I have a World Models Nemesis and a Hangar 9 Twist 150 3D that needs completed. I am wondering what servos to go with......... I am looking at the JR DS821 digitals / Hitec HS-635HB / Hitec HS-645MG Or, if you have a different suggestion, let me know. The JR and the 635 are similar in specs with the difference being digital, and karbonite vs. nylon. The 645's may be way to much performance wise for these planes. Let me know what you think.

Thanks
