The ultra micro icon a5 is a great park flyer/amphibious aircraft. I have flown in a large gym but the basketball goals were down and narrowly dodged the first 3 goals but hit the 4th one after 1 lap. Nothing broke from a half throttle crash into a 9 foot high basketball net.
it took a wing and nose first crash in to the ground very well and the only thing lost was a magnet for the canopy
but that is easily replaceable. It handles very nice in the air and on water, but in the water it tends to dip its left wing when going slow but recovers when the speed picks up.
Pros: easy to fly
takes a hit
AS3X
easy to repair
Cons: doesn't climb good
pricy for plane and extra battery
cant take much wind
In conclusion the ultra micro icon a5 is a great airplane even though its pricy I think it is well worth it from its exceptional handling to its amphibious capability.
