Someone on RC Groups mentioned that they wanted to use the low cost Xieda 9958 RX board as a replacement for the Solo Pro and Bravo SX boards. Here’s a side by side comparison photo for your modding/brainstorming purposes.

Turnigy 9x Trainer Port Resistor Mod
Update 04/27/2012 – Good news. It looks like there is no more need to cut the trace and solder in the resistor as demonstrated in this post unless you’re still running stock firmware. The latest ER9X firmware has a an option call “Enable PPMSIM” in the Radio Setup screen. It allows you to turn it […]

Module from MLP4DSM Wired Up
Here’s the module taken from the MLP4DSM transmitter that comes with E-Flite RTF kits. It shows the wiring necessary for hookup to the Turnigy 9x running custom firmware that supports the DSM2 protocol. See this post for location of the 3.3v pad to solder the red wire to. I added an LED inline with the […]

Turnigy 9x 3.3v Location
The Turnigy 9x runs internally at 5v. But it also has a 3.3v regulator on the main board that is used to power the LCD. Here are a few of the locations of the 3.3v points that you can use. Make sure whatever unit you’re connecting to that 3.3v regulator doesn’t draw too much current […]

E-Flite Blade MLP4DSM Pinout

Alternate Xieda 9958 body colors?

Unfortunately, these units are […]

Turnigy 9x – Xieda 9958 Throttle Curve
I recently purchased a Turnigy 9x and am in the process of setting up my preferred throttle curves for it. So I figure I’d share. From my understanding, being able to set your throttle curve is the benefit of setting up the initial profile as a “heli” instead of “acro”. To get to the throttle […]

MLP4DSM DSM2 Module versus Xieda 9958
The range on the Xieda 9958 isn’t that great. If you open up the transmitter, you’ll notice that there is no antenna wire connected to the 2.4ghz module. For comparision, take a look at the inside of the E-Flite MLP4DSM transmitter.

Alternative Battery Mount Location
I am currently testing out how mounting the battery lower affects the flight characteristics of the 9958. It seems like it’s improving the pivot on bank turns…but I need further testing and/or feedback from others.

New E-Flite Blade mSR X
The folks at E-Flite just released a new fix-pitched micro heli. It’s similar to the popular mSR except it’s flybarless courtesy of the AS3X Digital Flybarless system that’s already in used on the mCP X. The new mSR X is touted to be a intermediate step up from the mSR, and not a replacement. Along […]
