Put flights 5 and 6 on mine this weekend, original 19 lb Jet Central Rabbit, 23lb dry, 3.5" mains, 2.5" nose wheel on Dreamworks struts and it takes off in half of our 700 grass runway. You've got 4 more lbs of weight but 3 more lbs of thrust I would think your performance ought to be fairly close. You might want to double check your CG and make sure its not nose low when on the ground, also I take off with 1/2 flaps.
