Fly -

Well, in setting mine up I did indeed pour through all those UCD threads Here's some info I posted in one of the whopper threads. This is what I decided on after averaging all the opinions and tossing in a little personal preference. Oh, and I was also considering the YS .91 and Saito 100. After seeing a few ounces difference in the specs online, I actually had a YS .91 AC and Saito 100 here on my bench and the YS was EIGHT ounces heavier than the Saito. Weighed on our company's postal scale. I was leaning to Saito from previous experience but this confirmed the decision.

Here's my model's info:

Engine: Saito 100 - mounted at 90 degrees to avoid inverted engine issues, remote glow starter, and on-board glow starters.
Prop: APC 15x6
Spinner: factory and still has to be cut for APC (but included in weighing)
Pushrods: upgraded to 4-40. Pull-Pull installed on rudder. Rudder servo installed in bottom of fuse near elevator servos.
Servo Arms: Dubro Supers
Servos: Fut 3003 on throttle, Hitech 425s on ailerons & elevators, Hitech 605 on rudder
Servo horns: Dubro heavy duty - 2 on rudder for pull-pull
Tail wheel: Sullivan with custom linkage
Covering: factory with some added checkerboard and silver
Canopy: painted inside with Pactra Silver and canopy is attached with small silver screws. Small ply blocks installed inside fuse for canopy screws.
Fuel system: 3-line - used fuel dot
Receiver: Hitech 8 with GP charge jack/switch in side of fuse
Battery: whoppin' 1700 Nicad (heavy 6 oz)

And the final weigh-in - including spinner although it's not yet cut and not mounted in the photo - was exactly 7.5 lbs on our company postal scale.

After all the reading, I was certain weight was needed in the tail for the Saito 100, but it balanced on the money at about 5.5 inches. (update)I mounted the battery a little further back and put CG at 6+ inches.
