RE: Ultrafly Ultimate
Well, as I said, I'm assuming that setup. He has a hacker motor (dno which one?) I'm sure that his using TP 1320 pack. He gets only 6 minutes of flight. I said that his using a huge motor (heavy) thats why he wanted to stay still light and used smaller pack.
Yep, I was wrong with the prop... it was something else...
Sorry for the wrong info. The plane isn't mine that's why I don't know a lot about it.
