Now this thread is back on the front page, just thought I would ask Isaac how the Osmose has held up now that you would have had time to fly a few more contests etc.
How reliable have the electrics and in particular the batteries been? Matt

Hi Matt13

Till now the Osmose has 375 flights without any failure.

The electrics works very well, At the hottest days, here in Israel (35 Celsius), the speed control reaches 52 Celsius, the motor and the battery also come out fairly cool.

The TP 5000 V2 did not survived very long and they were replaced with the new TP Pro Lite 5300 V2.

Isaac,

Regarding batteries performance, how many flights had the Osmose on the 5000 V2 and how many on the new 5300 V2.

Regards

Hi Enrique

The TP 5000 V2 last about 50 - 70 flights in average.
The TP PL 5300 V2 are much stronger, till now, after 70 flights, no problems.

Best regards,

Isaac Najary

Thanks

That's pretty low, how much battery capacity remained after a flight , average?

Thanks

Alejandro

Hi Alejandro,

The P-09 and F-09 use about 3,600 mah with the TP PF 5300 V2,
and about 4,000 mah with the TP 5000 V2.
These numbers are now in the summer, 32 celsius.

thanks for the help anf hope to see you in the comming F3A season

Day before yesterday in competition after 750 flights , still amazing !

Hello Isaac,

What about the batteries, how many flights do they last ?

What brand of batery (model) are you using ?

Thanks in advance for your answer

Regards

Hi Enrique,

I have TP PF 5300 V2 batteries, they last for about 80 proper P-11 or F-11 flights.

Newly I ordered 3 packs of the Power Unlimted Batteries

I hope that they will be as good as they were described.

Best regards,

Here the new brother comes.... ready for test Oct 3rd 2010

SUB.

Excellent old thread. I am about to build my first F3A kit and will use this as my reference manual.
Question: making hinge list for the wing and stab, is it stock triangle list you have used, like 25mmx25mm as an example, and then flattened the angle like I try to draw in my example?

That is one method. Typically the width of the balsa required to make surface LE or TE is not a standard dimension for triangle stock; so you have to use sheet balsa of the appropriate thickness. As long as the center line is straight and accurate once completed.
Good Luck!

Thanks.
I checked another one of Isaac's threads, and it looks like it is usually a 10mm sheet balsa on each part + a smaller 2mm, then sanding to shape
Would this distance be ok as in picture 3, marked in red? ( 10-12mm )
( pictures are from other threads.. )
btw, I'm building and old CA model Fantasy.
