thanks guys, i should have said what plane it is. the plane is a modified GP extra 330L (wings lengthend 5 inches on both tips, so it brings the total wingspan to 110 inches. 18-20 pounds was the weight i was hoping for, the manufacturer claims an overall 18-25. the stock wing area is 1670 square inches. but with the added length its probably closer to 2000 square inches. (i don't know the math to figure that out [sm=bananahead.gif]). and also the stock wingloading is 26-30 ounces, that should be brought down with the increased wing area. i think im going to buy the ZDZ 80...9.5 horse power for that size of an engine is unbelievable.

thanks for the help guys,
James
