I have had several cmp planes and the one concern that seems to be common to all flyers of arf's is the quality of hardware. I have used some that is supplied and on others I have replaced them with more heavy duty harware saving one's supplied for smaller 40 size plane's. It seems that most flyer's in the 72" size do not use the hardware supplied. would be nice to know if this harware is stong enough for advanced flying or not. if it is not why supply it.
