Good looking plane, it should be really visible against the sky or clouds.

Thank you. I had to drill out the prop. I'll instill the batter bay and hopefully maiden soon!

I have a GRXL here ready to start building on. I want to set it up for FPV and would like to aim for 20min flight times with minimal weight. So I want to avoid just strapping more batteries on for endurance.

The obvious thing to do is minimize drag, so trying to keep all the bits inside will be a goal. Nice smooth surface for the airflow.

The part I'm less sure about is the power system. In general, am I better off with a longer prop and lower KV motor to match? I was considering the NTM3536 1400KV with a 10 or 11 inch prop. I would probably get a few pitches to put on the wattmeter to check before flight and use a current sensor durring flight to verify performance vs consumption. I'm willing to spend a bit more on the motor if it helps noticeably with efficiency. I'm just familiar with that one.

As it's for FPV, I don't need to have a speed demon. I want enough thrust to make launching reasonably easy and have an OK climb rate, say, 30 degrees. No unlimited vertical etc. needed. But still able to cruise around without killing batteries.

Keeping the weight down is a bit of a challenge to myself. I keep building heavy, so I want to try the other side this time.
