Hey guys, I'm new here, a rooki too.

Bought a Art-tech Cessna 182, built it properly, meaning almost everyting( also motor) was already installed.
I lanced the plane by hand several times ( on a high grass field), trottle 100% open but the plane goes down on about 5 meters.
What am I doing wrong? Somebody can advise me?
A would apreciate this.
