Mini Talon QuadPlane Conversion

Looks good. Like me, you are a risk taker using a camera on the first test flights! :slight_smile:

great topic, amazing works!..one question: why didn’t use small motor as forward propulsion, like: Cobra 2221/16-940 kv or SunnySky X2216 1250KV. Why you choose a 2814 size?, is it too big for this plane, isn’t it?..I have 3 Minitalon, not Quadplane, with this size of motor and takeoff without issue by my hand. :face_with_raised_eyebrow:

Hi Juan Pablo,

It is true that many motors can be used on the mini Talon. When converting the mini Talon to a QuadPlane, there is extra weight and drag to burden the flight so the 2814/16 motor has proven to be very efficient on a 4s Lipo pack with a 10x8 e-prop. The measured values are in the chart below.

Thank you Greg. I will try both size of motor, as you advice. How about try to extender the wings. It will improve the performance, i think. And it allow less cruise speed.

Hi Juan Pablo,

“Improving” the performance depends on the user’s goals. Most people want the higher speed for FPV and see no need to modify the wings. You can see many FPV videos here of the mini Talon on long range flights along the coastline or vast open areas.

In my opinion, the mini Talon flies great with stock wings, with or without QuadPlane modifications. When converted to a QuadPlane, you no longer need to hand launch it and can land in a small clearing at the cost of increasing the drag and reducing overall flight times.

Cheers!

Ok Greg, thank you so much. Another ask; I saw your post about SERVO_AUTO_TRIM command in order to trim a new plane. One question: after the first success trimming the SERVO_AUTO_TRIM should return to value 0, or It have to remain in the value 1, for ever…thank you much…again

That’s a good question. I am leaving SERVO_AUTO_TRIM on, and do not see any ill effects, but I am not certain if this is desired.

Greg – are your booms the full 750mm long or did you cut them? I am making a version of yours and have the same HK CF tubes – 750mm. Thanks.

Hi Marc,

I cut off 300mm so the length of each CF boom is 450mm.

Cheers!

Thanks Greg. Have you passed the wires through the middle of that CF tube by drilling exit holes?

I think I am going to make my booms easily removable with a 3D printed parts. The DJI E305 set that I am using is saving me almost 100g on your motors and ESCs so I have some weight to spare!

BTW, I went looking for Quadplanes threads and I see you have converted just about every conceivable plane into a quad. There should be some sort of merit badge for this!

Marc,

I created two slots near the middle of the CF tube using a Dremel tool. They only needed to be slightly wider than the width of the wires.

I would settle for some descent weather to test my new conversions. It’s been a rough spring!

What I thought. I will do likewise.

We have only just started to get nice weather.

Looks like Cobra C-2814/16 1050Kv Brushless Motor is out to stock in the hole world :o anyone find them just now?

hey i start new project!!
There is an option you upload the final frimware?
and i only flash it to my px4 bard?

can you send it agin plase?

Hi Hiam,

I am using the standard APM Plane v3.8.4. You can download it via Mission Planner directly into your Pixhawk v2.4.8.

Use this section for first time setup in Plane. Setup for Plane

Cheers!

Greg C.

thanks ! im new to pixhawk i is away you can send me the file
and i can load or flash my pix?

The firmware file for the Pixhawk v2.4.8 is automatically downloaded from Mission Planner. Use the link below to install Mission Planner and upload the firmware to the Pixhawk.

Thanks for answer!

Yes I know
What I’m try to say it’s impossible to make backup to ur pixhawk with all the settings and parameters?
That I’m only load file and all ur settings will be and I only plug and wiring the plane?
