History, Info (and How To Set-up Tips) for the DESC210R:


  Introduced by Team Durango in 2012, the 2WD DESC210R Short Course Truck - # TD102009 - was designed so the motor could be positioned towards the rear, or closer to the middle of the chassis. Two gear drive options were also provided, with either one or two idle gears.

  The model was based on a molded composite chassis, with a ball differential, coil spring over oil filled dampers, universal joint drive-shafts, slipper clutch and ball bearings.

Buying a Used Durango DESC210R Truck (and What to look for)


   Buying a used Durango DESC210R Electric Truck, or any used RC Model, has a number of advantages. It is generally cheaper than new, ready built and may come with a variety of expensive hop-ups already installed. Cheap, pre-loved bargains are always becoming available. However, depending on the age of your purchase, it may need a little tender loving care before you can take it out on the back yard.

   The one thing you will always need is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Durango website, or purchased separately on eBay. With an instruction manual, any problems with your model Truck you may discover can easily be fixed.

Dampers
   When you receive your used Durango Truck, make a general visual inspection of the chassis, front and rear wishbones, suspension shock towers etc, for any broken parts that may need to be replaced. Then, take a screwdriver and box spanner and check each self tapping screw and nut for security, taking care not to over tighten.

   Next, for those Durango models with oil filled shock absorbers, remove them from the chassis and dismantle the coil springs. The damper shafts should push in and pull out with a smooth action. If you feel a jolt as you change direction, this means the oil has leaked out and must be topped up. At the same time, change the O-Ring seals to prevent more leakage. Also check the damper shafts for damage. If they are scratched, change them as soon as possible.

   If the body shell of your Durango DESC210R is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your DESC210R model, fit an under guard to stop dirt and gravel entering the chassis.

Titanium Turnbuckles
   Examine the drive shafts for wear and replace as required. If possible, change them for titanium. The steel shafts wear and bend too easily.

   If you intend to race your DESC210R Truck model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   The gearbox of your used Truck should be opened up to check for gear wear and lubrication. A thin coat of grease is often used on internal gears and although this is fine for basic running around on the back yard, if you intend to race your Truck at a higher level, this should be removed and replaced with racing oil (ZX1 or Teflon Oil). Of course, this should be reapplied after each race meeting.

Spur Gears
   Gears are a weakness on all Truck RC models. Head on collisions can easily damage the gear teeth on nylon and plastic spur gears. Heavy impacts can also loosen the nuts or self tapping screws that hold the Electric Motor in Position, allowing the pinion gear to pull out of mesh slightly and rip the tops off the teeth on your spur gear. To minimise this possibility, fit bolts with locking nuts to the Electric Motor mount and remember to check them for security after every two or three runs.

   Ball joints always cause problems. For top level Electric Truck racing, the plastic ball connectors should be checked and if deemed necessary changed after every meeting. A simple thing like a loose fitting connector popping off could easily end your race, so better safe than sorry.

Servo Gears
   The DESC210R steering servo is also prone to damage. In high speed crash situations, the fragile gear teeth of the servo can be broken off, rendering your expensive servo useless, so be sure to obtain a good quality "Servo Saver". Check out my Servo Information article.

   If body roll on your Durango DESC210R is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers.

Ball Bearings
   If your used Durango Truck comes with plastic and sintered brass bushings (ring type bearings), check the shafts that run in them for wear. Dust and grit can get into these bearings and abrade the shafts. Therefore, you should replace them all with shielded ball bearings. If the model has been run with ring type bearings, you may have to change all the axles and driveshafts. For more information, take a look at my article, How to get the best from your Bearings.

   Finally, good luck with your DESC210R model and good racing.

Hints and Tips

Dampers

   Dampers, Shock Absorbers, Shocks call them what you will, they are one of the least understood, but most important tools you have for adjusting the handling characteristics of your RC model.

   In this article, I will endeavour to explain just what you can achieve by making simple tweaks to your shocks and how these tweaks can keep you ahead of your opposition on the track.

   In dictionary terms "Damper" is described as "A mechanical device to absorb the energy of sudden impulses." In plain language, they stop your car from bouncing all over the track.


So how do Dampers work?

   Basically what you have is a small amount of silicone oil contained in a sealed cylinder. Through the centre of that cylinder is a metal rod and on the end of that rod, a piston with a number of small holes in it. Pulling, or pushing the rod in and out of the cylinder, your will notice a certain amount of resistance as the oil is forced through the holes in the piston. To manipulate that resistance you have two options. You could use thicker or thinner oil, or change the size of the holes in the piston. So if you have thicker oil, or smaller holes, you have more resistance. Less viscous oil or larger holes, less resistance. This simple physical relationship, coupled with a good set of tuning springs, is all you need to set-up your car to beat the rest.

   Out on the race track, the main thing you want to avoid is your car bouncing around all over the place, sliding, or even rolling over when you negotiate a tight corner. To prevent this you need to make changes, but before you make those changes you need to consider what your problem is for that particular track. How your model reacts when cornering does it Under-steer? (Slide towards the outside of the corner) or Over-steer? (Turns towards the inside of the corner). Does it react differently when you exit the corner to how it did when you entered it?

   Once you have decided what your problem is, go to our "Set-Up" page linked below and follow the step by step instructions. But remember to only make ONE change at a time. If the first suggestion isn't enough to cure the problem, add the second and so on, until you find that perfect setting. Good luck and good racing.

Electric Motors for RC Models

Winds and Turns

Q/  What does 15x2 or 17x3 mean?
A/  The first number relates to the number of times the wires are wound round each of the 3 armature segments, the second number relates to the number of wires side by side. So a 15x2 would have 2 wires laid side by side and wrapped around each segment 15 times.

Q/  What is the difference in performance between a Low Turn motor (eg 11x1) and a High Turn motor (eg 27x1)?
A/  A Motor with Less Turns like an 11x1 means high current draw from the batteries which corresponds to less runtime, but More Power (Torque or Punch) Best for tracks with lots of corners and short straights where fast acceleration is needed. (use a small pinion)
Motors with More Turns like a 27x1 give you More runtime, but Less Power. So you get a smoother response and are therefore easier to drive. Better for less experienced drivers and Long straight, sweeping corner tracks. (with a large pinion) This is correct for Brushed, Modified and Stock Motors as well as Brushless Motors.

Q/  How do the number of winds effect a motor?
A/  A Motor with More Winds (number of wires eg 13x5) is less demanding on the battery and smoother in acceleration. Best for low grip, slippery tracks.
A Low Wind Motor (eg 11x1) is more punchy and can be difficult to handle. Best on high grip, hot weather Tarmac, or indoor carpet, high acceleration, low speed tracks.

Advance and Retard

Q/  What is Advance and Retard?
A/  On the Endbell of a Modified Motor (where the brushes fit) you will find two screws that hold the Endbell to the Can. If these screws are slackened off slightly the Endbell can then be twisted either Clockwise (Advance) or Anticlockwise (Retard). On Sensorless Brushless Motors this adjustment can generally be made in a similar way (although there are some Brushless Motors that have fixed timing for Spec level racing). Sensored Motors can be adjusted via the ESC.

Q/  What does "Advancing" the Endbell position do?
A/  Advancing the Endbell Reduces runtime, increases Punch (acceleration) and RPM to give a higher top speed.
On the down side, for Brushed Motors, the brushes wear faster and the increased current draw creates more arcing thus increased heat and Commutator (Comm) wear. Brushless Motors can lose some efficiency at the end of a race because of overheating due to increased current draw.

Q/  What does "Retarding" the Endbell position do?
A/  On both Brushed and Brushless Motors, Retarding the Endbell Increases runtime, decreases Punch (acceleration) and RPM to give a lower top speed and for Brushed Motors, brush wear and Commutator (Comm) wear is reduced.

Brushed Motor Basics

Q/  What is the effect of hard and soft Brushes?
A/  Basically, Hard brushes give a lower current draw, so consequently give longer run times and lower torque so less punch (acceleration)
Soft Brushes on the other hand increase current draw thus give higher torque and increased acceleration. Of course the down side of this is that Soft brushes wear much faster and must be changed more often. (I change mine when they get to around 5mm)

Q/  How does changing the brush spring change the motor?
A/  If you fit Stiffer Brush Springs your motor will have More power at low revs and also a lower top speed. I only ever fit stiff springs on bumpy tracks to reduce brush bounce.
Weaker springs reduce power but increase RPM so give less acceleration but a higher top speed. Good for long, sweeping, smooth tracks, where you can carry good speed through the corners.
