Buying a Used Losi Mini-Baja Truck (and What to look for)


   Buying a used Losi Mini-Baja 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 Losi 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 Losi 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 Losi 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 Losi Mini-Baja 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 Mini-Baja 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 Mini-Baja 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 Mini-Baja 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 Losi Mini-Baja 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 Losi 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 Mini-Baja model and good racing.

Hints and Tips

Anti Squat

   Described as the angle at which the suspension arms pivot in relation to the chassis, Anti Squat effects traction under acceleration.

   Considered to be at its most effective from a standing start, the handling and stability of the majority of modern day On Road and an increasing number of Off Road models, can be improved with a certain amount of anti squat, normally no more than around 3 degrees.

   Basically, more anti squat gives you more traction, but after a certain point, that advantage is lost and the car will become unstable when turning into high speed corners. For Off Road models anti squat can also improve how the car handles on bumpy tracks.

   Less anti squat allows the car to drop at the rear under hard acceleration, providing less traction, but more stable when cornering. If no anti squat is present, with the lower suspension pivot shaft being parallel to the chassis, steering will be sharp and can induce some over-steer.

   Most manufacturers have some anti squat on their car kits provided as standard and hop-up parts are generally available to change the anti squat angle, but more often, on a wide range of models, all that is needed is a washer or two under one side of the suspension pivot block. However, if the block is held in position using self tapping screws, it may be prudent to change them for slightly longer ones.

   If you are thinking of trying a different setting on your car, not just for anti squat, always remember to only make one change at a time. Too many changes to your set-up made at one time, can make it difficult, if not impossible, to determine which change you made gave you the result you desired.

Hints and Tips


Electric Motors for RC Models

Brushless Motor Basics

   Choosing the right Brushless motor for your needs can be a daunting task for those new to Radio Controlled Models. If you have a local club perhaps you could ask some of the more experienced members for their advice, but a little basic knowledge about the subject, so you know what questions to ask is always useful.

   All Brushless motors are rated by Kilovolts (KV) and is an indication of the revs per minute (RPM) that particular Motor can attain running freely, under no load conditions, per Volt of input.

   For Example: To calculate the Maximum RPM of a Motor listed at 4000 KV, connected to a 7.4 Volt Battery, simply multiply the two: 4000 x 7.4 = 29600 RPM.

   The two main types of Brushless Motors used in RC are Sensored and a Sensorless Motors.
   Sensored Motors can be connected directly using s cable, to the Electronic Speed Controller (ESC). The ESC is then able to monitor the performance of the Motor and regulate Current output, to attain smooth, controlled acceleration. Advance and Retard timing is made automatically by the ERSC to change torque when exiting corners and give you more RPM for long straights.

   Sensorless Motors can only be set manually for Advance and Retard timing and once that setting is made you have to stick with it. For obvious reasons, Sensorless motors are cheaper to buy than the Sensored type: Ideal if you just want to bash around in the back yard, but not so much if you are serious about your racing.

   Brushless Motors, need a reasonable amount of maintenance if they are to remain competitive. For top level racing I recommend you strip, clean and re-oil the bearings every 2 or 3 meetings (Check out our "get the best from your bearings" section).
   Gearing your motor correctly for any given track is always important. (Check out my Gearing tips on the Pinions Section of this site) A cool motor is an efficient motor. As your motor heats up towards the end of a race, it will loose efficiency. Gearing correctly can avoid this problem to some degree and simply following my simple guidelines, described in the aforementioned article can help you not only keep your motor running efficiently, but help you stay in front of your opposition.

   One last tip .. When re-building your Brushless Motor, to safely replace the Rotor, use a rolled up piece of paper and place it into the Can. This will protect your rotor against damage. Then carefully remove the paper before replacing the endbell.
