Many people like the unique head design of the Nine Eagles Solo Pro and Bravo SX. With the flybar on top, it gives it a unique, stable flight characteristic...yet maintain agility and does nice tight turns. So here's a simple mod. Take the Solo Pro head and shaft. Drill a hole for the shaft collar a ...

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. ...

I am working on hacking the MLP4DSM TX module into the Turnigy 9x. This will allow for Spektrum DSM2 capability so I can control my helicopters using the DSM2 protocol. I will write up a more detailed post once I get all the details worked out. I got it working this morning and I was able to bind an ...

Interesting development. It appears that in some market, the Great Wall Xieda 9958 and 9998 has rebranded cousins...Here's a couple of Nincoair Micro Evo 190 that appears to use the same canopy and parts as the Xieda 9958, which means that the canopy will fit the Xieda 9998 as well.Unfortunately, th ...

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 curve se ...

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. ...

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. ...

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 w ...

Fabricated a carbon fiber main shaft for the 9958. Here's the stock 9958 weight before and after the carbon fiber shaft upgrade.The stock weight without the battery is above. The carbon fiber upgrade 9958 is the photo below.The main motor has a lift of about 42g. So shaving a gram off the flight wei ...

Someone on the RC Groups forum wanted to know the gear ratio of the Blade mSR so they can possibly use them on another RC vehicle. I took a picture and figured I'd share here. ...
