gezocht graupner 700 BB turbo motoren

[Mischa]

Gezien de levering momenteel niet mogelijk is vraag ik jullie of er nog ergens graupner speed 700 BB turbo motoren (bestelnummer 6317)rondslingeren die ik zou mogen overnemen. Of wellicht weten jullie er nog een paar te koop bij een plaatselijke modelbouwwinkel.

Alvast dank!

ik heb er 2 liggen, maar die hebben bestelnummer 3308.
Speed 700 Turbo 9.6V
Ik weet wat het verschil is. Maar die mag je wel over kopen.

De 6317 is de 12V versie, de 3308 is de 9,6V versie.

[Mischa]

Ik heb echt de 12 volt versie nodig. De 9,6 versie kan ik gewoon bestellen, maar het is het bekijken waard.

This cheap 200W motor is worth to take a look on:

They are indeed interesting, specially for that price.

voor dat geld durf je nog eens te experimenteren..

Even taking in the extra gearing to get an acceptable speed with a normal wheelsize, it's a cheap motor.

The Torque is especialy good. Even higher than that from the Speed 900, what has 1.1nm on 12V.
On the other hand, that means stall takes a lot more amps than 21A.

I guess 21A can be seen as the useable power for the drive.

I would say. 100mm wheel, 2 stage gearing with a total gearratio 19-1.

Hey, that sounds as Prodigy Evo with the speed 700 Turbo C.

On the other hand, that means stall takes a lot more amps than 21A.

Thats right, i testet the stall current one minute ago, its around 130 A !
Very important to build a good gearing.

Specs komen aardig overeen met de Turbo C motor. Extra accupakje is dan geen overbodige luxe.

voor dat geld durf je nog eens te experimenteren..

In dat geval: REGEL HET!

[maddox]

Those aren't close to the Speed 700 Turbo C's, those are Turbo C's.

Pity they don't have the larger ones.

Our Techchecker said that these motors are allowed for Raptor´s

[inventor]

We know, these where fitted in the first version of NPOW (Nebelwerfer)

[wisefire]

i dont have enough knowledge to know if these motors are suitable for featherweights. does anyone know the weight? also 120A on stall is quite a high number indeed. wouldnt wanna blow up my speedos..

however im willing to experiment with these.. anyone else want in.. i think, the shipping cost will be lower when we get them all shipped to holland in one box .

There is nothing to experiment, we know they work. As long as you gear them down properly the amps stay down as well.
