About Half an inch or so. I think the fin tabs printed out like that because I originally was going to use a 75mm motor only and then when I made the change to the 54 with 4 29 I assumed it would automatically change the height but I guess it didn't. Guess I will just have to build another with a 75mm mount

I guess I could do that but I would rather just cut some new fins because I would have to fiberglass the whole fin to do that so the balsa that goes over the core isn't lopsided.

1/4" clips. The rocket is 10.5" tall and will weigh 14-15lbs so the 1515 buttons are suitable for this rocket.

I always loved the Nike Smoke also so I built the 5.5 in for my wife, I did same combo center 54 with 4 29s. I always used the K-695 for the center then did several different combos of 2 airstarts, toughest part building mine was the scratch-built nosecone 
did a wooden form then foamed, spun on a lathe to shape then fibreglassed it, got 7000 ft out of 5 flights then on a single motor flight (K 600 something Aerotech-demo motor) chute didn't open at all and watched the nosecone do a 12 ft bounce on the playa and destroy itself. nose has been replaced and the 1 fin that popped loose has been repaired. they are great fliers look forward to pics :wink:

Thanks. It sound like a lot of people have built it in this motor combo. Can wait to fly it. My nosecone will be bought from somewhere.

i'm getting a telemetrum that I will use or tracking and deployment as well as another eggtimer for redundancy and airstarting. I plan on just launching it on a K540DM at LDRS 34.

Nice work! The Nike is a wonderful prototype and the fins are so characteristic that they beg to be modeled faithfully.
The video is Composite Nike Fins and I used a variation of this technique on my Aerobee fins as well.

Ok a little update from the past week. I ordered my first harness from Onebadhawk recovery and Teddy was great to work with. I didn't know what size i should get and he explained the advantages of the different options he has. I ended up going with a 15' 1' 3 loop tubular nylon harness in military green! Im definitely going back to Teddy for the rest of my harness needs. I highly recommend him for any Harness you may need. Thanks again Teddy

Alrighty. Im trying to get the motor mount assembled today. I marked an 1/8" off of the aft end of each motor tube. The clips are .5" tall so an 1/8" exposed of the motor tube works out about perfectly for both the 29mm an 54mm tubes. I aligned the aft ring and applied for drops of CA to hold it in place and will apply an epoxy fillet once the Ca dries. Here is the shock cord I Ordered from Teddy. I have to get another one for the payload bay and I will be set.
