no but the landing gear setup is pretty bad mine has broken off twice and it riped the structure off the fuse both times, also make sure your balence is on the forward settings for the recommended balence range! and try to push the tank as high as you can in the fuse and makes sure the carb is even with your tank lines (as they come outta the tank)or else your engine wont run right because the feed for the motor from the tank wont be sufficient.
