That Giles is the same as the Giles I fly from Phoenix Models. I ran a tower .46 on mine at first, but then decided to go with a tower .75 with a 13X4 prop. The plane has unlimited vertical now, but is still a very fast plane in my book. I would strongley suggest not to fly this till at least your 3rd plane. I tried to jump into this from a MKII trainer, and about totaled it out. Plane is fast, requires a good clip to land too. You can even read some of my previous posts about that same plane if you do a search. It is a really nice flying plane though, just a little difficult for a person just starting out. Put it away for now and get some kind of low wing trainer... I went with a four star and loved it...
