[NSRCA-discussion] Bolly Clones

Sat Nov 7 18:41:39 AKST 2009

It;s great to have some options for landing gear, thanks for reporting the specs.

You mention the pretty woven cloth legs in respect to the carbon tow legs of the bolly gear.  The Carbon Tow running in the strength direction on the Bolly gear leg is what really allowed them to produce a strong gear that was also extremely light.  While this may not make for the prettiest gear legs, it is just good engineering.  The woven cloth with fibers that are not parallel to the loads that are placed on a gear leg are simply not taking full advantage of the fiber's strength, and thus will require more fiber for the same strength.

I tried to post this earlier but haven’t seen it, so I’m replying to your post to see if it’ll load.

I just received a set of GraphTech's new F3A Pattern Long(slim) landing gear.
The weight is 132gm, has a 9 inch rise from axle to fuse, spread is 19in. Dimensions are 1-1/4 inch wide at fuse tapering to 1 inch wide at wheel. Sweep is 1-1/2 inch.
Beautiful with full carbon cloth wrap and clear coated, not just made of carbon tow like other gear used to be. Price was $69.95

Mike also told me 
“I have some other pattern stuff coming as well. Look for Aluminum Coated Graphite axle sets that are half the weigh of Titanium. And I am also working on Matching Carbon Wheel Pants for the #270. Trying to work off all the weight in the landing gear area!

If you're interested call MIKE @ graph Tech 832-325-0328

That's great news as it's always good to have choices among quality pattern products.  When Bolly went out of the R/C landing gear business, I contacted GraphTech RC.  They agreed to produce a Bolly replacement for electric 2 meter pattern ships.  I have several sets and they are exceptionally well made with a very high gloss finish.  The sweep back is about 1/2 that of the Bolly Long which, for me, resolved the tendency of my PL Partner to nose over when trying to taxi on a grass field.  The Graph Tech carbon wheel pants are just a hair shorter than the small Bolly F3A but are a bit wider and taller which allows the use of larger wheels....again, for those who might have to deal with grass fields at a contest.  The cost of the Graph Tech landing gear is $69.95....very reasonable compared to what I've paid in the past for carbon landing gears made outside the US .

>I recently found out that Randy Johnson, a control-line legend, former North America Bolly distributor and owner of Aeroproducts, made arrangements with Bob McDonald, another legendary control-liner to produce clones of the Bolly carbon fiber landing gear that went off the market last year. Bob doesn’t live too far from me so I went over to see what he’s got going on. He showed me a set of F3A Electric that are identical to the originals. They’re laid up the same with the same combination of carbon cloth and tow that result in a gear with just the right blend of stiffness and flex. These are exact copies, not just an attempt to make something that looks the same. Bob’s doing it right and cooks every set in an oven to get the maximum strength out of the epoxy. I provided him with the Bolly F3A Long gear off my Integral so he could clone those as well. I just saw the first sets out of the mold today and they’re great. I’ll be putting a set on
 my new Integral which I’m just getting started on. Randy Johnson is the exclusive retailer of the gear and you can get his info at  http://www.aeroproduct.net/. He still lists the old Bolly gear on his site so you’ll have to inquire about the new ones by phone or e-mail which are both available on the website. Bob asked me to mention that he’s not selling the gear. You’ll have to get them from Aeroproducts. Bob tells me that Bolly wheel pant clones are also in the works from another source and will be available soon from Aeroproducts.
