1/5 Scale Nitro Touring Car:

Himoto Megap MTC-5 - HI7505
Radio Controlled Model



History and Info:

   Introduced by Himoto Racing circa 2010, the Megap MTC-5 Touring Car, was available RTR with a 23cc engine - # HI7505 - a 26cc engine - # HI7505-26 - a 30cc engine - # HI7505-30 - or an Upgrade version - # HI7505M - and radio system.

   The 4WD model is shaft driven, on an alloy plate chassis, with gear type differentials, coil spring over oil filled dampers, dogbone drive-shafts and ball bearings.

   To race the Himoto Megap MTC-5, it requires time and patience, to tune and adjust for improvements in handling and steering ability and to get the grip you need to stay on course when manoeuvring around tight, slippery corners. A little can be a lot when it comes to changing your cars settings and our easy methodical directions will guide you to the best Set-up to help you win and keep you winning.

Buying a Used Himoto Megap MTC-5
Touring Car (and What to look for)


   There are essentially three reasons you might want to buy a used Himoto Megap MTC-5 Nitro Touring Car; 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 Himoto website, or purchased separately on eBay. With an instruction manual, any problems with your model Touring Car you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
   When you receive your used Himoto Touring Car, 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 Himoto 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 Himoto Megap MTC-5 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 Megap MTC-5 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 Megap MTC-5 Touring Car 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 Touring Car 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 road, if you intend to race your Touring Car 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

Spur Gears
   Gears are a weakness on all Touring Car 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 Nitro Engine 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 Nitro Engine 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 Nitro Touring Car 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 Megap MTC-5 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 Himoto Megap MTC-5 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

Ball Bearings
   If your used Himoto Touring Car 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 Megap MTC-5 model and good racing.

Hints, Tips and Information

Preparing your New Nitro Engine

1/   New RC Gas Engines need running or "breaking" in before being used competitively. 2 or 3 tanks of fuel are usually enough, but don't over rev the engine and try to keep it cool, below 160 degrees F (71 degrees C)

2/   To maximise your RC Gas engines power reduce air leaks as much as possible by using silicone sealant or high temperature gaskets where the carburettor and the exhaust manifold joins the engine block.

3/   As a rule, try to keep your engine temperature at around 210 F (99 C) and no higher than 225 degrees F (107 degrees C). If your engine temperature is higher than 225 F (107 C) try tweaking the mixture a little richer. If too cool (below 200 degrees F (93 degrees C)) tweak the mixture a little leaner.

Hints, Tips and Information

Look after your Gears

   In RC there are a number of different gear teeth sizes we tend to use, based on two systems. Imperial and metric.

   The imperial system has sizes 24dp, 32dp, 48dp and 64dp. DP stands for Diametral Pitch and the number refers to the number of teeth per inch.

   The metric system has sizes 0.4m, 0.5m, 0.6m, 0.7m, 0.8m and 1m. M stands for Module and is the ratio of the reference diameter of the gear divided by the number of teeth.

   The different sizes are used basically for strength. 32dp gear teeth are larger than 64dp gear teeth, therefore the 32dp gears are by design stronger and for this reason are more commonly used on a number of entry level buggys, to help them withstand the knocks and crashes by drivers new to RC, and nitro models because of the higher torque levels involved. Also, the bigger the scale of the model, the stronger the teeth need to be.
