about 2.5 years ago a flying buddy of mine bought 3 nitroplane models over a several month period until he learned his lesson. one in particular was a delta wing model(do not remember the name of it) that had these bolt on wings to the sides of the fuse. he ask me to come by his house to help him with it. the instruction manuel was worthless.on one wing panel the wing root was so far out of square that it would not come close to seating up against the fuse side. the covering on the model was coming loose and sagging everywhere. i told him he should send it back. for 2 weeks he called and e-mailed them every day but they would not give him the time of day. he decided to fix it and spent quite of bit of time repairing the one wing panel. on the day of the first flights everthing went without a hitch until the 3rd flight when the engine firewall came loose sending the model into a death spiral. i had told him to epoxy the firewall inside the fuel compartment but he got in a hurry and he forgot. another nitromodel plane he had the wing snapped around two ribs out from the wing root. the very soft wood spar just snapped. .all the negative posts i have read about them , you would think they would try and get their act together. they have to know about their reputation..sad
