extra 300 arf??
Shouldn't be a problem. I went from my ultra stick to an extra. The only real difference is landing. You have to set it up and constantly decend, you can't float around like with a stick. Sometimes you need to add power. It's all about reading the plane, you need to watch how it is behaving. If you have to keep adding up elevator to keep a certain rate of decent, you have to know to add power. It's not very hard to do, you just have to remember to do it the first few times, then it will become an instinct. Just keep the control throw small for the first couple of flights, because the larger control surfaces make it more touchy. If you can fly a t-34 it you should be alright.
