<p>I am looking for a plastic which is transparent to radio waves.  I want to place my transmitter in a cylinder. That cylinder would be placed in a big RC plane  ( whose body is made up of cardboard). I want the plane to be both telemetry, and RC controlled.  That cylinder should allow the signals,  should be strong and light.<br>
So which material would you suggest and is that material easy to do 3d print? </p>

Both tough-PLA and PETG are relatively heavy, which is a disadvantage for flying saucers.

PETG is traditionally tougher than PLA, but with the modified PLA, who knows. I have not personally met tough PLA tougher than regular PETG. </p>\n\n<hr>\n\n<p>SO: </p>\n\n<ul>\n<li>PETG if weight is not an issue. It prints well and it's tough. </li>\n<li>ABS if weight is an issue. It's not easy to print; and make sure it's well well ventilated area (while venting during the print would mess up your print.)</li>\n<li>Tough PLA if you only have cold bed. </li>\n</ul>\n"}]
