I've been doing alot of research on this plane (not much much info around) and what I could find talks alot about how it has the bad yaw tendancy. Not knowing anything about seaplanes or this one in particular I think I'm going to go a little smaller to start. It's been mentioned elsewhere that the yaw may be related to too much motor, over-torqueing the pylon and twisting it too one side slightly. It's not proven but it seemed to haunt some of the guys that were using larger motors. The motor they use for reference on the plans is the OS 1.20 (surpass I believe) 4-stroker which wieghed around 30oz. I think I'm going to use the new Evo. 26GT2 on it. This way I get a good range of prop availability as it can only spin up to an 18" prop due to clearance, and it doesn't weight that much more.

Funny you mention it falls like a brick, I've seen a couple videos from this year that had the seamaster in them and one glided very nicely and the other, like a rock. lol Wonder if the incendence has alot to do with that? I have a 4* 60 that I build from a kit, it has a RCV .91CD on it and it does the same, the more you cut the power the faster it falls. Not sure if it's the motor as it weighs alittle more than other 90 size motors or the incedence, didn't pay attention to it when building. First build, was just happy it flew..

ST3000, that's Super Tiger isn't it? No comments from the peanut gallery, hehe I'm still learning..
