This is the Radiopost TS401 G2 2.4GHz DSSS Radio system, with a RP24RA5DX receiver. The TS401 radio is one of the most advanced 2.4GHz radio systems available, and delivers comfort and incredible performance. The TS401 introduces the first ever swivel color screen and built in internal antenna combined with proprietary 2.4GHz Signal Direct Sequence (SDSTM) technology bringing a powerful direct signal to your car or boat. This technology enables the user to have direct control of their vehicle making every movement of the throttle and steering wheel incredibly accurate. The 5.5ms frame rate balances both performance and consistency. No artificial accelerated programs are used.

With a strong focus on ergonomics, the TS401 is naturally balanced, with a 50/50 weight distribution from top to bottom. Radiopost SDS systems use considerably less power, allowing the use of a smaller battery which helps to reduce the overall weight of the radio. The control wheel can be switched from right-hand to left-hand with only 4 screws. Plus, the software was developed with both beginners and serious users in mind, providing all the functions you need. Easy to navigate buttons and a color screen all provide a user experience not found in any other 2.4GHz system.

Small and incredibly light weight Radiopost 5-Channel receivers deliver a high performance package that can be used for many applications. They use Quick Sync (QSTM) technology and deliver high resolution data without diminishing speed and precision of the transmitter. The receivers are durable and proven to work under various temperatures and conditions.

Radiopost TS401 G2 2.4GHz DSSS Radio System w/RP24RA5DX Receiver
I've had the radio for about three and a half years now and have been pretty happy. The menus are pretty easy to read and there are tons of options for any function you could want. The screen can be hard to read in direct sunlight which has been one of my biggest complaints with the radio. The other issue I have is that the radio is quite heavy and I find myself holding lower and lower during nitro mains over 15 minutes. Functionally, it has been flawless the entire time I've owned it, no glitches, no bind issues, no problems what so ever. If it was about 100 grams lighter I'd be keeping it but I've started looking for a replacement.)
