I'm a "size matters" kinda guy.  Thats why I was asking about the 60 vs the II.  I cannot really call this my second bird as I have actually built and flown the GP PT60 twice now.  12 years between A/C.  What I am pondering I guess is my second airframe.  I would be ready to fly my latest incarnation of the  PT60 neek week.  But I am going on vacation in a few days so that puts me off by a week or two.  I figure I will be ready to buy the next airframe and start the build around late Sept, early Oct.   I want to keep the engine size (cost) below 150.  100 if possible.  I have several choices that will fill the engine compartment of the Tiger 60 nicely.    The Tiger just looks like a good all around choice.
