This build log is of [ Otto Dieffenbach's ] second Broom Flyer build, a Witch.
It differs from the first build incorporating improvements from lessons learned ...
This is a difficult build and should not be attempted by a newcomer to the hobby.
There is a lot of wood work involved.
You may want to find a friend with superior build skills if you are a newcomer.
The Broom Flyer has a low wing loading (6 oz per sqft) and is a gentle flyer.
Anybody that can fly a trainer can fly this craft.
It has a basic rudder and elevator control setup and will turn on a dime.
Stalls are gentle and you can almost hover in a deep stall.
Landing speed is quite slow and with a little headwind you can land with zero ground speed.
The negative of this design is the landing undercarriage.
I did not want to erode the illusion so I put the main landing gear/wheels inside the knees.
They are not spread apart, so he/she always tips over after landing.
This has not caused any damage to date.
What is an issue is the rotation caused by the knees when they touch down.
The rotation causes the broom stick to rotate downward at a high angular rate and has cracked some Depron.
To solve this issue, I added a removable nose skid on the original and a retractable skid on the second build.
Cutouts of the Depron components are available from http://www.hoosiercutoutservice.com/.
I recommend you read through the whole build log before committing yourself to this project.
...
Getting everything you need and prepare the cutouts.
If you get your cutouts from Hooiser Cutout Service, separate them form their sheets, identify each part and lightly sand the edges with 150 grit sandpaper.
Save the extra material.
