2014-05-30 Placing the order
Today I placed my order for an ASH 31 Mi from Paritech!
http://www.paritech.de/modellbau/ash31.php
The first time I laid my eyes on this model was in July 2012 at the Segelflugmesse in Schwabmünchen
after returning from a fantastic glider trip to the Swiss/French Alps with a friend. I was captured not
only by the looks of this ship, but also by the maneuverability displayed by the pilots that were
showing it off to the audience.

Table 1. Paritech ASH 31 Mi specifications.
My previous experience with Paritech is from purchasing an ASH 26 which I’ve flown extensively ever
since the maiden flight in early spring 2011 (https://www.youtube.com/watch?v=b0FpHu54f18). The
build quality of this plane and the in-flight performance has convinced me that Matthias Paul and
Uwe Rihm know their stuff.
After a long period of window shopping and planning of this project I finally pulled the trigger and
placed an order for a “no expense spared” ASH 31 Mi. Having seen how well Paritech assemble their
gliders I could not resist letting them assembling retracts, canopy, cockpit, AFT19XS, spoilers and
rudder.
The purpose of this build log is to provide some ideas of how to assemble this glider.

2014-09-25 Unpacking
After what seems like an eternity I was finally able to meet my new friend at the post terminal in
Årsta, Stockholm. Unpacking was rather nerve wrecking since the prospect of shipping damage
would be unbearable after having waited 4 months for delivery.
Figure 1. 15 kg glider and 65 kg packing material.
After unpacking, the plane was transferred to my car and later my apartment, both of which all the
sudden seem very small.
Figure 2. A trunk full of happiness!
Figure 3. Inspected for shipping damages and
assembled in living room.
Luckily, I could not find any shipping damages and after having assembled the glider in my living
room I started to realize the size of this puppy. The images below show what parts of the build that
I’ve let Paritech take care of.

2014-09-27 Servo connectors between inner wings and fuselage
For whatever reason, I started my build by working on the servo connectors for the wing that
connect to the fuselage. I prefer when servo connectors are fixed to both wings and fuselage. This
avoids fiddling with loose connectors every time it’s time to assemble.
Due to the fact that the inner sections of the wings are not orthogonal to the wing joiner the
connectors need stand-offs to provide the right angle. I made these out of plywood and later painted
them white so that they blend into the wing.
The 9-pin d-sub comes with the wiring harness from PowerBox Systems that Paritech offer. The short
connector frames from Lindinger (http://shop.lindinger.at/product_info.php?products_id=54857) do
a great job securing the multiplex connectors to the wing and fuselage.

Figure 22. Top view showing the angle with respect to the wing joiner.
In order to accurately transfer the location of the connectors from the wings to the fuselage I created
templates from balsa. The wing joiner and together with the positioning pins provide accuracy and
repeatability.
