I then tried to unscrew it to examine it but found it stripped the rings and now it doesn't go back and forth at all, it just wiggles around! It won't come off at all, no matter how much pressure i apply! The propeller blade screws also got too tight to screw in all the way.
Now i'm thinking i have to get a new motor shaft and propeller fixing bolt

Hi Ryan, the blades were facing the right way, they had a special tab that indicated which way was up. But ill be spending all afternoon dissembling Spitty number 1. Thanks for welcoming me on hobbysquak gents.
Motionrc has awesome customer support and i will always buy my airplanes from them when they are available.

When I chatted with Motion about getting a new propeller/motor shaft for mine to replace my stripped out one they said that there is another container coming in 4 weeks and the compliment of the parts would most likely be on there. So don't strike a prop until next month or you'll be parked in the Hanger like me until then!

So, I "Y" connected gear, flaps and ailerons and everything works accept the lights don't work now as there's no power to the blue box.
I may has to fiddle with hooking things up to the box one at a time and see what is what. Maybe the gear are supposed to be in "gear door"? I remember on the 90mm F-104 the "green board" was mis programmed and it took awhile to figure out what was what.

WARNING : Propeller Nut Binding
OK, thought the assembly was going marvelous until I tried installing the propeller assembly. Before I actually tried installing the prop assembly onto the motor I tested the main prop nut on the shaft to make sure there were no binding or threading issues. They went on smoothly by themselves.
When installing the prop hub, at about the half way point the prop nut was getting pretty stiff and I thought I'd better back it off to see what the problem was. I could feel a little gritty chatter backing the nut off. After inspecting the shaft and looking in the prop nut the threads appeared OK.
Looking further at the parts, I noticed there where curls of shaved plastic on the inside of the prop hub like they were scraped and pushed forward. I then looked at the propeller shaft and noticed the locking ridge that has the 4 bolts that bolt to the motor had a very sharp edge and that is what was plowing the plastic. I'm pretty sure this is probably what was causing the resistance to installing the main prop nut.
So, I took a file and lightly chamfered the edge, just a little to knock off the sharp edge. Thinking I was good to go I tried re-installing the prop assembly but only got about 3/4 of the way on when the prop nut started getting really tight again. I then started to back it off and got about 4 threads out when it seized going out. I can move it a couple turns on and off but will probably tear out the threads to get it all the way off.
I spoke to Wayne at MotionRC and he's going to see what he can do to get parts in more quickly. Those guys are the best!
Fortunately I have second Spitfire for my "project" that I can scavenge parts to get one going until the extra parts arrive.
This is a word of caution for those that haven't yet assembled their new Spitfires. If you get any significant resistance putting your main prop nut on stop! Don't dork up or seize your threads! Maybe put some teflon thread lube on and a lock washer before installing.

Here is the relevant part of the build overview video that shows this.

WARNING : Propeller Nut Binding
Had to get the nut off. Bent an allen wrench so had to take a vise grips. As expected snapped it right off.
In the photo of the hub, after I got it off for the second time, you can now clearly see the plastic was still damming up from the edge of the shaft shoulder. You can see the dark line is as far as it got onto the shaft.
Now, the problem is getting the 4 screws out to take the shaft off. Those puppies are tight! Think I already stripped one but will resharpen my allen wrench, apply some heat and have another go at it. Hate to think I'll need a whole motor assembly with shaft.

After taking the blades off I inspected the hub a little closer. I numbered each side for reference. If you look at each photo there is a stress point/crack forming just off center on each side. Looking on the inside, you can see there is a dark line directly behind where each stress point is forming.
So, either the motor shaft is machined too large, or more likely the plastic hub was ejected from it's mold too soon without proper cooling and the inside dimension shrunk. I'm betting it's the prop hub is misshaped or too small where it fits on the shaft shoulders.
I'm wondering now if the tightening the blade screws had something to do with it. Maybe the hub should be installed on the shaft before attaching the propeller blades?
