiatric Medical Association recently conducted a national study which investigated how frequently Americans suffer from foot ailments, specifically heel pain. There were 1,082 survey respondents, a nationally representative sample of the U.S. population. Of these respondents, 818 had experienced at least one foot ailment within the last year, with 429 Americans reporting heel pain. This study was conducted at a 95% confidence interval with 3% margin of error. From standing for several hours each day to wearing ill-fitting shoes, exertion and discomfort take a serious toll on American feet. For many, the pain is serious enough to inhibit daily activities. Yet when problems arise, getting proper foot care is not the first thing on most American minds. A new survey by the American Podiatric Medical Association shows that this combination of bad habits and a reliance on quick fixes may be contributing to the nation’s foot woes. With heel pain as the most common complaint among those who suffer foot ailments, few people who have experienced it have taken the time to get their condition diagnosed. Furthermore, heel pain sufferers tend to consult sources other than podiatrists, instead of seeking appropriate professional care. 1) FOOTSORE NATION With a range of widespread and sometimes self-inflicted conditions, Americans’ foot problems can get in the way of their daily lives – heel pain in particular can exact such a toll.

  • Set Toe Properly
    SET TOE PROPERLY You will get better more consistent results adjusting your toe in settings if you go the extra mile to eliminate variables. You must first decide which technique that you plan to use to take the measurements. Each technique offers different benefits and drawbacks. The methods discussed here will be the Toe Plate method, Toe Bar Method and Tire Scribe Method. If you understand each toe setting technique you will be assured of repeatable results. Before you begin taking measurements you must insure that the car is race ready. Ride heights set, weight percentages correct, driver weight accounted for, bump steer set, camber and caster set, Ackerman set, air pressure set, stagger correct....you get the idea. You should also inspect the steering components and replace any that are worn or bent. Center up the steering before you begin. Center the drag link or rack so that the inner control pivots and inner tie rods are centered to each other. Tie rod lengths should be adjusted to match you lower control points if possible. String the right side of the car to line up the right front to the right rear. By lining up the right side and starting with the right front in line with the right rear you will eliminate any Ackerman effect that is in the car. If the wheels are turned away from straight when you take your toe measurement the Ackerman effect can add toe out that will not be present when the wheels are straight ahead. Take the time to string the right side and you will get more precise results.

  • Chassis Tuning 101 Matt Murphy’S Dirt Oval Chassis Tuning Guide
    Chassis Tuning 101 Matt Murphy’s Dirt Oval Chassis Tuning Guide PREFACE Over the last 17 years of my life, I have raced Dirt Oval all over the United States, on foam tires and rubber, hard packed and loose dirt. I have learned a lot about chassis setup on many different track surfaces with many different types of cars. Much of what I have learned is from trial and error, and quite a bit I have learned from doing plain old research on race car chassis dynamics. My goal now is to take what I have learned, and share it with you, but I want to do so in the simplest, easiest to understand manner that I possibly can. I certainly do not know everything, and I am not always right, however I can say that it is rare that I work on a particular chassis setup, and do not find improvement with each adjustment. My theories are just that, and are intended only to help you better enjoy your RC race cars, no matter which make and model you choose. Some things I pay much more attention to than others when it comes to chassis setup, but please understand there is no right or wrong, there is simply what works best for YOU!
