Hi Ecuyer7

I can't help getting the feeling that you are very new to this hobby as I read through your posts.
Please be aware that the ST50 is NOT a model for newbies. If you have never flown please get yourself a trainer model and join a local club to get help. If you are a newbie you wil stand little or no chance of getting the ST50 to stay flying long enough to get the feel of it before it crashes.
