Hi all, I gust completed my first northstar and am having trouble getting it to break free from the surface of the water. I followed the building instructions as close as any serious model builder could have. I did do some mods as far as the fuel tank being relocated to the c of g allowing servos to be installed in the nacelle for the throttle and elevator. I planed to use a os 46 that I have but cant get the darn thing running proper, so I installed a os 40 la gust to see if this is worth buying a new engine. I'm guessing the weight to be about 7-8 lbs, is this engine to small? Is there any thrust angle that may cause problem with breaking free from the water? any help would be greatly appreciated. Thanks, Bart (man)
