[NSRCA-discussion] BOLLY out of business

Fri Jan 16 08:20:50 AKST 2009

One inch wide seems a little bit narrow if you're going to use the traditional "split leg" method. Think about the forces involved here. Especially on an electric where the gear legs are really long. Before you do anything, look at the Prestige setup. The only problem I can forsee is how to make something like it that is a universal fit. Maybe just make the top of the legs somewhat long so that they can be cut to accomodate any fuse width.

We can easily make sure there is enough mounting suface area. Please define your opinion of "enough". I am thinking 1 inch wide by 2 inches per side or so. 

Twist can be reduced. Current designs do not address twist issues at all. Anytime there is nothing but unidirectional zero degree fibers twist will occur.

Re: [NSRCA-discussion] BOLLY out of business

Gray, 
 Good ideas. Some thoughts: 
Yes, splitting them isn't so much the problem. Two-piece gear is plenty strong but there does need to be a reasonable amount of surface area there. Some of the Bolly gear gives you very little to work with. 

Some designs still need the swept gear so that may complicate things. 

The twisting is annoying. If there is a way to reduce that while still providing some flex to absorb the shock of landing then that would be great. 

While we're on the subject of landing gear - what is the best mounting bolt pattern? I've seen quite a few different arrangements.What works and what doesn't?

What did you think about the ES gear twist? That is the wheel going toe in- toe out hitting small bumps. ES had nothing but zero degree fibers. That is the one design issue I am conteplating at the moment. 

Also considering that all new planes are widebody that is what needs to be addressed..BUT having a 1 continuous gear will be more weight. I am thinking it is better to split the gear for a weight savings.  If we make two pieces, and either piece can be a left or a right, then a broken gear is only on one side. Any advantage to that?

Graph Tech is not for us. I am sure their stuff is well suited for the IMAC style planes that they are designed for but too heavy and way too stiff for our use. 
I went through their website and picked a gear based on dimension of the ES. 2+ ounces heavier and twice as thick with zero flex. Broke the gear out of my Black Magic many times when hitting small holes in the runway. Rick donated his ES gear and life has been much better.

Anyone have any luck with the Graph Tech RC stuff?  Only experience was with some smaller electrics that worked just fine. They have carbon pants and spinners, as well.

Thanks, Jim.  Those are $112.00 I think… about double that of the Bolly…. Not sure how that will go….. but if there are no other choices…

I just received conformation that BOLLY has gone out of business.  Unfortunately, this is a major supplier of CF landing gear and wheel pants.  I have been awaiting a shipment of several items, and now it does not look like that will happen.  I am working now to determine if there are any gear/wheel pants available.   

The really bad thing is that I am not sure what options we have left, other than going with a kit/arf manufacturer’s gear.  Ed Skorpa dropped his gear last year…
