Either that elevator is too smal or your CG is too far forward. Try it when your tank is a 1/4 full.

Hi!
Yep, I did use aileron too to try to flatten the wings (forgot to mention it earlier), but the stupid plane (that´s right, it´s plane - not the pilot

) keeps diving..... I used full up elevator (50 degrees) but doesn´t help - nose keep pointing the ground. Anyways, thanks for your replies - will try those when I´ll get back to the field.
