What are You working on?

I'd keep it as is, and just go bigger than you'd normally go with the main chute.  I've broken a fin on 3 of the last five rockets I've launched, so I need to learn more on this as well.

IF I can get back into it, I have on my bench:

1) Competitor 3 (original convolute-wound kit by PR)

2) Upscale of the Hot Pink Suppository of Discomfort: moving from 3″ to 4″ and from 3x 24mm to 3x 38mm.  I'm thinking 3 Vmax motors would give the right kick.

3) LOC Legacy built up for H268R or I200

4) repairs to Excess in Moderation (broken fin), Ultimate (broken fin)

I guess I've got build time while the field dries out.

Right now I have a 3″ minimum diameter hybrid that isn't names.  Comes in at 35 pounds ready to fly and just under 120″ tall.  RASAero says 33,700'.  Last time I few the M900 rocket the sim was within 2% of the actual altitude.

I'm starting to build another 5.5″ Bunny Thumper rocket.  Hoping to fly it on research 75mm motors.

I just ordered some 5.5″ airframe. Looking at starting on something I have been looking at for a couple years.

An aprox. 5X upscale of an AGM-57X HEATSEEKER.

Should come in at 7.71'. I do have some issues with the lower fins. They will be the impact point

upon landing. Even a soft landing may be problematic. Was considering a two stage and let the

lower drop off. Too short, comes in at only about 3.78″. Not long enough to put much of an engine

in. I will just need to build extra robust.

I always made a habit of angling the lower part of the fin, or having some airframe lower than the

fin. Not on this one.

I may change my mind before it starts. Still deciding

Anyway. Whats in the mix for you?
