Buzzbipe RC 010

Sure Mauricio the engine should be offset. The point is though that even if I throw the plane with the engine NOT running i.e. the swirling airflow blown by the prop NOT pushing the tail to the right, the plane flips over...meaning it is unstable because the moments of aerodynamic forces do not balance the moment of the weight in the CG because this is located too high up..

Otherwise all settings i.e. angles of attack on both wings, longitudinal position of CG etc are as per the building instructions. As FMK models - the seller of this plane- advised some posts higher up the plane was originally designed for heavier servos,battery and receiver. The light gear I use today does not bring the CG down low enough. I need to bring it down by placing the battery below the fuselage..I could as well add balancing weight on the front floor of the fuselage but I do not want to compromise the overall light weight because I want a fast plane..
