Default Foamboard Delta - motor question

Hi Guys - it's been a while since I visited!

The UK weather has been miserable today so I decided to build something!
As I have some 350, 500 850 and 1000 MaH 3S batteries I decided a 24" delta might be a fun project so concocted one in my head as I went along, I decided on a tractor configuration.
I bought some paper covered foam board from a local craft shop and I had 9g servos 18A ESC and several motors lying around so it was virtually a freebie! However I have a question!
I decided that I would use an Eflite 300 outrunner and prop from a crashed Eflite P40 warhawk to power the plane. It's 1380KV and the prop is a 7 x 6 . When I checked the specs on the P40 it was 6.6oz flying weight but my design is coming in at 9.2oz (including battery etc) I'm wondering if this motor/prop will be powerful enough? Your thoughts please?
