[Solved] What to do with a suspicious unit?
Since your model is a Nitro model with high vibrations, you have used a softer double-sided tape as indicated at the bottom of the instructions on page 11 of the wizard "Softer tape is NECESSARY on comustion models" ??????
We have tested many tape and the best is the Futaba tape used for Futaba Gyro.
That one is exactly what I was using, I still do.
