Here is the cheapest Xoar propeller I have found http://www.electriflite.co.uk/store/...s/pjn12x4.html
But they dont sell it in the pair unlike others. Could it be a problem? Is the pair better matched/balanced?

BTW the Zenmuse crashes are realy heartbreaking. And the stabilisation unbelievable!

Aleksey,

One question, at first post you put your config with a 5000mAh 4S 15C.

Still using that battery? It's realiable with MT3506-25 motors ?

If the maximum continuous current for each motor is 14.5A all four max = 58 A

So the 5000mAh, 15C = 75 A ... considering power for Gyros and Servos, Video transmitter, it's reliable?

I have been using the Zippy's for about 200 flights, they are on their way out already but got my money's worth. Thunderpower 25C is the way to go, they still fit in the narrow frame, 45C's are too heavy and wide. Expensive but still full capacity so suspect that overall cost is about the same as a Zippy if it really last 2.5 times longer.

Thanks! I have some batteries Turnigy nano-tech 4500mAh 25-50C and other 35-70C that almost same weight, and one Zippy 5000 mAh 40C that is very heavy, i will buy more and will try 25C.

About using cameras like Sony CX760 with more weight, there is any frame Ecilop-family project ready?

Or the ecilop can handle 500g or 600g camera?

Thanks!

Most props we use do not come in balanced pairs, Xoar being an exception. So while the balanced pairs may have slightly better properties, I would wager that these are just fine.

OK. And they seem to be predrilled for 6mm. I have MK3638 with 5mm shaft. Can I drill it to 5mm? Also I am afraid because it must be done very precisely.

No, the 6mm hole is already larger.

Are you sure you have 5mm hubs and not 6mm? Otherwise, I saw these that should fix your problem.

I'm not so stupid :-)
You did not understand me well, sorry. I meant there is not hole through. It is predrilled, not drilled. So there is only little hollow or dimple or how to say it. I dont know the english word.

interesting. jus opened up one of my hk401b gyros.
and it seems i have this new type gyro.



now alot of what i have read online about this gyro, is that the new one is really sensitive and twitchy compared to the old one.

i have a feeling my roll gyro might be an old one, but all my others are the new type one. because i can have the gain on roll almost full before it starts twitching.

Gradually getting there - I managed to get a couple of HK401b's at last and fitted them instead of the GY520's, as well as a new Tower MG930 on the roll (to try to eliminate a twitching MKS9760a). This immediately cured most of the pitch pitching. The GY520's worked well at handling the major movements, but I could not dial out the mild swinging that followed compensation. The 401b's cut out most of the problem but are very sensitive to gain adjustments. I have 10 set in the naza assistant for roll and pitch, then nearly the same on the servo tester (ie 15% beyond the centre point).

This first clip was around 20% on the servo tester, second clip reduced to about 15% which was an improvement. Any lower and the horizon rolls, any higher and it starts twitching...not sure what to adjust next?

conditions: light wind

Ecilop tests 401b (0 min 45 sec)
