Known issues

Some people have suggested that the ball link sockets can become brittle in cold weather.

Some people have had issues with the main gear stripping in normal use. This may be due to the gear mesh being slightly out; an aftermarket clutch block may help fix this. Align has reportedly quietly brought out a very slighly larger diameter gear, which may or may not be a better fit. The MicroHeli CNC delrin maingear replacement is reported to be no better than the standard Align one.

There are strong rumors that a gasser version of the 700 is under development.
