RE: Servo Recommendation
Brian
The 5600 digitals would be an awesome application for your model.
Yes, Hitec Service can and will reprogram the servo to meet your needs. There are also dealers/Hobby Shops that offer this service as well.
Programming the servos as you've mentioned is an excellent alternative to accommodate the models dual elevator servo needs with your Eclipse TX.
Be sure and utilize HD quality extension and wye. Minimal connector count (in other ONE extension to the rear or a long wye extension) and 6.0V power is preferred.
