RE: Second and 3rd plane.
I have a Big Stick 60 with a super tiger .90 and its the best match you can get. You just have to be careful with the super tiger tuning and flying as its not as forgiving a motor compared to something like that saito. I would still highly recommend an instructor maidening any plane for you at this point,but that your call. I still get too nervous to maiden most of my planes.
