Which is more powerful? 450 or 480 motor??

Hi

This might be a stupid question but I'm still new in this hobby. I was wondering which motor is more powerful one, 450 or 480 motor? I get the impression that the 450 is
more powerful. Am I right or do I have everything mixed up?

Thanks

Al

There is only one 450 I am aware of, but a whole bunch of 480's. Which did you have in mind?

I guess the one I have in mind is the Permax 450 and Permax 480 or Graupner 480.

The Graupner Speed 480 (of which there are at least 5 varients) is nothing like the Multiplex Permax 480. The Permax 480 is just a longer version of the speed 400. The true Speed 480 models are much larger and heavier - in a similar power class to the Multiplex Turbo 450 (which is also heavier, and rated for higher power, than the Permax 480). That doesn't mean you'll get more power by just plugging it in, however. You need a larger prop to extract more power with a turbo 450, for the same cell count.

So is the Graupner considered the true speed 480? If not, which brand is the true S480?
Thanks

Hi Al,

It gets even more complicated. Graupner has the Speed 480, the Speed 480L, The Speed 480 Race and a Speed 480 Race BB (which is actually the same motor as the Multiplex Permax 400BB!). But perhaps we can agree on that the "real 480" is a 100g motor in a Sagami can? Jürgen

I'm not surprised!

The 480s are about 1/2" longer and about 1oz heavier than the 400s. The Permax and Jamara 480s are "long can" 400s and use the same 2.3mm shaft.

The Graupner 480s are about 1/16" larger diameter than a 400, have a 3.2mm (1/8") shaft, and replaceable brushes. My favourite of the bunch as a 400 upgrade is the #6304 Speed 480 7.2v (available from Hobby Lobby) which works well with 7 or 8 cells, and 6x4 props.

The Permax 450 has a 3.2mm shaft with replaceable brushes, and is a mid size between the 480s and 600s (yes, it confused me to start with!)

Regards, John

Depends which airframe you have in mind, and what you hope to get out of it - improved performance, longer duration? Do you want to use better cells or a larger prop, or both? It's not as simple as "motor X is a drop in replacement for the speed 400". In fact, WHICH speed 400 do you have? There are 4 different models - although I suspect it's a 6V, which means the Permax 480 would be a small upgrade (a lot of people have used them). It would be simple, too, as it's the same diameter and shaft, just longer. It's only around $10, also..

If you have a 6V 400 and want an increase in power without going up to bigger batteries etc. The 480 is the way to go.
IMHO this motor needs the 8 cell packs to do good however. I like the 480 with a 6X4 and 8 cells. For $10.00 it is not a bad deal.

Poobs - his whole problem, and the point of this topic, is - WHICH 480 - but I think you mean the Permax 480. BTW, it's available under many different labels (Dymond has it as their Max 480, so does EAM as PRO 480 I think - EAM carries all three versions).
