Whoever mentioned earlier about need strong wrists was right. Lots of screws. Lol. Glad I have an electric screw driver or is still be on step 2. I'm still building. I have the diff installed, vert motor mount, top deck and the front arms on. If you build this kit and used the vert motormount, you have to install the belts in the opposite order than the instructions. Noticed it too late and had to tear some of it down to redo. Also I kept the stock top deck and just dremelled a bit of it to work with vert mount. Looks to be top quality kit. Best instruction manual that I've ever seen. Will work on it more tonight and hopefully finish it up tomorrow so I can practice Sunday. Looking good so far.
