OK i figured out what the pots are.

G,
Not sure why they would have the boot loader as that should already be on the processor in a protected area. Maybe they mean flight firmware?
Can you post the .txt how to for us to check?
Cheers,
Jim

someone said this is a clone MK is it true? why pots?

jesolins · Oct 03, 2009, 11:02 AM

Ken,
I suspect that they are using the pots because of the "lite" firmware they are using that is not capable of making PID adjusts. It is not a clone of the MK board. It is very different and I can see no place to mount a barometer from the photos, or the camera servo connetors. It appears to use the same ATMEGA644 processor as the MK and does have ISP pads for the processor.
Cheers,
Jim

Hi Jim,
I don't know if this is what u are asking for,but it just shows how to configure your radio.

jesolins · Oct 03, 2009, 03:09 PM

Yep, Just Tx/Rx setup info...
Cheers,
Jim

Hey i forgot to mention that i made some adjustments with the pots and made a big difference,but it sucks because the wind is blowing 20Mph and gusting to 40Mph

,but the test flights in the house seem allot better

jesolins · Oct 03, 2009, 03:15 PM

They certainly should make a difference. Be careful and do a hand flight test after each adjust to make sure it does not go spastic on you. Good to hear it is flying better

Cheers,
Jim

videos!

G-unit · Oct 03, 2009, 03:55 PM

I don't have any yet, and it is defiantly not as stable as in there videos,but i believe i have a out of balance prop,
hey do you use any of the radios trims to adjust the flying??
Thanks G

jesolins · Oct 03, 2009, 05:16 PM

Yes, you should trim so that applying power make it go straight up. Also put in -40 Expo for pitch and roll and 60% for the pitch and roll rates. Make sure you are using ACRO mode on your Tx.
Cheers,
Jim

Hi Jim, I can't located the developer's posted message on one of the Chinese Quad forum anymore. His posting apparently got deleted due to commercial contents. But I do recalled on one of his posting that he indicated the X500-D is support the native MK firmware.

jesolins · Oct 03, 2009, 09:35 PM

Hi Ken,
That would be interesting. I suppose the NAVI board or a clone could come about too..

I wonder if www.quadroufo.com would be a shop that might carry just the boards...

So many quads..so little time...

Expect a UAVX release very soon. Very good release candidate flights today between rain showers

Cheers,
Jim

Hi Jim,
Thanks you for keeping the UAVx clean with all the water.

I'm more interested on the X500 i2c ESC then the FC. I'm sure they using the HOL type ESC too.

All my fingers are ready for the next UAVx release..
