New Design; Lil' Star Smasher
13mm Design Challenge ... At least for me. 
Here is an 13mm design using an ST-1380 main body tube that seems to fly on three of the four 13mm motor choices. Most 13mm designs will usually fly on only two of the four motors with acceptable Dv's. I do not know of an 13mm design, using an parachute recovery, that uses all four ( 1/4A3T-3, 1/2A3T-2, A10T-3, A3T-4) motors with DV's below 20fps. his could be an design challenge worthy of spending some time on. All in all, the Lil' Star Smasher design should be an all around good flier.
Enjoy and Thanks Again, JP
