"I own three planes from dynam/nitroplanes the Sbach 342, pby seaplane and a super cub I purchased for a friend to learn on. Mistake #1 getting 3 before even flying the first one. So following that mistake I ran into straight trouble with all the models. None of the proper hardware, no helpful instructions you'll have to web search for chats or look up you tube videos, to get real instructons from people who have already learden about cheap products. To many defective parts as well. I also get the feeling the support system is a fraud.
They'll try and make you pay for their mistakes."
