Hi,

The care you need to take with gas ignitions and rx installation is related to the ability of the rx to reject interference. All rxs are not created equal. Some rxs not only tolerate metal on metal but they will tolerate meshing metal gears under load on board the airplane without a glitch. Other rxs are very sensitive to any metal on metal.

If your rx is sensitive to ignition noise or metal on metal, maybe you should consider switching to a more tolerant brand or model

Hope this helps
