Yes, it can work. Does your wing have a symmetrical airfoil? Your model could be configured like some of the Plank type flying wings from Radical RC.

You might also take a look at the RAZZOR 400 from K&A Models for one approach. It has a fixed horizontal stab and uses elevons for pitch control. Also notable is the tractor powerplant installation.

There is also the Spinsation from Morris Hobbies that flew very well with a thick symmetrical airfoil.

thanx for the info!

I get the picture now of what you actually can do if u just let your imagination flow!

I see that the black and yellow and red plane's elevators and rudder is connected together? How can that then work?

Elevons. The vertical stabs on the Quick Wing are fixed surfaces, not rudders.

Most computer radios have an elevon mix as one of the program features. For radios without that capability, there are add-on mixers available.

Though not a wing in a technical sense, you could always build something along the lines of the Sig Wonder. That model uses a standard control arrangement.

it's harder if your plank configured as pusher

I used standard 48" mwcores wing but built sweepless
