There's alot of people cussing the Eclipse and Prism radios due to the lack of decent dual elevator functionality. The reason I suggested the 8103 is because I've used them for years and KNOW that they would provide adequate functionality for a plane like the Katana (and nearly anything else)...plus they're super easy to program...not quite as easy as the 10x but pretty easy.

The reason I used the S9402s is because I had them sitting on the shelf. They're among the best non-digital servos I've seen. I would have used the HS5925s all the way around otherwise. Another reason is that I wanted to give the HS5925s a good test before flying another new plane I have which has (4) HS5925 and (4) HS5945...and two HS225 for throttle and choke. So far the servos seem to be solid. I reprogrammed them using a borrowed programmer so I know the firmware loads are current.

If you could borrow a Hitec programmer you'd be set. If you can't, rather than buying the Hitec programmer, you might be better off using some of the less-expensive JR digital servos and a 'matchbox'. This would enable you to fine-tune the centers AND the endpoints. The drawback here is the added weight, complexity and expense of the matchbox.

Where can you get the S9402 for $79 NIB?
