Generally when I build a speed wing I extend the bottom skin foam so that it meets at the trailing edge where on FT plans only the top skin is. (hope that makes sense...
) Also the speed wing doesn't have the cambered FT tips. If the wings are cut already you can always iron the trailing edges and enclose the wing tips after. If you re-enforce the spar you could taper the foam spar so that the wing has a more consistent airfoil as the wing tapers towards the wingtips, essentiall making the wing thinner towards the tips. All of those steps will help out aerodynamics a fair bit.Check out @nerdnic speedwing videos, lots of great ideas there.
Ok, that makes sense. However I already cut the wing out. I'll watch the vid, thanks!Generally when I build a speed wing I extend the bottom skin foam so that it meets at the trailing edge where on FT plans only the top skin is. (hope that makes sense...

Wing installed...
Came together nice to. All is square, straight and solid. I was gonna use the original servo locations but all I had for servo extensions was 9", so I might bring them a bit more inboard to the inside of the aileron to get the extra inches. I think I will do the tail servos installed up near the cockpit instead of right at the end of the tail. Two reasons for this, no extensions and will allow for a more nose heavy airframe. The build vid shows the guys putting a 2200 butted up against the front of the wing to get it to balance, which means the battery is shoved in between the wing and the firewall. I am thinking I would like a little more play room to dial it in

Yep, peel the inside paper on the top of leading edge instead of creasing to get smooth airfoil, iron the trailing edges and enclose the wing tip and it'll a big improvement.

Looking good!
And yes to the servo replacement, my stock Racer had the battery all the way forward to get good CG. Mind you I believe your running a 3536 motor and the extra weight of that will help keep the nose heavy.
Good to know!

And I'd prefer to add tail weight rather than nose weight to get the CG right!

All true, I am usually a fan of doing the servos in the tail but I think this way I can do a pull to positive for the elevator a little easier since the Hstab is sunk 3/4" below the top of the fuse, I can mount the servos back to back in the battery tray over top of the ESC, which should leave lots of room and access to the Rx. It all works in my head any way

I am starting to learn weight can be your friend if applied right. Weather is not always your friend but I always want to flyI don't like adding weight at all

For sure! But if I had to....
Yes, better for winding flying.

Got the tail feathers on
Aileron servos are installed as well.
This thing is starting to look pretty speedy so far, the leaned back Vstab/rudder give it a nice aerodynamic profile. @Sero does this ventral fin look similar to yours? I might leave out the dorsal fin, don't think this will go as fast as yours, and if I want it to I will build a serious Racer.
