Flew the Demon 98 yesterday on a CTI K1200WT. Gorgeous flight to 9753ft. Just kept coasting and coasting... love this rocket!
I was told that MMWP was the last launch until MWP. Rats. Must have been a special invite launch only. I am not special.
Dear CZ,
I have a problem. My boat tail coupler doesn't look like yours below. Yours is so big and long.

Instead mine can only be described as short and stubby, 1" or so (see below). Should I be worried? Will my rocket perform?

Is this really a problem? What would you recommend?

Is it glued in all ready? if not call Tim he can help out with short coupler.
Mine is close to yours, Tim. Maybe 4" total length. I was just gonna split the difference and put 2" in each side...

But if you install the CR where it should be, at the forward edge of the fin tabs; and since the CR is sized to fit the coupler and not the full width of the boat tail; it only makes since for the coupler to be inserted fully, otherwise you have a "floating CR."

How long was your coupler and motor mount to start with ?

it is designed for 2" both sides
Allll righty then... That's how I'll do it. Got the Aeropack on the mmt tonight. Tomorrow night, bridle. How far ahead of me are you, Tim?
Adrian (who is building at a blistering pace<for me> to be ready for the MWP XIV dragrace)
Adrian, if it is me (Tim) you are asking, I'm moving along quite nicely here.
I sent 4 cones to CTI. When I got them back, they slid right on the couplers. Well worth the $24.00 in shipping IMHO. They also included a coupon for $24.00 of CTI products from Mr Wildman. Now if I could just remember to take it with me to Tim's...
Adrian
Is that still an option? I've got a couple that work, but I'd rather them be better...
Yes I was. Wow, you're moving right along. I need to try building that fast... :eyeroll: Yeah, right...
Oh well. I think I'll get it done by MWP. Hopefully MWP XIV... :blush:
I forgot about ordering Stickershock... Darn. Might have to fly nekid...

-6 feet of Kevlar Strap for Y-harness to motor mount
Hey Cz,
Thanks for the build thread, looks great!
I'm building one for a Wildman CT drag race and one thing I wanted to check with you on is the 6 feet of kevlar strap noted...I had a 10' strap and cut it down to 6', but now it seems too short by about 2' of strap to match pic #2 of post #12.
Should it be 8'-10' of kevlar strap?
