Has anyone ever put the tail feather servos at the tail in a Burrito? I seen a post were Paul had them in the tail of a plane but it didnt look like a Burrito. The leads where ran down the carbon tube. I dont want to mess up the design, but I'm wondering if it will work out better with a 4 stroke that way.

Once again with feeling, why do you presume a 4-stroke will be heavier than a 2-stroke? From the Horizon and Tower webistes:

Saito 72 16.6 ounces with muff
OS 46FX 16.7 ounces with muff

Now, the OS 70 is a piece of lead at 20.6 ounces, but I've never seen one of these on a profile.

YS .63 is 17.8 oz, which is what I plan to use. More importantly I guess is that I prefer the shorter control linkage. I guess maybe I should have asked if anyone had mounted the servos in the back and had a problem with the CG that didnt require weight to fix.

I can tell you that I had trouble getting the CG back far enough on my YS powered Burrito. I put in a 2000mah pack as far back in the wing as I could and still had to add an ounce in the tail to get it to balance where I wanted it. That is with an APC prop, a Dubro aluminum spinner nut and a thin Higley brass jam nut. I can replace the APC with wood and trade the spinner nut and lock nut for a standard nut and it is about right without the extra weight in the tail. The bad part is starting by hand since there isn't any spinner for my starter with that setup.
I have another Burrito kit that will either go E-power or it will go light with a Webra50 and some lightening work here and there.
I think both tail servos mounted in the tail may be too much back there to balance even with YS 63.
Later,,,Matt
