4500KV is well above the 2100KV that 6S builds use, whatever the propeller. This is a motor for fewer cells: on this pack it will run far past what its propeller and ESC were sized for.

4500KV on 1S is outside the usual range. It will fly, but expect heat or lost punch.

This listing does not say which warehouse ships it. Most orders leave China, so expect import VAT and a carrier handling fee unless an EU warehouse is chosen at checkout.
No current price: our own estimate is 180 SEK. It is a rough street figure rather than a quote, and the retailer above confirms the real one.
Some links on this page earn us a commission at no extra cost to you, and that never affects any verdict on it. How this is funded.
Recorded specification
Every value carries the source it was read from. A property with no recorded source is marked as such rather than presented as a fact. If one of them is wrong, tell us: it is the fastest way it gets fixed.
