Bought a model called the tiger sport 40L (thunder tiger) about a week ago. After building it checked the CG and the model was WAY tail heavy. When I mean way I mean that the tail rests on the ground and the nose wheel up in the air when it is sitting on the floor. I built the model according to the instruction manual so i dont know what it could be. I have an OS 40la installed.
To reach the proper cg I reckon that i would have to put at least 8 or so lbs of nose weight to the front of the model. Is this normal?This is my seccond plane and I have not had this problem before.
Both the receiver and the battery are as close as they could be to the fuel tank.
Any suggestions woul be great
Thanks for your help
