I visited the Hobby Emporium when I was working on the Leviathan. They had that E30 and an F27-6FJ. That was sometime in August. I purchased the F26 which I used for the Leviathan's first flight. Remember, CMASS and NAR members receive a 10% discount at the Hobby Emporium. Bring your CMASS or NAR card as proof. I always find it rewarding to support a brick and motor hobby shop. Check out Hobby Quarters in Foxboro, MA. They have a good selection of rocketry kits and supplies.
I'm guessing that the Haz Mat fees came about in 2012. I'm sure someone out there knows for sure.
Even at $27.99 the F67's are a good deal even if it is only $1.00 under MSRP. I used a couple at the NSL 2018 and they were fine. Plus no Haz Mat fee! I'm guessing that there is not much of a margin on the F67's which is why I don't think we will see them discounted very much. Apogee is selling them for $31.02 which is $2.03 ABOVE MSRP.
I've said it once and I'll say it again. We are lucky to have Animal Works. Hopefully we will see Jason at one of the remaining CMASS launches.
I just ordered two packs of Aerotech F67-6 engines from ASP Rocketry for $25.99. They come in packs of two. Shipping was $10.95 for a total cost of $62.93. The cost per engine comes out to $15.73. That's a good price in any league. I used a couple of F67-6 engines at the NSL 2018 and they worked fine.
At $3.00 off per motor that's second best to Sirius' price. So I pulled the trigger on that and picked up two packs myself. A few more packs and I could've gotten down to MSRP per pack I guess... but 4 motors seems sufficient at this point with the season coming to a close.
