Motor for 22-24 lbs 3D/IMAC model

Hello.
I am looking for a suitable motor for a 3D/IMAC model weighing 22-24 lbs.
I run electric F3A, and therefore have a number of 10s5Ah packs which I want to use as 10s2p (10 Ah)
(This is also what is commonly used in the German F3A-X class, I believe.)

1. Will the 1527-series of motor be able to deliver up to 5kW+ short term?
(e.g. the 1527-1Y, effective kv=1250/6.7=186, or the 1527-2D, effektive kv=1150/6.7=172)

2. Alternatively, would a geared 2215 be suitable for 10s?
(2215-1Y, effective kv=1440/6.7=215 which is ok, but voltage limited to 30V, I assume 35-36V under load for a 10s pack. 2215-1.5Y, effective kv=1020/6.7=152, which may be fine for 12s packs, but probably too low for 10s.)

What do you recommend?

3. What is the current delivery time for these motors?

Kind regards,
Magne

For a light weight system I think the 1527 size would be the way to go. Production time is in the 3-4 week range now.

Thanks

Thank you.

On a slightly larger plane, can the Neu 2230-3Y (kv=240) be used directly without a gearbox?
(on 10s3p, total 15 Ah, estimated 7-8 kW peak)
Is the 8mm shaft going to be strong enough?
Is the 8mm prop adapter strong enough?

Regards,
Magne
