Quickbuild style Mirage F1

Here is my quickbuild style Mirage F1. (Thanks for the inspiration Tomhe).

It was designed in Google Sketchup for 6mm depron and the standard 6” prop power set-ups. I used only elevons, which seem to work fine, simplifies construction and keeps the weight down.

The rounded intake shape is very simply made from thin plastic sheet.

Details:
Span: 25”
Length: 42”
Flying weight: 14oz (light build, 2208 motor, 1250mah 3s battery)
Prop slot fits 6” props.

Control throws (measured as shown in picture):
Elevator: 40mm up/40mm down. 30% Expo
Aileron: 60mm up/60mm down. No expo.


The first flights went very well. The plane is stable and tracks straight. Rolls are very straight also. The roll rate with only elevons seems adequate for my “scale” flying style. As with the full size plane, all-out manoeuvrability is not the model’s strong point.

I have not checked the stall behaviour yet, but it slows down well for easy landings.

On the building side:

* As always, a light plane will fly better, particularly when it has small wings like the F1.
* The wings will need some stiffening with spars of your choice, but take care to ensure that all the tabs still line up. Make sure that the wing root joint is strong, as the wing is not continuous due to the anhedral.
* Size the motor cut-outs for your choice of motor and motor mount.
* Take a bit of time before assembly to figure out how you will mount the electronics. Cut slots for wires and velcro straps before assembly, access is limited afterwards.

Good luck

Good work, could you post 100% and 200% scale plans of the jet?
