ORIGINAL: earlwb Unfortunately quite a few ARF and RTF planes sold by many companies and stores do not have spare parts either. One has to double check, if they expect to need spares before the purchase as they don't always advertise it. There are some stores that stock spares for some planes, but you have to check to see if they have spares before you buy. Sometimes they never get the spare parts in too.
That's where I think, earlwb that those who want to take a chance on purchasing planes from some of the volume internet houses that lack spares should expect to be able to repair these ARF's when they crash. Those who don't, then spend a little more on established vendors who do carry spares.
Otherwise, the ones who benefit are those who can repair, who receive these donor crash victims freely for their own use after repairs.
