spektrum 3300t problem
 

I upgraded to Futaba in my 5ive and in doing so I sold the rx on here....

The buyer is saying the rx trips the engine alarm on his dx3s and dx4s even without the sensors installed...

I ran this rx on a dx3e/dx3s without the telemerty garbage with no issues and I do not see how it could trip a alarm with no wires hooked up???
