About this Plan

Hatchetman. Nordic A/1 class glider. From July 1957 Aeromodeller.

Quote: "Are you flying the A/1 class? Try this simpleton for easy building, straight towing and fine all-weather performance. Hatchetman, by J Roderick.

HATCHETMAN is the third of a series of A/1s. Development has resulted in a sturdy quick-to-build mode! with a good performance. In calm evening air 1 min 40 sec is readily achieved from a 164 ft tow-line. A figure that can be considerably improved when thermals are present. It will be found that the 'Hatchet' fuselage configuration gives excellent two line stability even in rough weather, a must for consistent performance.

The beginner with one or two models to his credit or the more experienced modeller will find ample repayment for the little time and cost spent upon building Hatchetman. The drawing is practically self-explanatory but for the benefit of the less experienced the following notes are offered.

Wing. The wing is built flat on the plan. Pin down leading and trailing edges, not forgetting to pack up the front of the TE 1/16 in. Cement in the ribs and tip ribs then add the rnainspar. Cut through the wing at the dihedral breaks. Chamfer the ends of the leading edge, mainspar and trailing edge to ensure a good fit and insert dihedral. Add the ply dihedral keepers; it is necessary to use pre-cement-ing here. When the dihedral is firmly set take up the wing and add the lower spars.

Fuselage. Build the basic framework from balsa. Add gussets and the tow hook which should be bound with thread. Sheet both sides with 1/16 in soft balsa. Add noseblock, dowels, and wing and tail platforms. Cover with lightweight Modelspan then add fin and rudder and the aluminium tubing.

Tail. No difficulty should be found if the T3 ribs are cemented in first. Cover wing and tail with lightweight modelspan. Give wing and fuselage two coats of a mixture one third thinners two-thirds dope and the tail one coat.

Trimming. Check for correct balance and warp free wings before trimming. For best results use strips torn from a cigarette packet for packing pieces. Trim should be fairly tight left circles add an extra packing strip in windy weather to maintain trim.

One point to watch, never use a too powerful band on the auto-rudder or the rudder will take over while towing and it will be impossible to gain full height.

Don't forget your name and address label and don't forget the dethermaliser. They are necessary."

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.
