One source is Composite Structures Technology. Try them at http://www.cstsales.com.
you are not explaing what your requirements are …
But FAI Model Supply, Mike Mulligan [see NFFS Diget ad] and Andrikov have F1B boon.
Kite suppliers and people like stan buddenbohn and maye a to z as well as some kite places have smaller
Need suggestions for where to find carbon fiber tail booms — CST claims they have never made such an item —
mgewain@gmail.com Try This Man he owned CST and is making the tailbooms
Concerning my earlier post regarding tail booms, I am looking for carbon fiber tail booms for 1/2 A gas models (282 Super Pearl), also for A/B gas (542 Super Pearl). Thank you for any help.
clm_pro.com (Serbia) has:
Carbon tapered Tailbooms from 550mm<1000mm. varied weights, diameters up to 30mm front, 12mm or so rear. Very high layup quality with somewhat pebbly finish that could probably be worked down with 120 grit to shave weight. I am using their item #209 (24mm > 12mm X 900mm X 38 grams) for a series of 400-500 sq. in. F1Qs in the 350 gram range RTF. This is an adaptive re-use of their intended R/C Sailplane components.
The website has “enquery” box used to identify your requirements etc. CLM_PRO. com will reply in short order with price/availability.
Cards and PayPal are accepted. Shipping is prompt in CNC tapered foam blocks. The four booms I order, with shipping, averaged $42 each and are A+ goods. They arrived in 5 days!
I also have two 51″, 51 gram tapered F1C boom/fuselages bought directly fron E. Verbitsky at Lost Hills several years ago. They were $1.00/inch back then and who knows, there may be more of these out there.
Any of the stuff mentioned can be worked pretty easily with a Dremel cutter or in my shop, I pin-hole in rows, then cut with a razor blade or scalpel to form cut-outs. The edges are easy enough to clean up with emery boards and #320 grit to finish. A caveat: There are no doubt paints/finishes available that are carbon and Kevlar compatible, but Krylon Fusion sprays are not acceptable since they seem not ever to dry/cure over the epoxies found on these products.

First, John, thanks for the tip on clm_pro.com. I have looked at them for glider fuselage pods, I didn’t realize they had booms and D-boxes! Yoohoo!
Second, Dephela, also thanks for the tip on the RCGroups thread. Not sure that they are still active, I have emailed and will report back. Their custom domain appears to be gone, so I don’t hold much hope. Pity.
Third, Kit, also thanks for the Goodwinds link. That was the first source I was going to list. I have some of their Allegro and Bubble Dancer booms on hand. I’ve used a similar boom made for the Allegro on RC rocket gliders for international competition (check threads in the Rocket section of RC Groups for some pix of some of those models of mine there… my UID there is gstew, same as here). They worked very well and are very similar to ones I’ve used for 1/2A’s in the past. I plan to use the Bubble Dancer booms first on an F1P, later on a small A gas. Likely good for up to mild .15’s, maybe with a quick and dirty carbon tube front end extension using the braided sleeves available from both CST and ACP to provide extra length at the front. Not sure that it’d be a good fit for the Super Pearl 542, I”d consider the smallest ex-CST / now Matt Gewain one for that.
Then CST used to sell three sizes of large CF booms for mid-to-large gas models:
45.5″ long, 1.25″-.45″, 52gr
47.5″ long, 1.5″-.64″, 65gr
47.5″ long, 1.63″-.84″, 74gr
When Matt Gewain sold the company, he decided to continue to supply these booms himself instead of trying to teach the new owners how to make them. He said he’d do this for several years… so don’t wait too long. You can reach him at the email listed earlier in this thread. I’ve had a recent email exchange with him and he is still doing them, but as I said, don’t expect them to be available after another year or so.
Then also check out the carbon booms available from Mike Woodhouse at http://www.freeflightsupplies.co.uk. His F1A booms look good for 1/2As, maybe his F1B/F1H for a smaller, light one. Mike P at Starlink-Flitetech may have some similar ones. I looked at FAI Model Supply, but did not see any there… hopefully someone can point to theirs?
Finally, those Verbitsky ones sound interesting… I am sure that there are other Eastern European vendors like W-Hobby who can supply appropriate booms, just not sure where to look or how to contact them.

P.S. Places that sell RC DLGs may also be able to supply appropriate booms… check Soaring USA and Hobby Club, for example.
