    Repair non-connecting v911 5-in-1 RX

    Every now and then, I see a flurry of post about v911 RX that refuses to reconnect or rebind to the transmitter. Often times, this occurs following a crash. The symptom is upon plugging in the battery, the RX LED immediately turns solid without blinking, or sometimes, it does a series of rapid blink and […]

  • Evolution of the mSR X Brushless Mount

    Just wanted to share the evolution of my mSR X brushless mount. I find it’s easier to design on the computer. A digital caliper is a great tool to transfer the measurements into your graphics program. A CAD program is ideal. I am more familiar with Illustrator, so that is what I used. If you […]

    Hobby King’s XP 3A Brushless ESC

    For those looking to upgrade the MOSFET on the XP 3A, here are the location of the N-Fets and P-Fets. You can replace the N-FET with the DMN2041. This takes the resistance of the original FETs from approximately 30 mOhms down to 26 mOhms or even 13 mOhm stacked as mentioned below. The P-FET can […]

  • Brushed Main Motor Micro Heli

    Brushed Main Motor Micro Heli

    Looking at the three motors I happen to have apart, I noticed the winding is so different between them. The Xieda 9958 version 2 motor, the v911 and the mSR are all slightly different. I don’t know how this relates to the power these brushed motor is able to produce. Anybody know? I saw that […]

    E-Flite 150mAh 25c 1s LiPo Test

    I finally got a hold of the new EFlite 150mAh 25c LiPo. I was curious about this cell because a Horizon Hobby employee said that the chemistry is better than their prior 1s cells. One person on the forum noticed that the head speed of their mSR X has a higher pitch, which suggest it […]

  • v911 Main Gear Alternatives

    I was given a Xtreme Productions delrin main gear for the Solo Pro. So I took the weight differences between the v911, Solo Pro and Xtreme. The v911 is the lightest, and very slightly thinner than the other two. Here’s the weight of the stock v911 main shaft compared to the Solo Pro’s carbon fiber […]

    v911 Battery Tray Adapter

    WL Toy’s v911 is a fun micro RC helicopter. But because of it’s unique battery connection, you are limited to the factory 120mAh LiPo or recently released 130mAh LiPo. Here’s a mod that takes the battery connector part and turn it into a battery tray so that you can use the popular 1s LiPo with […]
