Question: What do you mean by "pinned hinges"?

Answer: When we install the control surfaces using our proprietary composite live hinge material the hinges are glued into place using CA. Then we insert pins through the surfaces and right through both ends of the hinge itself. so that the hinge is trapped into place. The pin is then cut off flush with the surface and pressed further into the substrate. VMAR does this is at least for the hinges are each end of all control surfaces.

Question: What's the big deal? Why bother with this? Why are "pinned hinges" better than "un-pinned hinges"?

Answer: Most ARF manufacturers throw the control surfaces in the box, give you some rough and ready hinges and leave the job of hinging and installing the control surfaces to you. At VMAR we like to put more ARF in all our ARFS so we install your control surfaces at the factory. By using a super strong hinge, gluing it into place and pinning the hinge as well, we are reducing the chance that a control surface will come off in flight. As the builder and flyer of any model, you are responsible for all aspects of flight safety and integrity of the model no matter how much factory work has been done in advance... but we like to help you with this responsibility with a really good hinge, a really good hinge system and pins!

Remember... tug tug tug, test test test before and after each flight. If something is going wrong or loosening up or a sloppy fit is creeping into play, you want to find out on the ground... not in the air!
