jwatwood;
I spent some time flying the Ultimate last weekend. With the CG in the middle of the specified range, she is one great flying machine. I haven't found anything that she won't do. She makes me look like I know what I am doing.

But seriously, I don't think you can go wrong with the Ultimate. As you already know, she is great flier. Good luck and enjoy.


Here are my final specs:

YS FZ 63 engine
Stock tank (~ 9 Oz, ~ 9 mins at WOT)
2X Hitec HS 5245MGs(rudder, elevator)
2X Hitec HS 225MGs(ailerons)
1X Hitec HS 85MG(throttle)
Airtronics 92777Z micro receiver
700 MAh Airtronics battery pack
APC 12X7 prop (I will try a 13X6 next time out)
Tru-turn 2 1/4" jet style spinner

Dry weight: 5 1/4 lbs
Balanced in the middle of the specified range. (1 1/2 oz lead in tail)
Lateral balance came out perfect, no weights needed.

Mods:
Used Dave Brown engine mount and 6-32 hardware
Wing cabane strut lug holes were 1/8" off. I filled the holes and drilled new ones.

Replaced metric interplane strut crews with 4-40X1/2 hex cap crews and blindnuts
