Yes , you can put the prop right on the motor shaft between the flat washers and nuts . Where the prop is located on that plane it is well protected and there is no need for a prop saver .

Okay cool thanks for all the help! Looks like i have no more questions for now, so im going to show you what i have done so far! Let me know how you like it.

(didn't tape any wires down, so thats why the ESC to Motor wires are hanging into the prop slot )

Looks GOOD! Don't forget to have the numbers/letters on the prop facing the FRONT of the plane . Also , what size batteries do you have and how many ?

When you say letters facing the front, then do you mean the letters should be facing the motor, or the servos? I have 2 800mah 11.1v gens ace 20c batteries.

Facing the motor , which will be mounted in FRONT of the prop slot .
You're probably going to have to put BOTH batteries up by the nose to get your CG right . The CG should be about 13-14 inches from the tip of the nose straight back down the center line , and don't forget to put in a little up elevator for reflex . Reflex is needed on a delta to slightly push the tail down , which causes the nose to be slightly up so it can "plane" on the air - much like the tips of water skiis needing to be slightly up above the water surface so the skiis can plane on the water .

Oh okay thanks. I have some 2200mah 11.1v batteries...would those work as well? Or too heavy? Thanks for the tip on putting in some reflex. How do i know when i have put in enough though? Also, where did you get that wood for mounting the motor? Im thinking of just getting that rather than buying a plastic mount.

The 2200mah 11.1v would probably be the best ones to use for this plane , just make sure your CG is about 13-14" straight back ( down the center line ) from the tip of the nose .
Start with about 1/4" up elevator , then trim as necessary on that first flight ( if there is someone experienced who can trim it for you , that might be good ).
The wood I used for mounting the motor is 4 popsicle sticks taped together , put into the motor mount , then I put a wood screw in the little hole ( drill a pilot hole first so the wood doesn't split ) , and then a little hot glue .

By thrown, smooth landing, CG position was found about 42% from TE. Is that becouse 2x dihedral?

Push or pull... Does it matter? Should fly either way right?

It doesn't matter if it's push or pull ( prop behind or in front of the motor ) , but it does matter that the prop is facing the right direction . Most prop blades have a side that curves out ( the side with the numbers/letters on it ) , and the other side that curves in . For the prop to be most efficient ( most thrust ) the " curved out " side needs to face in the direction you want the plane to travel .

Brain fart on my end. Was thinking the motor was turned around. Prop always faces front.

I decided to just get a Y cable and will finish the build tomorrow. Lets keep it tame for a bit. I did build an elevon model a while back and played with it till i toasted it.

Here is a pic

Will do a vid If i can get the wife to film it.
