9v motors (should lego make them again?)

[Boxerlego]

I have a Grasshopper (and many other Tamiya RCs) and it does most definitely not have awesome performance, in fact it's probably one of the worst Tamiyas. Sure is a lot of fun to drive though

I do understand what a V8 is, do you know what a Fiat 500 is? What this has to with Monster Trucks, beats me

If you want to learn about 'large size' motors you should have picked another medium than LEGO, proper RC would be my choice

Well the grasshopper was the only RC I ever had. For me it had awesome performance because I have nothing else. Seeing today RCs no wonder you say it does not have awesome performance

I know what a fiat 500 is. Its the car that monster truck drives over. I'm kidding there It comes from Italy and is the economical choice. right? Yes I understand your comparison and I agree with it. I just wanted to share with you and everyone my reasons and comparison and why I used the monster truck for my disambiguation.

Way off topic, but the (real-life) monster trucks I've seen use heavy-duty axles, diffs, props, hubs, swingarms, shocks, clutches etc, either custom-made, or from severe-duty trucks and heavy equipment. They don't just stick a V8 into a mass-production vehicle.

The point being that hopping up Lego with excessive power just reveals problems,

- high-torque reveals the weaknesses of ABS parts (even a single XL motor will split gears and twist axles easily)

- high-speed reveals the problems of a using low-melting point parts in a high-friction, unlubricated, no-bearings environment

- high torque and high shock loadings show the limits of pins, axles and studs to keep parts together

- high torque shows how poorly beams and liftarms resist bending moments, causing gear trains etc to come unmeshed

Anyway, just my 2p

Very well put. My sentiments are the same with this post. Even for the power in the Lego motors can reveals problems but remember that there're always solutions.

This is also why I stick to old 9v

I too wish that they have a come back to the 9v system in a particularly ways for the PF system, Yea the wires are rubbish but the style of brick connections are not. I wish that they would bring back those connections the new style I have some that are either way to hard to take apart or doesn't snap together and comes easily apart. I remember blakbird talking about saving space on the PF wire connection to the motors because the wire leading to the motors two of them are actually needed. I don't like the wires coming out of motor this limits length. I would perefer having a variable select able lengths of wire connection that can go in between the receiver and motor, so you never having to either dealing with too much wire or too less. Returning back to the 9v system on how the motors connected up with the wire that would be something worth returning back too. What do you think 9v system. Agree or Disagree

[andythenorth]

However with the 9V LEGO motors there doesn't ever seem to be enough current or heat to be noticeable.

Yeah, had them plugged into things like this

Hmm that thing can provide up to 8 amps. enough to melt something if the motor is stalled.

[NorthernRPG]

I think that the Lego PF system is very good but a few things could be changed

Motors:

Apparently using the large train wheels on the train motor is not recommended so I think they should make a motor specially for large train wheels.

They should make a small motor like the micromotor for places that a light motor is required

IR system:

The current version is fine but it could use extra range.

Battery boxes:

These annoy me. The current 3 battery boxes are good but they are quite big and if there is limited space available can lead to a lot of frustration. I am currently trying to RC my 42000 my own way and I realized that 1 battery box wouldn't be enough so I attempted to fit an 8878 but it wouldn't fit so I dipped into my small supply of 9V battery boxes and came up with one that only required 1 9V battery. It was small and light and more than sufficient for my needs. So maybe they could bring back a 9V battery box but with a PF connector?

[andythenorth]

9V batteries are crap, expensive, and they don't hold charge for long enough to use in technic vehicles, or in trains that your kids want to run around around and around around

But the PF battery boxes are annoying.

The AA box is too tight for most NiMh batteries, I have to pry them out with a screwdriver or the battery box lid, which splits the plastic cover on the battery.

The AA box is also large, sometimes trading battery life for size would be good.

But the AAA box has some shortcomings. There's the stupid screw (not stupid if your toddler eats batteries) but the screw makes changing batteries a chore (I break them out and am teaching my kids to stop eating batteries).

The AAA box also has no stud mounting points (adding them would make it longer, wider, or taller). For whatever reason (not sure myself), I never think of using the AAA box in technic mocs.

Would be neat to have boxes holding 2xAA (total 3v) that could be ganged together, but eh, that's way too complex and won't happen.

Try stalling a Micromotor with the pulley thing removed. It's dead instantly and for good.

I think someone should make signature for me

Missread you, sorry! Yeah, won't do that then

Delicate thingies they are :

Hmm, that's probably why the motor doesn't have an axle output. The pulley is the only way to use it and the pulley is not tight enough to stall the motor. However if you stall it with your fingers....

I don't think the 'criticism' from Bonox is intended as criticism, it's curiosity about why you want 9V back.

precisely - I can't work out if 9V is coming from an objective position and just not getting it across well, or else not having much knowledge of the new stuff (like appearing to know nothing of 9V/PF compatibility) or perhaps just having a very dark tint on the rose coloured glasses like listening to my grand-dad talk about stuff from his past. Nevertheless, I'm still interested in why people think the way they do, hoping for objective points of comparison rather than saying the old one is better just because they made it and not because there's a limitation of the new stuff.

Edit: I've got an 8480 that i've given up on getting a working micromotor for since they're so expensive, but i've decided to try and put a dead one in just to make the satellite look right and I can't even find one of those for what I would call realistic money. Anyone know of a source of dead units?

defiantly agree

+1 for 9v motors thread! Its a great idea, glad to help make you point clear for everyone. a little confusing at first but now I understand where your getting at

look at brick link Edited November 27, 2014 by 9v system

[whale2]

Well, if we agree than "TLG should make some motor again" - what will happen?

(However, PF-styled micromotor is a dream :) )

[bonox]

look at brick link

Been looking at BL for months; all are specced as working or unknown and priced as working. e30 or more is not what I call realistic for a known dead unit, and they're not being sold as dead - they're being sold as "it might be working". It's getting close to gluing a pully to a 2x2 brick.

[9v system]

there was one on there for 10$

There is a special place in TLG for AFOL wishes, is the place where dreams go to die, where hope kills itself and innovation is hammered to the ground.

I think they call it board meeting.

It's funny because it's true. Really, though, I do think they "care" about us - we have money, too, after all. But they won't do something that is guaranteed to lose them money - like make 9V train motors again.

[N-4K0]

Fact is, us adult fans of Lego have far more money and opportunity to buy sets, but I guess there's far less of us, putting us at a risk when it comes to creating sets especially for us older builders.

[9v system]

What about a new type of control centre?

[andythenorth]

What would it do?

[9v system]

What would it do?

Have the same or similar functions as the 9v one be be compatible with pf and 9v

[dikkie klijn]

But the old one is basically compatible with the pf system, just use an extension wire.

[andythenorth]

I dunno, how would I control the old control center with the PF IR receiver?
