Esky Eyas The impossible prop and take off!

Struggling to take off with the stock prop on this plane! I've seen this plane having a stock 3-bladed prop but mine came with a small 2-bladed one with just not enough push to get the plane in the air. When I put a 6x3 3-bladed prop on I could take off! Wingspan: 1100mm Length: 871mm Flying Weight: 755g I fly mine with a 3s 2200mAh battery and Spektrum NX10 TX.
