How can I tell what this motor / battery will power?

[Andy C]

So I haven't used my Seagull EPioneer for a couple of years and don't know if my daughters will ever use it so thought it might be worth making use of the motor, ESC and batteries for another plane.  I have variuos kits and also old waiting to restore planes, but don't know what this would power.

Motor is Turnigy C3548-1100

Batteries are 3S, 4000mAh, 30-40C. (I have 4 of these so really want to use them ? )

Thanks all

What power does it give on the prop used on the E-pioneer? Must be upwards of 400W? So something bigger than Peter Millard recent electric models (50"-ish aerobatic). Or something much bigger and vintage and slow, 90" vintage at 9lbs.

I've got much the same in a Sukhoi 29 30-E which is a 49" aerobat.  Goes quite nicely in that.

I have one in a VQ Tigermoth 12x5 prop on 4S weight 7.5 pounds, not very aerobatic more like scale.

Another in a 60" Jensen Ugly stik built from a plan pack 12x6 prop again on 4S weight 5.5 pounds flies like a trainer, no startling performance.

Thanks for the replies guys although I am still not sure how to work with this.  Is there any way of understanding how this power compares to an IC engine.  That might at least give me an idea.  Could I compare this to a 40 4 stroke for instance?

That would be my guess.

How old are your 4000 mAh batteries? If they are LiPo they do tend to loose both capacity and effective C rating over time. Depending on the storage conditions and charge level the loss can be quite significant after 2 or 3 years. .
