opjose, Well I got to maiden my Ultimate yesterday, Thurs. I met up with a good friend of mine that is also my instructor. He took it off first and was very surprised at how docile it was. I ended up putting my 40 la on it with a 10x6 prop. I will use this engine till I get used to flying it. Then after refueling I got to fly,with buddy box even though I am trusted, I wanted the extra security just incase. wow it flew just great. It was a little slow on the rolls and of course verticals were hendered by under power BUT it was a great time none the less!!!! It turned out that I wanted to keep refueling and flying over and over. But due to tx battery I had to give it up after 6 flights. What a shame...lol.
Now for the interesting part. I have now added longer servo arm on the ailerons and taped the joint between them and the wing. I have also added end point on the Tx but am still only at 3/8" movement. Since you have gotten 3/4" you must have some seriously long control horn and the hook up way down low...lol. Maybe one of these days but not to soon for me. Also I suspect that when I get around to adding the 46 things will pick up speed. aka roll rate speeds.
I'll keep you posted, thanks for any and all info to improve on a great little bird!!
