Thanks for all of the suggestions. It looks like I might try a combination of things that are suggested here. One thing I did consider was to weigh the original landing gear, and the new one that I added, and see exacly how much I have added in overall weight. Since the gear is not clear out front, but close to the CG, my thought was the it might not affect it too much anyway. Lastly, I will check the weight of the sullivan tailwheel assembly that I used, and account for that while comparing the different weight between the landing gears. Since one went in front of the CG, and the other behind, I may be concerned over nothing, or at least just a small change in the CG. I am using the common OS46FX engine combination for the SE since it is a pretty common match up to the plane.

Thanks again for all of your suggestions.

BTW: JimTrainor, my next plane is the UCD46, but I will be using the Saito 72 for power. I hope that it will add some of the weight I might need to get a better balance.
