RE: TF Contender
Hi Jim,
I have a Saito 72 in mine with the servos as per the plan. To balance I simply moved the battery pack to the rear of the position on the plan. Once you a familiar with the model you will probably decide on a slightly rearward position than that recommended. Mine performs to my liking with the CoG 5mm aft of the plan position.
For first flights balance as per plan.
Cheers,
Colin
