RE: F4E electric vs trainger
Ducted fans don't glide well; they need power at all times; and they are prone to tip stalls when the speed bleeds off too much. If you have an instructor close by with the use of a buddy box will help you get up and down much more 'safely'. Otherwise, if you take it up alone make sure you do a nice level t/o (no immediate turns), get to ' 3 mistake' altitude before doing anything radical. When you get to altitude, trim it as best you can, get used to flying in a racetrack so more is learned about the airplane's characteristics (3/4 throttle), and when you are getting comfortable after 4 or 5 flights, experiment to find the plane's stall characteristics (at '3 mistake' altitude). The '3 mistake' altitude should give you enough time to get over initial panic during an unusual attide and get the plane into a good flight regime.
