I'm flying my Ultra Stick Lite with a G-26...and it is my favorite plane to fly right now! My receiver battery is in the tail as far back as it will go, and my servos are in the stock location under the wing. It is slightly nose heavy, but still a ball to fly. I would suggest getting a B&B muffler for the motor (or is it a Bennett), that really woke the motor up. I've also installed a smoke system (decided to figure things out on this plane before putting it on my Sukhoi). Here's my current setup:

Stock G-26 w/B & B smoke muffler
APC 17x6 Prop
Hitec 645 servos Rudder and Elevator (under the wing)
Hitec 625 servos on the Ailerons (no split flaps)
Hitec 425 throttle (under the wing)
Slimline Skywriter smoke pump w/16 ounce smoke tank
Stock 22 ounce H9 fuel tank with a gas stopper.

When I first started flying the plane I had a Saito 180 on the nose. The G-26 added about a pound to the overall weight of the plane. Plus, this Stick is a little heavier than normal because I played lawn dart with the thing when I was hovering and the thing ran out of fuel...the fuse broke into 6 or 7 pieces. The added epoxy and ply added some weight to the thing.

The plane doesn't even notice the extra weight of the G-26...in fact, with both tanks full, it will STILL hover!!! It barely pulls out of it, but I also have the extra weight of the smoke system in it. I'm very impressed with the overall performance of this motor. Please note we fly at 4400' altitude, which does choke the power down compared to sea level.

With the Saito 180, it would burn a 24 ounce tank of fuel in about 14 minutes. With the G-26, the 22 ounce tank lasts 45 minutes...I can fly all day for less than a buck!!!

Just my humble impressions.
