I have the U-Can-Do ARf. I have it powered w/ a Saito91. My prop is a 15x4W. My fuel is 15/16.

I don't have my wheel pants on. And I didn't mount my cowl. I was waiting to see if the Saito 91 was going to have enough power.

I have 4 flights on it and it flys a little below 1/2 throttle and hovers a little bit above half throttle. Pulling out from a hover is like a freight train, it will pull out but verticle performance is nothing spectular.

So my questions are.
What motor, prop, and fuel combo are you using? How is your vertical pull out of a hover?

I ordered me a 14x4W prop from my LHS but it won't be here until next week. I am hoping that will help my verticle performance.

I have followed all the UCD threads and looks like everybody with the recommend engine range is going through this same situation.

I am probably going to swap to a bigger motor. So I can make the most out of this plane. But I don't know which motor to go to.

I won't spend $270 for a Saito 100 because I don't think the Saito 91 and 100 really differ that much in power. Anyway how much can .01 of a cubic inch really be. I am thinking of going to a 91 2 stroke.
