If I were you I would get some extra engine mounts, CF strut tubes, extra nylon rotor screws and maybe a main gear. Oh, if you felt like it I would get a vertical riser too. There is a weak, thin point on there that cracks very easily. It is easily repaired with epoxy though. I have an extra motor or two also. Motors take quite a beating as with a bad landing they are the first things to hit. You may consider adding those to your list. That is, unless you want to wait forever for new parts to get to you. I learned this early on.
Pretty much everything plastic is subject to breakage when learning to land. The only thing that is safe, usually, is the board itself. But if you slide into a landing instead of dropping into one the flyer can flip over hurting the vertical board. The plastic canopy helps protect this. After talking with Mike at Spectrolutions he said that he does not fly the canopy as he feels it could interfere with the Ti sensors. I made up a CF flat stock roll cage for my board. It works much, much better than the canopy and does not interfere with the Ti operation. Email me if you have any further questions.
