Default Yet another GP Viper question

I am at the stage of balancing my GP Viper, & was wondering if 3 inches is the correct CG ?

I have looked back through the old threads but cant seem to see anyone asking this so I'm guessing it's right.....

Tony.

3" works just fine but a bit forward would be better for sport flying. I would say between 2.5 and 3 would be a good range.
