I have been flying for a year now and I have built 5 different Hangar 9 ARF kits. I decided to buy an alpha 40 and put pontoons on it. I bought the plane and assembled it. I decided to take it to the flying field to get a few land flights on it before I install pontoons and attack the water. The first time I attempted a take-off the plane took a hard left about 10 feet off the ground and ended up hitting the ground. I repaired the plane and took off again with the same outcome. I repeated my actions one more time with the same outcome. I used new servos, I know what I am doing when I build these planes and I could not find anything wrong with any of my equipment. Now I have to buy a new muffler and carb. for my engine because of the last nose dive. Has anybody ever had this type of experience.
