QUADIFYRC RC Car Review and Upgrade Guides

The ​DumboRC X6PM-350 is a new, compact 6 channel transmitter from DumboRC, my favourite budget wheel/trigger radio brand. Alongside the launch of this new transmitter, DumboRC have also released a whole lot of new receivers - 8 in total. This means they have something for every application from micro to full scale, gyro, no gyro, built-in brushed ESCs and even full lighting controls for your scale rigs. In this article I'll review the radio in full and help you understand which receiver will suit you best.

DumboRC have been really successful in the budget RC area with their X4, X5 and X6 range that I covered extensively in this guide here. The reason that they were so successful is that the price was sharp but more importantly they were VERY reliably even over a long range and they offered useful features like gyro and lighting control without overcomplicating the operation of the transmitter. For these reasons we have see DumboRC radio gear get used more and more as an OEM with companies like ZD Racing and Rlaarlo.

Clearly they lack multiple model options and digital adjustments but at this price you could have separate controllers for separate cars/tanks/boats/trucks etc. The new X6PM-350 as reviewed here offers all of the benefits of the X4-6 range but in a more compact package that fits easily into a backpack plus at an even sharper price.

The Radiolink RC6GS V3 is a new trigger style transmitter and receiver combo suitable for RC cars and RC boats. Radiolink is a manufacturer that has a surprisingly long history in RC and is know for reliable control links. This particular model is a new revision for 2022. Being a mid-range transmitter it has more channels (7), is of a more premium build and has more features than budget radios. 

The Flysky Noble Pro is a new top end surface radio made by long time manufacturers Flysky. It is a premium version of the Noble NB4, which itself is a mid-high spec radio. The Noble Pro is a radio set that Flysky have thrown everything, including the kitchen sink at and I will review all of the features here so you can figure out if the may or may not be important to you - this will be the main focus of the review. Lastly I will compare against the best offerings from market leaders Futaba and Sanwa to give you a feel if they really do complete in the racing scene.

Before we get to deep into the detail (and there is a LOT with this radio) lets have a closer look at Flysky as a manufacturer. You've probably heard of them before but what you might not know is that they have been manufacturing radios for over 12 years with options in both surface (cars, boats, tanks) and air (multirotors, planes, helis). They initially started out with low to mid-range hobby grade models where their reliability was rewarded with a number of OEM contracts for various RC Cars and Boats This has allowed them to grow their manufacturing base and expand with a more recent push into the premium end of the market with the Noble NB4 and Noble Pro for surface and the Paladin and Nirvana NV14 for air. Let's have a closer look at the present Flysky offerings in the surface category:

DumboRC have a range of very similar 2.4GHz digital surface radios (for RC car and boats) with subtle differences which makes them confusing to buy. All of them around around the $30 mark which makes them extremely good value if you know how to pick the right set of features for you. In this guide/review I'll break down the differences and review the two variants that I recommend - namely the DumboRC X6 2.4G 6CH Transmitter and DumboRC X6A 2.4G 6CH Transmitter with X6FG Receiver and will of course review them and give you my recommendations.
