RE: SUCCESS! - A Brushless DF Conversion
Hi Rusty
Please find Mike Dammar answer regarding to the motor problem.
Do your boards have a small black capacitor on the bottom of the PCB near the front the board on the 9 pin connector that attaches the vertical board?
That, and new capacitors on the motors should take care of it.
You should be able to copy the part position from one board to the other.
The part is a 68 UF 6.3 volt tantalum capacitor, make sure the polarity is correct
You can use a larger or slightly smaller capacitance, or a larger voltage part. A throughole part might be easier to come buy as well.
Have a great weekend

RE: SUCCESS! - A Brushless DF Conversion
Hi, all
Before CUTTING the pin of the old board for the BL modification with Berg RX, I want to ask if there is a way to 'disable' on-board RX. If I can disable on-board RX without damaging the board, and can feed PPM signal from the modified Berg into the 5th pin of the horizontal board or 9th pin of the vertical to horizontal board, I think I can easily return to the original brush motors without Spectrosolution's knowledge.
Another question is; As far as I can find PPM signals from RXs, can I use any RXs with more than 4 channels?

By the way, if you have the DF with the BERG receiver, why not just unplug and remove the receiver? You could even insert a pin with the new Receiver PPM signal into the socket so that there is no modification to the board.

I have old board and I'm going to modify with separate 72Mhz Berg receiver and/or 40Mhz receivers from which PPM signals can be fed. (We can use both 72Mhz and 40Mhz in Korea.)

@13BRV3 Are you using your Futaba 2.4GHz mod with your UAVP? Do you have any updates with your mod...changes etc? I believe you're using 5 channels becuase the 6th pulse wouldn't cooperate. Lastly if possible, please explain how and where you installed the nand gate chip. Sorry for all the questions and thanks for your input.

Are you using your Futaba 2.4GHz mod with your UAVP?
One of the UAVP developers has written a beta version of the flight software that can use PPM inputs, inverted or not. This may allow some of the non-standard receivers to work, IF you can get a PPM signal out of them. With my modded Futaba receivers, I could use the PPM or not, but there's no advantage to using PPM, so I'll stick with the normal way.

Mike,
Don't know if you checked out leaf rake tines for landing gear yet I found this post at the xufo forum. Here: http://forum.xufo.net/bb/viewtopic.php?t=7797 Sounds like the landing gear you were interested in was welding steel wire.
Cheers,
Jim

RE: SUCCESS! - A Brushless DF Conversion
Hi, Mike
I am trying to contact you on this thread as the other thread seems to have died - I sent a private message with no success and wondered if everything is OK - it obviously is!-
A much simpler question (for now) I wanted to know the dimensions of the new board as I am building the frame ready for the new board from Mike Dammar - if you could let me know these I would appreciate it
Thanks again
Ted

Check the other thread again. Since no one was asking questions, it fell back to page 4. It should be near the front now.

RE: SUCCESS! - A Brushless DF Conversion
I have a 2410-08 which worked on the last plane I put it on... and now I'm having a heck of a time setting up the ESC which is a Tower Pro Mag 8 18amp (the same one which was working!) I just moved the ESC and the motor over to new plane. I get beeps etc. but now the prop just rocks back and forth...
Any lay-mans terms instructions? I think I have the degrees off and i don't know what they should be...
3 degrees, 8, 15 or 30 degrees... ?
any suggestions?
Thanks,
Rod

Old Man Mike ,
Do you think this mode will work with the X-3d quadro with the chinaboard i,, the receiver is also integrated in the board
Thank you very much

RE: SUCCESS! - A Brushless DF Conversion
Hi Woorie,
They fly great! Mike Dammer has offered a new $375 experimental board for brushless and will mod last generation boards that can be identified by the 12 holes in the front for where the connectors for the ESC's will be installed for $55. Those fly great too, much better than the brushed versions!

RE: SUCCESS! - A Brushless DF Conversion
I want to know whether someone who converted to Old Man Mike's method with their standard DF frame, optocouplers, TP 2410-09, 1045 props, etc..., are still enjoying their DFs.
There were sensitivity issues about gyros for larger and standard DF frames last Autumn in this forum but there seems no solutions yet.
I don't want to buy DF board for brushless motors, but want to use standard board to convert ...
In short, direct drive BL conversion on standard DF frame and standard board do not suffer from oscillation?

RE: SUCCESS! - A Brushless DF Conversion
Guess I wasn't clear enough...yes I did the OMM BL opti-mod...it still flys great. Go to the link above for much more info. Many of us in that forum did this mod and then moved on to the experimental BL DF board that I also mentioned above. I also did a mod to add a 100k pot to the nick and roll gyros for even more stabilization and no continuous oscillations. Here: http://www.rcgroups.com/forums/showp...&postcount=941

RE: SUCCESS! - A Brushless DF Conversion
okay here is a detailed Power point version of the OMM Opto isolator brushless conversion mod applied to the Chinaboard / X-base (X-3d quad) by Jesolins
This diagram was revised by Jesolins and approved
I hope it helps anyone who wants to go brushless at an affordable price just like me hehe
Thank you very much Jesolins for your support and for revising the diagram
and of course Thank you very much Old Man Mike for making my dream come true by offering an affordable brushless solution

Great job! Please keep us posted.
I don't understand why Draganflyer designers haven't come up with something, since the X-UFO and other European quadrotors are brushless. I've been waiting for some annoucements from the DF guys, but I guess they have no incentive to upgrade their system - darn lack of competition...
