About this Plan

Arrowhead. Tailless hand launched glider with built-up wing designed by JT Holmes. January 1947 Air World.

Quote: "GO AHEAD take a second look! It's just what you think it is... a tailless hand launch glider. A built up one at that. Think it won't fly? Well you better think twice because this ship will perform as well as any conventional design - maybe better. It's easy to build and economical, so why not start now.

The wing is constructed in the usual manner. The ribs are cut from 1/16 sheet balsa with the leading edge, spar and trailing edge placed on the plan in their respective positions and held there by straight pins. After this is done, glue ribs in place and let the asssembly dry for an hour or so.

In the meantime, carve the body from a hard piece of 3/16 sheet balsa and the rudder from a medium piece of 1/8 sheet balm. Remove the wing halves from the plan and glue together. Insert dihedral brace and be sure there is 1/4in dihedral at each tip. Proceed to cover the wing with either tissue or light silkspan..."

User comments

Hi, I have just built this model and found that the slots in rib 2 & 3 are not in the right place to align with the false spar when each rib is located on the main spar, i.e. the spacing between the slots is not correct. Other than that, this plan builds into a pretty little chuckie that flies quite well.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
