On my last flight I found the throttle setting where level flight (SAFE On) exists with full landing flaps. You read on the top line of your DX TX display. My setting is 46 percent. After landing I opened up the throttle curve program and turned it On and set point 3 at 46 percent. Then I set point 2 a little below at 41 and point 4 at 54 percent. This gives a flatter throttle slope to allow fine tuning when I turn onto base and final approach. Now I can reduce throttle to a nice glide slope setting and just use rudder to maintain localizer/azimuth/runway centerline. Its no Cat 3 but much better than prehistoric RC flying.

In my last post I mentioned my interest in building a Micro 2.5 inch quad primarily 2S (meeting MultiGP MIcro class specifications) with some 3S.
Below is a video of how I went about choosing each of the components to include the options i was looking at. It includes the parameters for each component I think are important, options for each component, components specifications compared side-by-side with each other and my choice for each component. This stuff may help out others fairly new to builds also.

After losing my other spitty to an electronics failure, I bit the bullet and built another one immediately after
This one has a few mods that made it better than her deceased sibling...
- Shorter and lighter tail for a better CG location without the need of ballast
- Much better retract mounts and wing doublers for reinforcing the mount area
- Better colour contrast for camouflage paint finish

Maiden was a huge success and I've been flying it regularly since then.
Awesome plane!

Update:
Thank you for the community's help! The cause of the crash is because of a runaway prop.



Background info:
I have recently bought nolimitdronez mod software trying to remove the maximum height limit of my Mavic. Downgraded from V01.04.0400 to V01.03.0900 in order to get the height limit removed. Planning to test the limits in the countryside of course. However, the firmware of the controller is on V01.04.0400 and has not been touched. I'm was using the MODDED DJI GO APP (For the first time). https://sparkpilots.com/threads/dji-...r-4-1-15.3841/

Before crash:
I was flying my Mavic on a grass field 100 meters away from a tall building to take a look. Everything was working normally and suddenly the motor stopped working or a prop flew off or something. The aircraft started spiraling down, I tried to restart the motors with success but according to the log file my Mavic fell even faster after the attempted motor restart.

My Suspection:
I either lost a prop in flight or it was the MOD that caused it. However, I would like to know the exact cause.
I have checked the log file and there are quite a few errors. Such as MOTOR IDLE, GPS POSITION NO MATCH, there was also missing data for 16s right before the motor went out.


Note: NO ONE WAS INJURIED! My Mavic crashed on a grass field and there was no one around(Except for me). Fell 2 meters away from me. Definitely scared the crap out of me

Zip file attached includes the DAT log file, TXT log file, and xlsx file converted from the TXT log file.

Thanks in advance for the community's help!

which did not mention in the video, is the drone has a built-in dvr recorder on the side of the drone. So you can use a 32gb sd card.

I like to stop the prop while gliding especially if I use a folding prop. Here is a link to the ESC Instructions.
https://www.horizonhobby.com/pdf/EFL...CInstSheet.pdf

I was able to get to the two fast tones programming step but no further. I called Horizon Tech and they said the Cirrus ESC can not be programmed. I could get a Maule 40 amp ESC for $30 or a V900 60 amp ESC for $60. Both are programmable.
I ordered an Aerostar 60 amp RVS ESC. I use it on my Maule with floats that has flaps on channel 6 and reverse on channel 5 using the 3 position E switch. The Aerostar is easy to program for prop brake. You have to have the prop stopped in order to have the ESC reverse the motor/prop direction. Reverse should be fun on the Cirrus for stopping and backing up on the runway.

I have many places where I fly RC and I have to carry the model and TX out to the runway or takeoff spot. For models like the high wing Apprentice, Valiant, Beaver, or Maule I use a retractable wire handle to lift and carry the model. The handle can be used to hang the model from a ceiling. The low wing Cirrus is different and so I use 65 b Spiderwire fishing line attached to the fuselage. I wrap the line with a clove hitch, put a drop of CA on the knot/toothpick and sink the tooth pick into the foam fuselage. When dry I test the pull strength of the string and joint.

Can a PASSENGER land a PLANE? Presented by CAPTAIN JOE (15 min 51 sec)



After months of thinking about the problem, it became clear the passenger should fly manually instead of trying to reconfigure the autopilot as depicted. We're all familiar with the basic airplane controls, have played flight simulators, & can drive cars. Getting the plane to point in a certain heading & controlling speed isn't very hard.


The autopilot is a horribly complex addition. Most of the radio time is spent explaining how to use the autopilot & looking for the controls. She had to lower flaps, lower gear, & reverse thrust, despite the autolanding being engaged. A 2nd passenger could have managed the flaps & gear.
To the lay lion, manually flying would greatly increase the chances of success, but Caption Joe based the video on no doubt what the FAA recommends.

I have improved my polystyrene foam cutter. The cost to build was about $10. Using household tools, a drill, soldering iron and glue gun it was complete in a couple of hours. The size accommodates polystyrene foam up to 1" thick. It is portable, powered by 2 alkaline D cell batteries. 3 inches of very thin steel wire is heated by resistance to just beyond the temperature polystyrene transitions. Polystyrene is safely cut in a ventilated area. The heat is minimized to avoid unhealthy fumes. As a result, cutting speed is more or less 9 inches per minute depending on the size and density of the PS. The cut is barely larger than the diameter of the resistance wire so detailed and accurately sized pieces and voids can be achieved. It also cuts thin molded PS (recycling symbol 6). The platform lifts off to change the batteries or resistance wire.
Resembling a pizza box, a 12" square frame made of 1.5" x .5" poplar with a .25" paper board top and bottom. The lumber was cut with a small hand saw. The top board is left unattached and small blocks are glued to the underside which keeps the top in position on the frame.
A light steel rod is bent at a right angle. One end of the rod is fitted into a hole in the frame and held with a set screw. The point of the screw tip is ground off. The arm is parallel to the surface at 2" above. The negative battery wire (22 AWG) is inconspicuously soldered to the rod using a heavy soldering iron. The resistance...Continue Reading

RC Tip #18 - Bad Wiring Assemblies



Here is a link to the Video:
https://www.youtube.com/watch?v=l9g_1-JT0KY

I have ordered power connector pigtails, extension cables, servo wires, etc. and approx. 25% of those have had bad wiring assemblies.
What I mean by bad wiring assemblies is the wires in the connector are not in the proper order.
I have had to remove wires from these connectors and re-install them in the proper order.
Never assume that the wire assemblies are correct and always check before you use them.
I installed a servo pigtail into one of my receivers and shorted out the receiver because the power lead was installed where the signal wire should have been.
I didn't check before I used the wire assemlby and it cost me a receiver.

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!

Been wanting to add a nice somewhat large glider to my airplane arsenal. Something for those lazy/relaxing days. Found some plans for a Flitetest style glider (called Galaxy) through the Flitetest community pages. Currently have the fuselage and tail section built. Next big step is the wing which I am actually going to make as a 2 piece wing with a split in the middle so I can take it apart for transporting. The original design was a full single piece wing that used 3 sheets of foamboard.

Here is a video on the start of this journey in constructing this big glider.
