Ihave some questions about motors in general for the tanks we tend to work with.

1. What is the range of output voltages (assuming there are a range)or what is the steady voltage from the RX18 to each of the motors?

2. Is the power of the motor (and by that Imean torque) related to the voltage of the motor/voltage being delivered to it or the current (amps)?.

3. Is it possible to fit (or even buy) motors with very high torque? and by that Imean much higher than the stock motors.....

4. Where is it possible to buy things like the cogs, wheels and bits and pieces used in the gearboxes or parts for chain drives (ie. small drive chains and the like)?

5. Can a stock motor/gearbox combo be turned to 3:1 using a chain drive and appropriate cogs without dismantling the gearbox?

6. Are there any threads (I checked with no success from my side) that anyone knows of dealing with big powerful motors in 1:16 scale tanks?

7. Is there any measurement of strength (as in "pulling power"or whatever) that has come to be adopted by tank people? Like pushing a weight, or managing an incline or whatever?

Sorry for the questions. But somehow, no matter how heavy the tank or how realistically it sits on the tracks or whatever.....Ijust have the feeling that its not going to manage to come crashing through the wall of a house (appropriately scaled of course).

And Im after that feeling of grunt and muscle......

A further 3:1 gear reduction offers the best way to add grunt to a tank. Even with stock motors you will have the power you need to twist or break something if the tracks get jammed.

Mato Toys in Canada and Welsh Dragon models in the UK are a couple of examples of retailers who have what you need.

I will attempt to answer from a technical point:

1. What is the range of output voltages (assuming there are a range) or what is the steady voltage from the RX18 to each of the motors? Depends on the motor curve, most toy hobby motors peak efficiency about 6V

2. Is the power of the motor (and by that I mean torque) related to the voltage of the motor/voltage being delivered to it or the current (amps)?.
Amp draw will determine torque, more efficient motors have multiple armature windings and high permanant magnet structures or electromagnets

3. Is it possible to fit (or even buy) motors with very high torque? and by that I mean much higher than the stock motors.....
Yes indeed, look for the increased turns refered to as "T" in hobby motor windings for power (rather than speed)

4. Where is it possible to buy things like the cogs, wheels and bits and pieces used in the gearboxes or parts for chain drives (ie. small drive chains and the like)?
RC car and nitro transmissions have a wide variety of quality gears

5. Can a stock motor/gearbox combo be turned to 3:1 using a chain drive and appropriate cogs without dismantling the gearbox?
Yes, but takes up more space, unless you are mechanically inclined probably better to purchase a munufactured unit

6. Are there any threads ( I checked with no success from my side) that anyone knows of dealing with big powerful motors in 1:16 scale tanks?
Try searching for "lathe" or "55T lathe" type motors, lower speed increaseed torque for crawler RC trucks

7. Is there any measurement of strength (as in "pulling power" or whatever) that has come to be adopted by tank people? Like pushing a weight, or managing an incline or whatever?
Not that I know of but it would be interesting to have a"tractor pull" competition of tanks!

Just as an observation, but if you are going for scale realism, in my opinion, a system that gives you momentum is really needed.

Not sure if you thought about that or not, but the 3:1 gear reduction setups seem to provide plenty of torque no matter how heavy the vehicle (making further drivetrain mods unnecessary), but the way they start and stop is still unrealistic.

Im currently running the 3:1 set Igot from rctank and while its very nice it just doesnt seem .... accurate.

Is that on top of the 3:1 reduction Ihave already?

How would Iget that? By adding more mass to the tank? Ihad thought of trying to get the tank up to 14 kg or so (which by my caluclations is what a 1/16 tiger should weigh) just by sticking weight on top but Iam really scared about blowing out the board.

Now I understand your question.

The El-Mod electronics has a physics engine algorithm that simulates mass by tank class. This is all electronic control with no need for motor modification.

You'd need to go to one of the aftermarket electronic systems, like this: http://www.rctankwars.com/Battlecircuits.asp

You can add as much weight as you like, but an electric drivetrain (without something as linked above) in 1:16 scale will likely never correctly emulate the momentum/feel of a gas/diesel powered tank.

Thanks folks.

Ididnt know about these systems and the "momentum"thingys could be just what Im after!

Yes the Darkith battle system is a proven design and gives you momentum,battle sounds and IR capability. Phil can help you out or if you don't mind DIY kits uy directly from David[link=http://darkith.dyndns.org/~darkith/html/dbc_snd.shtml]Davids Battle Circuit[/link]
