LATEST MODS

I am going to hack another module into the Devo7e running the DeviationX firmware. This nRF24L01 module will allows me to run WLToys new protocol, HiSky and a host of others. It has the PowerAmp circuit for longest range. See this protocols spreadsheet for more info.

Here’s the schematic:

And here is how I wire it up to the Devo7e.

Keep in mind, there are two locations you can connect the CSN (yellow) point to on the Devo7e. Either to TMS or TCK. If this will be the first addon module you install into your Devo7e, then connect to the TMS location. If there’s already a module installed, then you will use the second point: TCK.

Then put your Devo 7e into USB mode, connect to computer and open up the drive. Locate hardware.ini (tx.ini on older firmware). Enable the newly installed module so that the radio recognize that the module has been installed and remove the * from the protocol selection box. (Remove the semicolon that proceeds the line to enable it.)

If you installed to the TMS location, then A13 is what you need to type in.


enable-nrf24l01 = A13
has_pa-nrf24l01 = 1


If this is your second addon module and you installed it to the TCK location, then A14 is what you need to type in.

enable-nrf24l01 = A14
has_pa-nrf24l01 = 1


Check with the DeviationX manual for more info. Hope this helps.

Someone on RCG wanted photos of the two 80-class CP heli, so I took these quick photos for reference.

In photography, the object closest to the lense generally looks larger. Despite that position, the photo of the HCP80 (aka FBL80) still shows that it’s a slightly more compact heli overall. Both are about the same height.

About the same rotor span distance.

The HCP80 is not as long. Without the canopy, both HCP80 and Nano CPX are almost the same length. The Nano CPX has a slightly longer tail boom.

Not much parts are compatible or interchangeable between the two. Only the tail motor would work perfectly. 6mm x 15mm CCW. So the HCP80 tail motor would be an ideal replacement for the Blade Nano CPX.

Just sharing a discharge curve I just grabbed while cycling the new Hyperion 550mAh and Glacier 600mAh cells. Interesting result.

I’ll discharge at 2A to 3.7v at a later time to see how well the cells really stack up.

Preliminary results.

Helifreak user Ian99 made available a beautifully rendition of the Mikado Logo XXtreme. His interpretation into a paper model looks great. I wanted a different color scheme and wanted to be able to use my Silhouette SD machine to cut it out for me…so I vectorized it.

Here’s the first draft of the red/white version.

Ian99 also details his tips on how to put together a good looking paper canopy. Have a look here: http://www.helifreak.com/showpost.php?p=4963926&postcount=199

I have some of my own thoughts here: http://www.rcgroups.com/forums/showthread.php?t=1696633

Using Staples brochure paper, the prints are respectable and the weight savings is noticeable over the photo paper version. Finish canopy comes in at 1.55g. About the weight of the stock Nano CPX canopy. :)
