1/2A scale is indeed a lot of fun. It surely has the highest fun factor to time involved of any of the CL scale events. I think that those who participated in the Tucson Multi-Engine 1/2A Profile Scale events will attest to that. Also, the St. Louis club has had several contests for 1/2A scale that have been well supported.
I do not want to rain on this party, but was wondering if there was some special allowance to allow the rocket motor on the model SR-71. If this was a sanctioned AMA scale contest, then the AMA Control Line Scale rule book will apply. Paragraph 4.6 Pyrotechnics "Scale operations involving pyrotechnics (including, but not limited to rockets, explosive bombs dropped from models, smoke bombs, all explosive gases and any ground mounted device launching a projectile) are not permitted in Scale competition."
I think it is not a good rule. I can understand the need to have various restrictions on "rocket" type propulsion for CL models, but there is a wide array of rocket powered airplanes that would be interesting subjects (and practical and safe) if rocket motors were allowed in CL Scale. Several of the X-Series of test aircraft and the Messerschmitt Me 163 would be on that list.

Now that’s an example of the merits of decades flying speed.
You will notice that not only did Paul not screw himself into the ground keeping up with his plane but that he was still standing and not collapsing in a dizzy spell afterward.
Congratulations old chum!

Paul G. is great at this. I remember a 1/2A Team Racer that had every thing enclosed. D>K
