Solder them or check for ' rca female ' pin at local shops.

Have you tried rc hyper?

just .5 mm extra BUT the Shop is really good and so are its owners.
One of the best in india

Sir, will you please change the title of this thread from "Selection of motor for tern" to "Building a solar plane"

Thanks in advance,
Karthick Ashwath.

Here is the video of my solar cell test(6"x6" polycrystalline)

Test results:
The setup is just the solar cell wired to a multimeter.
The voltage reading is fine. - open voltage is 0.6V
Short circuit current = 12A

All this meets the manufacturer's data.

So the actual power with a proper load will almost certainly be 4W.

More updates coming soon!

I have decided to change course and build a stock FT flyer with my electronics(DT750,2200mah 3s lipo,60A esc)
I will use depron instead of the super heavy foam I used before.
It is highly realistic and the expected AUW is 550g
I will be posting more updates soon.

Friend, it's not feasible.
A 2200 is heavy, dt750 is a overkill.
Go for a ft explorer.

I am going for the simplest plane. Wing loading is under 16oz/sq.ft.
Its running a 8x6 APC SF prop.

My avispad has a loading of 13 oz /sq.ft.
It will be a brick, friend.

Aerobatic planes have a loading of above 15 oz/sq.ft.
Why don't you go for maxeon panels?
Light, cheap and efficient.

Just tested the maxeon cells I received.
Volts- 0.624
Temperature- 32⁰
Amps- 0.6??
At first place, thought something wrong with my multimeter. Checked with various power sources, the amp reading is accurate.
The cells which should produce around 5-6 amps are producing just 600mA.
Looks like a defective batch. Has anyone worked with these before.

I have,
They work just as specified.
I used them on my solar plane.
It flew magnificently.
My batch was quite okay....
Further, I see that you have not connected the three sub-cells of the single panel in parallel together.

When I measured one, it was low.
Wire up all of them together, you will get 6 amps.

Did you connect them in series?

The three tabs of the cell are internally connected. I checked them with a continuity tester.

Just connect them even though that.
It just works that way. Don't ask me how.

Ok. I'll check it again ,connecting them.

Ok. Connecting the tabs together did not play any role in increasing the current. However after connecting 2 cells in series the output was around 1.6A. Maybe, this is happening due to the internal impedence of the multimeter. Looks like the meter is not able to calculate the current for a small voltage.

I connected 8 together.
Then was I able to get enough current

Yes I am planning to use maxeon cells I just wanted to test my own cell that I had.
Thanks for your data kiran sir.

How did you avispad fly?What happened to your solar project?What wing loading are you recommending?

Avispad (VT-SHR) is finished.
Two planes; a Pilatus pc6 turbo Porter and Stevenson's windy are being constructed.
My solar plane was completed ages ago. Won the second prize.
Wing loading is recommended to be below 11 oz/ sq.ft.
I am not so confident with my Pilatus. The wing loading is coming out 15 oz/sq.ft. That scares me.

Hai .... friend's any one tell me the difference between pull and thrust rating in brusless motor
..it make me confused

@prabal276,
Prabal, this is Karthick's thread.
Where is your own? Bump it.
Want to know fate of your Pilatus. Will post a pic of mine
