got mine almost done. Anyone use an Os 70 4 stroke? How does it balance? Where is the Bat and RX?

Rick,

With a TT .46 mine balanced without additional weight with the battery at the rear of the wing and the receiver at the front of the wing.

Mine has a O.S. .61 and I had to add considerable weight! Flies great still.

How does it fly with the tunder tiger 46?
I was first going to use a TT 46 but then changed my mind to an os 70 I just like the longer run times and you can always use some more power! But if I will run into a CG problem I might go back to the TT46, that is if you think it's enough power!

Rick,

It will fly very well with the .46. You will not get unlimited vertical, but, you will be able to do everything it was designed to do. I think the perfect engine would be the YS46.

servo
 

Anyone ever thought of putting the rudder servo in the bottom of the fuse by the tail using pull pull?

Rick,
With most engine that would mean you would have to add about 1/2 pound of lead at the nose to balance the thing, at least you would on either of mine.
