Default Modelcompositi composite engine mounts

Hi Doug, thank for the nice words,

The reason why I got in production with my mount was not because I wanted to copy another product already well established into the world market.
It was because Sebastiano Silvestri made some testing on the Hyde mounts he was using, discovering the problems I issued in the past posts.
He suggested me to try to make a mount that could solve such problems, being lighter and more reliable (There are Hyde mounts that last 3000 flights and mounts that fail after 20 flights -proved-).
After having made some prototypes, we agreed that the retaining pin was an improvement over the ones without it.
If I wouldn't put that on my mounts, they would cost less so that I could sell more of them.
On request, I can produce mount without it easily. No problem.

My mounts too are made by hand (my hands). To make a carbon mount is simple: cut 7 to 10 layers of carbon fabric for each part the mount is made (6 parts), lay them down imprgnated with epoxy resin into each mould. Let them cure at 90°C. for three ours. Take them out from the moulds, trim them to measure with diamond tools, and assembly them togheter with 90°C. cured aircraft grade adhesive in a 3 separate oven steps procedure.
It takes 3 to 4 times the time to make an Hyde one (I tryed to make some mounts the Hyde way for comparison)

A full sq yard of carbon fabric is needed to make ONE mount, we all know his cost.

If I just wanted to make business, I would have made exact Hyde clones selling them at 1/3 of their actual price.

For a product, to have been using it for 15 years, it doesn't mean it is impossible to discover that a better product can be made. (Otherwise we would go with old Wolkswagen Beetles until now...)

Anyway, I don't want to make a soft mount war.
The USA resident people are not allowed to buy my mount because there is an US patent on that. Right.
All the rest is free to decide what to do with their money by themselves.
