These are great! I tried tracing the control horns from the free plans and cutting them out. They didn't turn out so well.
Buying and using these laser cut control horns was faster and easier more precise and ultimately got me in the air faster. A great option for scratch builders or replacement horns when crashes occurs.

They are strong and versatile, having three holes to choose from. I like them and have bought them before.

Haven't used any from this pack yet, however, based on how well the ones that came with the kits they should be fine. So far the ones that came with the speed build kits have worked great and I expect these will be just as good.
