Buying a Used Thunder Tiger Phoenix ST II
Truck (and What to look for)

There are essentially three reasons you might want to buy a used Thunder Tiger Phoenix ST II Electric Truck; you may be a collector, looking to restore and display it; restore and sell for a profit; or simply restore and race an iconic vintage model. Personally, I used to get a buzz out of restoring an old clapped-out model, installing modern day electrics and maybe a few hop-ups, then showing the gang at our local club, just how competitive those old models could still be.

Cheap, pre-loved bargain models, parts and spares are always coming up for sale, but once you have made your purchase, the one thing you will always need, is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Thunder-Tiger website, or purchased separately on eBay. With an instruction manual, any problems with your model Truck you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
When you receive your used Thunder Tiger 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 Thunder Tiger 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.

Check the Body-Shell

If the body shell of your Thunder Tiger Phoenix ST II 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 Phoenix ST II model, fit an under guard to stop dirt and gravel entering the chassis.

Drive Shafts and Turnbuckles

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 Phoenix ST II Truck model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

Examine the Drive System

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.

Pinions and 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.

Don't Neglect the Ball-Joints

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.

Steering Servo and Servo-Saver

Servo Gears
The Phoenix ST II 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.

Stabilizers

If body roll on your Thunder Tiger Phoenix ST II 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.

Don't Forget those Bearings

If your used Thunder Tiger 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 Phoenix ST II model and good racing.

Hints, Tips and Information

Bearing Seals

   If you were to ask anyone with a modicum of experience in RC, they will tell you that the best modification you can make to a basic RC model, is to add a set of ball bearings.

   Quite a few of the entrance level models at the time this article was written, come with plastic and sintered brass ring type bearings. If these bearings are installed in the model and coated with grease as advised in the car manual, dust and grit can be caught in that grease and be dragged into the bearing where it can abrade the shaft that spins in it and it won't be long before it becomes a very sloppy fit, causing all kinds of problems.

   But what should you look for when buying bearings? There are a number of types of seal used on ball bearings, and there is much debate concerning which is the best for RC.

Electronic Speed Controllers

History

   ESC were originally developed to be used in conjunction with brushed 27T stock and modified motors in the late 1970s, early 1980s. Compared to modern day Controllers, they were Bulky and heavy, constructed using basic resistors, rheostats, capacitors and transistors, crammed together on a simple circuit board, to provide stepped but smooth acceleration when compared to the old mechanical, servo operated sweeper Speed Controllers. An Electronic Switch to change the direction of current flow was used on some of these early ESC to give reverse operation. Although they were a vast improvement on the old mechanical speedos of the time, they were expensive, jerky to control, and prone to burn out if not carefully looked after.

   As new technology became available, improvements were slowly made, and with the introduction of the new FET (Field Effect Transistors) and some basic mass produced silicon chips, ESC were made smaller and their reliability gradually improved.

   By the mid 1990s, "regenerative breaking" was developed. This meant that energy that would have been lost slowing down the car by effectively turning the motor into a generator, was harvested and put back into the battery. This of course was long before F1 had KERS (Kinetic Energy Recovery System) and adjustable anti lock breaking was introduced.
