I am kinda suprized at your weight bike, mine with Brison gasser came in at 12 lbs 4oz on the packing scale at work. With a 16oz tank I can fly 10 minutes and have about 4oz to spare. The engine gives me unlimited power and will pull it out of a torque roll. The palne flys great and really slows down for landing. The only draw back I have seen with this plane is the white covering !
The creek version might be made by laser/protech. I know the version I have (red and white) is made by China Models/Flair. Here is a link to the info page:
