About to get a bak-rak for stowing the paramotor behind the car.... Problem is no towbar fitted yet.... Do I need a special type of towbar to mount the bak-rak, or will a standard swan-neck do? Also if any of you out there are using bak-raks or similar i wouldn't mind seeing some pics of your intallations. Any points to watch out for? Any additional tie down points needed? Do you cover the paramotor with tarpaulin or similar when on the road? Are there any problems with 'drag' when drivin
