I don`t think its worth it, at least as it is right now.
With no dihedral you must use ailerons, and i don`t see any in the pic.
One moore thing is that the horisontal stab seems to be too small.
I think it`s too heavy also, but with the right gear you might be flying,... fast, maybe too fast..

It will fly. If you give it a dihedral and larger stab.
I don't think it is too heavy though. With all the electronics it will end up around 25g. It is not too heavy for 14" wingspan.
Finish it and prove that I am wrong.

You will need a 7mm motor or better.

Is the model your own design? As 'Jing says, with some mods to the tail & dihedral - give it a try If it doesn't fly well, you can still put the gear into your next plane - if you do like it and it flys well - you'll be addicted to micro models by then anyway!!!!
Let us know how you get on. Good Luck

ok hold on...Dihedral is the upward angle from horizontal of the wings or tailpane of a fixed-wing aircraft or the wing of a bird. Dihedral is also used in some types of kites such as box kites. The aerodynamic stabilising qualities of the dihedral were first described by Sir George Cayley in 1808-09. Downward angled wings have negative dihedral, or anhedral. Wings with local dihedral angles that change along the span are polyhedral.

The purpose of positive dihedral is to confer stability in the longitudinal (roll) axis. Most aircraft in the civilian or transport sector use dihedral for roll stability. The dihedral angle is usually greater on low-wing aircraft, compared to an otherwise similar high-wing aircraft.

Thanks for your help everyone.

I will try putting electronics in it. If it dosn't work i will put them in different plane.

Is this what you mean by dihedral?

yep, that's dihedral . Do you know what angle that is? You don't want too much or it'll get difficult to steer.
