If you are worried about going from a trike gear trainer to a tail-dragger second plane, consider converting your trainer to a taildragger before moving up to your second plane. You will find that the trainer you are so used to takes off and lands totally different - much better (especially on grass) but more of a handful if you don't stay on top of it. You will also find that your trainer flys faster since you no longer have that nose wheel to add all that drag in the air. Of course, this means your landings will be faster as well. Your trainer will still fly and land slow like it used to, but it won't slow down as quickly as before. This simple modification will allow you to take another step closer to the aerobatic type plane you are wanting as well as get more out of your trainer. Not to mention, trainers look a lot better after the conversion as well!
