But a 45 degree cut on just the ailerons or tail surfaces mean you get just that, 45 degrees of throw. The stock hinges allow as much throw as you want with no binding. My son and I both use 60 degrees of throw on all surfaces with 20% expo and both the Turmoil and especially the Reflection fly great with that setup. I have tried the tape setup, and by the time you cut all the surfaces at 45 to 60 degrees and apply the tape, you can have the Flatout hinges glued in and the carbon spar glued on the trailing edge. The Flatout hinges also work much free-er than the tape hinges and when you hit the ground, and you will if you fly low altitude 3D, they just pop off, limiting the damage. The Flatouts do fly much better if you keep the weight below 11.5 ounces, over 12 and they start getting sluggesh.
