Flite Test style control horn

This is a control horn similar to the ones used by Flite Test for their excellent Speed Build Kits and swappable R/C airplanes.

Use it to replace the ones you got with your speed build kit, or if you are making a scratch build using the plans they have available for free on the site - www.flitetest.com.

These guys are doing great work. Support them by buying from their store and subscribing on YouTube.
