@SunjunKim 11 месяцев назад

3:30 Hey, you are installing the shoulder 3-pos switch in the wrong orientation. It should be rotated 90 degrees (so that the switch moves vertically, not horizontally). Check the T20 promotion images for the correct direction.

@joshuarosen6242 10 месяцев назад

That would explain why they didn't sit properly and were wedged against the component next to them.

love your product reviews...not only do you go over the features, but you go over the nuances of components and feel of materials, switches, and things that determine quality of usage. Your perspective on what is considered quality is spot on in my opinion and the details that need to be of concern are pointed out. One of my favorite reviewers and I love how you don't subscribe to hype unlike most others.

@amin0_acid310 11 месяцев назад

Nice little radio, awesome to see 1 watt, good size and lots of controls for all sorts of stuff. I guess it has internal storage for EdgeTX, I don't see a sd card slot. It has real switches, big bonus here on those. I see they have an option for Hall Sensor gimbals on their site, so it looks like there is an option to pick. Going to link this to a friend looking at an ELRS only radio, thanks for sharing! Cheers!

@crash_lander 11 месяцев назад

I believe for us FPV pilots penetration testing is lot more useful than range testing. It’s kinda odd that the two position switches on this radio flip side ways ! It should flip up and down, not side to side in my opinion. I think just turning the switches inside should fix that. Cheers and keep the air turbulent as always. Thanks for the video and the valuable review Mr. Nick.

HI Nick. Your videos are very practical and informative, congratulations. I want to ask you for advice, I already have a Taranis X9D with multiple external modules. I would like to buy a second radio to carry in my backpack in the mountains, which is more practical and easy to handle. between the Jumper T20 and the Jumper T-Pro V2, which of the two radios could you honestly recommend? I would like to use it for both drones and airplanes in mode1 and also for long range and I also wanted to ask you if it is possible to load the OpenTx firmware on the T20? Thank you.

@NickBurnsFPV 7 месяцев назад

I would expect OpenTX is compatible with both radios, I am not sure what feature OpenTX offers that EdgeTX doesn't. I think features is the primary reason fpv radio manufacturers moved to EdgeTX is how slow OpenTX moved. The T20 is a sizeable radio and based on that i think for something to be in a backpack the t-pro v2 is a better choice. With Expresslrs the control link is so good its hard for me to identify a strong use case requiring Gemini

@akshaysfpvandmtb2696 11 месяцев назад

I want to like it for the full size gimbals and being the second small radio to support the actual Lora frequencies too, but it looks so cheaply made, can't justify the price at all. Fortunately I don't have to either, I already have more radios than I can fly. Market is getting saturated now, they really have to come up with something original or at least beat the others with the price for the stuff to fly out the door.

Brother I need help Please! i have a 3.5 in quad that was working perfect until i crashed it and broke a motor. i replaced the motor but now the quad acts like i have the motor output limited to 10% . it will arm and it followes the sticks like rocking it back and forth or side to side with the sticks. i have checked everything. all is set right. but no mater how much throttle i give it it is not enough to take off from the ground. i have re flashed everything and tried older versions. checked the esc's in blhelisuit. nothing makes any difference. Do you have any idea where to start> have you ever seen this before? Please help! By the way i build quads for the public so i know what im doing. but this one has me stumped. im to the point of just randomly changing parts. i thought maybe the new motor was weak and the Fc was dumbing down the other motors to match the week one so i took it off and it still does it. it never tries to freak out or anything all seems correct.

@dragansus1 11 месяцев назад

Many are mistaken in thinking that potentiometers are worse than hall pickups! Potentiometers are just the opposite more accurate than Hall sensors. In terms of durability, I personally know people who have old Futaba transmitters that are about 10 years old and have gone through thousands of hours in the simulator. I have a 16IZ Futaba and it has 1200hrs of total run time, the potentiometers function perfectly and the zero position never shakes unlike my 2 radiomaster boxer and tx16 mk2....

@billmcdonald4335 11 месяцев назад

Your experience says pots are better. My experience says the exact opposite - twice. I had a Jumper T8SG that had terrible pots - they developed serious signal noise after only a few months of use. Same went for the pots in my current daily driver, a Radiomaster TX12. Once I installed Hall sensor-equipped AG01 Mini gimbals in the TX12, I got superior accuracy and zero signal noise. I don't doubt the durability report on the pots in your Futaba radio, but when it comes to Jumper and Radiomaster radios, it would be better to install Hall sensor gimbals in them if they don't come stock.

@vuchuong74 11 месяцев назад

Charging is fast a couple or hrs for 2500mAH 18650s. But it still only charges to 8.1 volts and not 8.4, probably for safety reasons. Every 3-4 charges (6 months? Lol) take them out and balance charge to 8.4 to ensure cell balance.

17:25 - there must be something wrong: #1 T20 has Hall sensors from the factory and it is cheaper than the #2 T20S has RDC90 sensors with potentiometers and these are more expensive. Attention: for whatever reason now the hall gimbal sensors are priced cheaper - quite the opposite how they had marketed the hall gimbal sensors on the T16S radio The T20 and T20S have only different gimbals (also looking different and I guess also adjusted differently) and there seems to be no marking on the outside if you have a T20S But your review is a T20S review, not the T20 so you might better change the title soon cause people might buy the wrong radio with the hall sensors while you were talking about the T20S with RDC90 potentiometer . Range tests are possible, just on the ground with goggles and camera. You drive away with the bike or car and watch how long the signals will cause a reaction on the rudder or flaps. Have seen some but you need a good spot maybe on the top of the roof to have line of sight for quite a long distance.

Nicks Model shows the new Hall gimbal version. The Original version has Hall gimbals from the T16/18? I expect either works fine.
