Mecky33: Thanks for the info, I have ordered 2 failsafes, one for the CEN MT2 and one for the OFNA MBX buggy. I did contact CEN but have not heard from them, I will wait for the weekend to pass then check on Monday and follow up. I read about the transmitter problems and I am sure that is the problem. The MBX buggy has an Airtronics radio system and I will swap out the Xtal's and run it with the CEN MT2 and see what happens. The OFNA buggy has not had the problem. Just hope I don't crash the MT2 again, it is really taking a beating. JT
