Custom modded Estes Outlander. Original was said t' be underpowered and have unstable/unpredictable flight.  Since I thought it be an awesomely cool "definitely nay 3FNC" design, arrr, I went about fixin' t' said deficiencies. Avast, me proud beauty!  First I started with a 24mm Motor mount so that I can fly this heavyweight on D12s. Aye aye!  Next I noticed that t' "fins" (lander legs) were designed so that they can actually flop around!  Can you imagine a rocket with 4 floppy fins?  I fixed that with added "bushing" spacers usin' balsa shims and I also notched t' end stop a bit so that t' fins stay in place on lift off. Avast!  Seems t' have worked well since first flight was a very good one. I also added 1oz o' clay t' t' nose since I be flyin' on Ds.
