RE: SD-10G Range checking
Our tech says the factory spec is 50 feet. However, as I said, I do expect 80-100 feet or so. The RDS8000 range test is longer than the SD-10G because the range test output is simply a little greater.
My go/no-go is 50 feet. But in every case where I have experienced that shorter range, moving the antennas or wiring and/or checking for a noisy component or servo has always resulted in a longer test result. I know people have said they have been fine with a 30 foot range test, but I do not recommend that nor am I comfortable with it.
So, for example, one of our pilots found that his range was diminished (only about 30 feet). Moving the antennas resolved the issue, now from all angles his range test is over 80 feet. The issue was that the antennas were a little too close to the computer for his Turbine engine.
And, as I mentioned earlier, the range test must be performed with nothing between you and the model and the model needs to be up 2-3 feet off the ground.
