Thank you for acquiring a new Passion!
Passion is a sophisticated model and will reward your build skills with a unique flying experience full
of performance and great handling while being elegant in the air.
I hope you enjoy building this kit as much as we did developing it. This kit is part of the first batch
ever produced hence your feedback is very much appreciated. In case you find some difficulty,
defect or would like to suggest improvements, please message us info@pichler.com
Have fun!
You are an experienced modeler and may build the model in a different approach than ours however,
please find below some build advice. We hope it serves to guide you along the process.
BUILDING ADVICE
1. This kit is not recommended for beginner's
2. This is a very high performance glider, hence accuracy is very important to extract its
potential.
3. Study the plans and instructions before starting.
4. Only remove parts you are about to use from laser-cut sheets.
5. Use wood glue as much as possible.
6. Use CA when gluing carbon to balsa.
7. Use lightweight (~34g/m2) covering all over.
8. Paint or cover the fuselage pod.
9. Use pin or live hinges, if possible.
10. Make sure there is no friction or play in your linkage.
11. Build carefully. This model will be your partner for many years.
12. Take the time to sand parts to shape and enjoy the building process.
13. Repeat step 3.
FLYING
This model is designed to extract the maximum performance from 3m REF. Trim the model to your
preference and explore the speed envelope in detail; it can fly slower than you might anticipate.
Adjust the CG to your preference. Balance the model 20mm behind the main spar to produce a
stable but very controllable glider. I tend to favor great handling qualities over steady-state glide
performance. Flaps can be used to partially modify camber, negative 3mm for high speed, and
positive 6mm for low speed, which will produce a small performance increase over fixed positions.
It is important that the model is built light for calm conditions such as morning and evening flights or
very low thermal flying. However, it is advised to use ballast as wind and thermal activity increases.
The carbon wing joiner can be replaced by an 8mm brass rod. It is suggested one length of 400mm
and two of 200mm each. This way, one may use none, 50%, or full ballast (~340g).
Mix flap to elevator to ensure the model is neutral with flap deployment. The model is designed to fly
a wide speed range, but it is not indestructible. Avoid extreme speeds during flights, as they may
cause control loss. THIS IS NOT A BEGINNER'S MODEL!
If extreme power is installed, ensure full power is used only while the model climbs to avoid too high
speeds. If altitude has to be reduced quickly, deploy the flaps fully (45deg or more) and then dive
steeply. If you become disoriented during flight, deploy the flaps fully and release the controls.
