These are very handy and work well. They extend telescopically so they are compact enough to fly with if you ever want to do that.
The only problem with this option is that Zenith suggest you drill through your front strut (see photo) to insert the tow bar.
Check out the linked ‘Skytek Towbar Attachment Bracket’ for a cheap and easy to install option that does not need you to drill through the gear leg. I have this on my 750 and it’s brilliant. It took me about 5 minutes to install as a retro-fit.
