Elixir refurbishment
I really like the Elixir from Topmodel CZ.
Specifications:
wing span: 3200 mm
length: 1550 mm
weight: 3,1 kg
wing load ~45g/dm2
Easy to fly, very forgiving, pretty good performance for this price segment, nice silhouette in air.
It's my most flown glider (I guess).
If I ever should loose this Elixir I would by another one for sure. But not the ARF version. Only the ARC version to use he high quality Oracstick film.
After flying the Elixir three seasons, often at the slope, she needs some refurbishment.
Especially the film has to be replaced as the wing is blistered again few minutes after every "recover" ironing . Film was not good from the first day. It was definitely no Oracover.
Goals for this (March/April 2013) refurbishment:

EasyStar build with the son
A little miracle has happened.
Some days ago my son asked me to begin the build of his EasyStar
(which I bought a year or two ago for him).
So all other current build activities (Alto carbon, Elixir) are postponed as long as he wants to proceed with the build.

"time killer"
Reason for having only very little time for my main hobby R/C gliders 
...
Most of the time they have no interest in gliders or joining me at the airfield but I also enjoy every common non-R/C second with both as you never know how they will evolve in the future...

Alto Carbon - a 2m leight eight thermal HLG
Yesterday I received my new 2m thermal weapon - the Alto carbon from F5models.
Specifications:
Wing span 2000 mm
Length 1160 mm
Wing Area 32 sq. dm
Airfoil AG 25 mod.
Weight (less R/C gear) 320 g
Control: Ailerons, Rudder, Elevator, Flaps.
Planned operation area is thermal practise in light conditions (before or after work sessions).
My personal R/C glider related aim for 2013 is to increase my thermaling skills so far to succeed with some thermal flights with hand launches on the local airfield (flat land).
This will be pretty challenging as the good thermal locations cannot be reached via hand launches where all the Xplorers and Xperiences begin their thermal flights after high start or aero-towing.
----------------------------------------------------------------------------------------------
Including the already installed highstart hook and all small parts (except bowden cables) she only weights 331g!
On a first view quality is very good.
Perfect surface, the carbon D-box looks great and wings seem to be very strong....Continue Reading

young RC pilots
Spent really great time with my kids at the airfield yesterday!
We used the quite calm time before a storm.
After a long time (9 or 10 months) not interested in Dad's passion, my son made extreme progress flying his EPP Felix.
All flights were "solo" flights with lot of loopings close to the ground and some very promising hoover attempts (with a rudder/elevator only electric glider?! - he saw hoovering at an club internal indoor event 5 months ago).
His little sister wanted to pilot the plane as well, but last flight before pilot change ended with a quite tough "landing" ;-) where EPP Felix lost inter alia his nose including motor and battery.
This was one of the rare moments that made me happy to the core and where I can forget all the bullsh?? around me...
Repair already started to support their current interest in RC activities!!! Everything else that can be postponed has to wait until repair is finished...

2G4 Reciever and 433MHz Variometer
My EasyGlider Pro electric crashed after a minute during flight #2
.
Flight #1 was a great long thermal flight up to 340m.
Few seconds after take-off #2 and switching off the engine, my transmitter noted that there was no return signal from the receiver (Jeti 2G4 TU module in my MC 19 with 8 channel EPC 2G4 receiver, long antennas).
At the same time an uncontrollable short nosedive occured.
I decided to come back and to land promptly.
During the long 400 or 500m final connection got lost again without any control surface reaction and the EG Pro lost 112 m in < 3.2sec in a, at the end, vertical dive.
I assume the fastest Easyglider Pro flight ever :-).
134km/h average speed.
Impact speed could be around 160/170km/h or more as the ship had to accelerate from normal flight speed and came down in type of a half parable...
No flutter and a flight like on rails. Very good high speed test results of my EasyGlider Pro mods ;-)!
Everything points to a Jeti receiver issue as it was definitely no pilot error...
Reason to be analyzed!
Killed:
8 channel EPC Jeti Receiver
speed controller Kontronik Jazz 55
motor Turnigy C3536 -1100
EasyGlider Pro
2 HS-82MG servos, 4 wing servos to be checked
3S1P 2200 mAh Lemon...Continue Reading

Slowing down a Flying Plank for landing
Several times I was asked what I do to slow down my Flying Planks for landing.
I use crow function.
For a plank which is very CG and elvator sensitive this setup is not an easy job. So do it only when you enough air under the wing!
But when its done, it's really helpfull. Especially when you have to land on small landing zones...

Helmet Cam
With a view to the coming F3F competitions it became more important to get a chance to analyse my weak F3F flying style.
Most of the time when I fly, I have nobody around me who takes a video from my flight attempts or has at least F3F related knowledge to tell me what has to be changed or improved.
Ok, but what's better than taking videos? In my case I assume nothing...
What to do to follow the plane with a video cam when you have to do both - flying and shooting?
Putting the cam on my head!
Here is my first attempt with my regular cam as there is currently no budget for an additonal small cam available.
Today (2011-02-18) I did a second check flight in the backyard as the camera angle was a bit too high for the first attempt.
Result is quite good and I now have to finish my F3F planes to test the construction at the slope.
Addendum March, 1st 2011:
Meanwhile I had the chance to test my Helmetcam configuration.
After reducing the camera angle by 7° downwards everything works fine.
For the future videos I have to switch-off the autofocus system as "fast" moves without a clear reference point lead to significant fuzziness.
final check (checking F3F appropriate distance/altitude flying)
1st re-check (camera angle reduced by 7°, checking short distance flying)
