  1. Great mini receiver 4 Star Review

    Posted by on 7th Mar 2016

    Smallest 4 channel I have ever seem. Easy to read pin locations mounts quickly with a small Velcro pad. Great little Rx for those park flyers and any aircraft with limited space

  2. I always do busines with D. 5 Star Review

    Ive purchase from helibatics all the time, it has best prices and shipping is fast. And if you have questions always fast response.

    The FrSky products are the best.

  3. D4R-II 4 Channel Receiver Review 4 Star Review

    Posted by on 2nd Feb 2016

    This is my 3rd FRSKY receiver and it works just as well as my X8r, and X4r rx. I'm running these 2 receivers in s-bus mode. The D4r-II is great for when you want to run your aircraft in PPM, light weight, doesn't take up a lot of room, which is great for the smaller multi copters and the price is right. HeliBatic's does a great job of getting out orders in a speedy manner,I ordered my D4R-II at the beginning of the week and had it shipped to me that same week. One other point I can't leave out is the videos, which HeliBatic's provides on You/Tube are great for showing you just how to get you receiver or any item up and running.

  4. This is a great receiver! And i would be hard pressed trying to find one better! 5 Star Review

    Fr Sky 4DR-II is ahead of the curve as a small light reliable receiver. Works with popular FC's like the Naze32 and the CC3D flawlessly and easily. My next receiver will be another 4DR-II.

  5. frsky receivers 5 Star Review

    Posted by on 8th Mar 2015

    I have been using Frsky sense it hit the US market.
    In my opinion it's is the best.
    This is the 4th time I have used Helibatics and I love these guys they are great.

  6. Nice receiver... Great low cost performance option. 4 Star Review

    Posted by on 23rd Sep 2014

    FrSky D4R-II is very capable receiver with a great price point. Super small footprint, so perfect for just about any aircraft. I used it in PPM mode to get the full 8ch functionality and it worked flawlessly. The only limits are that it doesn't offer "model match" safety and failsafe.

  7. Great for Multirotors 5 Star Review

    Posted by on 7th Jul 2014

    These work great on Multirotors due to the small size and ppm output and built in telemetry.
