Drawings
Some of the drawings listed below are suitable for those who design their own models, and like to include vital parts in the drawings. Others are of more specific items for modeling that each and everyone can make for themselves. All the drawings are in DXF-format (DrawingExchangeFile), a format possible to import into most SW-packages.
Plane(s).
- Spigas 3 : Basic aerobatic model for 40-50 size engine.
- Spigas 5 : My last for a.60 size engine.
- Spigas E : Basically a Spigas 90 made with a balsa fuselage, to make installation of electric motor and batteries easier.
Engines and exhaust
- OS 140 RX : The 2-stroke for F3A
- Webra 120R : The first available 'big' 2-stroke for F3A, the case is the same as the Webra 145R, and the rear exhaust Bully engines assembled in USA.
- YS 120SF : The original YS 4-stroke, the newer 140's are almost exactly the same size.
- OS 61RFP : The king from the 60-size 2-stroke era.
- OS 46VF : Older rear exhaust OS.
- Bolly EQ-60 : Super-light, very quiet pipe for 60 engines, still available.
- Extra-muffler : Fremming design extra-muffler with very low resistance and excellent noise reducing. Works by canceling of opposite phase sound waves.
Radio equipment
- Futaba 9101 : Standard-size servo.
- Futaba 9102 : Low-profile servo.
Bits and pieces
All these drawings are made to be used by a SW made (by myself) to mill the pieces on a small CNC mill that we have at work. The pieces will end up in correct size if a 1mm routing milling tool is moved along the lines.
When using MK's 'Dual BB
coupler' on elevators, this piece made of fiberglass PCB (Printed Circuit
Board) attached to the center unit of the coupler, enables the use of
wire pull-pull from the servo to the coupler. The use of wires avoids
problems with temperature- trinduced trim changes etc. DXF-drawing
