e-flight Micro Yak 54 Jitters
 

Guys

I purchased an e-flight micro Yak 54 but it is extremely jittery in flight. I can't seem to figure out the issue. It appears that it may be prop wash over the control surfaces. I tried stiffening the hinges on the rudder and elevator but it only helped some.

I purchased this with the intent to try and learn 3-D flying but its very hard when the plane is jumping all over the place when I put power to it. Is this normal? Could it be one of the servos?

Note: I also replaced the receiver thinking it was noisy causing the servos to bounce.
