From the January 2020 Midwest RC Monitor By Ken Myers
There were 16 members present at the Wednesday, January 8, 2020 meeting during Ken's Jumper T16 preview presentation. Ken Myers' presentation was about a fairly new, Feb. 2019, RC transmitter known as the Jumper T16. It is able to transmit using a large number of 2.4GHz protocols and therefore, it is compatible with many different brands of 2.4GHz receivers. 1. How many of you are regularly flying with these 2.4GHz radios?
1. the RTF transmitter that came with your aircraft: 0
2. How many of you are currently flying 2.4GHz with more than one of the brands mentioned?
3. How many of you are flying a module in your main Tx to use a different protocol than the one the main transmitter is using?
4. How many of you are using a multi-protocol module, like the Jumper JP4IN1or the iRangeX IRX4, in your transmitter?
Dave Stacer helped Ken demonstrate how he could control 6 different aircraft, one at a time, using the Jumper T16 transmitter with very different 2.4GHz protocols. The six aircraft, set up with six different protocol receivers, were an RUA 2-4-10 with a FlySky iA6B receiver, a stick-type plane with a Tactic TR624 single antenna receiver, an E-Flite BNF Archer with a DSMX receiver, a SuperEZ with a Tactic TR625 dual antenna receiver, another RUA 2-4-10 with a Jumper X8 receiver, and a Pandora with a FrSky X8R receiver. Two important things that he noted were that the two Tactic receivers use different protocols and that the Jumper X8 and FrSky X8R use the same protocol. After the demonstration, he asked the members a few more questions. 1. How many of you have heard of a transmitter operating system known as OpenTX? 6 2. How many of you have heard that OpenTX is too hard to learn and program a plane with? 0 3. How many of you have heard that OpenTX is only for multi-rotor pilots and computer geeks? 0 Dave was also volunteered to program a plane on the Jumper T16. He had never seen, or held, that radio before. Ken talked him through the steps of how to turn on the transmitter and create a new model. Dave read the onscreen question prompts and Ken told him how to enter his choices. The guidance questions appeared to be simple to answer.  Screen 1: Choose between Glider or Plane
 Screen 2: Does your model have a motor?
 Screen 3: Number of ailerons on your model? Choices: Two One, or two with a Y cable None Chosen: One, or two with a Y cable  Screen 4: Does your model have flaps?
 Screen 5: Pick the tail config of your model.
 Screen 6:
 Screen 7:
 After pressing the RTN button, the model select screen appears. The newly created model could have a name added and its protocol set to become active for a plane as well as other options. For brevity, how to finish the setup was not demonstrated at the meeting, but it truly is simple. The Jumper T16 was 1st advertised by Banggood in Feb. 2019. Features include:
There are only a few sellers of the T16 in US. Grayson Hobby $159.99
Addendum 1: 01/12/2020
Heli-Nation $169.99
Updated Supplier list, Jan. 10, 2020 Team BlackSheep $159.99 DefianceRC $169.99 Free shipping BuddyRC $159.95 NewBeeDrone $169.99 Ken gave the members a warning about the 18650 Lithium Ion cells being supplied by Grayson Hobby. They are branded as Garberiel and listed with a capacity of 6000mAh. Ken tested them and found their capacity to be only 850mAh when discharged at 1/10 the capacity of 6000mAh. In other words, they were discharged at 0.6A. Ken recommended the 18650batterystore.com online store as a source. The LGs that he purchased from that Website are no longer available, but there are good Samsung and Panasonic cells there. They do not need to be high discharge types as the system only draws 350mA. Another good source is www.rcbatterykit.com. Bob can supply the cells, wiring for internal charging and a charger at a very reasonable price. The price depends on the options that you choose for the cells and whether or not you’ll purchase a charger. The Jumper R8 receiver seems fine, but Ken had not flown it yet, and at $9.99 when purchased with the T16, that's a savings of $5 over the regular price of $14.99. They also offer 2 Jumper R8 receivers for $11.99 each. There are four active threads on RC Groups regarding Jumper.Three are about the transmitter and one about the Jumper R8 receiver. Jumper T16 2.4G 16CH OpenTX Multi-protocol Radio (started Feb 2019) Jumper T16 Owner's Thread - (2.4G 16CH OpenTX Multi-protocol Radio) (started May 2019) Jumper T16 hardware hacks (started June 10, 2019) There is also a RC Groups thread regarding the multi-protocol module.
Ken also told the members about a supposed new radio that is based on the Jumper T16. It is called the RadioMaster by Hobby Porter. The person that started Hobby Porter worked for and with Jumper, so it is basically a Jumper T16 with a few upgrades that that person thought would make it better. It is not available at this time.
A list of the supported protocols for the multi-protocol module can be found on github. He also noted that there is no protocol for the Futaba FASST receivers only the SFHSS is supported. The radio does not come with a manual. Jumper has a manual online at jumper.xyz. The manual is dated Aug. 2019, and Ken did not find it all that useful. To help him learn more about the Jumper T16, he created a Website with links to all of the useful YouTube video about the Jumper T16 and OpenTX. Ken posted a link to that collection of YouTube videos on the homepage of our Website. He noted that the link is currently active, so that the members can learn more about this transmitter. The videos are arranged by date with the newest first in each section. 1. OpenTX Companion Computer Software & Jumper T16 Firmware Updating for the transmitter's OS, the Multi-module's firmware & the SD Card
Ken called for questions from the members. Some of the questions and Ken's answers follow. Is the transmitter FCC part 15 certified?
https://fccid.io/2ANTI-T16 Is this going to become your daily transmitter?
Addendum 02/04/2020 The Jumper T16 was bound a QIFENG QF008 Boeing 787 using the V911S protocol and flown at the Ultimate Soccer Arenas in Pontiac, MI. The plane was very pitch sensitive, but the radio worked well. There were no problems in this RF rich environment. Addendum 02/05/2020 The Jumper T16 and QIFENG QF008 Boeing 787 was flown six times at the Legacy Center in Brighton, MI. Dual triple rates had been set up on the Jumper T16 and the plane was dialed in and flew very well. Again, there were no problems in the RF rich environment. |
