I'm currently building a Bomarc based on a BT-60 tube. The ramjets are made from BT-55 balsa nose cones and do add some significant weight to the model. Here is my quandary........the ramjets are going to move the CG off the line of thrust. Should I be concerned that the rocket is going to arc over and lawndart? If that IS a concern, any suggestions as to how I get the CG back in line with the thrust (without adding excessive weight)?

Use uncentering rings which mount the motor tube off center.

Give a man a rocket and he will fly for a day; teach him to build and he will spend the rest of his days sanding...

So far has not been a problem on the NCR/Estes Bomarcs, even on the 3in version.

Be REALLY careful when trimming the rocket for different motors.
