ASW 17 Sailplane

Bad luck that seems very unfortunate!
My rule is to test any servo before installation, then again as soon as I make any joint to it and then twice more before anything is permanently built in. Colour coded servo wire?
Great care is needed wiring up multiple pin wing connectors!
I have "fried" ESCs, motors and even a couple of RXs but never, so far, a servo tester.
 

The clue might be
the multi meter which I know nothing about
Most have three sockets, the common, the voltage and the current. The voltage is high resistance, the current is low resistance (ie short circuit). Never leave the lead in the current one, its too easy to just pick them up & voila.........smoke.

 I did test each section of wire as i went on, iv just spent hour and a half going through it all, all of the connections as far as i could see were ok, think i label them wrong at the Rx end. i cut the wing open at the root where the multi pin plug is but i checked it with the multi meter and was getting a reading when touching both ends of the wire
And i know the servo i used works
So i might try it connected to a Rx and see that way as iv no servo tester 

If you have a short circuit in the wiring  (+ connected to -) rather than a simple wire break then it wont do the receiver much good either.

Iv checked and double checked there is no cross wiring as i can see the connections with the wing opened up

Been out in the shed on and of during the day but not much to show for it as i had another bad night one good thing it was warmer at half three this morning as i turned the heater off after 15 minutes, and it was good to see the rain coming down this afternoon, dont like rain but prefer it to snow
Iv got all the wiring installed and working ok, just got the wings to finish off then get it ready for glassing the fuselage, think ill use tape for hinges, never used it before but it seems most glider flyers use it

A tape as a hinge does have limitations particularly if the ailerons are long and the wing is somewhat flexible. When the wing bends it has to bend the aileron as well. Doing that can cause the tape to start to unpeel whereas fixed hinges can better resist such forces. As Klippy points out on full size sealing the gap is independent of hinge.

Having said all that I do tend to use full length "top tape" hinge as it not only seals the joint but provides a smooth top surface which is more critical for aerodynamics than the under side. It is also one of the reasons I favour short ailerons out towards the wing tip as they are less effected by any wing bending!

The example I quote for top tape ailerons is with my Depron Super Cub. Built in 2017 and still with its original tape.
 
Under the paint you are hard put to see or even feel the aileron hinge line.   

With little else to do i decided to fit the canopy or cut it to size to fit the frame
 
Took me ages to get it right and not cock it up, ill glue it on when iv done the painting
I picked up the fuselage to rub down the filler i put on last nights, and put my finger straight through it   the 3mm balsa planking has got quite thing in places with the sanding down

Just my usual luck Erik
I think i read somewhere you can get hinge gap seals for models

After another sleepless night, the pills the doc gave to help me sleep dont work, been in the shed this morning thought i would fit 1/64 ply facings on the wing roots that fit to the fuselage 
The first thing i did after getting the wing off the shelf was to poke my finger through it, then i marked the ply cut the tried the wing on the fuselage the plug would not engage with the other half, this wing has been on and off several times and was always in line, when i glued it all in place originally the wing was in place on the fuselage and all was connected
 
So having corrected that wing i got the other one and it slid on ok
Only thing wrong was my finger went through it
Using light weight competition balsa to keep the weight down is not a good idea for me i think
Surprising just how much glue is used to build this 
 
I started with the new large bottle and iv just put all the remaining contents into the small one, it just filled it
 

Had to join a piece on to the flaps as the 900mm 36" long lengths were short, its a job now days to find 1200 long balsa, Slec do it but only in medium and hard
 
Finally got the wings done with no finger holes poked in and the ply facings on the ends, just the airbrakes to do, if i do them, i dont suppose they do much stopping 
 
loooong narrow wings 2M each and only 150mm wide
