Hy Martyn,

This is my answer to your questions:

It has reported that several mounts have gone more of 500 flights without any problem so far.
This is also because:
Carbon fiber cannot be affected by nitro fuels (unlike cheap wood) and is also fatigue free (unlike cheap plastic).
The rubber edges are protected by a wrapping of carbon fiber (no chanche for the rubber to go apart)

Sometimes it happens that someone send me an Hyde mount to be fixed, but that's another story...

His behavior in general is similar to the Hyde, but my mount has a shift that provides the following:
-doesn't allow the engine to move ahead when at full throttle (more precise and constant carburetor control)
-doesn't allow the engine to move up and down under high G manouvers (thrust line constant)
-doesn't allow the engine to wobble (better and constant mixture adjusting)
It has been reported that some cases of mixture problems on the DZ has been solved replacing the previous engine mount with a Modelcompositi mount.

Plus, my mount has a wider and stiffer rear mounting plate that allow for a lighter firewall (for the versions without the front nose ring supporting arm). The firewall itself can be ulteriorly lightened by making a large hole (70mm.) in the center.

All of this, plus being much more pleasant to look at (...) at the same price (or lower) of the other mounts made with cheap materials.

I will not deal about the ratio -cost to the manufacturer/cost to the customer- because there are no arguments to deal with....

I'm here to answer any questions.
