Hi starfire73 , I would also go with the larger 60 size planes. They are less twitchy, fly smoother, and look much more impressive in the air not to mention easier to see. As others have mentioned the 60 size doesn't need a longer field to take off or land than the 40 size. As far as engines my favorite for the 60 size planes is the Tower Hobbies 75. Mine have proven to be very reliable performers and have strong smooth power output. The price for this engine is also a bargain. Why buy 1 four stroke when you can have one TH 75s and $100.00 left over to put towards the plane?? [8D]
