In your case it looks like #3, the backplate, is that flat washer.


Here's an idea of how to mount the stock spinner until you get a new one. Ream out the hole in the bottom part, of course.




Hope this helps.




Thats brilliant help mate thanks very much for that.
1 more silly question tho lol
By looking at mine do you know what my radial mount is or have I not got 1 ?
P.s Ive just noticed my name on the motor LOL Excellent work love it

I'm running the 1100KV version of this motor in my X-Ray, I personally prefer slower motors that can turn larger props. If nothing else, they are quieter lol.

I would suggest when you launch this plane to have someone else throw it at first, launch @ WOT and hive them throw it up on a 45 degree. You have the 'i don't have to worry about stall' card so you might as well use it.

Get the plane up in the air and trim it out before you attempt to hand launch it yourself. If you look at my spitfire maiden video it takes me quite a while to dial it in. Give it a good firm toss, the plane will want to torque roll a little at first but it will pull out of it rather quickly once you gain airspeed.

Ok mate thanks I'll make sure I follow them instructions.
Theres a possible little issue,when I lay the plane on its belly on a table it rolls onto its left wing (as im facing the plane), due to the fact that the belly is curved i suppose its got to roll one way but even when i lean the plane on its right wing it still rolls over onto the left wing.will this effect the flight ? its strange coz i think theres more weight on the right side coz thats where the larger reciever is and the little 2nd reciever is on the left side with the servo ( which i suppose weighs a bit). if i lay it on its belly on the carpet it doesnt seem to do it as much.

My plane also does the very same thing, just as long as you make sure there isn't anything obviously wrong. remember A nose heavy plane might be hard to control, but a tail heavy plane you don't have to worry about; that usally it ends in a crash.

Ok Im all set apart from the spinner,prop and charger which im waiting to be delivered.Oh I need the cf tubing too but 1 more thing about the centre of gravity,in the spit manual it says 70mm with a 11.1v lipo from leading edge of wing (I take it thats from the edge opposite the ailerons) but it doesnt say how many mm from the end of the wing or if u like from the fuselage ? or is it just 70mm from the leading edge and it doesnt matter about the distance from the end of wing or fuselage ?

Take the measurement from the LE as close as you can get to the fuselage.

Talking Maiden Video

Alright, here is my official maiden... (this was a replacement airframe and never flew with stock kit) after a few shakedown flights everything seems to be working great - besides a slight pitch-up at WOT as predicted by Aetc4Boom, it flies great. And fast enough for me.

Awesome job!!! Here are pics to help the WOT pitch up you mentioned. Just shim it between the fuselage and wing at the mount holes. (Pic is from my former P-51, but principle is the same).

Can I please ask, what does "WOT" stand for?

Turn the outer part of the mount around, you can the get it to sit back enough. I was worried about this problem as well which is why I chose the components I chose, so that they would fit right. Or you can turn the motor around, move the center shaft so it sticks out the front and use a collect type pop adapter either option should work ok. Don't forget to balance it, I would be interested to see where it balances as is and how much weight you need to add to the back to get i to balance at 60mm

Yeah, she is a rocket. I flew this right after my styro chuck glider project which is considerably more tame, ad I had never run it wide open like I did here, so it was a handful and a blast all in one.
