I'm ready to start putting together my fifth .46 Ucando as well. I also have a .60 but haven't built that one yet. Number 1 was lost due to pilot error, radio failure in number 2, horizontal stabilizer broke off on number 3, and lost my fourth one yesterday in a fly away. I have been able to supply a few spare parts to others at the field, about 10 people have these at my club but I've by far had the most failures. I've been using Eclipse receivers but think I"m going to go back to a name brand like Futaba. I have a spare already I haven't built but may take some time off from the Ucando for a while. It is a great flying plane, though.
