Scaled down to 1/16th, the Challenger 2 has a top road speed of 3.4 feet per second and 2.3 feet per second off road. In comparison, the Tiger 1 had a maximum road speed of 2.6 feet per second, 1.5 feet per second off road. To get the true scale speed you need to take the actual speed in mph and multiply it by 0.09167 and you get a model speed in feet per second.

Which is plenty fast enough for us old folk to keep up with ;)

Is it expected that with upgrade metal drivetrain components you sacrifice speed?

Don't forget that the diameter of the drive sprocket affects speed too.

You don't really have to sacrifice speed. If you go from 3 to 1 to 4 to 1 you will have less top speed, but some bigger Motors will help with that. I think the main reason most guys like the 4 to 1 is because it does have better low speed control because it has more torque. Can you post photos of the gearbox you have right now?

Isn't it just possible to manage speed with delicate manipulation of the TX toggles?
Time and practice can give good results, I think...

I would imagins so - BUT - a weak, underpowered motor will need a firmer touch in order to generate sufficient force to overcome initial resistance. Especially if you have upgraded the running gear to metal. I bought the HL Pro version of the Challenger (metal gearbox, metal tracks, wheels etc) and it simply would not "creep" !!! I found it very stop and go on rough surfaces, not so bad on smooth flooring.

Now I can go from a gentle creep to full speed ahead with plenty of control (when I've practiced the delicate touch a bit more LOL)

Our model tanks suffer from low spec. brushed motors and cheap propriatory electronic speed controllers (ESC) built into the mfu. In terms of smooth running, nylon geared boxes with plastic wheels and tracks would be better (but we all want metal!). If we were prepared to spend lots more we would have none of these problems but then we would all be using 'hobby grade' electronics in our vehicles, rather like the car racers, boat builders, truck modellers, aircraft modellers and so on. Shame on us!! :{

If I am spending £1,000 for a 1/16 scale Tank I do not think it unreasonable to expect to find a decent electronics suite fitted as standard.
I think I am about to upset someone :haha:
