Did you balance your Venus upside down - if you did and it still needs the weight go get a dubro spinner nut - they come in 1 oz aluminum and a heavier brass filled aluminum 3 oz nut to hold your prop on and help to balance the plane.
Yes, I did balance it upside down and I need 5 1/4 oz for it to balance according to the manual. This is with my 1400mAh battery up in the compartment under the fuel tank.
With the Dubro spinner nut, can you still use a regular spinner on top?
thanks,
