I can hang my up roar just fine using 425's. I have only used a high speed servo once and it is on the rudder of my edge. I think it is a Futaba core less. Man it was pricey $100 I think. can't afford that on a 40 size plane.
Sounds like you had a nice set up. least it was an arf and that does'nt hurt as bad when it goes in. I just got mine from Tower $119.95.
Maybe I overkilled the servos, but I had some past experience that changed my thinking on servos. I had a 1/4 Cap 232 setup for 3D throws, I used Hitec 605's. The plane always felt 'loose' and squirrly. Never would seem to hold trim. Then I noticed how the poor centering of the 605's was magnified by the long arms used for 3D throws. I installed Futaba 9202 coreless servos all around and BAM, what a difference.
There is nothing wrong with 425's or 605's. They are great servos for the price. I just think differently on high deflection surfaces now.
BTW: That 4735 is 90 oz/in and 0.15 sec on 4.8. You CAN and WILL notice a monster like that on rudder when it tries to fall over in a hover.
