Same thin here. Bought one while on backstock and canceled my order after a while because sick of waiting.
thought i give it another try a month ago since 20 people ordered already but no luck until now.
if you need it truely it would recommend to search and buy it in your local rc store rather than wasting time here.
Ok. I have been patiently waiting for my order to be filled with this item since 11/27/12. Any idea when I can expect to receive what I have already paid for LONG ago??? I realize HK may be at the mercy of the manufacture, but the backorder status of this item has been ridiculous. Thanks.
Hey all, my tester is great but the LED display is quite dim, I've tried new AAA batteries, also running off DC supply, also 6.0v battery pack, no change in brightness. Question is, is there and adjustment of some sort (pot) to make brighter and has any one else had the same issue ?
Yeah... I tried using the RPM sensor outside once ('cuz they don't work well under Flourescent lights - darn CFL's *-) and couldn't even see the readout!
The only recourse I've found is a ballcap and shading the display. :-(
If you find a better answer post it here. :-}
There's no way to tune a conventional servo from the outside. You can vary its throw & thus its centre by changing the factory determined limiting resistors in series with the feedback pot. Increasing the resistance increases the servo throw or degree of rotation. Tuning the centre as you call it, would be a cumbersome exercise by this method & scarcely worth it. Unless you're confident to achieve the correct outcome, you're better off leaving it. It's very easy to ruin a servo from within. The
I've just attempted to upload detailed instructions for you, but it failed & I lost the whole thing myself. To avoid writing it all again, I'll just give some basics. Select F4 and the ESC will be controlled by the knob on the front panel. The MT-1 should default to F1 when you switch on. Press the UP button a few times until F4 is displayed, then press MOD. You will then be in F4 mode. The motor should be off completely when it reads 1000 and fully on at 2000. Beware if your ESC has a BEC. If i
Got one Turnigy tester already which will not shows the pulse width in micro second (uS) and will not step in ONE uS. So spend the money to get one of this GWS MT1 servo tester which can step 1us between 1000us to 2000us. I use the MT1 to test all my spare servos on-hand. I put a 2 feet thin carbon fiber wire on top of each servo arm and advance the tester by 1 us at a time. Yes 1 us. I count the steps could observed from the cf on arm. I record the steps between 1000us to 1500us and then to 2000us. Here are the result to share. Plays is the level of free movement I can push on the servo arm. 0 is almost no plays and 5 is highest plays, may be 5 degrees.
CS929MG left 89, right 81 total 170 steps = 5.8us dead band Plays=2 BA0361 left 79, right 71 total 150 steps = 6.7us dead band Plays=2 HXT900 left101, right100 total 201 steps = 5us dead band Plays=1 HextMG14 left109, right106 total 215 steps= 4.6us dead band Plays=0 TPMG995 left106, right120 total 226 steps= 4.4us dead band Plays=5 HXT500 left 132, right129 total 261 steps= 3.8us dead band Plays=3
So the CS929MG would has a 6us dead band, with medium level of play on free movement. Not surprise me that the small BA0361has highest dead band because of the smallest size on resistor pot. The favor HXT900 has 5us dead band and less play, not bad. I found the Hextronik MG14 the best on play and good on dead band too. The TowerPro 995 has too much play on gears, but it has the most constant motor advanc per each 4~5 us.
Would it be possible to use this device to use/test an ESC itself? I'm needing to manually/directly control a brushless esc and motor setup without the use of my radio tx/rx and am having trouble finding something that works.
I don't know what you're trying that's not working, but the GWS tester will do this job nicely. You can use the F2 set up to set the steps that suit your purpose. First set the time step amount via the F0 3 function, then go to the F2 & press the UP button to advance the speed or the DOWN to return to low. Another method is to select the F4 instead of F2 and use the knob to control it. The speed will change as quickly as you turn the knob. This is probably the safest method as you may have to de
This is a very nice little unit for the price but it does have some limitations.
I normally make my own equipment but you can't purchase the display unit for the price of this complete tester.
To answer the question, this tester will not measure the servo current draw that's about the only thing it doesn't do.
To measure the current taken by the servo you require a scope which is fitted with a current probe in the servos power feed line.
Normal meters either analogue or digital are not up to the task of measuring the quick rise of current when a servo starts or changes direction.
Despite this limitation I find this tester very convenient for testing and setting up servos and for the price you can't go wrong.
Very easy to check how many pulse required for a certain servo to be in center position.Then you measure the pulse output from the rx. and adjust the subtrim to get the pulse value.Your servo will be perfectly centred.Also useful to check pulse required to trigger the ESC.Very convenience to use.

Other modes are: F1: low / mid / high by 3 different buttons F2: up/down the range with steps (see F0-3) to check sensitivity of servo F3: continuous / endless low to high travel with 6 selectable speeds F4: manual travel with knob (add a "0" to read puls width) F5: read puls width on a receiver channel F6: read puls width from TX (needs extra cable). Really good device, but needs some reading and understanding before use.

Just in case you were wondering, the photo is already updated. Excellent professional tester. My *only* complaint is that the selected function is shown as "F1", "F2", etc. - not exactly something that I remember easily. However, everything else is utterly perfect: It can run on batteries or external power, the batteries are replaceable AAAs, the offered functionality puts much higher priced units to shame. This is a steal for this price!

This MT-1 is a very useful testing device for servos, receivers, and transmitters. Easy to use. Well worth the price. I am looking for the Futaba transmitter cable to complete the over-all testing capability.

Great servo tester and rpm measuring device. Perfect to see how your servo performs and nutralizing before installing in a model without settingup your RC equipment. Possible to use on batteries or adapter (cable included). Manual included. Musthave for every r/c hobbyist.
