Yes, TnT is correct. That video is great. The carbon gear would be nice, but I will save some money and try the 6061 T-6 aluminum gear first...More later. I don't know if I will get to try it before I leave for Florida on Jan. 3. I have not decided which plane to take to Florida. If I take the Extra I will have the answer soon. If not the test will have to wait until spring.
