I'd like to build a RC-controlled boosted glider rocket. I have looked at a bunch of the beautiful Dynasoar Rocketry models but would like to try to scratch build something but have some questions. Be gentle, new to this...
CP-CG: Where do you want CG in the glider for gliding phase post launch? I understand that just like most rockets, it helps to have CG as far in front of CP as possible during launch. However, it seems like you want CG to be just a little in front of CP when it is gliding. Is there a guideline for this? Stuff I have read for RC planes etc... talks about complex positioning of CG in relation to wings etc... Can this be simplified to a CG-CP relationship?
Manufacturing Materials: I know that most of the Dynasoar models use foam board for wings. I would like to make a slightly smaller model that launched on D or E engines. Can I build with 2mm basswood fins or is it really much easier to construct with foam wings?
RC Controls: I am assuming I would put two independent pitch controls on either of the "wings" that would allow positive pitch (i.e., range from flat to upwards pitch). Basically it seems that you pitch the glider upwards to get it gliding once it starts its decent and then can steer things by letting up on either of the pitch controls. Is this the simplest best control setup to start with?
Model: I am still trying to select a model to build. I assume that bigger wings are easier for the glider part. Would a Boeing Bomarc be a good model? I have one of those I built already and could maybe add the RC parts and flaps to wings or tail (although would need to remove some nose weight). I would like to make an X-15 but that has smaller wings. I also would like to make a Lockheed A-12 which would be another option or maybe some other supersonic jet.
Anyway, any advice is appreciated - sorry about the long set of questions.
