seiko, 1800 oz torque works good.

The seiko is a nice servo but not for a 33%. On the egde I would go with one Hitec 5955 I've used this setup on two 35% planes with out a problem and I have plenty of rudder authority.

Yeah the Seiko is great for a 40% plane. I used to run two HS 5925's on my 33%. I stripped them in about 40 flights and went to JR 8611A's. If you want to go Hitec then the 5955 or 5945 would be the way to go. Setting up your servos correctly so they dont fight each other is also important. A couple of servos fighting each other can drain your batteries very quickly.

5955. Or you can go with the 5745's if you need to save a little.

I run a single hitec 5955 tg on the rudder of my 35% cap. 45 degrees each way and enough power to knife edge loop.

you might want to use a bellcrank to take all the pressure off the single output shaft. 2 5955's would be a little much but that is what I would do, with a bellcrank.

seiko? are you crazy?

Thanks for the input guys, in the end I've ordered 5945's two of them is in the neighborhood of 300oz, that should do it.

It depends on who you talk to.
QQ recommends at least 500 ounces of torque for his 102" Yak. for example.
IMO, it is heavily dependant on weight. I would not trust a single 5955 on anything more than around 25 pounds dry weight.
I will be going with a single 5955 on my QQ 102", though, since it will be in the 23 pound range.
