Ya, I figured.... Forgot the smiley....
Hey, at least I got it built less than one year after purchase...

This size and diameter appeals to me. Are any kits still available?

This is a bit of a tricky build, but as usual, CJ does an excellent job describing the tricky parts. My 4" V-2 has seven flights on it since I finished it in Feb. of 2017. First flight was on a K456 Dark Matter, which really kicked it to 7262 ft. Several research motors later, I got into a drag race with the Wildman himself and won!
Was also in the mass launch at Alamagordo, NM for NSL in 2017. Mine was last to launch, with another K456, might have been the only "K" flown.
Built without any nose weight and redundant altimeters, it's a blast to fly.

I can see one of these in my near future

It seems like a cool platform to use a huge motor and go mach 2 with a single nosecone deploy with a jolly logicchute release. Most of the other rockets for those big motors seem really tall with payload bays etc. Shorter rockets seem to have more stability than they should at first glance.

Thanks I went through the thread but I didnt see anything too terribly tricky appearing. What were the most challenging parts to get right? The motor tube mount?

Yes, the boat tail makes mounting the MMT a bit tricky, but CJ describes it well.
Not sure what you think is a huge motor, but with only 17 inches of space, a 4 grain is about all you can fit in this rocket.

Seems like the motor can extend into the nose. Sure it isnt minimum diameter, but that should go up a long way and the 4 fins should keep it stable.

Build difficulty is subjective. If you build it without the dual deploy option, yes, you can stick a bigger motor in it but I think most have gone the DD route so you are somewhat limited on motor selection.

I think an eggfinder trs, mount in the nose with the chute, and a jolly logic chute release, biggest motor that will fit and call it good. Not sure if all that will easily fit.

Apparently it will go to 17k feet or so on an L motor. Stability drops to 1.1 at the mach transition, but other than that it looks ok. Mach 2.2. Perhaps I should try to do finsim on it.
