The Jumper T14 is the corporate’s third radio controller reviewed right here on FirstQuadcotper. The T14 is a mid-level transmitter with a built-in 1W ERLS module. It adopts RadioMaster Boxer and TBS Mambo-like type, issue, and format. Not every little thing in regards to the T14 is whoa-inducing; it lacks flight mode buttons, and the antenna just isn’t detachable for improve functions.
JumperRC launched the T14 with two gimbal variations and three ExpressLRS frequency choices (868MHz, 915MHz, and a pair of.4GHz). The worth distinction between customary Corridor sensor gimbals and CNC gimbals is about 30 bucks. It isn’t a foul deal, contemplating {that a} pair of RDC90 gimbals is $59.99. The radio controller might be the longest-lasting element within the backpack of an FPV drone pilot, so it’s value selecting one that won’t solely fulfill all of your technical wants however be snug to make use of, and also you’ll additionally like the way it seems to be.
Like most related radios, the Jumper T14 additionally runs on EdgeTX, most likely the most well-liked open-source firmware for distant management transmitters. As an alternative of an exterior micro SD slot, it has an onboard 512MB flash reminiscence to retailer system information, voice prompts, and radio backups (you’ll be able to retailer as much as 60 fashions).
Jumper T14 radio controller evaluation
Disclosure: I acquired this FPV radio controller from JumperRC to check it and do an in-depth evaluation. Though the RC was provided totally free, all opinions on this article stay my very own, with no affect from my accomplice.
Just like the T20 Gemini, the brand new T14 additionally is available in a pleasant purse with the next equipment: a neck strap, USB-C datacharging cable, and spare pressure springs. Moreover, JumperRC features a shoulder swap improve package.
The carry bag has a meshed inside pocket for the small equipment and a velcro band that secures the radio contained in the case. The gimbals are protected with some primary foam cylinders.
Like its contenders (Boxer and Tango), the Jumper T14 additionally has a field type issue with an approximate dimension of 185*175*79mm. With out batteries, the transmitter weighs roughly 500 grams. On the again is a cheapy plastic foldable handler and a normal JR extension bay. The deal with complicates issues a bit while you load an exterior module. You possibly can add compatibility with TBS Crossfire receivers and even toy drone receivers via the JR bay with none points.
It has anti-slip rubber inserts on the again to supply a great grip. Holding it feels snug; all of the controls are simply accessible no matter whether or not you’re a thumber or a hybrid pincher.
I just like the T14 Jumper’s foldable and rotatable antenna. It makes the radio packable and permits it to match the RX’s antenna place (horizontal/vertical) for the perfect sign energy. The antenna is related on to the RF board, so upgrading to a 2.4 GHz ELRS MOXON directional antenna can be difficult (you have to disassemble your entire radio).
On high, between the Sort-C port for firmware updates, knowledge switch, and FPV simulators and the three.5mm coach port, there’s a tiny sunken button with an unknown objective.
My evaluation unit got here with the silver RDC90 gimbals. Within the video under, you’ll be able to see the best way to regulate stick journey distances and stick top. Sadly, you have to take away the radio’s entrance panel to regulate the gimbal pressure. Three spare springs are included (in case you lose it).
Jumper T14: Battery choices, charging, and dealing time
The T14 may be powered from 6.0V to eight.4V. Natively, it’s supposed for use with two 21700 LIION batteries. Because the 18650 cells are 5mm shorter than the 21700, you must carry the battery contacts nearer collectively while you use one of these battery(scale back the space between optimistic and destructive results in maintain the battery securely).
After testing it for an entire day, I cost it again through the USB-C port utilizing a 5V/5A charger. From virtually zero (3V/cell) to full, it took round 3 hours for 3000mAh cells, that means it has about 10W of charging energy.
Caring in regards to the well being danger it could trigger, I’m afraid to make use of any radio machine over 500 mW near my physique, so I set the T-14 to 500 mW (half its max energy) with dynamic energy enabled -this energy setting allowed me about 4-5 hours of working time.
Jumper T14: Switches/Rotary knobs/Trims
The Jumper T14 is meant for FPV pilots who don’t want all kinds of management choices. On the entrance panel are 4 switches, one 2-position and one 3-position swap on every nook (SA, SC, SD, and SR). Within the center, proper above the speaker, are two rotatory knobs (S1 and S2) with a middle indent. There are not any devoted flight mode buttons, simply two mini 4D joysticks for trimming.
Out of the field, it comes with two low-profile, button-style shoulder switches. The left is a latching (on/off) swap, and the fitting is a momentary one. Jumper-RC features a modification package for those who favor the basic stick-style steel switches as a substitute of these push buttons (see picture under).
Jumper T14: Display screen, Controls, Standing LEDs and Menus
I beloved T14’s massive display screen from the primary energy ON. Lastly, JumperRC realized that dimension issues; each of my Jumper transmitters have a tiny display screen that’s tough to learn for individuals previous the prime of youth like me.
The Energy button with the Jumper emblem is near the middle of the RC, positioned between the speaker and neck strap hook. The standing LED is moved from the on/off swap to the edges of the two.4″ monochrome OLED display screen.
If in case you have ever used a Jumper radio, navigating the T14’s menu can be easy, due to a normal management format with a scroll wheel and three buttons (SYS, Web page, and RTN). You possibly can enter into radio setting pages by brief the “Sys” button, and by lengthy urgent, you’ll be able to entry the ELRS LUA script interface.

Pricing, availability, and choices
As talked about firstly of my evaluation, the T14 radio has two sorts of gimbals (HALL and CNC) and three ELRS frequency choices (2.4GHz / 915MHz / 868MHz). The Jumper T14 is out there to order from February 2024 at many well-liked RC retailers, together with NewBeeDrone and Banggood, and platforms like Amazon and Aliexpress. The mannequin with CNC gimbal proven on this evaluation is priced at $109.99. A suitable clear case is out there for 16 bucks.
Jumper T14: Person expertise and efficiency
Regardless of its compact dimension, the T14 is a flexible and absolutely succesful EdgeTX transmitter. The quick 10W USB charging is welcomed for individuals who fly quite a bit. With restricted management choices, the Jumper T14 is an effective selection for FPV drones, easier gliders, and drone simulators.
ExpressLRS is thought for its glorious efficiency and long-range capabilities. The utmost flight distance document at 500mW@50Hz is 11.47 km. When you prioritize responsiveness and latency, the T14’s built-in ELRS TX helps as much as a 1000Hz bundle charge.
I examined the Jumper T14’s efficiency utilizing my long-range Chimera 9 ECO drone outfitted with a SuperD ELRS 2.4G receiver and DJI O3 Air Unit. I had a steady radio sign on your entire FPV vary. I ought to point out that the T14 just isn’t suitable with ELRS Gemini (true range twin channel transmission), because it solely has one RF module.
Throughout use, I don’t significantly recognize that the cooling fan begins even on the lowest energy setting (25 mW), making the radio noisy. I favor having fun with the sound of nature, particularly within the spring when the birds are chirping.
Jumper T14 vs Jumper T20 Gemini
When selecting between the T14 and T20G, take into account the T14’s advantages, together with an even bigger OLED display screen, the aptitude to help exterior modules immediately with out requiring an adapter, and its pleasant price ticket. Then again, for those who prioritize the compact type issue, extra dependable ELRS communication, and the variety of controls, the T20G might be a greater choice for you. Within the desk under, I in contrast a very powerful specs of those two radios.

Jumper T14 options: RadioMaster Boxer and TBS Mambo
The Jumper T14 reassembles the RadioMaster Boxer’s design in lots of features. It has the identical sq. form with a comparable format and association of switches. The TBS Mambo additionally shares an identical design and functionalities. Each the Mambo and Boxer have a beginning value of $139.9, making them dearer than the T14.
