If you are learning with a competent instructor with a buddy cord, there is no way he is going to let you crash. So with that in mind, get the best trainer out there and that is the best flying one with the lightest wing loading.

If you are learning by trial and error, have no instructor, or are not near others that can help, you are going to have to self learn and that will mean that your plane will more than likely meet the largest object that it can not avoid............ mother earth, probably more than a few times. If that is the case either get more ARF trainers, cheap ones or get something that will take the abuse and ask for more, for the self learned the aircore is like money in the bank
