Just wanted some information on the old 4.5V motor that was used in Technic models until about 1989 or 1990. It appears that the 8050, 8054, 8055 and 8700 sets coame with this type of motor. What is the general rotational speed of it? (is it really (...) (23 years ago, 19-Jan-01, to lugnet.technic)

(...) They were about as fast as the standard 9V motor, but less powerful. To move larger models you needed the 872 gearbox set. It wasn't the voltage that gave it so little power... the 12v motor (as in 880) is just as strong (or weak) Also there (...) (23 years ago, 19-Jan-01, to lugnet.technic)

(...) I read this at work and thought, I have recently dug out my 8865 instructions and assembled the alternate model (URL) later motorized it with a 4.5 volt motor and I sure don't remember any second set of motorization instructions. But there it (...) (23 years ago, 20-Jan-01, to lugnet.technic)

(...) Okay I see; thanks for the information. The 12V motor is not any more powerful than the 4.5V one? That's strange...I wonder why it was released at the same time as the 4.5V one (when it was nearly identical to it); the only other difference (...) (23 years ago, 23-Jan-01, to lugnet.technic)

Yeah, the springs on these yellow shock absorbers are much stiffer than the normal ones. Although on the Silver Champion, even they are not enough to hold up the chassis properly (sometimes when it is pushed down, it stays down). They work quite (...) (23 years ago, 23-Jan-01, to lugnet.technic)

(...) 12v didn't require those darned batteries... if you already had a 12v transformer it would be a waste of money (if you check out the image of the 880 set, you'll notice it has the special plug meant for the 12v transformers) LEGO even adapted (...) (23 years ago, 23-Jan-01, to lugnet.technic)
