Hi guys and girls
Ive got a kit for a Keil Kraft Gypsy which has a 12" plastic prop. Im a firm believer vintage models should have a nice wooden prop , could someone point me in the right direction for mesurements for block size and markings so I can carve one please.

My Gypsy kit came with a saw cut blank that flies the model well. If you are not too competition orientated  I seem to remember that the plan has the sizes for the prop blank.

I agree with you. A nice carved prop is definitely better!

Happy Flying.

OK how much information do you want?? Ha Ha Ha. The Keil Kraft kit used to come with a partially sawn blank 17 x 2 x 1 1/4 inch, this will make a nice prop for a bit of sport flying around the local field. You can go to 17 x 2 1 1/2 inch which is ok for a larger field. The KK plan has a blank 17 x 2 x 1 3/4 inch laid out on it, this prop is for people who are going to wind it up tight ( about 1000 turns on 3 1/2 ounces of rubber) it will give the plane about a 2 1/2 minute capabillity and a long walk! I would suggest the middle of the sizes for your first prop, this has the advantage of being a stock balsa size so you should be able to get it from your local model shop if you have such a thing

Mike Woodhouse offers the KK Gypsy prop - about two-thirds of the way down the page.

Here's a link to it in the HPA gallery, assuming you haven't found it already:

https://www.hippocketaeronautics.com/hpa_plans/details.php?image_id=2633

The path is Home>Model Companies>Keil Kraft (then search the thumbnails).
