Oberst, just saw your post, my computer has been down for a while.... I think your Saito 150 will fly the Z just fine, but you will probably need nose weight to balance out. My Z balanced perfect with the 30cc gas and battery and ignition up front in the cowl. Over all weight on mine is 11 3/4 lbs. Make sure you have plenty of clearance for the wheels in the pants, esp in the back. Your tailskid idea sounds good, I don't like the looks of the tail wheel anyhow. Good luck with your bird. Thanks for the pics, a couple of them I haven't seen before. Duane
