Asanders,
Could you tell me the weight of your plane? I'm also using the 160 for power with an 18 X 8 prop and my plane weighs in at 16lbs. Honestly, I have been disappointed in the performance. I expected the thing to be a rocket with the 160 but it flies very scale like. I'm not sure if this performance is typical with the 160 or if I'm doing something wrong. Thanks in advance for any help.
