RE: Newbie here
Can't speak to the walkera as I have not owned one but I would tell you to go to the local hobby store and see what helis they carry parts for. 3 things in life that are certain, death, taxes, and crashes. If you have to wait for weeks to get parts then you will wish you had purchased something else. I know where I live nobody in the state carries walkera so that is out as far asn I am concerned.
Have you looked at the E-Flite Blade CX3 or cx2? I don't think I have ever seen a hobby that didn't carry parts for e-flight and it is a proven company and a great bird.
