From my experience,
at least 90% of all crashes are pilot error as the root cause- whether it be improper setup, poor construction, inattention to detail, flying beyond one's abilities, improper/poor equipment & maintenance... the list goes on!
Just make sure you check your CG, make sure the control surfaces are correct, engine is happy, batteries are charged- and most importantly make sure the pilot is relaxed!
If you have checked everything on the plane, and are confident, you will do fine! Keep it high, keep it slow
