I've got a RAM 1000 Electric Start ECU that has been giving me problems. The turbine and ECU have run flawlessly during the first 15 cycles. However, I recently had to send the ECU back to Electro Dynamics because the humidity in my flying area was to high and it would cause the ECU to sometimes work and sometimes not. E.D. "sealed" the bottom of the ECU so that the crystal inside would not be affected by changes in atmospheric humidity. After I got the ECU back, I reinstalled it in the aircraft and completed two starts. Everything looked fine so I started the turbine a third time and flew the aircraft. The flight went well without a hitch. Here is were the current problem began. Preparing for the next flight, the ECU would not light up indicating that it was not working. This was confirmed by the ground start box showing a bunch of black boxes in the display(it usually shows me prestart data). My question is that is this common with a RAM 1000ES ECU? I like most turbine modelers have way too much invested in our aircraft to risk losing it on a turbine computer error inflight. Can anyone please give me advice? I have thorougly gone thru the entire aircraft and all of it's electrical/battery connections. I called RAM and they said that they no longer service this ECU and suggested that I upgrade to the X-series ECU Autostart system for $995. I bought this system new from RAM just over a year ago and only have less than 20 cycles. Please help, anybody. Thanks
