I'm Looking for a cowl manufacturer that makes their fiberglass products with polyester resin not epoxy resin.

Please post Names, links or phone numbers.

Thanks

Not sure if these guys meet those specs but they are the best when it comes to aftermarket fiberglass products. www.stansfibertech.com

Thanks for the link Steven. On the home page they state epoxy resin.

Fiberglass Specialties is another great place to look for cowls and things. Good Luck, Dave

Dave, I'm familiar with Fiberglass Specialties (right in my neighborhood). Same deal epoxy, unless they changed in the last couple years. Guess it's worth a call.

Thanks

From the standpoint of the modeler, What is the difference?

Good question! I didn’t know any difference either until a member in my club that is retired from owning his own body repair shop and has built close to 200 planes explained it to me. To vastly paraphrase his words; cowls and wheel pants made with epoxy resin have a flawless finish that is ready for prime and paint out of the box. Many modelers like that feature, however they are brittle and crack easy from vibration or mounting hardware installed to tight. Polyester resin parts on the other hand requires more work to finish but is much more durable.

He had a favorite supplier for “Poly� cowls and pants but they have since changed hands and moved. He couldn’t remember the name of the Co.


* spuck5644 & WORNBOOTS Thanks for the info

With all due respect, I disagree that the epoxy cowls, etc. are more brittle, etc. All pattern planes went to epoxy long ago. Lighter in general, and able to withstand many, many hours of practice without failure. And I have had quite a few of Stan's cowls on various planes up to 1.5 powered, with never a single cowl failure. Some of these are on planes that are nine years old and still look like new.

Stans makes GREAT fiberglass parts and maybe sometime you will try it out. There awesome and are much nicer then the stock cowls and wheelpants with many of todays arfs.

Clair, thanks for the input. Before a couple weeks ago I had no idea there were different resins for fiberglass. For years I thought a fiberglass cowl was no different than any other. Until I get contrary information with epoxy vs. polyester resins, regarding durability, I’ve got to go with the man I’ve know for 13-14 years and learn from his vast experience.

The Stan cowls you mentioned are very likely a thicker, better quality than the epoxy cowls experienced within our circle. When the topic arises at the field again I’ll include your input. Do you have a web address or phone number?

I'm looking for a fiberglass cowl for a Hangar Design Sea Cruiser. That's the one with a triple rudder. If not available, how could i get one made?

If it turns out you go with fibertech...and you need it for a 40-size extra 300...I've got the cowl and wheel paint's (brand new) e-mail me...

I'll give Stans a vote on this one. Curtious, prompt service. Can't beat that.

I have a few of Stans parts and will attest to the EXCELLENT quality and durability and great customer service.

IMCP: call Stan and ask about getting custom parts. I talked to him a couple of times and he was very interested in doing a custom job, even though it was small. (wheel pants to restore a classic TOC plane)

Don't try to solve a problem until you have a problem. It doesn't sound like you have ever had a problem with epoxy parts.

You stated that your freind was in the auto body business, they have much different requirements than we modelers do.

It's like saying "I need a titanium frying pan because titanium is stronger."

This topic got dug up out of the archives.

Dynodan, not sure what gave you the impression that I have not had previous troubles. Discussing cowls with the fellow club member (the body man) enlightened me that there are differences in resins used and this is more likely the cause of failure rather than workmanship.

Since the time this thread originally ran I’ve talked with Aeroglass that uses polyester resin. They told me that comparing a poly to an epoxy as far as durability and one being more brittle than the other couldn’t be done due to the fact that there are so many different variations in each category. This makes my buddies statement only partially true, the division isn't between poly and epoxy but the subsets of each.

At Areoglass he did say that one advantage to a polyester resin is that glue will stick to it so if it cracks it can be glued together. Now I’m doing some major paraphrasing here so if you want the straight facts call the nice folks at Aeroglass.

I know more about fiberglass than I did which is still way more than I need to know.
