The trainer 40 from Thunder Tiger is one of the best and most stable aircraft available for the student R/C flyer and now the Mk2 version is available offering a number of benefits especially if space to carry it is limited.After a flying session, the plane can just as easily be disassembled, thus requiring a fraction of the room normally required for transportation and it is much less likely to suffer "hangar rash" while going from shop to field.
