RE: tiger 2 CG
Uffda...I just finished up my Tiger 2 ARF...yep...there were some problems. I had to drill out the wheels to fit the axles. The main gear point toward the back instead of the front...perhaps that's correct because I haven't seen a pic of the Tiger 2 ARF. I also needed to drill out the holes for the main gear.
I haven't balanced it yet. The factory really chose an interesting/dumb location for the servos...right under the wing bolt area. I figured there was no way I could screw in servos at that spot so I moved the servos toward the middle.
I built/flew a Sky Tiger with a Fox 50 in the early 90s...an outstanding bird back then.
I hope to get it airborne this weekend if it doesn't snow up here in central MN.
