Picture series / photo-guides
The following pictures were typically requested by someone in need of clarification for a certain item or process. These "in-the-field" snapshots were provided in response and can perhaps also be of use to others. This is the spirit in which they are posted here...
QBK Airframe overview (pictures):
|
People often call to find out what the difference is between a standard kit and a Quick-build-kit (QBK). With the standard kit, almost all the parts are made, but there are virtually no pre-assembled elements. As can be seen from the accompanying pictures, most of the airframe is now already assembled in a QBK.
Remains to be installed: The controls and systems (fuel, brakes, electrics, etc.), the engine, instruments and cabin finishing + paint. Assembly time is cut by 300+ hours when building from a QBK... |

QBK airframe kit - transportation:
|
A regular kit can be crated in a single wooden box (approx. approx. 3.75 m. x 1.2 m. x .9 m., 385 kg.) and shipped by truck.
A QBK is too large to be crated. It is recommended that it be picked up on a flat-bed trailer as illustrated here. A container is another option. |

Trim tab installation photos:
|
A number of different trim tabs have been tried on the CH 701 over the years.
In order to have sufficient trim to balance the aircraft in all flight configurations, this virtually full span electrically-operated trim (on one side of the elevator) is now recommended. |

Nose gear bearing details:
|
This green plastic Nyol bearing is designed to lubricate the main nose gear strut as it moves up and down during taxiing.
To further reduce friction in this area, make sure to apply plenty of grease. When well greased, the nose gear strut moves easily and silently in the bearing and steering is effortless. |
        |
Brake cylinder details:
|
The standard kit includes toe brakes for the pilot (left seat). Brakes for the passenger side are an easy to install option.
Contact your representative for assistance. |
   |
Matco calipers details:
|
Matco brakes are sturdy and effective; lighter systems are also available. To confirm what brake system will be supplied, ask at the time of ordering. |
  |
Folding Wing Option details:
|
The folding-wing option has been available for years for the STOL CH 701. It allows the wings to remain attached to the fuselage during the folding process. Time to fold is approx. same as for wing removal (45 min./side); option weight = 15 pounds.

Engine 912 engine mount photo & detail:
|
CH 701 engine mounts are available for the Rotax 912/912S but also for other engine makes and models. Note: Different engines may need a different engine cowl. Ask for availability! |
  |
Throttle installation details:
|
The standard STOL CH 701 throttle system is simple, light-weight, adjustable and included in the standard kit. Other more conventional options are available from aviation shops like ULM Technologie... |
     |
BRS installation details:
|
Yes, the installation of a ballistic recovery system can be done in a STOL CH 701. This should only be undertaken by a knowledgeable person. The parachute is installed at the back of the baggage compartment. We recommend the BRS system because BRS provides all the mounting and installation instructions. |
                |
Bubble Door installation details:
|
Bubble doors are a great addition to the basic STOL CH 701. These doors add 7 cm of shoulder room to each side and allow the pilot/passenger to look straight down. Visibility with these optional doors is simply awesome. Easily retrofittable. Contact your local representative for assistance.
|
        |
Windshield installation details:
|
Installation of the windshield can be a little daunting. Take it one step at a time and it all goes together easily. These pictures will help. Note: This is a Plexiglass windshield (not lexan) so it is stiffer and resistant to fuel, but it is also more brittle. Use caution when drilling, especially in a cold environment. Hot workshop = best... |
                  |
Woodcomp propeller details:
|
Many different type of propellers can be used on the STOL CH 701. Use a propeller that is well adapted to the engine.
In the FWF kit, the Woodcomp propeller was supplied for many years. Others may be supplied now; ask when ordering... |
