Brief:
For the most part, I'm not much of a scale fan but through the years there have
been several scale rockets that I always had an itch to build. The original
Estes Mercury Redstone was always a favorite, as were both versions of the
Little Joe. Another member of this club was the Bomarc. Bomarc kits are seldom
seen since Estes discontinued their version
Construction:
When I saw the Empire Rockets kit on an ROL auction in the fall of 2003, I
placed a bid and, much to my surprise, I won the auction. That should have been
the start of a beautiful "man meets rocket" story. It wasn't.
When the kit arrived after a delay of several weeks to correct a problem with the ramjet cones, I found that there was a problem with the ramjet cones. I emailed Empire about the problem and was promised a replacement set, but no set ever arrived. Just that quickly my ardor for the project evaporated like a steam cloud. After that, whenever I noticed a post on The Rocketry Forum (TRF) asking about Empire Rockets, I told my story just to keep anyone else from winding up with an incomplete kit like I did. Apparently the Empire folks keep an eye on TRF, because in February, 2006, a whole new Bomarc kit showed up on my doorstep without explanation.
The parts list:
The second Bomarc kit arrived in a plastic bag with no header card or hang tag. All of the parts were in good shape and the ramjet cones fit like I always hoped my first set would. I found the instructions to be decently written albeit somewhat complicated. (Although I should add that since this was marked as a skill level 4 kit, I didn't think they were excessively complicated.)
Construction wasn't difficult and there was nothing that I'd have considered as a "gotcha". Making sure things square up isn't difficult, and taking the time to do this makes a definite difference in the finished model. I have to admit, I was more than a little impressed with the model that resulted from my efforts.
Finishing:
I flew the Bomarc unfinished due to time constraints. I had taken the time to
fill, seal, and sand all the balsa and tubes so it was ready for paint. It
would have looked great as a desk model once it was painted and applied the
decals. If only I'd have kept it on a desk. From a cosmetic standpoint, all I'd
suggest for this kit is a better set of pictures for painting. I'd also suggest
that Empire should include decals.

Flight:
Empire recommended a B6-4 for the first flight, but I went with the C6-5 due to
the weight of the model. The model balanced near the front of the ram tubes
which seemed within reason. Winds were topping out about 6 to 8 mph, but were
more consistently around 3 to 5 mph. This also seemed within reason.
The rocket looked fine on the way up until around the 50' mark when it suddenly changed from vertical to horizontal almost as if it was rebounding off of an unseen glass ceiling. It flew back over the flight line and for a moment looked like it was going to hit one of the large concrete bases that were left from the towers that once stood at the VOA. It just missed and disappeared behind the monolith. I was disappointed and slowly began making my way over to pick up the pieces.
I found the rocket sitting near a black patch of grass. It took me a moment to realize that the grass was black because it was burning. I yelled to the two guys I was flying with and between the three of us we were able to get the fire out before the fire department arrived. (If nothing else, I developed a whole new respect for firefighters--that's tough work.) In the end, the body of the rocket was spared, but the nose cone, parachute, and shock cord were destroyed. I was pretty sure my Bomarc days were over.
Several weeks later, it began to gnaw at me. This kit had been sent to replace an incomplete earlier kit, and I still had the parts from that first kit down in my shop in a bag. After locating the nose cone, I mated it to the body of the second kit and set out to find some information about trimming a Bomarc for flight. Someone who'd had experience with trimming the Bomarc suggested that I trim it so that the CG was 1/2 inch in front of the ramjet cones. I stuffed enough clay into the plastic cone to bring the CG up to that point. I then waited for a scheduled flight weekend that wasn't either rainy or windy. Then I waited some more. It took until May for us to get a suitable weekend, but it was worth the wait. With nothing but a very light breeze I loaded the Bomarc with the B6-4 that the directions specified for the first flight.
The flight was markedly better than the previous flight but wobbled throughout the flight and never looked to go past the 100' mark. Ejection occurred just as the rockets forward motion stopped. While not perfect, the lack of an actual crash made me think that with the added noseweight, more power might be the answer. Instead of leaving well enough alone, I immediately prepped it for another C6-5 flight.Once again, the C6-5 proved to be the Bomarc's nemesis. This time the rocket didn't even leave the pad looking like it would go straight. Instead it swapped ends and landed in the tall grass, fortunately still damp from rain the previous night. It smoked through the coast phase, then blew the nose cone into the soft earth, officially ending its career as a flying model.
Recovery:
Recovery was a bit hard to judge as the parachute was only used on one out of
the three flights. One parachute melted in the fire, the other one worked on
the one flight but never got unfurled due to the third flight being on the
ground before the boost phase had ended.
Flight Rating: 2 out of 5
Summary:
After two years and three months, I was really looking forward to flying this
rocket and I was determined to put the customer service experience behind me.
The Bomarc builds great and I have no doubt that it would make a great looking
bird when finished, but based on what I saw, it has no business flying without
modifications or, at the very least, trimming instructions that are as detailed
as the build instructions.
PROs: Decent quality parts. Well thought out assembly instructions.
CONs: Terrible customer service. No trimming instructions.

I bought and assembled a BOMARC model way back in the early 70's. At the time In was stationed at Hurlburt Field, Fl. I was an electronic technician, working on the BOMARC missile. When I finished with thr model, it looked so good that I would not fire it. I just sat up on a stand. As fate would have, my son put it in a chair and a few minutes later, he sat on it. Just today, I ordered another kit. I hope it turns out a good. Im have been looking for many years, and finally found it.
