I don't know whether it's the plane that is causing the problems, my lack of flying experience, or what.

I had flown a Cosmic Flyer a long time ago, almost a year. Figured I'd get back into planes since I've already got quite a few cars around. So I bought the Decathlon (electric version I might add)

I have no problems taking off, but like a few seconds after I take off it will just dive to the right and crash. When I flew before never had that problem. When it starts to lean towards the right, I will try and correct it but it never responds, so it's an unrecoverable dive. I just have to hope it crashes into something soft. Any suggestions on what to look for?
