Sharkey - I looked at the specs of the Saito 100. Realize that according to Horizon website, the Saito 100 puts out 1.8 HP on 30% Nitro Heli fuel. I don't know about you, but I don't want to spend that kind of money on fuel for a Saito 100! I realize that it doesn't need it, but why are they rating it using 30% heli fuel What is the HP rating with 5% or 10% (more commonly used)?
I believe that the Saito 100 will hover the Ecstasy, though I wouldn't want it (IMO). I run the ST90 with a Mac Header and pipe. The ST90 is suppose to put out 2.5 HP (plus with the header & pipe I'm sure a little more). I am running a 15X4W APC prop on mine and it hovers at about 1/4 throttle. Yeah the Saito 100 would hover it, and I pretty sure that it would pull it out of a hover, though with what authority? I don't know. I have one customer that was talking about putting a Saito 100 on his at one time, though I do not know if he is going to follow through or not. I talked with him the other night, and he has the wings completed and is starting the fuse right now. I see guys post here on this forum of them loving the U-Can Do 3D with a Saito 90 & 100 and by the sounds of some of their feedback, it weighs about the same as the Ecstasy and the Ecstasy has more wing area. What it really boils down to is what you want out of the aircraft. I personally wouldn't have the Saito 100 on my Ecstasy, I would rather have the 120, but that is me and I can not speak for you. Yes I firmly believe that the Saito 100 would hover the Ecstasy, to answer your question directly (again <GRIN>)
