I've been asked on numerous occasion to post the plans I have for a hang glider trike.
These plans are old and somewhat outdated and I make no guarantees for the airworthiness of the design - or accept any responsibility.
I did make this trike with a friend and it flew OK but we made some modifications.
If I recall there's no information on the engine mount or hang point keel cube.
I have plans for the keel cube we used somewhere and can post these as well if there's enough interest.
