In fact while it flys in the sky the dihedral would be around 3 degrees

That for increased launch height? What kind of boom did you use? Looks aluminium...

Very nice looking plane, construction looks flawless. The total weight and the wing loading are definitely on the heavy side though.

Looks like the BlueArrows ANGELīs Bigbrother. COOL...

Is it only rudder, or aileron as well? Reason for asking is that I have a wing with 3 degrees dihedral, and wonder if I will be able to control the glider with only rudder.
( have not bothered to finish the DLG yet, because of this, so curious how your glider performes).

EDIT: Ops just read that you have aileron... Ever tried rudder-only turns?

Follow my drift?...
Nice looking model. What, if anything, did you use to reinforce the wing spars in order to take the cf loads? And what sort of launch heights are you getting?

For rudder only your dehedral should be at least 10 to 12 degrees both sides.
For aileron i would suggest 5 to 7 degrees to have maximum control in thermals.
With only 3 degrees you will probably loose more hight every turn you make then the loss you would have(if there realey is loss) with more degrees dehedral wings during launch. 3 degrees wings won't let you control the plane by rudder only.

Looks very clean for sure. Could stand to loose some weight I think as well. Looking @ the picture of your rudder and vertical stab, you might be able to sand them down a bit.

Ooch.... Just what I feared. And that why the wing has not got a fuselage yet...

Thanks for the reply Alex,
