** Note: HP laser printer drivers on Mac laptops may not print at the needed 1:1 scale, no matter what software you use or what you do in the print settings. Exact same file, printer and Adobe Reader are able to print at 1:1 scale on a Windows laptop. There might be an issue on Macs. | ** Note: HP laser printer drivers on Mac laptops may not print at the needed 1:1 scale, no matter what software you use or what you do in the print settings.

** Hint for Onshape users: You can import a pdf page via Inkscape. Import the pdf page in Inkscape and save it out as dxf v14 file. Import that dxf file into Onshape. Start a new sketch. Add the dxf drawing to the sketch. Take a known distance between two points and call out a dimension between them. It will show the distance as it imported the drawing. You can now override that distance to the known distance and the whole dxf is now at scale. You can now overlay your own drawing while the endpoints will snap to the dxf points. Next, create a drawing within Onshape and add the sketch. You can then export that drawing back to a pdf and the scale is correct. | ** Hint for Onshape users: You can import a pdf page via Inkscape.

* Step 1: The bearing surface is between the outer side of the bushing and the inside of the base pivot tube. Therefore, it doesn't matter if the bolt sits tight inside the bushing, it's actually good if it sits tight. Be careful removing burrs from the inside of the base pivot tube. The play between the bushing and the base pivot tube must be minimal. Consider adding grease to the outside of the brass bushing (e.g. [https://www.aircraftspruce.com/catalog/eppages/aerogrease22.php Aeroshell #22] which is also later needed for the wheel bearings). | * Step 1: The bearing surface is between the outer side of the bushing and the inside of the base pivot tube.

* Step 3: If you install an Aerosport 310 panel, you probably will have interference between the grip and the panel. Also, if you opted to let the elevator travel reach its maximum angle of 25 degrees down (only 20 down is required, see first flight section), even the stock panel might interfere with a grip (especially the Tosten 8 button since it is tilted forward).<br>To fix the grip interference, a lot of builders bend the control stick with e.g. a hydraulic HF tube bender (don't forget to fill the tube with sand). However, then, the elevator all up position might interfere with the pilot / passenger with the seats in the front 3 notches, especially, if you opted to let the elevator travel reach its maximum angle of 30 degrees up (only 25 up is required).
