RE: Which is the best?
I would avoid the GP patty if you want to 3D, it flies well though just not a 3D monster. The H9 260 other than the gear sucking flies well and 3D's well but read through the thread on it for some first hand experience. The wildhare extra special basically is a 260 in disguise, look at the wing placement on the 300 and 300 sp. out of those three the wildhare will probably be the best.
I am currently flying a TOC yak 54 and with a DA 50 that thing is a monster...just food for thought
