speedster:

about the video on the glider: is it by you? if so, could you please provide all the data on it?

same as at the other post: radio, receiver, esc, battery, motor,

thanks

Yes it's my glider

The glider is a:

Arthobby Silent 3,4 meter

**LINK**

 

And:

DX9/ Ar8000+ TM1000 and vario gauge, Mega motor (can't remember the number) and folding prop, 40 amp esc, 1800 3 cell batt.

A friend put me onto the Unisense E 3rd party sensor package. You can find the details here. If the page loads in German then I've found right click and select translate turns it into English. The package provides height, vario, as well as flight pack volts, amps, wattage, motor rpm. There is an extensive setup possible using a USB connection to a PC once you have downloaded the control programme from the site. The product can be set up in the settings function to operate with a wide range of radio equipment. I use JR DMSS and it works fine for me. Worth a look as it costs Euro 65.90 which would probably only get you one sensor from the JR catalogue!

+1 for the Unisens E sensors, I use them with my Multiplex gear and friend has one with his Futaba, English manual can be downloaded from here

Another vote for the UniSens-E - also works with Jeti.

Their UniLog 2 also works with several brands as well if you want to measure higher currents (up to 400A). With the UniLog, as well as telemetry, you also get more detail at the higher on board logging rate of 20Hz.

Soren: thank you for your help.

about your instructions on vario/altitude: tried, and have some questions:

1-the lift report shows ft/s and not sec

2-same for sink. i think this is what you meant, right?

3-when checking the screen for altitude and the other for vario, both read 'altitude'

but i hear nothing about vario. i expected to hear tones.

4-about the switch for vario: 1 position is for... tones?

5-and the other for...(i would like to hear altitude)

thanks again for your help.

regards.

You can switch of the tones on vario but not the altitude announcement when first set.

And you must move the glider up to get the tone, Normally just wave it up and down should do it.

thanks

i mean, i would like to see the several screens that show volts, mah, altitude, vario, etc.

that is, with the values at the moment.

phil alvirez15/06/2018 14:42:05

for instance: at the video, from 2:52 shows a screen with figures of what is happening at the moment.

that is what i want to learn to get.

i found the answer to my question so never mind.

Soren:

now i would like to reduce the tendency to increase angle at climb. i have this at the other radio (DX6i) but i dont know how with this. perhaps as you fly gliders too have to face same situation?

anyway, if you can provide instructions (perhaps even another tutorial) would be great.

thanks

in case i didnt make it clear: i need to lower elevator a bit when climbing by flipping a switch so the plane does not want to do a loop.

Sounds like you need to research flight modes, or perhaps a throttle/elevator mix.

it is on flight modes, right. i dont need mix. am using mode for aircraft, so it has just 1. thats all that i need.

i got into fmode,, selected a switch, and i see that when i flip it changes the number down there. great. so now what is next?

Phil your climbing under power problem has nothing to do with telemetry.
If you start a new thread for that I'm sure you'll get more answers.

Can we stay on topic here, please?

While I'm here, here's a typical telemetry screen from the OpenTx system, and yes I use telemetry a lot and find it very useful indeed, especially when a model is new.

Apart from voice call outs of various parameters like LiPo mAh used, battery volts, height etc it will alarm if signal strength is getting low, well before I lose control and likewise, warn if Rx battery is getting low.

If I really want to I can also look at graphs after a flight to see just what went on during the flight. For instance I can check how signal strength went for the whole sortie. This gives me much more confidence in the installation than a range check on the ground can. Or I can check all the individual LiPo cells to check that one wasn't dropping lower than others at any point during it's discharge.
