What's hotter than a S400?

Ok, except for going up to a brushless motor or "bigger" motor, what motors would give a better performance than a stock S400, say, for less than $35?

Assume staying with a 7 cell pack and same ESC as comes with the Sky Scooter Pro.

Turbo 450. It puts out way more power then a 400. Amp draw will increase though, so you'll have to watch your packs. Are you using a geared setup or direct drive? The 450 is also a bit heavier---rob

Be sure you are using a 6 volt vs the 7.2 volt version.
Ball bearing version also has more kick

Does the 450 put out more rpm's? K/V?

Possibly the Multiplex Permax 400BB. I haven't tried it but I have heard good things about this motor.

The Multiplex Turbo 450 is a LOT heavier than an S400, and is actually a slower motor (lower Kv), so though it is more efficient, I wouldn't describe it as "hotter".

Change the timing on the S400.

Ok, so EXACTLY what are you referring to when you say "hotter"? More overall power or what? My friend Greg, uses a Rocket 400 which if I remember correctly is a 4.8 volt speed 400. It of course does not have a very long life span.

Most of us that fly Zagis use the 450 turbo to increase our performance. You can swing a larger prop with it then the 400, I use a 6x5 Aeronaut. It is definately a Hotter/faster setup. It also fits most places that a 400 does. It is priced under $30----Rob

Is the Turbo 450 the same diameter as speed 400?!
