gregziemba, I have the Saito 100 on my DO and I used the mount that came with the plane. One of the socket head bolts that hold the mount to the firewall needs to be changed to a phillips head bolt so the carb doesn't hit the bolt head.

zoott, you can to look through this thread to get all the info you need about how to do all the mods to the plane. Unless you can land this plane softer than most every other person who's ever flown it and do that every single time you put it in the air, you HAVE to reinforce the landing gear mount or you'll tear it out sooner or later. There are some real good pictures of how to do this very easy mod earlier in the thread. You'll want to beef up the push rods, the 2-56 rods flex way to much and you will get flutter if you use them. I've used 4-40 rods and carbon fiber rods and they both worked very well. I've broke the CA hinges on all the control surfaces so I'd suggest upgrading to something better than the CA hinges (I use Robart hinge points but that's just my preference). As for the tail wheel, it's your choice. I'm on my second DO, on my first one I used the stock tail wheel system and I did break the rudder CA hinges but after I put Robarts in the rudder I had no more damage. On my second DO I thought the same as patnjimtucker and used a Sullivan tail wheel which works great but instead of breaking the rudder hinges I've broke the tail wheel mount right off the plane, the bad part is that the mount broke off along with about an inch of wood off the bottom of the fuse so it's a toss up but if I had it to do over I think I'd use the stock system and stronger hinges.
