RE: GP Ultimate Bipe.40 build
Insanemoondoggie,
I have built two GP Ultimates (still have #2) and also own a Magnum 52FS. I think you will be disappointed with the performance of a GP Ultimate with the Magnum.
I had a Saito 65 in my first Ultimate and the current one has an OS46FX which flies it very well. If you are going 4C I suggest you try and get hold of a 65 or 72.
BTW, can confirm one servo is OK.
Regards
Terry
