Available at aeroacemods.com are all sorts of upgrades, including wheels (it will ROG -- roll off ground) and night lights. I often use the night lights to fly in my backyard:I usually can climb about 40-50 feet high on a no-wind evening and have a seven minute flight with "throttle maintenance."
In the picture above I added floats to my Aero Ace. You need styrafoam, hobby knife, fine grit sandpaper, balsa, and waterproof glue -- and a hot glue gun to mount the floats. The secret is to make the floats as small as possible in every way, but length. Floats should be 70-75% the length of the plane. CG (Center of Gravity) is tricky, but a visit to the forums at rcuniverse.com or rcgroups.com will be very helpful. Keep playing with it until it flies stable. My plane is a bit rocky and nose heavy, but some adjustments should result in better flight.
