I practice alot with G2 and like RC setup is everything.
Do this. Use the extra 330 on add ons 3. It flys most like my 35% planes. Now increase the visual scale a bunch. I like 6-8 times and this slows the plane down a bit too. Now trim the plane out with your computer radio and use all your mixes especialy rudder to elevator to get it fling nice and straight.
Now this is the key to practicing sequences,this is why the plane is so big,is to turn on" look at ground" on views. Now you can see the ground the whole time and the plane is big enough to see on a fair upline. Just showed this to some friends that didnt like G2 for practice because you would lose orientaiton. They love it now. See if this helps
