Maybe, but it also depends a lot on what motor and ESCs you use, and if the propeller is balanced. If there is not much sound to start with, there is not much that gets amplified.

No, I have a Mateksys ELRS-R24-V receiver in this one. And yes, a very basic BN220 GPS is plugged into it. The ER8GV would probably be a great more modern choice, but it was not available when I got my receiver over a year ago.

@@AxelsDIY I had asked RadioMaster if a GPS can be used on the UART provided on the Rx? Here is their response: “ ER8GV cannot be inserted into an existing GPS. If a GPS sensor with CRSF protocol is developed in the future, it can be used. Now if you want to have a GPS Telemetry project, you need a Telemetry Flight Control that supports CRSF protocol to do this work. , such as Betaflight.”

@@RizHassan Okay, that was more than I knew, I expected them to just take standard NMEA-messages from a standard GPS. In that case, you could look into using Mateksys receivers instead. Using one of there CRSF to PWM converters with a small serial receiver would also work. There are solutions other to get GPS telemetry without a flight controller, but maybe not from Radomaster.

@@AxelsDIY I have free flight related question or anyone on your channel. I am sure you are familiar with E20 timer that can be used for shutting down motor and to initiate de-thermalization sequentially based on time setup. In the old days we use to have a mechanical timers for glow motors. So the question is, can we use EdgeTx timer to initiate a PWM signal to shutoff the motor and initiate de-thermalization to a servo? The idea is to have a RC glider (like my Benny BoxCar) to be used both as RC model and a free flight competition model without any changes to the hardware. I hope my question make sense :)

As an experienced RC pilot, I still think foamies have a place, but I definitely like those kinds of more serious aircraft more. Balsa planes are very enjoyable to build, and they fly better.

No, not with this one. This glider does not have a flight controller. But I will try it using my ArduPlane glider. Keep an eye out for that :)

@@AxelsDIY very nice

The Li-ion battery has a slightly lower voltage. It can't provide as much power (Amps), but it has slightly more capacity (mAh) for the same weight which will give longer flight times.

@@AxelsDIY This means, for example, that the Lipo gives 100% power and the Li ion gives 50% power?

Stabilize (or FBWA mode as it is called) is probably better in most situations. But this glider is very slow and easy to fly. I enjoy flying it in manual mode.

@@AxelsDIY stabilized for takeoff/landing. I use fwba only when strong wind, gust.

@@adbas6201 I looked it up. I Didn't even know about STABILIZE för ArduPlane! But as an experienced pilot, I don't think I would like it. I prefer full manual control, otherwise, I want the full self-leveling behavior of FBWA. It can be nice in very windy conditions as you say.

I am using EdgeTX with ELRS, and the Yaapu telemetry script that receives and displays information from the ArduPilot system.

I will try it!

No, I didn't bother with it here. But maybe, a cockpit camera in the Pitts would be interesting, doing some aerobatics...

Thanks! Nice to inspire.

I know! I will try it with this plane. A future video maybe...

The auto thermalling in ArduPilot works great. Definitely give it a try!

Thanks! If you also change the direction of all the motors: yes, it would have the same effect. In conclusion: "Props in", motors should be angled outwards, "Props out", motors should be angled inwards.

@@AxelsDIY Thanks a lot for your explanation!

But if it were an ArduPilot build, it would have gone into loiter or return to home mode. Then you would have time to figure out the issue, re-mount the module and get it working again to land to plane.

I had two separate BEC modules in that plane as redundancy, and they where working. I was also been able to recreate this issue afterward on the ground, and also with other planes. Note that this is not a problem with ELRS, but with all kinds of external modules in general!

That is also an option I suppose... :)

Thanks. This happened about half a year ago. I have since built a new electric glider to replace this one. A video on that coming in a few weeks or so.

My external ELRS module lost connection with the radio, as shown at the end of the video.

@@AxelsDIY ohh.
