Thanks to mstrens and his openxsensor https://openxsensor.github.io/ project and Marc ricci for the flight instruments lua script,
I built this for around £15 .
Vario tones much improved over none IMU vario.
Connects to either hub or s.port rxs.
I will discuss the building here and upload the code for both as its slightly modified for this purpose.
Note the display will not show inverted flight but to me that does not matter.
lua script telem2.zip
Note this is working on opentx 2.0.17 which I am running on my taranis, I have not altered it for 2.1 but it could be altered I imagine by just changing the telemetry names, if anyone wants to do this and check it works on 2.1 then I can post their version here here if wanted.
OK I took the plung and ordered a new dlg, a thowt by ondrej http://www.rcgliders.cz/letadla/thowt-f3k/
After scruffy bought one and showed it off I thought it looked well worth the money and should fly better then the blaster.
It will be my first dlg build as the blasters were both second hand.
Ondrej is making it as I type this hopefully and I will update once it arrives.
I will have to decide on how to install servos etc and will watch scruffys build with interest!
Got my HK minimoa up in the clouds with a keychain camera on, lost sight in the clouds at 1300ft so a spin down was needed , makes me want to try fpv!
UK laws limit power from fpv txs so might not get great range.
After flying planes and then powered gliders I bought a second hand blaster dlg, a bit beat up but flyable if a bit heavy. I then got a new one and put sd150 servos in it which burnt out after 3 months, I replaced them with hxt900 which worked well but were a bit big , I since replaced them with Corona DS633BP which have worked fine ever since and change from 2 cell lipo to one cell which gives a good 5 hours flying time.
Struggling with launch heights due to bad back but thermalling is amazing compared to my foam gliders.
Relights were next to impossible with the dx6i, having to put the throttle stick back up from bottom to top, reset timer and flick the flap switch while spinning round ready to throw the thing again.
With the Taranis I programmed it all to work with one momentary switch, which does everything including telling me my flight time and my launch height!
No competitions round here but I do compete online with buddies all over the world and in the UK for longest flights in a given period.
Last year I got an early version of the frsky taranis and having had a spektrum dx6i for about 5 years was at first a bit daunted but soon got to grips with it and absolutely love it.
I soon bought 3 varios 4 rxs for my gliders and a module to make it work with my dsm2 rxs for my powered stuff that does not need telemetry.
Now await I the new version of open tx with new progrqmming to learn it should be fun.
Updated now to opentx 2.0, blaster dlg needed some repramming and few custom switches wrong on a couple,of other models and now all is working again, vario tones are different, cannot get a dead zone with no beeps but beeps can be tuned in their pitch so have made them lower and more bearable.
Can back up entire radio and settings to and from SD card now which might come in handy if I make a really big mess lol.
OK so here's my blog for my phoenix 2000 kit from hobby king.
Motor kDa 22 http://www.giantshark.co.uk/product/...ushless-motor-
50 amp esc from HK
Hxt900 on elev rudder and flaps.
Cheap digital white servos from HK on ailerons.
Battery I use 4 cell lifepo4 a123 1100mah home made packs weighing 173g.
Stock prop and spinner give good performance 15 seconds to about 500ft and I use 2 mins of power total using about 660mah giving me enough to spare for gliding around for a good hour or more.
A bit of tape over some of the compressed foam hinges was needed.
A rubber band secures the hatch just in case it pops off like some have said.
Push rods and clevises seem all good though some have had them break in the past the ones in my kit seemed very good, I did just put some heat shrink around ends to keep them from opening.
Flights are very good with 15mins dead air which is not much but not using much mah with my lifepo4 option compared to a lipo of say 1800mah which would give mo like 40 mins dead air.
However most times I go out I thermal and get 20 to 30 mins easily, and often more.
A number of times I have got over an hour.
I have 3 other simiiar gliders ie 2 metre foam wings,
Ask21, asw28 and minimoa, they all fly nice in their own way but the phoenix is the best all rounder having good speed good thermalling ability aerobatic performance and can be slowed down with crow braking for landing making it easy in all conditions to fly and land.
Realised I don't really use this blog so thought I would update it,
OK been flying for about 6 years now after a long break.
Electric made that possible and easy.
Having flown foamies both home made and bought , 3d and scale I now settled on gliders, I have been obsessed by dlg blaster 2 for the last year or more and love thermalling it even though I can't throw it that high and there are no competitions here in Yorkshire.
Just got the phoenix 2000 gliders and doing my 1st full house setup which is fun.
Biggest move I made recently is going from the spektrum dx6i transmitter which I have used for 4 years to the frsky Taranis.
I will elaborate more later but it was such a revelation to be able to do so much mixing after being limited to 2 mixes on the dx6i, and with a altimeter and vario it has made thermal gliding much more easier and interesting.
Getting my head around the programming was not as hard as I thought it might be but did and does take some thinking about.
rediscovered rc flight a few years ago after 20 year break
