If I put the .50 sx-h in a UCD 46, will I have to add weight in the nose?
No if you use the tower pipe, a true turn spinner,and non metal gear servos in the tail you should be good to go. Oh yea put the battery as far forward as possible. We are putting the CG @ 5 3/4".
That is the set up some of us are using here in San Antonio.
