Default RE: O.S. 70 4-stroke & U-Can-Do 40..

The UCD46 has a CG range from about 4.5" to 6.0". Mine balanced easily, with only movement of the battery, at 5 5/8" with the Saito 82. It flies nicely there. One of the easiest landing planes I have. I didn't need to add any weight to balance. Mine weighs 5 lbs 14 oz ready to fly less fuel.
Thanks,
Barry
