I live on a farm in NW Ohio and we see air tractors flying around us and spraying the fields all the time. In my opinion they look awesome and I have always wanted to build one. This thread will be about me designing and building an air tractor. I am designing it mainly in onshape in 2d and 3d, I plan to make plans for this so it will be easier for me to build it and so all of you guys out there can to! And because I hope to build an erc cutter so I can get a cleaner build.
Design constraints.
-Around a 60 in wing span, or power pack C size
- Ailerons elevator rudder throttle and flaps
-be relatively simple to build
-scalable
-working spray nozzle's, maybe if it fits (;
-looks like the real thing, obviously
- 3d printed landing gear holders to stop the foam from tearing
3d printed scale details exhaust, spray bar, tank, etc
This is my first planed scratch build and first time making plans.
If you are wondering why I chose the AT 402 B its because it has the most 2d style plans for it.
Any tips or ticks are welcome and hopefully by the end of this we will have an air tractor!
