2.6" Screech, part II
« on: December 25, 2015, 10:17:43 PM »
So, madcow lets you order just the booster for the 2.6" kits.  lists as 38mm, but a quick email confirmed they'd do them in 54mm as well.

My love for my 38mm screech is the worst kept secret in the world....so here we go again :) 
The longer motor mount is pretty slick, as are the tiny CR's.   Love all if this.

I haven't decided if I'm going to install a kevlar harness, or just attach to the motor bulkhead.

I'm not sure how I want to change the paint...but I'd like to subtly indicate a difference in the boosters.  maybe a stripe on a fin or something...

that thing is going to scoooooooooooot! I would use kevlar strap, just to make flight prep easier. it just HAS to be longer than any motor you're going to put in there.

Patell suggested black.... I kind of like it...a lot.





I did some math.....  an L1040 in a 54/2800 can technically fit :)

well that looks fun! I would like something like that with electronics to fly single deploy or possibly cable cutter. I like the short nosecone.

MMT all glued in.   AP mated right up to the BT.   If I did this all again, I'd likely just skip the kevlar harness.   

Instead of adding epoxy inside the body, I put it on the top of the two CR's and shoved it in and let it run out to make the joint.  Would up making a mess, and nearly glued the aeropack to the BT.     

I took the cap off, cleaned up the epoxy with acetone,  then covered the aeropack in vaseline and and screwed it back on.    It seems to have done the trick,  but next time, I'm just putting the epoxy in the tube like i've always done before.

All three up.  :)   Proline 4500 will be used for fillets.

this thing is going to rip. curious to see if it has no spin like the 38mm one.

I usually spend a good bit of time setting fins.... I'm literally going crazy checking these to try and match the performance of the 38.
