Hey, Buzz!

Sorry to resurrect this thread from a year and a half ago, but here goes anyway.

My initial measurements (100% and 137% upscale) are as follows:


Booster length -- 3.00" --> 4.11" (will probably round to 4.00")

Main body tube -- 12.00" --> 16.44" (rounded to 16.5")

Nose cone 3.00" = Semroc BC-730 --> 4.11" = BC-1041P


I'll need to order a 137% fin set *without* the slots from Carl. (Were your fins 3/32" or 1/8" balsa?) And some HTC-10's, too.


I downloaded the plans for the Centuri T-Bird last night, but I noticed that its lower stages are only 3" long:

Anyway, here's my burning question: Since you put EM-710 mounts in your version, did you have to "gap" stage things internally? Inquiring minds want to know.


Thanks, as always, and cheers,
