Nicely integrated, small footprint, 4 channels, a winner. Anyone testing it in a heli?

Mark, few of the heli team are already testing it on heli ( trex450) with good sucess. There is dedicated heli mailing list also,
@ Good work UFOman. Pretty congested I guess but good to go. What is the rightangle MCX connector( guessing) connected to? It that a data radio on the side of battery? Time to look for new airframe :). Keep us posted. Thanks and good luck.

Oh, its so nice to hear and see all from you !
Thanks for sharing !

I have seen @Google discussion that you faced problem of yaw oscillation due to proportional & differential gains setting for your Essystar colone.

Please share that here also because lots of people do not visit google forum.

Is this board available? I like to buy one...

Nope , but the eagle file and source is available, you can order one blank board and solder all the components. Rusty had given out the address some where, can't remember.

Ufo man,

Thank you very much for posting, its good to have this kind of information.

All,

SparkFun is planning on going into production with a version of the UAV DevBoard that is essentially the same as what Ufo man has shown in his photographs. It will have the same motherboard that is currently used, but instead of the LISY gyros, it will have the daughterboard shown in the picture, with Invensense gyros.

I expect it will go into production in a month or so. I will make an announcement when it is available.

Best regards,
Bill

Hi Bill and all. I would also like to point out that the channel assignments will be slightly different on the inputs to the A/D converter on the SF board. A modified options.h file and defines.h file is needed as well as a header file for the particular Invensys gyro config. Therefore, it is adviced to wait for the SF board. However the gains are the same and the software can use theese gyros with just some config changes. The layout and schematic has been posted to the UDB Google mailing list for those interested.

Morli: the right angle connectors (two of them, but you can only see one) are coaxial connectors for the UHF command link. The RX uses diversity reception.

Tnx, UFO , is that Thomas UHF LRS NR rx?

Comment by William Premerlani on July 7, 2010 at 12:51pm

Thanks, Ufo man,

Once the SparkFun board goes into production, we will revise the firmware so that all you need to do is select the right board in the options.h file. Right now, there are three gyro configurations that are supported, once the new one comes out, there will be 4.

Best regards,
Bill
