I plan on using only one servo for the elevator on this plane. I will be making two rods that are connected to each other using two collars. I have done this on my Dynaflite SE-5a and it works great. The servo I use is a high torque GWS S-03, it has 86oz of torque with a 4.8v battery. This also cuts down on the weight a little. After the plan is built I test my CG and if it in not correct I reposition my battery pack until I get it right. I never add any weight to the plan to get the CG unless there is no other way.

Thanks
