25% Pilot RC Sbach
I have been looking at the 25% Sbach from pilot rc. Those were the ugliest planes I ever saw when I first saw them, but there is something about them that has grown on me. I want one with a DLE 30 on it. I was wondering about people's thoughts on that setup and what servos they are using. I see the manual calls for 150 oz/in and the closest thing to that is the Hitec 5645 but they are slow, slow. I currently fly 30% or 50cc plane and am wondering how they fly compared to them. Also if you have pics of this plane please post them. I want to move up to 100cc but am going to wait a few years on that because if I had one I couldn't replace it due to the price. And if I can't replace it then I can't go crazy with it. Thanks

Awesome kit. Carbon spinner and gear, aluminum wheels, good hardware.
Don't cheap on the servos its got big surfaces. I have the 50cc version with 7955's all around on 6.6v LiFE battery and a DLE 55. Flys awesome. 3D's well and with a bit forward CG will do very nice IMAC lines.

I also use 7955's on my 50cc EF Extra. But I think that would be way overkill on the 25%. There's just not a good servo I know of in the range I need that aren't slow like the 5645's are. Are the Specktrum servos any good I haven't looked at those. Also what Rx pack would be good is a 2300 A123 pack too much?

HS7985MG's are plenty for 50cc stuff (HS7955's are 333 oz/ins HS7985's are 185 oz/ins)and something with around 120 oz/ins should be fine in the 25%er. I am running 2300 A123s in all my gasser birds 20cc and up. Wouldn't go back to old technology nor am I the least bit interested in anything that requires the use of a regulator. I use redundant batteries and switches and a power spreader from servo city that I got for a bit less than 20 bucks. I like the idea of KISS-Keep It Simple Stupid.

RE: 25% Pilot RC Sbach
I agree with Andy's comment and also believe you will feel the difference between . 21 and .15 on the speed. I can absoutely feel the difference between .15 and .10 on a 3D ship. Been there done that. My newest foamy has .07 Hitec's on it and that made a noticeable difference over .11's.
When first learning to hover a friend suggested faster servos and I said hogwash. I could hold it sometimes for a good while but would invariably get into an ever increasing oscillation, usually side to side with the rudder, and wind up losing it and having to punch out. (Hence my favorite saying - In Thrust We Trust) I eventually tried the faster servos and have been able to hover for as long as I want ever since. If the servo is slow and you give an input, by the time the servo gets to where it is going the plane likely already needs some different input. That's where you get behind and you wind up thinking you are doing something wrong and you're not. At least that's the way it is for me.
