Let's see your 200's!


Recommended Posts

Wiring was mercifully very simple.  The battery sled has the middle tab exposed on top to add a wire for the tap.  I used a piece of wirewrap wire threaded behind the battery sled to connect that tap to the DNA 200 (hope it's thick enough -- that's all that would fit -- all it carries is a bit of balancing current so should be OK).  

Using the existing up / down buttons was also easy once I figured out how to support the little daughter board with the original mother board removed. The existing buttons use a common return path but that's OK because the up- and down- are common on the DNA 200.

Making the fire bar work properly and fit exactly back where it was as stock was a project.  The trick was a lot of milling of the original plastic sled and fabricating little supports for the board.  The existing fire bar setup pressed two buttons mounted down the middle of the original motherboard.  The whole fire bar assembly originally mounted through two holes in the middle of the motherboard.  Uh oh, DNA 200 doesn't have two holes down its middle and doesn't have two fire switches where they belong either.  The entire assembly had to be "re-engineered" to fit, to move and to press the DNA 200 fire button but not press on anything else.

Installing the VT 510 was also a little involved.  The external threads weren't long enough so the underneath area of the xcube top plate had to be milled out.

To sum up, if I had it to do over again, this would not have been my first choice for a retrofit.  It was a lot of work. Now that it actually works, it was worth it lol.

This one is 2s with 2 x 1000mah lipo's

Now that is machinist porn lol. What tools/machines did you use? Looks like every little detail finished to nth degree. Beautiful.[/QUOTE] Thanks Mad Scientist. My missus bought me a Proxxon micro mill last year for my birthday last year and it stopped working just after this birthday. I used this years birthday funds to buy a swig 1XL mill/drill and it's been great. I also use a dremel and needle files to finish off.

I have to see if Santa might be willing to spring for something that expensive lol. Your experience shines through though. I am no expert machinist but I know enough to know that ain't easy.
