Okay, here is where I am at.
I have it built and made a change, I went from dual deploy to HED. Loosing that 20" made a difference over all. Nothing protruding on the outside. My one obstacle was the chute and cord with having enough room (It was very very tight using Spherachutes 72") so some sacrifice had to be made with downsizing the size of the chute. I am using Spherachutes 45" Heavy Duty with some nice thick cords on it. Now that there is room and not squeezing it together I will do the EJ from the top of the cone down.
I have this weighing in at 4lbs 5oz w/o motor. I put in my AT 5120 case and I am at 7lbs 13oz. I used this case as a reference as I do not have the correct case. I want to use Cesaroni M3700 with the AT tail cone. RS projects this to be well over my goal at 22,300' and Mach 2.62. I expect this to be around 16.5lbs on the pad. Just hope it goes straight off the pad. My future guess is 21500' and just past Mach2.
Now I have been told the AT M1850 would do it but it falls sort on the Mach end of it at 1.96 for some of you who may comment on a motor.
The wait begins for Airfest this year to launch this.
