Buying a Used Thunder Tiger Phoenix BX II
Buggy (and What to look for)

There are essentially three reasons you might want to buy a used Thunder Tiger Phoenix BX II Electric Buggy; 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 Buggy you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
When you receive your used Thunder Tiger Buggy, 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 BX 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 BX 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 BX II Buggy 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 Buggy 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 Buggy 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 Buggy 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 Buggy 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 BX 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 BX 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 Buggy 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 BX II model and good racing.

Hints, Tips and Information

Battery Connectors

   Over the years I have been racing radio controlled model cars of all descriptions, I have tried a number of different connectors for my batteries.

   My first car was a Tamiya Boomerang, and of course the batteries I used all had the standard Tamiya connectors, which were fine with the kit supplied 27T silver can electric motor, but I soon discovered their problem when I installed my first Modified motor. The high current demands of the motor created so much heat, the plastic surround of the connectors melted and fused together. No matter how I tried they could not be disconnected. My only option was to cut the wires.

   From there I moved over to Corally connectors, commonly referred to by many now as Bullet connectors. Comprising of a short length of 4mm gold plated tube at one end, and what looks like what we used to call a Chinese lantern fitting that slotted inside the tube, also gold plated. Although they were highly efficient and reasonably easy to install and use, I never really took to this type of connector, I think it was the fact that there was always the possibility of the positive and negative being connected wrongly in poor light, and also that if positioned side by side, each connector could work loose and become exposed, leaving the possibility of a short circuit.

Hints, Tips and Information

Ride Height

To allow the suspension on any RC model to do its work properly, it needs to ride in a position where it is able to react to any bumps and holes it may encounter on the track. Therefore, it needs to be adjusted to somewhere in-between those limits. That position is commonly termed "ground clearance" or "ride height" and is generally measured as the distance between the underside of the chassis and the ground, with the motor and battery etc installed.

Simply speaking, determining the optimum ride height is dependent on the specific track conditions and "droop" setting (see my previous article). For Off Road models the rule is simple, the bigger the bumps and the deeper the holes, the higher the ride height. And for On Road, the lower the ride height, the better.
