Official FlightLine OV-10 Bronco Discussion Thread

[T-CAT]

Has anyone had trouble with their motor mounts melting? I ran my OV-10 for a couple of minutes on the ground to see if I had a couple of extra minutes past my timer. Later I heard some rubbing noise and found out that the mounts melted a bit. Running everything stock.

A couple minutes of run time on the time ground isn't usually advised, and is quite a long time for static testing. Ground testing temps. and airborne temperature of the ESC's and Motors can have a noticeable difference. While flying, the airflow helps significantly to maintain proper temperature of electrical components.

It sounds like you may have been attempting a run-time test to see what theoretical flight time you could achieve on a given battery capacity. One of the many power/watt meters (or telemetry components if your radio brand supports it) on the market for RC can be a useful way to see performance data while running the power system for a very brief period of time (less than 10 seconds is usually all that is needed). With all safety protocols in place, I perform one test at full throttle to note that data and then lower the throttle to half to take note of that value as well. That data can then be used to calculate the estimated potential flight time with the intended flight battery.

Was it a couple of minutes or one minute? Two minutes is quite a long time to be at full throttle. I don't know any situation where you would run a full scale engine for that long at that throttle setting. You can easily overheat an ESC under those conditions.

Tono Even full scale aircraft cannot just sit there on the ground at high throttle settings for too long. Things will overheat in such situations.

I don't call a 1 minute run long. Even full size aircraft can do this. I have yet to have a model overheat like this and melt the mount. There is just poor airflow and the mount is made from the wrong type of plastic in this case. Someone that is flying at full throttle a lot will eventually run into this over time.

How long and high were you running the motors on the ground, and was this before or after your flight? The motors depend on airflow to remain cool, so I would not recommend running an electric prop plane on the ground for any longer than necessary. The same goes with EDFs.

The OV-10's motor mounts are made of the same plastic and general thickness as most of our other warbirds from FlightLine and other brands. Tens upon tens of thousands upon thousands of models in circulation and I've never see a motor mount actually melt under normal use cases.

Airframe components

Canopy Handles
Wheel Hubs


The canopy handles are designed to be installed from the inside of the canopy frame. They are on both sides of the aircraft. Remove the canopy. Cut a hole large enough to fit the handle through the hole from the inside and glue the flats to the canopy frame using contact cement.

The OV-10 has a windshield wiper and I just downloaded one for a helicopter from Thingiverse and used it.

That is amazing & another +10 video; as real as it gets. Keep 'em coming ...

[Evan D]

Looks good!

I thought the OV was supposed to be supporting my mission??

[Alpha]

Violation, Violation! Fire a few warning shots next time

Here's a flight from today. Formation with Ray flying his OV-10 old school way with me on his wing on FPV. EvanD kept violating our airspace with his Freewing Scooter.

Marines and Navy enjoying some flying together... his video is a lot better than mine with the split.

I just noticed the airspace was a bit crowded... was there conflict action going on...? 😁

[thomasnwilliams]

vduniec, did you print the Chaff/Flare buckets? I didn't see the files with the others. Thanks for all your detail work!!!

Disregard I found them, Thanks!

Finally got a couple flights in on my modded OV-10 - 60A ESCs, Eflite Power 25 870kv motors, 5-blade Scimitar props from Eflite EC1500, Freewing 3-axis gyro. This plane now has the performance that I felt was lacking. It can do a loop from level flight without any engine slow down, can go vertical from level flight for quite a good altitude before slowing down. At my 3500' above sea level, it's got a lot more straight line speed. It's become one of my top favorite prop planes (if not the most fave now). I don't even mind the gap between the cowl and the prop base plate.

Warning: Hat Cam.

Hi Eric,

They show up for me here. I haven't uploaded all of them to Thingiverse yet. Make sure you're logged into the Squawk, otherwise you won't see the attached files. That might be the problem.

Just a warning, I had designed these files on Tinkercad so the nose portion isn't as smooth as it should be due to that program's limitations. It's goods enough for stand-off scale though.

Thanks Vic! Funny thing is when I looked again, they were there, so its possible I wasn't logged in when I first looked. No sweat on the tanks they will be perfect for me. I design also with Tinkercad so I know what you mean... A bit of post print finishing and they will be perfect for what I need I am sure.

Cheers;
Eric

Wow Vic;

Thanks for sharing the files, really appreciate it! I didn't see the wing tank files attached on here or on Thingiverse though... Do you have those handy by any chance?

Thanks;
Eric
